Complications of pregnancy are health problems that occur during pregnancy. They can involve the mother’s health, the baby’s health, or both. Some women have health problems that arise during pregnancy, and other women have health problems before they become pregnant that could lead to complications. It is very important for women to receive health care before and during pregnancy to decrease the risk of pregnancy complications.

Before Pregnancy

Make sure to talk to your doctor about health problems you have now or have had in the past. If you are receiving treatment for a health problem, your health care provider might want to change the way your health problem is managed. For example, some medicines used to treat health problems could be harmful if taken during pregnancy. At the same time, stopping medicines that you need could be more harmful than the risks posed should you become pregnant. In addition, be sure to discuss any problems you had in any previous pregnancy. If health problems are under control and you get good prenatal care, you are likely to have a normal, healthy baby.

During Pregnancy

Pregnancy symptoms and complications can range from mild and annoying discomforts to severe, sometimes life-threatening, illnesses. Sometimes it can be difficult for a woman to determine which symptoms are normal and which are not. Problems during pregnancy may include physical and mental conditions that affect the health of the mother or the baby. These problems can be caused by or can be made worse by being pregnant. Many problems are mild and do not progress; however, when they do, they may harm the mother or her baby. Keep in mind that there are ways to manage problems that come up during pregnancy. Always contact your prenatal care provider if you have any concerns during your pregnancy.

The following are some common maternal health conditions or problems a woman may experience during pregnancy—

Anemia
Anemia is having lower than the normal number of healthy red blood cells. Treating the underlying cause of the anemia will help restore the number of healthy red blood cells. Women with pregnancy related anemia may feel tired and weak. This can be helped by taking iron and folic acid supplements. Your health care provider will check your iron levels throughout pregnancy.

Urinary Tract Infections(UTI)
A UTI is a bacterial infection in the urinary tract. You may have a UTI if you have—

• Pain or burning when you use the bathroom.
• Fever, tiredness, or shakiness.
• An urge to use the bathroom often.
• Pressure in your lower belly.
• Urine that smells bad or looks cloudy or reddish.
• Nausea or back pain.

If you think you have a UTI, it is important to see your health care provider. He/she can tell if you have a UTI by testing a sample of your urine. Treatment with antibiotics to kill the infection will make it better, often in one or two days. Some women carry bacteria in their bladder without having symptoms. Your health care provider will likely test your urine in early pregnancy to see if this is the case and treat you with antibiotics if necessary.

Mental Health Conditions
Some women experience depression during or after pregnancy. Symptoms of depression are:

• A low or sad mood.
• Loss of interest in fun activities.
• Changes in appetite, sleep, and energy.
• Problems thinking, concentrating, and making decisions.
• Feelings of worthlessness, shame, or guilt.
• Thoughts that life is not worth living.

When many of these symptoms occur together and last for more than a week or two at a time, this is probably depression. Depression that persists during pregnancy can make it hard for a woman to care for herself and her baby. Having depression before pregnancy also is a risk factor for postpartum depression. Getting treatment is important for both mother and baby. If you have a history of depression, it is important to discuss this with your health care provider early in pregnancy so that a plan for management can be made.

Hypertension(High Blood Pressure)
Chronic poorly-controlled high blood pressure before and during pregnancy puts a pregnant woman and her baby at risk for problems. It is associated with an increased risk for maternal complications such as preeclampsiaexternal icon, placental abruption (when the placenta separates from the wall of the uterus), and gestational diabetes. These women also face a higher risk for poor birth outcomes such as preterm delivery, having an infant small for his/her gestational age, and infant death. The most important thing to do is to discuss blood pressure problems with your provider before you become pregnant so that appropriate treatment and control of your blood pressure occurs before pregnancy. Getting treatment for high blood pressure is important before, during, and after pregnancy.

Diabetes During Pregnancy

Learn about types of diabetes during pregnancy, the percentage of women affected, and what CDC is doing to address this important health topic. Managing diabetes can help women have healthy pregnancies and healthy babies.

Obesity and Weight Gain
Recent studies suggest that the heavier a woman is before she becomes pregnant, the greater her risk of pregnancy complications, including preeclampsia, GDM, stillbirth and cesarean delivery. Also, CDC research has shown that obesity during pregnancy is associated with increased use of health care and physician services, and longer hospital stays for delivery. Overweight and obese women who lose weight before pregnancy are likely to have healthier pregnancies.

