3 Apr
Summary
- The rare Auto-brewery syndrome causes the body to produce alcohol internally.
- Patients are often misdiagnosed with mental health conditions or alcoholism.
- Dietary changes and medication can help manage the condition effectively.

Auto-brewery syndrome, a rare condition where gut microbes overproduce ethanol from food, causes inexplicable intoxication. This can lead to severe life disruptions, including DUIs and damaged reputations, as seen in cases like Mark Mongiardo's. Patients are frequently misdiagnosed, with symptoms often mistaken for mental health issues or alcoholism.
Medical interest in Auto-brewery syndrome is growing, with ongoing research shedding light on its causes, which may involve bacterial or fungal overgrowth in the gut, potentially linked to antibiotic use. Diagnosis remains challenging, but doctors are becoming more adept at identifying the condition.
Treatment typically involves dietary modifications, such as reducing carbohydrate and sugar intake, and medications like antifungals or antibiotics and probiotics. While many patients achieve successful recovery, some require ongoing management or face potential alcohol withdrawal symptoms or cravings. Awareness and research are crucial for better diagnosis and support for those affected by this perplexing syndrome.
