Anorexia nervosa. People with anorexia nervosa have a distorted perception of their body size and shape and may be very afraid of gaining weight or getting fat. They eat very little and often become extremely thin. But even when they become very thin, they may deny how serious their weight loss is or still believe they are overweight and may continue trying to lose weight. Some people with anorexia make themselves vomit. Females may stop (or never start) having menstrual periods. Complications, such as anemia or irregular heartbeats, may also develop.
Bulimia nervosa. People who have bulimia nervosa are overly concerned or worried about their body shape and weight. They also feel out of control of their eating and have binge eating episodes. To try to prevent weight gain, people with bulimia nervosa use "purging"-self-induced vomiting, laxatives or water pills, or excessive exercise-after a binge eating episode.
