Bulimia is an eating disorder resulting from a mental illness - typically the fear of becoming obese, combined with poor impulse control and periods of binge eating followed by efforts to purge the body of the food eaten, whether by forced vomiting, laxative or enema abuse, or excessive exercise. Being a mental illness, it is not contagious, but there are some suggestions that it may be heritable, with twin studies showing up to 80% concordance for bulimia.
