Auto-Brewery Syndrome: Gut disorder causes internal alcohol production
Imagine your tummy turning into a tiny brewery!
That’s what happens with Auto-Brewery Syndrome (ABS).
Certain bugs in your gut can turn the food you eat, like carbs, into alcohol.
This makes you feel drunk even if you haven't had a drink.
People with ABS might slur their words, feel dizzy, or have trouble thinking clearly.
Doctors test for it by checking alcohol levels in the blood.
It can be tricky to figure out, and people sometimes get wrongly accused of drinking.
It’s important to eat healthy, avoid unnecessary antibiotics, and take care of your gut to keep this from happening.
Auto-Brewery Syndrome (ABS) causes the gut to produce alcohol from food.
The syndrome is triggered by yeast or bacteria that ferment carbs.
Symptoms include dizziness, brain fog, and slurred speech.
Diagnosis involves blood alcohol tests and possibly a glucose challenge.
ABS is often misdiagnosed and can negatively impact daily life.
