A recent study (I Aziz et al. Clin Gastroenterol Hepatol 2019; 17: 878-86) examined the epidemiology and clinical characteristics of Rome IV functional nausea and vomiting disorders (FNVDs) in adults. The study used internet cross-sectional health surveys from 5931 adults in 2015.
- 2.2% of the population (n=131) fulfilled criteria for Rome IV FNVDs
- Hot water bathing, which has been reported in cannaboid hyperemesis syndrome, was also noted in patients with cyclic vomiting syndrome (CVS) in 44%. “This behavior was independent of cannabis but augmented by its use.”
My take: FNVDs are common and hot water bathing is not pathognomonic for cannaboid hyperemesis syndrome.
