A Texas man, 61, suffers from a rare condition where his body brews booze in his stomach, a medical journal says.
The man baffled doctors after he showed up at an emergency room wicked drunk in 2010 and claimed he hadn't a drop of liquor.
"He would get drunk out of the blue — on a Sunday morning after being at church, or really, just anytime," said Barabara Cordell, the dean of nursing at Panola College in Carthage, Texas, NPR reported.
Doctors found the man's blood-alcohol volume to be .37% — nearly five times the state's legal limit, according to a recent case study published in the International Journal of Clinical Medicine.
Doctors initially thought he might be a closet drinker, but he was later diagnosed with so-called auto-brewery syndrome — where his stomach ferments any carbohydrates he eats, such as bagels, pasta, and pop, and turns it into ethanol.
The man was treated with anti-fungal medication and put on a strict no-carb, no-sugar diet.
Only a handful of people around the world have been reported to have the unusual condition, the study said.
