What do people who suffer from bulimia engage in?

Bulimia nervosa is an eating disorder characterized by binge eating followed by purging. People who suffer from bulimia engage in a cycle of binge eating and purging in order to control their weight or body image. Binge eating is characterized by consuming large amounts of food in a short period of time, often until feeling uncomfortably full. Purging involves behaviors such as vomiting, using laxatives or diuretics, or excessive exercise in order to rid the body of the calories consumed during the binge. People with bulimia may also engage in other behaviors such as restricting their food intake, fasting, or excessive dieting.
