Bulimia nervosa

Bulimia nervosa is an eating disorder characterized by binge eating and purging or consuming a large amount of food in a shortamount of time, followed by an attempt to rid oneself of the food consumed, usually by purging (vomiting) and/or by laxative, diuretics or excessive exercise.[1] [2] Bulimia nervosa is nine times morelikely to occur in women than men (Barker 2003). Antidepressants, especially SSRIs, are widely used in the treatment of bulimia nervosa. (Newell and Gournay 2000).
The term bulimia comes fromGreek βουλιμία (boulīmia; ravenous hunger), a compound of βους (bous), ox + λιμός (līmos), hunger.[3] Bulimia nervosa was named and first described by the British psychiatrist Gerald Russell in1979.[4][5] Bulimia is strongly familial. Twin studies estimate the heritability of syndromic bulimia to be 54 to 83%. [6][7]
