My friend says that he has an eating disorder. What is it?

Anorexia nervosa is a mental health condition where someone has an intense fear of gaining weight or becoming fat, and they may engage in behaviors to avoid this outcome. These behaviors can include fasting, excessive exercise, or self-induced vomiting. People with anorexia are at risk for serious medical complications, including heart problems, bone loss, and infections. It's important to seek help if you have concerns about your friend's eating habits.