Infections
During pregnancy, your baby is protected from many illnesses, like the common cold or a passing stomach bug. But some infections can be harmful to you, your baby, or both. Easy steps, such as hand washing, and avoiding certain foods, can help protect you from some infections. You won’t always know if you have an infection—sometimes you won’t even feel sick. If you think you might have an infection or think you are at risk, see your health care provider.

Infections with HIV, viral hepatitis, STDs, and TB can complicate pregnancy and may have serious consequences for a woman, her pregnancy outcomes, and her baby. Screening and treatment for these infections, and vaccinations against viruses, such as hepatitis B and human papillomavirus, can prevent many bad outcomes.

Hyperemesis Gravidarum
Many women have some nausea or vomiting, or “morning sickness,” particularly during the first 3 months of pregnancy. The cause of nausea and vomiting during pregnancy is believed to be rapidly rising blood levels of a hormone called HCG (human chorionic gonadotropin), which is released by the placenta. However, hyperemesis gravidarum occurs when there is severe, persistent nausea and vomiting during pregnancy—more extreme than “morning sickness.” This can lead to weight loss and dehydration and may require intensive treatment.

Some women experience health problems during pregnancy. These complications can involve the mother's health, the fetus's health, or both. Even women who were healthy before getting pregnant can experience complications. These complications may make the pregnancy a high-risk pregnancy.

Getting early and regular prenatal care can help decrease the risk for problems by enabling health care providers to diagnose, treat, or manage conditions before they become serious. Prenatal care can also help identify mental health concerns related to pregnancy, such as anxiety and depression.

Some common complications of pregnancy include, but are not limited to, the following.

High Blood Pressure

High blood pressure, also called hypertension, occurs when arteries carrying blood from the heart to the body organs are narrowed. This causes pressure to increase in the arteries. In pregnancy, this can make it hard for blood to reach the placenta, which provides nutrients and oxygen to the fetus. Reduced blood flow can slow the growth of the fetus and place the mother at greater risk of preterm labor and preeclampsia.

Women who have high blood pressure before they get pregnant will continue to have to monitor and control it, with medications if necessary, throughout their pregnancy. High blood pressure that develops in pregnancy is called gestational hypertension. Typically, gestational hypertension occurs during the second half of pregnancy and goes away after delivery.

Gestational Diabetes

Gestational diabetes occurs when a woman who didn't have diabetes before pregnancy develops the condition during pregnancy.

Normally, the body digests parts of your food into a sugar called glucose. Glucose is your body's main source of energy. After digestion, the glucose moves into your blood to give your body energy.

To get the glucose out of your blood and into the cells of your body, your pancreas makes a hormone called insulin. In gestational diabetes, hormonal changes from pregnancy cause the body to either not make enough insulin, or not use it normally. Instead, the glucose builds up in your blood, causing diabetes, otherwise known as high blood sugar.

Managing gestational diabetes, by following a treatment plan outlined by a health care provider, is the best way to reduce or prevent problems associated with high blood sugar during pregnancy. If not controlled, it can lead to high blood pressure from preeclampsia and having a large infant, which increases the risk for cesarean delivery.

Infections

Infections, including some sexually transmitted infections (STIs), may occur during pregnancy and/or delivery and may lead to complications for the pregnant woman, the pregnancy, and the baby after delivery. Some infections can pass from mother to infant during delivery when the infant passes through the birth canal; other infections can infect a fetus during the pregnancy. Many of these infections can be prevented or treated with appropriate pre-pregnancy, prenatal, and postpartum follow-up care.

Some infections in pregnancy can cause or contribute to:

• Pregnancy loss/miscarriage (before 20 weeks of pregnancy)
• Ectopic pregnancy (when the embryo implants outside of the uterus, usually in a fallopian tube)
• Preterm labor and delivery (before 37 completed weeks of pregnancy)
• Low birth weight
• Birth defects, including blindness, deafness, bone deformities, and intellectual disability
• Stillbirth (at or after 20 weeks of pregnancy)
• Illness in the newborn period (first month of life)
• Newborn death
• Maternal health complications

If you are planning to get pregnant, talk with your health care provider about getting vaccines and vaccine boosters for chicken pox (also called varicella) and rubella (also called German measles) before you conceive. You can also get some vaccines, such as the flu shot, while you are pregnant. If you know you have an infection, such as an STI, talk with your health care provider about it before you conceive to increase your chances of a healthy pregnancy.

Early prenatal testing for STIs and other infections can determine if the infection can be cured with drug treatment. Or, if you know you have an infection, tell your pregnancy health care provider about it as early as possible in your pregnancy. Early treatment decreases the risk to the fetus and infant. Even if the infection can't be cured, you and your health care provider can take steps to protect your health and your infant's health.

