Can someone have an eating disorder without being underweight?

Yes. In fact, most people who suffer from eating disorders are not underweight. Some may meet all of the diagnostic criteria for anorexia besides a body weight that is 15% below ideal; and yet, the psychological and behavioral components to the disease still desperately need treatment. Many people with bulimia are at a normal or above-normal weight, as their body is able to glean a portion of the nutrition in the process of binging and purging. In addition, many people with binge eating disorder (BED) or other specified feeding or eating disorder (OSFED) suffer in silence. A person who binge eats may counter their binges by going days without a proper meal, and thus maintain a normal weight.
