title: Cannabinoid hyperemesis syndrome masquerading as an eating disorder.
abstract: The case of a 22 year old woman with cannabinoid hyperemesis syndrome (CHS) presenting as an eating disorder is described. The importance of recognizing chronic cannabis use as a cause of episodic vomiting is emphasized, given that CHS can be confused with self-induced purging and cyclic vomiting. This case was further complicated by the well-defined history of anorexia nervosa (binge-purge type), major depressive disorder, obsessive-compulsive disorder, migraine headache, and the initial denial of cannabis use. However, collateral history and a positive drug screen confirmed the diagnosis. The signs, symptoms and pathophysiological mechanisms of CHS are reviewed in light of clinical presentations that mimic eating disorder phenomenology complicated by addiction. Given the trend for increasing legalization of recreational marijuana as well as medical marijuana, CHS is an important and potentially complicating disorder that eating disorder clinicians need to be aware of. © 2016 Wiley Periodicals, Inc.