Preeclampsia

Preeclampsia is a serious medical condition that can lead to preterm delivery and death. Its cause is unknown, but some women are at an increased risk. Risk factors include:

• First pregnancies
• Preeclampsia in a previous pregnancy
• Existing conditions such as high blood pressure, diabetes, kidney disease, and systemic lupus erythematosus
• Being 35 years of age or older
• Carrying two or more fetuses
• Obesity

Preterm Labor

Preterm labor is labor that begins before 37 weeks of pregnancy. Any infant born before 37 weeks is at an increased risk for health problems, in most cases because organs such as the lungs and brain finish their development in the final weeks before a full-term delivery (39 to 40 weeks).

Certain conditions increase the risk for preterm labor, including infections, developing a shortened cervix, or previous preterm births.

Progesterone, a hormone produced naturally during pregnancy, may be used to help prevent preterm birth in certain women. A 2003 study led by NICHD researchers found that progesterone supplementation to women at high risk for preterm delivery due to a prior preterm birth reduces the risk of a subsequent preterm birth by one third.

Depression & Anxiety

Research shows that as many as 13% of U.S. women reported frequent symptoms of depression after childbirth, and that anxiety co-occurs in up to 43% of depressed pregnant and postpartum women, making pregnancy-related depression and anxiety among the more common pregnancy complications. These medical conditions can have significant effects on the health of the mother and her child. But the good news is that these are treatable medical conditions.

Pregnancy Loss/Miscarriage

Miscarriage is the term used to describe a pregnancy loss from natural causes before 20 weeks. Signs can include vaginal spotting or bleeding, cramping, or fluid or tissue passing from the vagina. However, bleeding from the vagina does not mean that a miscarriage will happen or is happening. Women experiencing this sign at any point in their pregnancy should contact their health care provider.

Stillbirth

The loss of pregnancy after the 20th week of pregnancy is called a stillbirth. In approximately half of all reported cases, health care providers can find no cause for the loss. However, health conditions that can contribute to stillbirth include chromosomal abnormalities, placental problems, poor fetal growth, chronic health issues of the mother, and infection.

Other Complications

Other complications of pregnancy may include the following:

• Severe, persistent nausea and vomiting. Although having some nausea and vomiting is normal during pregnancy, particularly in the first trimester, some women experience more severe symptoms that last into the third trimester.
  
  The cause of the more severe form of this problem, known as hyperemesis gravidarum (pronounced HEYE-pur-EM-uh-suhss grav-uh-DAR-uhm), is not known. Women with hyperemesis gravidarum experience nausea that does not go away, weight loss, reduced appetite, dehydration, and feeling faint.
  
  Affected women may need to be hospitalized so that they can receive fluids and nutrients. Some women feel better after their 20th week of pregnancy, while others experience the symptoms throughout their pregnancy.
• Iron-deficiency anemia. Pregnant women need more iron than normal for the increased amount of blood they produce during pregnancy. Iron-deficiency anemia—when the body doesn't have enough iron—is somewhat common during pregnancy and is associated with preterm birth and low birth weight. Symptoms of a deficiency in iron include feeling tired or faint, experiencing shortness of breath, and becoming pale. ACOG recommends 27 milligrams of iron daily (found in most prenatal vitamins) to reduce the risk for iron-deficiency anemia. Some women may need extra iron through iron supplements. Your health care provider may screen you for iron-deficiency anemia and, if you have it, may recommend iron supplements.

Before pregnancy, make sure to talk to your doctor about health problems you have now or have had in the past. If you are receiving treatment for a health problem, your doctor might want to change the way your health problem is managed. Some medicines used to treat health problems could be harmful if taken during pregnancy. At the same time, stopping medicines that you need could be more harmful than the risks posed should you become pregnant. Be assured that you are likely to have a normal, healthy baby when health problems are under control and you get good prenatal care.

What is asthma?

Asthma is a chronic (long-term) lung disease. It affects your airways, the tubes that carry air in and out of your lungs. When you have asthma, your airways can become inflamed and narrowed. This can cause wheezing, coughing, and tightness in your chest. When these symptoms get worse than usual, it is called an asthma attack or flare-up.

What causes asthma?

The exact cause of asthma is unknown. Genetics and your environment likely play a role in who gets asthma.

