Some teens have an extreme fear of being at a higher weight or having obesity. This leads them to stay away from food, eat very little, or eat very small amounts of only certain foods. They may even appear to starve themselves. They are often at a very low weight. But they see themselves as being at a very high weight. They also may weigh themselves repeatedly. Or exercise to the extreme. This condition is called anorexia nervosa.
Anorexia nervosa is a serious, complex problem involving social, behavioral, cultural, physical, and mental components. It's not a lifestyle choice. Though it is more often associated with females, it can affect males, too. Symptoms include severe weight loss, vomiting and diarrhea, and lack of energy. Also, hair thinning, amenorrhea (loss of menstruation), and other serious physical problems. If not treated, severe anorexia nervosa can be fatal.
It's hard to assess and care for children with anorexia. A complete physical and medical history is needed for a diagnosis. It's especially important to be alert when male teens have weight loss or other anorexia-related symptoms. Often the anorexia symptoms can be overlooked and males don't get appropriate care in a timely manner.
Severe malnutrition may need a hospital stay and I.V. (intravenous) or tube feedings. Doctors, nurses, dietitians, and psychologists will be part of your child's health care team. A dietitian will work with the family to make sure that a child gets healthy food and fluid intake and gains weight. A counselor and other mental health providers will help the family with conflicts and provide individual therapy to the child and family therapy. Full recovery often takes years.
