Anorexia Nervosa: An eating disorder characterized by an intense fear of gaining weight and a distorted body image which leads to self-imposed starvation and excessive weight loss.
Bulimia Nervosa: This is another type of eating disorder characterized by episodes of binge eating followed by compensatory behaviors such as vomiting (purging), fasting, or over-exercising.
Binge-Eating Disorder: This disorder involves regular episodes of extreme overeating and feelings of loss of control about eating, but unlike bulimia nervosa, periods of binge-eating are not followed by purging, excessive exercise, or fasting.
