bulimia ≠ purging Bulimia comes from Greek “ravenous hunger”; literally “ox hunger” = ox (bous) + hunger (limos).

+5/- drdoom(1206)

N.B., there are many ways to “purge”; the method of purge determines the observed electrolyte disturbance. A nice description of bulimia nervosa from MeSH:

BULIMIA NERVOSA. An eating disorder that is characterized by a cycle of binge eating (BULIMIA or bingeing) followed by inappropriate acts (purging) to avert weight gain. Purging methods often include self-induced VOMITING, use of LAXATIVES or DIURETICS, excessive exercise, and FASTING.
