Bulimia Nervosa
Bulimia nervosa, commonly known as bulimia, is an eating disorder. It is a psychological condition in which the subject engages in recurrent binge eating followed by intentional purging. This purging is done in order to compensate for the excessive intake of food, usually to prevent weight gain. Purging can take the form of vomiting; inappropriate use of laxatives, enemas, diuretics or other medication; or excessive physical exercise. The word bulimia comes from the Latin (būlīmia) from the Greek βουλῑμια (boulīmia), ravenous hunger, compounded from βους (bous), ox + λῑμος (līmos), hunger.
