Explanation of Bulimia Nervosa
Someone with bulimia nervosa typically eats large quantities of food followed by purging to rid their bodies of the calories and fare they have eaten. A person with bulimia may also use diuretics, laxatives and/or enemas as a way to purge the calories and/or food. Bulimics are secretive about their eating habits and often feel shame and disgust while they are binging on food. A bulimic may also feel a sense of relief and emotions will become more positive after purging.