An asthma attack can happen when you are exposed to an asthma trigger. An asthma trigger is something that can set off or worsen your asthma symptoms. Different triggers can cause different types of asthma:

• Allergic asthma is caused by allergens. Allergens are substances that cause an allergic reaction. They can include
  • Dust mites
  • Mold
  • Pets
  • Pollen from grass, trees, and weeds
  • Waste from pests such as cockroaches and mice
• Nonallergic asthma is caused by triggers that are not allergens, such as
  • Breathing in cold air
  • Certain medicines
  • Household chemicals
  • Infections such as colds and the flu
  • Outdoor air pollution
  • Tobacco smoke
• Occupational asthma is caused by breathing in chemicals or industrial dusts at work
• Exercise-induced asthma happens during physical exercise, especially when the air is dry

Asthma triggers may be different for each person and can change over time.

Who is at risk for asthma?

Asthma affects people of all ages, but it often starts during childhood. Certain factors can raise your risk of having asthma:

• Being exposed to secondhand smoke when your mother is pregnant with you or when you are a small child
• Being exposed to certain substances at work, such as chemical irritants or industrial dusts
• Genetics and family history. You are more likely to have asthma if one of your parents has it, especially if it's your mother.
• Race or ethnicity. Black and African Americans and Puerto Ricans are at higher risk of asthma than people of other races or ethnicities.
• Having other medical conditions such as allergies and obesity
• Often having viral respiratory infections as a young child
• Sex. In children, asthma is more common in boys. In teens and adults, it is more common in women.

What are the symptoms of asthma?

The symptoms of asthma include

• Chest tightness
• Coughing, especially at night or early morning
• Shortness of breath
• Wheezing, which causes a whistling sound when you breathe out

These symptoms can range from mild to severe. You may have them every day or only once in a while.

When you are having an asthma attack, your symptoms get much worse. The attacks may come on gradually or suddenly. Sometimes they can be life-threatening. They are more common in people who have severe asthma. If you are having asthma attacks, you may need a change in your treatment.

How is asthma diagnosed?

Your health care provider may use many tools to diagnose asthma:

• Physical exam
• Medical history
• Lung function tests, including spirometry, to test how well your lungs work
• Tests to measure how your airways react to specific exposures. During this test, you inhale different concentrations of allergens or medicines that may tighten the muscles in your airways. Spirometry is done before and after the test.
• Peak expiratory flow (PEF) tests to measure how fast you can blow air out using maximum effort
• Fractional exhaled nitric oxide (FeNO) tests to measure levels of nitric oxide in your breath when you breathe out. High levels of nitric oxide may mean that your lungs are inflamed.
• Allergy skin or blood tests, if you have a history of allergies. These tests check which allergens cause a reaction from your immune system.

What are the treatments for asthma?

If you have asthma, you will work with your health care provider to create a treatment plan. The plan will include ways to manage your asthma symptoms and prevent asthma attacks. It will include

• Strategies to avoid triggers. For example, if tobacco smoke is a trigger for you, you should not smoke or allow other people to smoke in your home or car.
• Short-term relief medicines, also called quick-relief medicines. They help prevent symptoms or relieve symptoms during an asthma attack. They include an inhaler to carry with you all the time. It may also include other types of medicines which work quickly to help open your airways.
• Control medicines. You take them every day to help prevent symptoms. They work by reducing airway inflammation and preventing narrowing of the airways.

If you have a severe attack and the short-term relief medicines do not work, you will need emergency care.

Your provider may adjust your treatment until asthma symptoms are controlled.

Sometimes asthma is severe and cannot be controlled with other treatments. If you are an adult with uncontrolled asthma, in some cases your provider might suggest bronchial thermoplasty. This is a procedure that uses heat to shrink the smooth muscle in the lungs. Shrinking the muscle reduces your airway's ability to tighten and allows you to breathe more easily. The procedure has some risks, so it's important to discuss them with your provider.

Depression is a serious medical illness. It's more than just a feeling of being sad or "blue" for a few days. If you are one of the more than 19 million teens and adults in the United States who have depression, the feelings do not go away. They persist and interfere with your everyday life. Symptoms can include

• Feeling sad or "empty"
• Loss of interest in favorite activities
• Overeating, or not wanting to eat at all
• Not being able to sleep, or sleeping too much
• Feeling very tired
• Feeling hopeless, irritable, anxious, or guilty
• Aches or pains, headaches, cramps, or digestive problems
• Thoughts of death or suicide

Depression is a disorder of the brain. There are a variety of causes, including genetic, biological, environmental, and psychological factors. Depression can happen at any age, but it often begins in teens and young adults. It is much more common in women. Women can also get postpartum depression after the birth of a baby. Some people get seasonal affective disorder in the winter. Depression is one part of bipolar disorder.

