A 61-year-old Texan came stumbling in an emergency room due to severe dizziness. But when a breathalyzer test was conducted, his blood has alcohol content that is five times than the allowed contest for driving in the state, NPR reports. What makes this news one of a kind is that he has not taken any alcohol at all for that day.

The condition of the Texan triggered the curiosity not just of his own wife but also of various medical experts. A team conducted an experiment to make sure that the guy's problem is not just merely "closet drinking." They isolated the man for 24 hours in a hospital room and he was only given foods that are rich carbohydrates. When they checked his blood occasionally throughout the day, the alcohol content reached about 0.12 percent on its own.

The answer to the mystery? The Dean of Nursing at the Panola College Barabara Cordell and Dr. Justin McCarthy, a gastroenterologist found that there is too much brewer's yeast in the gut of the guy.

It is a medical condition called Saccharomyces Cerevisiae that happens inside the stomach of the guy. The more he ate starchy foods, the more that the yeast content ferments all the sugar into ethanol that makes pure alcohol inside his body; thus, making him drunk, according to Daily Mail UK.

As a solution, the doctors involved in the study lessened the overall amount of carbohydrates in his everyday diet and even treated the Texan with several antifungals, as mentioned by Yahoo News Canada.

Other similar reports can be traced back during the 70s in Japan when the said infection happened after a certain patient took some antibiotics. It wiped out the bacteria in the person' stomach but made room for some fungi similar to yeast which flourished.
