Acquitted of Drunk-Driving Charges

A Belgian man was cleared of drunk driving charges because of a rare condition called auto-brewery syndrome. This means his body made alcohol independently, like a tiny brewery inside him. This condition was first found in Japan almost 70 years ago.

The man's run-in with the law was unexpected; he faced arrest for suspected intoxication after eating carbs. But upon closer examination by the researchers, it was discovered that the high alcohol levels in his blood weren't from drinking. Instead, they were due to his auto-brewery syndrome.

Auto-brewery syndrome, a rare condition where the gut ferments carbohydrates into alcohol, is an exceptional rarity, documented in only around 20 cases globally.

This uncommon medical phenomenon underscores the intricacies of human physiology and emphasizes the necessity for medical comprehension in legal contexts.

After being pulled over by police, the 40-year-old man underwent a breathalyzer test, registering 0.91 milligrams of alcohol per liter. A month later, he faced another arrest with a reading of 0.71 milligrams.

Despite the charges, they were eventually dropped after the man demonstrated that he suffered from auto-brewery syndrome (ABS). His lawyer, Anse Ghesquiere, affirmed this diagnosis, emphasizing the widespread underestimation of ABS cases globally.

Understanding Auto-Brewery Syndrome

Auto-brewery syndrome, or gut fermentation syndrome, is a rare medical anomaly wherein the body produces ethanol, the alcohol found in beverages, internally. This occurs through fermentation processes catalyzed by fungi or bacteria in the gastrointestinal or urinary systems.

People suffering from auto-brewery syndrome commonly display symptoms resembling alcohol intoxication, such as coordination issues and speech difficulties. This occurrence is often linked to their dietary intake, particularly the consumption of sugars and carbohydrates. 

These nutrients act as a fuel source for microorganisms within the body, triggering ethanol production. As a result, even without consuming alcoholic beverages, individuals with this syndrome can exhibit signs of intoxication.

Although auto-brewery syndrome is commonly observed in individuals with pre-existing health issues like diabetes, obesity, and Crohn's disease, it can also occur in individuals without any underlying conditions.

Moreover, this syndrome has been identified in people of all ages and genders, including children.

Reportedly, treatment for auto-brewery syndrome encompasses various approaches such as regulating dietary carbohydrate intake, administering antifungal or antibiotic medications, avoiding general antibiotics, and incorporating probiotics. 

Following treatment, most patients can typically revert to their regular dietary habits and daily routines after undergoing just one round of therapy.

However, the condition can significantly impact both patients and their families, as it often leads to misconceptions regarding alcohol consumption, potentially resulting in social and legal ramifications.

The earliest documented cases of auto-brewery syndrome trace back to Japan in the 1950s, where it was initially observed.

Some theories suggested a predisposition among the Japanese population, possibly due to genetic factors resulting in a diminished capacity of the liver to metabolize ethanol.
