If you've never heard of it before, there's a very rare medical problem called "auto-brewery syndrome" in which a patient's guts somehow align a series of extremely improbable stars and start fermenting consumed carbs into alcohol. Such as in the intestines. Just... all on their own. Constantly.
"So the patient starts pooping alcohol?" Nope! It depends where it's located but it often ends up in the bloodstream. Doctors generally find out ABS is afoot when they notice a patient's BAC is up and/or they're displaying symptoms of being drunk 24/7 despite not imbibing.
It's very rare and treatment is amply available– just gotta nuke the fermenting microbe(s) and maybe cut down on carbs until you're fixed– but it's among the most "qhat?" rare health problems I've ever heard of. And now you've heard of it too!
