Bulimia Nervosa in Children

Medically reviewed by Last updated on Aug 31, 2022.

What is bulimia nervosa?

Bulimia nervosa is an eating disorder. Your child eats a large amount of food in a short period of time. This is called binging. She or he then vomits, uses laxatives, starves, or exercises for hours to prevent weight gain. This is called purging. Your child does this at least 1 time each week for several months.

What increases my child's risk for bulimia nervosa?

Bulimia is more common in girls, and in adolescents. The following may increase your child's risk:

  • Being overweight or thinking she or he is too heavy
  • Not feeling good about her or his body
  • A need to be perfect, or setting high goals
  • Participation in a sport or activity that values thinness, such as gymnastics, wrestling, or modeling
  • A history of anxiety, depression, or obsessive-compulsive thoughts
  • A family history of an eating disorder, obesity, or problems with substance abuse
  • Not having good relationships with family members, or stress or trauma

What are the signs and symptoms of bulimia nervosa?

  • Not being able to stop eating, usually secretly or when she or he is alone
  • Spending a long time in the bathroom, especially with water running to cover the sound of vomiting
  • Saying she or he is fat even if her or his weight is healthy or too low, or weight that goes up and down often
  • Often being bloated and having constipation or diarrhea
  • A sore throat and tooth decay caused by vomiting
  • A puffy face and throat, dehydration, or thinning hair
  • Calluses or cuts on your child's knuckles if she or he uses her or his hand to make herself or himself vomit
  • In adolescent girls, monthly periods that are irregular or stop completely
  • Feeling cold all the time, or tired, weak, dizzy, or lightheaded
  • Being moody and depressed, believing self-worth is tied to weight, or talking about food and weight all the time

How is bulimia nervosa diagnosed?

Your child's healthcare provider will examine him or her and check his or her height and weight. The provider may ask you and your child to fill out forms about his or her eating habits. Your child may have a hard time talking about his or her weight or about bingeing and purging. Your child may also have trouble asking for help. The provider may recommend an eating disorder expert who specializes in working with children or adolescents. The following tests can help your provider understand how bulimia may be affecting your child's body:

  • Blood tests will show if your child is getting enough iron, calcium, and other nutrients.
  • Urine tests may be used to check for signs of dehydration.
  • Bone density pictures may show bone loss that bulimia can cause. Your child's risk for bone loss is higher if she is female and no longer has a monthly period.

  • An EKG may be used to check the electrical activity of your child's heart. Bulimia can lead to heart rhythm problems.

How is bulimia nervosa treated?

Bulimia is a life-threatening medical condition. Treatment may need to take place in a hospital or clinic. Treatment will be more effective if your child understands the seriousness of the condition and truly wants to get better.

  • Counseling is an important part of treatment. Your child may work with healthcare providers alone or in a group. Group counseling is a way for your child to talk with others who have bulimia. Counseling may center on helping your child replace negative thoughts with positive thoughts. Family sessions can help everyone in the family understand bulimia and what to do to help your child.
  • Nutrition therapy means you and your child will meet with a dietitian. Together you will develop a healthy meal plan. It is important for your child to eat 3 to 5 structured meals a day to reduce the urge to binge. Your child might need to learn how to prepare healthy food. She or he might also need to relearn what it feels like to be hungry and full. You or your child may be asked to keep a food diary and bring it to future visits.
  • Medicines are sometimes used to help treat bulimia or the health problems it causes. Your child may get medicine to help improve mood, control mood swings, and decrease obsessive thoughts or irritability. Vitamin or mineral supplements may also be needed if your child's nutrient levels are low because of bulimia.

What can I do to help my child?

  • Be patient and supportive. Recovery from bulimia is a process that takes time. Your child may have a binging and purging episode after a long period of healthy eating. This is common. Help your child get back on track with healthy eating and healthy exercise. Do not punish your child for the episode. Be available if your child wants to talk about her or his feelings.
  • Help your child develop healthy self-esteem. Your child's self-esteem may be tied to her or his weight or appearance. Ask your child what she or he likes about herself or himself. For example, your child may be a talented artist, or may write well. Encourage your child to focus on those skills or talents instead of on appearance. Do not comment on your child's weight or shape. Your child's healthcare provider can tell you healthy weight ranges for your child.
  • Have regular family meals. Your child may be able to help you plan and cook meals. At mealtime, do not focus on your child's choices. For example, do not tell your child to take a larger portion or to go for another helping. Do not criticize your child's choices. It may take time before your child is ready to eat like others at the table.
    Diverse Family Eating Together
  • Set a healthy example. Let your child see you eat healthy foods in correct portions. Do not tell your child you are on a diet or say that you need to lose weight. Tell your child what you like about your own body and what you do to stay healthy.
  • Spend time doing things your child enjoys. Make family time about being together, not about meals. Try to go to places other than restaurants, movies, and other places that feature food.
