This is one heck of a weird story. A 61 year old man found himself getting drunk without even drinking because his gut was brewing yeast for him. Whenever he ate any carbs, his intestinal tract would start turning it into beer.
The patient had an infection with Saccharomyces cerevisiae, Cordell says. So when he ate or drank a bunch of starch — a bagel, pasta or even a soda — the yeast fermented the sugars into ethanol, and he would get drunk. Essentially, he was brewing beer in his own gut. Cordell and McCarthy reported the case of "auto-brewery syndrome" a few months ago in the International Journal of Clinical Medicine.
It's definitely an infection we don't want to have.
