Abstract
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.
