What Is Bulimia? Signs and Symptoms

Bulimia Nervosa is an eating disorder characterised by, bingeing, eating large quantities of food in a short period of time, and then purging, engaging in over compensatory behaviours in order to counter-balance the effect on weight from the over eating.

Purging includes a range of behaviours including: periods of fasting, or severe calorie restriction; self-induced vomiting; laxative abuse and over exercising. All of these behaviours have the goal of purging the body of the unwanted food and calories to avoid weight gain. A sufferer does no need to engage in all of the purging behaviours in order to be suffering from Bulimia.
