User:Mr. Ibrahem/Cannabinoid hyperemesis syndrome

Cannabinoid hyperemesis syndrome (CHS) is recurrent nausea, vomiting, and cramping abdominal pain due to cannabis use. These symptoms may improve temporarily by taking a hot shower or bath. Complications may include kidney failure, electrolyte problems, and skin burns from hot water. At least two deaths have been associated with CHS.

Daily or weekly cannabis use for several years is generally required for the syndrome to occur. The underlying mechanism is unclear, with several possibilities proposed. Diagnosis is based on the symptoms. The condition is typically present for some time before the diagnosis is made. Another condition that may present similarly is cyclic vomiting syndrome.

Definitive treatment involves stopping use of cannabis. Up to two weeks may be required to see a benefit. Treatments during an episode of vomiting is generally supportive in nature. There is tentative evidence for the use of capsaicin cream on the abdomen and haloperidol during an acute episode.

The number of people affected is unclear. Of those who go to the emergency department in the United States with recurrent vomiting, about 6% have the condition. While legalization did not affect the rates, commercialization of cannabis results in an increase. The syndrome was first described in 2004, and simplified diagnostic criteria published in 2009.
