- Nutrition therapy. Doctors, nurses, and counselors will help you eat healthy to reach and maintain a healthy weight. Some girls or women may need to be hospitalized or participate in a residential treatment program (live temporarily at a medical facility) to make sure they eat enough to recover. Hospitalization may also be required to monitor any heart problems in people with anorexia. Reaching a healthy weight is a key part of the recovery process so that your body's biology, including thoughts and feelings in your brain, work correctly.
- Psychotherapy. Sometimes called "talk therapy," psychotherapy is counseling to help you change any harmful thoughts or behaviors. This therapy may focus on the importance of talking about your feelings and how they affect what you do. You may work one-on-one with a therapist or in a group with others who have anorexia. For girls with anorexia, counseling may involve the whole family.
- Support groups can be helpful for some people with anorexia when added to other treatment. In support groups, girls or women and sometimes their families meet and share their stories.
- Medicine. Studies suggest that medicines like antidepressants can help some girls and women with anorexia by improving the depression and anxiety symptoms that often go along with anorexia.
- Miscarriage (pregnancy loss)
- Premature birth (also called preterm birth), or childbirth before 37 weeks of pregnancy

Anorexia nervosa, often called anorexia, is a type of eating disorder. People with anorexia eat so little that they have unhealthy weight loss and become dangerously thin. They may think they are overweight or fat even when they are underweight or thin. Anorexia affects more girls and women than boys and men. Anorexia is a serious health problem that can increase the risk of early death. But people with anorexia can get better with treatment.Expand all|Collapse all
What is anorexia?
Anorexia nervosa, often called anorexia, is a type of eating disorder. Eating disorders are mental health problems that cause extreme and dangerous eating behaviors. These extreme eating behaviors cause other serious health problems and sometimes death. Some eating disorders also involve extreme exercise.
Women with anorexia severely limit the amount of food they eat to prevent weight gain. People with anorexia usually have an intense fear of gaining weight and may think they are fat even when they are thin. Women with anorexia may also exercise too much so that they do not gain weight. Over time, eating so little food leads to serious health problems and sometimes death.
What is the difference between anorexia and other eating disorders?
Women with eating disorders, such as anorexia, bulimia, and binge eating disorder, have a mental health condition that affects how they eat, and sometimes how they exercise. These eating disorders threaten their health.
Unlike women with bulimia and binge eating disorder, girls and women with anorexia do not eat enough to sustain basic bodily functions. Women with bulimia and binge eating disorder usually binge, or eat too much while feeling out of control.
It is possible to have more than one eating disorder in your lifetime. Regardless of what type of eating disorder you may have, you can get better with treatment.
Who is at risk for anorexia?
Anorexia is more common among girls and women than boys and men.1
Anorexia is also more common among girls and younger women than older women. On average, girls develop anorexia at 16 or 17.2 Teen girls between 13 and 19 and young women in their early 20s are most at risk. But eating disorders are happening more often in older women. In one recent study, 13% of American women over 50 had signs of an eating disorder.3
What are the symptoms of anorexia?
Anorexia causes physical and psychological changes. A girl or woman with anorexia often looks very thin and may not act like herself.
Some other symptoms of anorexia include:
Girls or women with anorexia may also have behavior changes such as:
People with anorexia may also have other health problems, including depression, anxiety, or substance abuse.
What causes anorexia?
Researchers are not sure exactly what causes anorexia and other eating disorders. Researchers think that eating disorders might happen because of a combination of a person’s biology and life events. This combination includes having specific genes, a person’s biology, body image and self-esteem, social experiences, family health history, and sometimes other mental health illnesses.
Researchers are also studying unusual activity in the brain, such as changing levels of serotonin or other chemicals, to see how it may affect eating. Learn more about current research on anorexia.
How does anorexia affect a woman’s health?
With anorexia, your body doesn’t get the energy that it needs from food, so it slows down and stops working normally. Over time, anorexia can affect your body in the following ways:4
Anorexia is a serious illness that can also lead to death. Studies have found that more women and girls die from anorexia than any other eating disorder or serious mental health problem such as depression.6 Many people with anorexia also have other mental health problems such as depression or anxiety.7,8
Long-term studies of 20 years or more show that women who had an eating disorder in the past usually reach and maintain a healthy weight after treatment.9
How is anorexia diagnosed?
Your doctor or nurse will ask you questions about your symptoms and medical history. It may be difficult to talk to a doctor or nurse about secret eating or exercise behaviors. But doctors and nurses want to help you be healthy. Being honest about your eating and exercise behaviors with a doctor or nurse is a good way to ask for help.
Your doctor will do a physical exam and other tests, such as blood tests and a urine test, to rule out other health problems that may cause severe weight loss.
Your doctor may also do other tests, such as kidney function tests, bone density tests, or an electrocardiogram (ECG or EKG), to see if or how severe weight loss has affected your health.
How is anorexia treated?
Your doctor may refer you to a team of doctors, nutritionists, and therapists who will work to help you get better. If you live with family members they may be invited to participate in some of your treatment.
Treatment plans may include one or more of the following:
Most girls and women do get better with treatment and are able to eat and exercise in healthy ways again.10 Some may get better after the first treatment. Others get well but may relapse and need treatment again.
How does anorexia affect pregnancy?
Anorexia can cause problems getting pregnant and during pregnancy.
Extreme weight loss can cause missed menstrual periods because you may not ovulate, or release an egg from the ovary. When you do not weigh enough to ovulate, it is difficult to get pregnant. However, if you do not want to have children right now and you have sex, you should use birth control.
Anorexia can also cause problems during pregnancy. Anorexia raises your risk for:
If I had an eating disorder in the past, can I still get pregnant?
Yes. Women who have recovered from anorexia, are at a healthy weight, and have normal menstrual cycles have a better chance of getting pregnant and having a safe and healthy pregnancy.
If you had an eating disorder in the past, it may take you a little longer to get pregnant (about six months to a year) compared to women who never had an eating disorder.11
Tell your doctor if you had an eating disorder in the past and are trying to become pregnant.
If I take medicine to treat anorexia, can I breastfeed my baby?
Maybe. Some medicines used to treat anorexia can pass through breastmilk. Certain antidepressants can be used safely during breastfeeding.
Talk to your doctor to find out which medicine works best for you. Learn more about medicines and breastfeeding in our Breastfeeding section. You can also enter a medicine into the LactMed® database to find out if the medicine passes through breastmilk and about any possible side effects for your nursing baby.
