Is Auto-Brewery Syndrome the Reason for My DWI?


While auto-brewery syndrome does exist, it is a rare condition. Essentially, the syndrome is when an individual’s body ferments alcohol. This happens when yeast within a person’s gut produces ethanol. Then, a person who has auto-brewery syndrome can appear and feel drunk, without ever consuming an alcoholic beverage. They could even register as intoxicated on a test.

After a DWI arrest, you need to assess all of your options. Discuss your situation with a seasoned Houston DWI lawyer to determine the best strategy for your circumstance.

Why Does Auto-Brewery Syndrome Happen?

It is normal for everyone to have some fermentation in their gut. It is part of the digestive process that helps to break down food. But when a person experiences auto-brewery syndrome, the fermentation happens in another part of the digestive tract and specific types of fungi are present. The overgrowth of fungus shifts the balance of the gut’s microorganism balance. The condition is commonly experienced with comorbid conditions, such as diabetes, liver disease, Crohn’s disease, short bowel syndrome, or an autoimmune condition.

Some of the symptoms an individual could experience include the following:

  • Dizziness
  • Fatigue
  • Slurred speech
  • Sudden mood shifts
  • Belching
  • Vomiting
  • Nausea
  • Headaches
  • Balance issues
  • Confusion

Before an official diagnosis, it is possible for an individual to experience symptoms without ever knowing the fermentation is occurring. Once properly diagnosed, a doctor can treat the symptom. Often antifungal medications are prescribed.

Can Auto-Brewery Syndrome Be a DWI Defense?

It is not likely auto-brewery syndrome can be used as a DWI defense because it is not a common diagnosis. Due to the syndrome being rare, it is not typically used as a defense strategy when a person is facing a DWI charge. Of course, if there is a history of the issue and it has been diagnosed in the past, the possibility of bringing up auto-brewery syndrome could be a possibility.

While the cause of the syndrome is not always clear, there are times when doctors can connect the syndrome to antibiotic use or a person’s diet. Long-term antibiotic use can interfere with gut health, causing an overgrowth of yeast. Some research also points to diets high in carbohydrates such as white bread, white rice, pastas, high fructose corn syrup, and desserts being contributing factors.

Talk to your primary care doctor about any health concerns you feel could have contributed to your arrest. Also, connect with a Houston DWI lawyer to determine the best path forward. For example, an attorney can look at the facts, including if you were arrested due to a blood alcohol reading or visual signs of impairment, and determine the best defense strategy.
