Bulimia nervosa: What it is, and how to help

What is bulimia?

Bulimia nervosa, often called simply bulimia, is a type of eating disorder. A person with bulimia eats a lot of food in a short amount of time (binging) and then tries to prevent weight gain by getting rid of the food (purging).

Purging might be done by:

  • Making yourself throw up
  • Taking laxatives (pills or liquids that speed up the movement of food through your body and lead to a bowel movement)

Unlike anorexia, people with bulimia can fall within the normal range for their age and weight.

But similar to people with anorexia, bulimics:

  • Fear gaining weight
  • Want desperately to lose weight
  • Are very unhappy with their body size and shape
Who becomes bulimic?

Many people think that eating disorders affect only young, upper-class white females. While it is true that most bulimics are women (around 85-90 percent), bulimia affects people from all walks of life, including males, women of color, and even older women.

It is not known for sure whether African American, Latina, Asian/Pacific Islander, and American Indian and Alaska Native people develop eating disorders because American culture values thin people. People with different cultural backgrounds may develop eating disorders because it’s hard to adapt to a new culture (a theory called “culture clash”). The stress of trying to live in two different cultures may cause some minorities to develop their eating disorders.

Jen’s story

It was ten years ago when I became bulimic. I had always worried about my weight and how I looked. I thought I looked fat, no matter what the scale showed or anyone said. But I had never made myself throw up — not until after college. I felt stressed out after graduating from college. I was very overwhelmed with my new job and turned to food to feel more in control of my life. Sometimes, I’d eat a lot of food and throw it up. Other times, I’d throw up a normal meal. At the time, it seemed like the only way I could cope with my stress. Luckily, I got help from a doctor, after a friend talked to me about the problem. It took a lot of work, but I am better now.

What causes bulimia?

Bulimia is more than just a problem with food. A binge can be triggered by dieting, stress, or uncomfortable emotions, such as anger or sadness. Purging and other actions to prevent weight gain are ways for people with bulimia to feel more in control of their lives and ease stress and anxiety. There is no single known cause of bulimia, but there are some factors that may play a part.

  • Culture. Women in the US are under constant pressure to fit a certain ideal of beauty. Seeing images of flawless, thin females everywhere makes it hard for women to feel good about their bodies.
  • Families. If you have a mother or sister with bulimia, you are more likely to also have bulimia. Parents who think looks are important, diet themselves, or criticize their children’s bodies are more likely to have a child with bulimia.
  • Life changes or stressful events. Traumatic events (like rape), as well as stressful things (like starting a new job), can lead to bulimia.
  • Personality traits. A person with bulimia may not like herself, hate the way she looks, or feel hopeless. She may be very moody, have problems expressing anger, or have a hard time controlling impulsive behaviors.
  • Biology. Genes, hormones, and chemicals in the brain may be factors in developing bulimia.

What are signs of bulimia?

A person with bulimia may be thin, overweight, or have a normal weight. Also, bulimic behavior, such as throwing up, is often done in private because the person with bulimia feels shame or disgust. This makes it hard to know if someone has bulimia. But there are warning signs to look out for. Someone with bulimia may use extreme measures to lose weight by:

  • Using diet pills, or taking pills to urinate or have a bowel movement
  • Going to the bathroom all the time after eating (to throw up)
  • Exercising a lot, even in bad weather or when hurt or tired

Someone with bulimia may show signs of throwing up, such as:

  • Swollen cheeks or jaw area
  • Calluses or scrapes on the knuckles (if using fingers to induce vomiting)
  • Teeth that look clear
  • Broken blood vessels in the eyes

People with bulimia often have other mental health conditions, including:

  • Depression
  • Anxiety
  • Substance abuse problems

Someone with bulimia may also have a distorted body image, shown by thinking she or he is fat, hating her or his body, and fearing weight gain.

Bulimia can also cause someone to not act like her or himself. She or he may be moody or sad, or may not want to go out with friends.

Can someone with bulimia get better?

Yes. Someone with bulimia can get better. A health care team of doctors, nutritionists, and therapists will help the patient recover. They will help the person learn healthy eating patterns and cope with their thoughts and feelings. Treatment for bulimia uses a combination of options. Whether or not the treatment works depends on the patient.

To stop a person from binging and purging, a doctor may recommend the patient:

  • Receive nutritional advice and psychotherapy, especially cognitive behavioral therapy (CBT)
  • Be prescribed medicine

CBT is a form of psychotherapy that focuses on the important role of thinking in how we feel and what we do. CBT that has been tailored to treat bulimia has shown to be effective in changing binging and purging behavior, and eating attitudes. Therapy for a person with bulimia may be one-on-one with a therapist or group-based.

Some antidepressants, such as fluoxetine (Prozac), which is the only medication approved by the US Food and Drug Administration (FDA) for treating bulimia, may help patients who also have depression and/or anxiety. It also appears to help reduce binge-eating and purging behavior, reduces the chance of relapse, and improves eating attitudes. (“Relapse” means to get sick again, after feeling well for a while.)

What should I do if I think someone I know has bulimia?

If someone you know is showing signs of bulimia, you may be able to help.

  1. Set a time to talk. Set aside a time to talk privately with your friend.  Make sure you talk in a quiet place where you won’t be distracted.
  2. Tell your friend about your concerns. Be honest. Tell your friend about your worries about his or her eating or exercising habits. Tell your friend you are concerned and that you think these things may be a sign of a problem that needs professional help.
  3. Ask your friend to talk to a professional. Your friend can talk to a counselor or doctor who knows about eating issues. Offer to help your friend find a counselor or doctor and make an appointment, and offer to go with him or her to the appointment.
  4. Avoid conflicts. If your friend won’t admit that he or she has a problem, don’t push. Be sure to tell your friend you are always there to listen if he or she wants to talk.
  5. Don’t place shame, blame, or guilt on your friend.  Don’t say, “You just need to eat.” Instead, say things like, “I’m concerned about you because you won’t eat breakfast or lunch.” Or, “It makes me afraid to hear you throwing up.”
  6. Don’t give simple solutions. Don’t say, “If you’d just stop, then things would be fine!”
  7. Let your friend know that you will always be there no matter what.
Is it safe for young people to take antidepressants for bulimia?

It may be safe for young people to be treated with antidepressants. However, drug companies who make antidepressants are required to post a “black box” warning label on the medication. A “black box” warning is the most serious type of warning on prescription medicines.

It may be possible that antidepressants make children, adolescents, and young adults more likely to think about suicide or commit suicide.

The FDA offers the latest information, including which drugs are included in this warning and danger signs to look for, on their website at fda.gov.
