Auto-Brewery Syndrome: Diagnosis and Treatment of This Little-Known Condition.

Auto-brewery syndrome (ABS), also known as gut fermentation syndrome, is an underdiagnosed condition caused by an over-colonization of fermenting organisms in the gastrointestinal tract. These organisms-yeasts and, more recently recognized, bacteria-ferment carbohydrates into alcohol. The result is intoxication when not drinking, which may be accompanied by safety issues and even legal ramifications. If a patient with ABS is not treated, there may be adverse physical, social, psychological, and quality-of-life consequences. This article describes ABS presentation, diagnosis, treatment, and follow-up and the nursing implications for the care of patients wherever they are encountered. Through evidence-based nursing practice, people affected by ABS can begin to heal their gastrointestinal system. Nurses can educate patients and help them manage medications, diet, and lifestyle choices.
