Anorexia is an eating disorder characterized by severe restraint in food intake and/or excess physical activity. It is often linked to negative feelings toward body image. Over time, anorexia can cause severe symptoms, such as stunted growth, bone loss, damage to major organs such as the heart, and even death.


The cause of anorexia in children is not known. It appears that genetics and environment play a role.

You will be asked about your child’s symptoms and medical history. A physical exam and a psychological evaluation will be done. The diagnosis will be based on information from you and your child and the examination.

If anorexia is suspected or diagnosed your child’s doctor may order further tests to determine what effect the anorexia has had on your child’s overall health. Tests may include:

  • Blood tests—to look for changes in electrolytes, vitamins, and other important nutrients.
  • Electrocardiogram (EKG)—to look for any effects on the heart.
  • Bone density test—to test the health of your child’s bones, especially in girls whose menstrual periods are absent.

Management of anorexia will include:

  • Addressing the feelings and distorted thoughts causing the condition.
  • Identifying and managing any physical problems caused by poor food intake.

The length and intensity of treatment will depend on the individual child. Regular supervision by health care specialist will help to make sure that hydration and nutrient levels have not dropped to dangerous levels during recovery. It may take many years to fully manage anorexia. Treatment often includes more than one approach but may include:

Nutritional Support

You may be referred to a dietitian who will talk to you and your child about practical weight goals and calorie goals. A dietitian will also assure proper weight gain and help your child develop good eating habits.

Severe malnutrition may require the delivery of nutrients through a tube that is passed through the nose and into the stomach.


Therapy can help address factors that may be linked to your child’s anorexia including harmful thought patterns, anxiety, and poor self-esteem. It can also help your child develop a more positive attitude about food and their body image.

Work with your child’s doctor and therapists to determine which therapy may be best for your child. Your child may use more than one type of therapy or try different therapies before the right one is found. Some therapy options include:

  • Family therapy—recovery is often more successful if family members take part in therapy. All family members need to understand the disorder to provide the proper support.
  • Cognitive behavioral therapy—to help your child develop a healthier and more realistic self-image. The therapist will help your child find new ways to think about his or her body and diet.
  • Interpersonal therapy—to help your child understand and cope with concerns about relationships

In some cases, a combination of psychotherapy and antidepressant medication may be used to help manage your child’s anorexia.


Hospitalization may be needed to provide critical nutrition or to monitor problems caused by the anorexia such as heart disorder.

An inpatient eating disorder program may help children who have not found success with outpatient programs.


There are no guidelines to prevent anorexia in children. Early detection and treatment is the best option.