There are effective treatments for depression, including antidepressants, talk therapy, or both.

Diabetes is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose comes from the foods you eat. Insulin is a hormone that helps the glucose get into your cells to give them energy. With type 1 diabetes, your body does not make insulin. With type 2 diabetes, the more common type, your body does not make or use insulin well. Without enough insulin, the glucose stays in your blood. You can also have prediabetes. This means that your blood sugar is higher than normal but not high enough to be called diabetes. Having prediabetes puts you at a higher risk of getting type 2 diabetes.

Over time, having too much glucose in your blood can cause serious problems. It can damage your eyes, kidneys, and nerves. Diabetes can also cause heart disease, stroke and even the need to remove a limb. Pregnant women can also get diabetes, called gestational diabetes.

Blood tests can show if you have diabetes. One type of test, the A1C, can also check on how you are managing your diabetes. Exercise, weight control and sticking to your meal plan can help control your diabetes. You should also monitor your blood glucose level and take medicine if prescribed.

What are eating disorders?

Eating disorders are serious mental health disorders. They involve severe problems with your thoughts about food and your eating behaviors. You may eat much less or much more than you need.

Eating disorders are medical conditions; they are not a lifestyle choice. They affect your body's ability to get proper nutrition. This can lead to health issues, such as heart and kidney problems, or sometimes even death. But there are treatments that can help.

What are the types of eating disorders?

Common types of eating disorders include

• Binge-eating, which is out-of-control eating. People with binge-eating disorder keep eating even after they are full. They often eat until they feel very uncomfortable. Afterward, they usually have feelings of guilt, shame, and distress. Eating too much too often can lead to weight gain and obesity. Binge-eating disorder is the most common eating disorder in the U.S.
• Bulimia nervosa. People with bulimia nervosa also have periods of binge-eating. But afterwards, they purge, by making themselves throw up or using laxatives. They may also over-exercise or fast. People with bulimia nervosa may be slightly underweight, normal weight, or overweight.
• Anorexia nervosa. People with anorexia nervosa avoid food, severely restrict food, or eat very small quantities of only certain foods. They may see themselves as overweight, even when they are dangerously underweight. Anorexia nervosa is the least common of the three eating disorders, but it is often the most serious. It has the highest death rate of any mental disorder.

What causes eating disorders?

The exact cause of eating disorders is unknown. Researchers believe that eating disorders are caused by a complex interaction of factors. These include genetic, biological, behavioral, psychological, and social factors.

Who is at risk for eating disorders?

Anyone can develop an eating disorder, but they are more common in women. Eating disorders frequently appear during the teen years or young adulthood. But people can also develop them during childhood or later in life.

What are the symptoms of eating disorders?

The symptoms of eating disorders vary, depending on the disorder:

The symptoms of binge-eating include

• Eating unusually large amounts of food in a specific amount of time, such as a 2-hour period
• Eating even when you're full or not hungry
• Eating fast during binge episodes
• Eating until you're uncomfortably full
• Eating alone or in secret to avoid embarrassment
• Feeling distressed, ashamed, or guilty about your eating
• Frequently dieting, possibly without weight loss

The symptoms of bulimia nervosa include the same symptoms as binge-eating, plus trying to get rid of the food or weight after binging by

• Purging, making yourself throw up or using laxatives or enemas to speed up the movement of food through your body
• Doing intensive and excessive exercise
• Fasting

Over time, bulimia nervosa can cause health problems such as

• Chronically inflamed and sore throat
• Swollen salivary glands in the neck and jaw area
• Worn tooth enamel and increasingly sensitive and decaying teeth. This is caused by the exposure to stomach acid every time you throw up.
• GERD (acid reflux) and other gastrointestinal problems
• Severe dehydration from purging
• Electrolyte imbalance, which could be too low or too high levels of sodium, calcium, potassium and other minerals. This can lead to a stroke or heart attack.

The symptoms of anorexia nervosa include

• Eating very little, to the point of starving yourself
• Intensive and excessive exercise
• Extreme thinness
• Intense fear of gaining weight
• Distorted body image - seeing yourself as overweight even when you are severely underweight

Over time, anorexia nervosa can cause health problems such as

• Thinning of the bones (osteopenia or osteoporosis)
• Mild anemia
• Muscle wasting and weakness
• Thin, brittle hair and nails
• Dry, blotchy, or yellowish skin
• Growth of fine hair all over the body
• Severe constipation
• Low blood pressure
• Slowed breathing and pulse
• Feeling cold all the time because of a drop in internal body temperature
• Feeling faint, dizzy, or weak
• Feeling tired all the time
• Infertility
• Damage to the structure and function of the heart
• Brain damage
• Multiorgan failure

Anorexia nervosa can be fatal. Some people with this disorder die of complications from starvation, and others die of suicide.

