What Is Psychogenic Polydipsia?

Binge eating is common in bulimia nervosa (bulimia) and bulimia. Bulimia nervosa is a type of anorexia nervosa characterized by pathological fear of obesity and self-set weight standards that are significantly lower than normal health standards. It uses extreme measures to counteract after episodes of bulimia and overeating. Food-induced obesity is a major clinical manifestation of eating disorders. This symptom group contains two main components: one is irresistible forced multi-eating; the other is trying to vomit to avoid weight gain, and sometimes laxative abuse. The weight of such patients is usually kept within the normal range, and women's menstrual periods can still be normal. This disease is more common in women. Binge eating disorder refers to recurrent binge eating, but without compensatory actions such as vomiting to avoid weight gain.
