Dismissed for Nearly a Decade
For close to 10 years, Eric Poulin, a Nova Scotia man, experienced episodes where he appeared intoxicated — slurred speech, impaired coordination, the whole picture — despite not having consumed a single drop of alcohol. Instead of answers, he was repeatedly dismissed by people around him who assumed he was hiding a drinking problem.
His story, reported by CBC News, is finally getting the attention it deserves — and it's opening up a broader conversation about a condition that remains stubbornly under-diagnosed across Canada.
What Is Auto-Brewery Syndrome?
Auto-brewery syndrome, sometimes called gut fermentation syndrome, is a rare medical condition in which yeast or bacteria in the gastrointestinal tract ferments carbohydrates from food into ethanol — essentially producing alcohol inside the body. The result is that a person can register measurable blood alcohol levels and exhibit all the outward signs of intoxication without ever drinking.
The condition is real, documented in peer-reviewed medical literature, but it remains poorly understood and frustratingly difficult to diagnose. Because patients present as drunk, they are often met with scepticism — from family, employers, and even healthcare providers. Many, like Poulin, spend years cycling through disbelief and misdiagnosis before anyone takes them seriously.
The Burden of Not Being Believed
Being labelled an alcoholic when you're not carries significant social and psychological weight. For Poulin, nearly a decade passed while he quietly suffered through episodes that disrupted his daily life, all while carrying the stigma of a condition he didn't have.
This pattern — patient dismissed, patient disbelieved — is unfortunately common among people with rare diseases, particularly those whose symptoms are behavioural rather than visibly physical. Medical research consistently shows that patients with unusual presentations wait years longer for a correct diagnosis compared to those with more textbook conditions.
Auto-brewery syndrome sits squarely in that gap. Its symptoms mimic alcohol intoxication so precisely that even breathalyzer readings can appear elevated, making it nearly impossible for patients to defend themselves without a formal medical workup.
Getting to a Diagnosis
Diagnosis typically involves controlled observation — monitoring a patient's blood alcohol levels after a carbohydrate-rich meal, while confirming zero alcohol consumption. Stool and gut microbiome testing can also reveal overgrowths of yeast species like Saccharomyces cerevisiae or certain bacteria.
Treatment often combines antifungal or antibiotic medication with significant dietary changes, particularly reducing high-carb and sugary foods that feed the fermentation process. In many cases, restoring healthy gut flora — which can be disrupted by prolonged antibiotic use — is a key part of recovery.
A Reminder That Rare Doesn't Mean Impossible
Poulin's story is a reminder of why patient advocacy matters and why rare diseases deserve more mainstream medical attention. In Canada, rare disease awareness has grown in recent years, but access to specialists — particularly in smaller provinces — remains uneven.
For anyone who has ever been told their symptoms don't add up, or who has felt unheard by the medical system, stories like this one carry weight. Being believed is the first step toward getting better.