Some people with eating disorders may also have other mental disorders (such as depression or anxiety) or problems with substance use.

How is eating disorders diagnosed?

Because eating disorders can be so serious, it is important to seek help if you or a loved one thinks that you might have a problem. Your health care provider may use many tools to make a diagnosis:

• A medical history, which includes asking about your symptoms. It is important to be honest about your eating and exercise behaviors so your provider can help you.
• A physical exam
• Blood or urine tests to rule out other possible causes of your symptoms
• Other tests to see whether you have any other health problems caused by the eating disorder. These can include kidney function tests and an electrocardiogram (EKG or ECG).

What are the treatments for eating disorders?

Treatment plans for eating disorders are tailored to individual needs. You will likely have a team of providers helping you, including doctors, nutritionists, nurses, and therapists. The treatments may include

• Individual, group, and/or family psychotherapy. Individual therapy may include cognitive behavioral approaches, which help you to identify and change negative and unhelpful thoughts. It also helps you build coping skills and change behavioral patterns.
• Medical care and monitoring, including care for the complications that eating disorders can cause
• Nutrition counseling. Doctors, nurses, and counselors will help you eat healthy to reach and maintain a healthy weight.
• Medicines, such as antidepressants, antipsychotics, or mood stabilizers, may help treat some eating disorders. The medicines can also help with the depression and anxiety symptoms that often go along with eating disorders.

Some people with serious eating disorders may need to be in a hospital or in a residential treatment program. Residential treatment programs combine housing and treatment services.

Epilepsy is a brain disorder that causes people to have recurring seizures. The seizures happen when clusters of nerve cells, or neurons, in the brain send out the wrong signals. People may have strange sensations and emotions or behave strangely. They may have violent muscle spasms or lose consciousness.

Epilepsy has many possible causes, including illness, brain injury, and abnormal brain development. In many cases, the cause is unknown.

Doctors use brain scans and other tests to diagnose epilepsy. It is important to start treatment right away. There is no cure for epilepsy, but medicines can control seizures for most people. When medicines are not working well, surgery or implanted devices such as vagus nerve stimulators may help. Special diets can help some children with epilepsy.

Seizures are symptoms of a brain problem. They happen because of sudden, abnormal electrical activity in the brain. When people think of seizures, they often think of convulsions in which a person's body shakes rapidly and uncontrollably. Not all seizures cause convulsions. There are many types of seizures and some have mild symptoms. Seizures fall into two main groups. Focal seizures, also called partial seizures, happen in just one part of the brain. Generalized seizures are a result of abnormal activity on both sides of the brain.

Most seizures last from 30 seconds to 2 minutes and do not cause lasting harm. However, it is a medical emergency if seizures last longer than 5 minutes or if a person has many seizures and does not wake up between them. Seizures can have many causes, including medicines, high fevers, head injuries and certain diseases. People who have recurring seizures due to a brain disorder have epilepsy.

What are migraines?

Migraines are a recurring type of headache. They cause moderate to severe pain that is throbbing or pulsing. The pain is often on one side of your head. You may also have other symptoms, such as nausea and weakness. You may be sensitive to light and sound.

What causes migraines?

Researchers believe that migraine has a genetic cause. There are also a number of factors that can trigger a migraine. These factors vary from person to person, and they include

• Stress
• Anxiety
• Hormonal changes in women
• Bright or flashing lights
• Loud noises
• Strong smells
• Medicines
• Too much or not enough sleep
• Sudden changes in weather or environment
• Overexertion (too much physical activity)
• Tobacco
• Caffeine or caffeine withdrawal
• Skipped meals
• Medication overuse (taking medicine for migraines too often)

Some people have found that certain foods or ingredients can trigger headaches, especially when they are combined with other triggers. These foods and ingredients include

• Alcohol
• Chocolate
• Aged cheeses
• Monosodium glutamate (MSG)
• Some fruits and nuts
• Fermented or pickled goods
• Yeast
• Cured or processed meats

Who is at risk for migraines?

About 12 percent of Americans get migraines. They can affect anyone, but you are more likely to have them if you

• Are a woman. Women are three times more likely than men to get migraines.
• Have a family history of migraines. Most people with migraines have family members who have migraines.
• Have other medical conditions, such as depression, anxiety, bipolar disorder, sleep disorders, and epilepsy.

