Cannabinoid Hyperemesis Syndrome During Pregnancy A Case Report

BACKGROUND: Cannabinoid hyperemesis syndrome (CHS) is a syndrome characterized by chronic marijuana use, cyclic vomiting, and compulsive bathing. Given the similarities this syndrome shares with hyperemesis gravidarum, it is likely that this is a highly underdiagnosed syndrome. We present a case of severe nausea and vomiting during pregnancy that met the criteria for CHS. CASE: This case outlines the course of recurrent nausea and vomiting due to cannabinoid hyperemesis in a pregnant patient and illustrates the similarities between hyperemesis gravidarum and CHS and the value of obtaining a complete history that includes the use of marijuana. CONCLUSION: Recognition of this syndrome will aid in patient care, lessen the economic burden of an extensive workup, and hopefully lessen provider frustration with diagnosis and treatment of a common and under diagnosed entity.
