Hal and Ray both say they are living with Auto-Brewery Syndrome (ABS), a rarely diagnosed condition in which the body produces ethanol without drinking, causing symptoms of moderate to severe intoxication in those it affects.

Hal says that generally, he only remembers “bits and pieces” of his ABS episodes, and then, usually, only after the fact. His son, Tristan, and Hal's long-time girlfriend, Stephanie, say that when Hal is in the midst of an ABS event, he becomes verbally abusive, belligerent, and sometimes physically aggressive. They also say he has been known to fall down and injure himself.

Ray, who was involved in a vehicle crash in 2013 that left him with multiple injuries, was charged with DUI, reckless driving, and criminal mischief but insists he didn’t have a single drop of alcohol prior to the accident. His wife, Sierra, says she looked for evidence that Ray was drinking in secret until she learned about ABS.

“It’s an ever-evolving science,” says Dr. Anup Kanodia, a functional medicine doctor who has treated both men in the past with limited success. Watch the video above to hear what he says are the newest available treatments for Auto-Brewery Syndrome, plus hear why Dr. Prasanna Wickremesinghe, a gastroenterologist who has also treated both Ray and Hal, says some doctors may be missing the ABS diagnosis.