What are the symptoms of migraines?

There are four different phases of migraines. You may not always go through every phase each time you have a migraine.

• Prodome. This phase starts up to 24 hours before you get the migraine. You have early signs and symptoms, such as food cravings, unexplained mood changes, uncontrollable yawning, fluid retention, and increased urination.
• Aura. If you have this phase, you might see flashing or bright lights or zig-zag lines. You may have muscle weakness or feel like you are being touched or grabbed. An aura can happen just before or during a migraine.
• Headache. A migraine usually starts gradually and then becomes more severe. It typically causes throbbing or pulsing pain, which is often on one side of your head. But sometimes you can have a migraine without a headache. Other migraine symptoms may include
  • Increased sensitivity to light, noise, and odors
  • Nausea and vomiting
  • Worsened pain when you move, cough, or sneeze
• Postdrome (following the headache). You may feel exhausted, weak, and confused after a migraine. This can last up to a day.

Migraines are more common in the morning; people often wake up with them. Some people have migraines at predictable times, such as before menstruation or on weekends following a stressful week of work.

How are migraines diagnosed?

To make a diagnosis, your health care provider will

• Take your medical history
• Ask about your symptoms
• Do a physical and neurological exam

An important part of diagnosing migraines is to rule out other medical conditions which could be causing the symptoms. So you may also have blood tests, an MRI or CT scan, or other tests.

How are migraines treated?

There is no cure for migraines. Treatment focuses on relieving symptoms and preventing additional attacks.

There are different types of medicines to relieve symptoms. They include triptan drugs, ergotamine drugs, and pain relievers. The sooner you take the medicine, the more effective it is.

There are also other things you can do to feel better:

• Resting with your eyes closed in a quiet, darkened room
• Placing a cool cloth or ice pack on your forehead
• Drinking fluids

There are some lifestyle changes you can make to prevent migraines:

• Stress management strategies, such as exercise, relaxation techniques, and biofeedback, may reduce the number and severity of migraines. Biofeedback uses electronic devices to teach you to control certain body functions, such as your heartbeat, blood pressure, and muscle tension.
• Make a log of what seems to trigger your migraines. You can learn what you need to avoid, such as certain foods and medicines. It also help you figure out what you should do, such as establishing a consistent sleep schedule and eating regular meals.
• Hormone therapy may help some women whose migraines seem to be linked to their menstrual cycle
• If you have obesity, losing weight may also be helpful

If you have frequent or severe migraines, you may need to take medicines to prevent further attacks. Talk with your health care provider about which drug would be right for you.

Certain natural treatments, such as riboflavin (vitamin B2) and coenzyme Q10, may help prevent migraines. If your magnesium level is low, you can try taking magnesium. There is also an herb, butterbur, which some people take to prevent migraines. But butterbur may not be safe for long-term use. Always check with your health care provider before taking any supplements.

Obesity means having too much body fat. It is different from being overweight, which means weighing too much. The weight may come from muscle, bone, fat, and/or body water. Both terms mean that a person's weight is greater than what's considered healthy for his or her height.

Obesity happens over time when you eat more calories than you use. The balance between calories-in and calories-out differs for each person. Factors that might affect your weight include your genetic makeup, overeating, eating high-fat foods, and not being physically active.

Obesity increases your risk of diabetes, heart disease, stroke, arthritis, and some cancers. If you have obesity, losing even 5 to 10 percent of your weight can delay or prevent some of these diseases. For example, that means losing 10 to 20 pounds if you weigh 200 pounds.

Your thyroid is a butterfly-shaped gland in your neck, just above your collarbone. It is one of your endocrine glands, which make hormones. Thyroid hormones control the rate of many activities in your body. These include how fast you burn calories and how fast your heart beats. All of these activities are your body's metabolism.

Thyroid problems include

• Goiter - enlargement of the thyroid gland
• Hyperthyroidism - when your thyroid gland makes more thyroid hormones than your body needs
• Hypothyroidism - when your thyroid gland does not make enough thyroid hormones
• Thyroid cancer
• Thyroid nodules - lumps in the thyroid gland
• Thyroiditis - swelling of the thyroid

To diagnose thyroid diseases, doctors use a medical history, physical exam, and thyroid tests. They sometimes also use a biopsy. Treatment depends on the problem, but may include medicines, radioiodine therapy, or thyroid surgery.

Uterine fibroids are the most common benign tumors in women of childbearing age. Fibroids are made of muscle cells and other tissues that grow in and around the wall of the uterus, or womb. The cause of fibroids is unknown. Risk factors include being African American or being overweight.

