5 Facts you should know about

Auto-brewery syndrome



A condition characterized by the fermentation of ingested carbohydrates

in the gastrointestinal tract of the body caused by bacteria or fungi.


Symptoms that usually accompany ABS include elevated blood alcohol levels

as well as symptoms consistent with alcohol intoxication—such as slurred speech, stumbling, loss of motor functions, dizziness, and belching.


Organisms use lactic acid fermentation

or mixed acid fermentation pathways to produce an ethanol end product.


The ethanol generated from these pathways is absorbed in the small intestine,

causing an increase in blood alcohol concentrations that produce the effects of intoxication without the consumption of alcohol.


Auto-brewery syndrome is more prevalent in patients with co-morbidities

such as diabetes, obesity, and Crohn’s disease.
