Endogenous ethanol production, or auto-brewery syndrome (ABS), is a rare condition of the human alimentary canal that results in intoxication without alcohol consumption. Despite its clinical significance, ABS remains largely undiagnosed because of a lack of awareness among clinicians. Published cases have reported extensive biopsychosocial comorbidities accompanying delayed diagnosis and incomplete management; these include social rejection and family separation, court-ordered alcohol rehabilitation and psychiatric admission, legal and employment ramifications, and deteriorating mental health and suicidality. In this mini review, we aim to educate and enlighten clinicians by discussing literature findings pertaining to the pathophysiological mechanisms of gut dysbiosis due to overgrowth of Saccharomyces cerevisiae, E. coli and Klebsiella, impaired intestinal barrier function, and dysregulation of the hypothalamic-pituitary-adrenal axis. Furthermore, we discuss recently discovered associations with sleep quality and mood disorders and explore the medical sequelae of metabolic dysfunction-associated fatty liver disease and metabolic dysfunction-associated steatohepatitis. Drawing on these data, we propose protocols for initial care in the emergency room, subsequent critical care, diagnostic testing with glucose challenge testing, and definitive microbiological testing during the acute phase of illness. We also present an empirical treatment outline while awaiting confirmation of causative organisms and sensitivities.