Many women with fibroids have no symptoms. If you do have symptoms, they may include

• Heavy or painful periods or bleeding between periods
• Feeling "full" in the lower abdomen
• Urinating often
• Pain during sex
• Lower back pain
• Reproductive problems, such as infertility, multiple miscarriages or early labor

Your health care provider may find fibroids during a gynecological exam or by using imaging tests. Treatment includes drugs that can slow or stop their growth, or surgery. If you have no symptoms, you may not even need treatment. Many women with fibroids can get pregnant naturally. For those who cannot, infertility treatments may help.

Sometimes pregnancy problems arise — even in healthy women. Some prenatal tests done during pregnancy can help prevent these problems or spot them early. Use this chart to learn about some common pregnancy complications. Call your doctor if you have any of the symptoms on this chart. If a problem is found, make sure to follow your doctor's advice about treatment. Doing so will boost your chances of having a safe delivery and a strong, healthy baby.

During pregnancy, your baby is protected from many illnesses, like the common cold or a passing stomach bug. But some infections can be harmful to your pregnancy, your baby, or both. This chart provides an overview of infections that can be harmful during pregnancy. Learn the symptoms and what you can do to keep healthy. Easy steps, such as hand washing, practicing safe sex, and avoiding certain foods, can help protect you from some infections.

Although every pregnancy has some risk of problems, continuing a pregnancy and delivering a baby is usually a safe, healthy process. Based on data from the CDC, the risk of dying as a direct result of pregnancy and childbirth is less than 10 in 100,000 live births. At 22 in 100,000, the risk is higher for African-Americans.

One out of 8,475 women dies from pregnancy complications. The most common causes of death for pregnant women are:

• Emboli (blood clots affecting the heart and brain);
• Eclampsia (high blood pressure complications affecting pregnancy);
• Heavy bleeding (Hemorrhaging);
• Sepsis (severe infection);
• Cerebral vascular accidents (stroke, bleeding in the brain); and
• Anesthesia-related deaths.

Altogether, these causes account for 80 percent of all deaths relating to a woman’s pregnancy. Unknown or uncommon causes account for the remaining 20 percent of deaths related to pregnancy. Women who have chronic severe diseases are at greater risk of death than healthy women.

Continuing your pregnancy also includes a risk of experiencing complications that are not always life-threatening.

• Approximately 15 to 20 of every 100 pregnant women require Caesarean delivery (C-section).
• One in 10 women may develop infection during or after delivery.
• About one in 20 pregnant women has blood pressure problems.
• One in 20 women suffer from excessive blood loss at delivery.

Labor is when a pregnant woman’s uterus contracts and pushes or delivers the baby from her body. The baby may be delivered through the woman’s vagina or by cesarean section. A Cesarean section is a surgical procedure.

The following are possible side effects and risks associated with vaginal delivery:

• Injury to the bladder or rectum;
• A hole (fistula) between the bladder and vagina or the rectum and vagina;
• Heavy bleeding (hemorrhaging);
• Inability to get pregnant in the future due to infection or complication from an operation;
• Emergency treatment for any of the above problems, including the possible need to treat with an operation, medicines or blood transfusion; and
• Rarely, death.

The following are possible side effects and risks associated with Cesarean delivery (C-section):

• Injury to the bowel or bladder;
• Inability to get pregnant in the future due to infection or complication from an operation;
• Heavy bleeding (hemorrhaging);
• Injury to the tube (ureter) between the kidney and bladder;
• A possible hysterectomy as a result of complication or injury during the procedure;
• Complications from anesthesia such as respiratory problems, headaches or drug reactions;
• Emergency treatment for any of the above problems, including the possible need to treat with an operation, medicines or a blood transfusion; and
• Rarely, death.

Emotional Reactions

After the birth of a baby, women often feel a number of powerful emotions. Many new moms experience baby blues following childbirth, which commonly include mood swings and crying spells. Typically, the symptoms of baby blues fade quickly, within a few days or weeks. Most women find that the best treatment for baby blue is reassurance, support from family and friends, rest and time.

Some new moms experience a more severe, long-lasting form of depression known as postpartum depression. At first, postpartum depression may feel a lot like baby blues, but eventually it interferes with a mother’s ability to care for her baby and handle other daily tasks. The Mayo Clinic recommends calling your doctor if the signs and symptoms of depression:

• Don’t fade after two weeks;
• Are getting worse;
• Make it hard for you to care for your baby;
• Make it hard to complete everyday tasks; and/or
• Include thoughts of harming yourself or your baby.
