Introduction: Diuretics and laxative abuse as a means of purging is common in patients with bulimia nervosa and there may be an underestimation of the true prevalence of diuretic abuse, as some are also available without prescription.
Case presentation: A 28-year-old woman presented with tetany due to hypocalcemia, hypokalemia and hypomagnesemia. She had a history of laxative and diuretic abuse, and salt craving. Psychiatric evaluation revealed a disturbed social history with masked depression that necessitated treatment.
Conclusions: Multiple prescription drug abuse and salt/salty food addiction usually reflects a personality of addiction, which leads to harmful use and dependence.
