A 61-year-old Texas man admitted to a hospital not long ago appeared to be falling-down-drunk, even though he denied having had even a single drink. It was discovered he was unintentionally manufacturing beer in his stomach. With "auto-brewery syndrome," stomach-based yeast automatically ferments all starches (even vegetables or grains) passing through, converting them to ethanol. Normally, natural stomach bacteria control the yeast, but if, for example, antibiotics had inadvertently eliminated the bacteria, the yeast would prevail. The case was reported in a recent International Journal of Clinical Medicine.
