Imagine getting drunk without drinking a single drop of alcohol. Even for a moment, it sounds strange, doesn’t it? Yet hidden within the fascinating world of medicine is a real condition called auto-brewery syndrome, a disorder that causes the body to produce alcohol on its own.
Auto-brewery syndrome (ABS), also known as “gut fermentation syndrome” or, more strikingly, “the drunk without drinking disease,” occurs when the body begins to ferment consumed carbohydrates and produce endogenous (internally generated) ethanol. As a result, a person can become intoxicated as if they had consumed several alcoholic drinks despite having had no alcohol at all.
First described in the 1950s, this syndrome develops when certain fungi (such as Candida albicans) and bacteria living in the gut multiply uncontrollably. Feeding on carbohydrates, these microorganisms act like yeast, carrying out fermentation and producing ethanol. The result can be nausea, dizziness, behavioral changes, slurred speech, and even severe intoxication, sometimes leading to serious traffic accidents.
Auto-brewery syndrome can affect individuals of all ages, even children. However, diagnosing the condition is often challenging because its symptoms are frequently mistaken for alcohol abuse or a psychiatric disorder. In fact, many people with this syndrome have even been brought to court after being wrongly accused of drinking alcohol.
Diagnosis may require specialized laboratory testing and carefully monitored dietary challenges. Treatment usually involves antifungal medications, probiotics, and a low-carbohydrate diet. In addition, stress, antibiotic use, and other factors that disrupt the balance of the gut microbiota should be carefully managed.
Auto-brewery syndrome is like a window into the microbiota universe that medicine is still striving to understand. We already know that our intestines influence not only digestion but also our mood, immune system, and many other aspects of health. This syndrome reminds us of one important truth: our gut is not only our second brain, but perhaps also the most mysterious laboratory within us.
Perhaps intoxication begins not only in the glass, but also in the gut.
