Anorexia nervosa
An individual who has anorexia nervosa will show signs of avoiding or restricting food. They may even eat extremely small portions or certain foods only. It is common for an individual to see themselves as overweight, despite being underweight.
Anorexia is the least common eating disorder out of the three, but it’s typically the most dangerous. This condition has the highest death rate out of any mental health disorder.
Bulimia nervosa
Bulimia nervosa is when an individual experiences periods of binge-eating, that is followed by throwing up. They may even use laxatives, over-exercise, or fast after they purge. An individual who suffers from bulimia nervosa may be slightly underweight, a normal weight, or overweight. It is common for people with bulimia nervosa to also have anorexia nervosa.
Binge-Eating Disorder
An individual with a binge-eating disorder will continue to eat even after they are full. In fact, they may eat until they feel extremely uncomfortable. After purging, they may feel feelings of guilt, shame, and worry.
Unlike bulimia nervosa, they do not throw up, over-exercise, or take laxatives afterward. Binge eating disorder often leads to weight gain or obesity, and is the most common eating disorder in the U.S.
