Drunk disease

First discovered in Japan, this condition is related to strains of Candida albicans which turn acetaldehyde (the chemical created by sugar and yeast fermentation) into ethanol.

Some candidiasis sufferers will feel, and appear to be, intoxicated. An unusual symptom of certain people with severe candidiasis is the presence of alcohol in the bloodstream even when none has been consumed. These candidiasis patients whose yeast turns sugar into alcohol are chronically drunk. They have developed what is only half-jokingly called "auto-brewery syndrome."
