ACG Case Rep J. 2019 Sep 9;6(9):e00208. doi: 10.14309/crj.0000000000000208. eCollection 2019 Sep.


Information on auto-brewery syndrome is limited in the medical literature. This rare syndrome occurs when yeast overgrowth leads to ethanol fermentation in the gut. We present a patient presenting with symptoms of alcohol intoxication with objective laboratory data of elevated blood ethanol levels without a history of alcohol consumption. We reviewed the literature and have discussed the current diagnostic and therapeutic options.
