Auto-brewery syndrome, also known as gut fermentation syndrome, is a rare medical condition in which intoxicating quantities of ethanol are produced through endogenous fermentation within the digestive system. One gastrointestinal organism, Saccharomyces cerevisiae, a type of yeast, has been identified as a pathogen for this condition.
One case went undetected for 20 years.
A variant occurs in persons with liver abnormalities that prevent them from excreting or breaking down alcohol normally. Patients with this condition can develop symptoms of auto-brewery syndrome even when the gut yeast produces a quantity of alcohol that is too small to intoxicate a healthy individual.
The effects of the disease can have profound effects on everyday life. As well, the recurring side effects of excessive belching, dizziness, dry mouth, hangovers, disorientation, irritable bowel syndrome, and chronic fatigue syndrome can lead to other health problems such as depression, anxiety and poor productivity in employment. The random state of intoxication can lead to personal difficulties, and the relative obscurity of the condition can also make it hard to seek treatment.
