Clinical information:

D-lactate is produced by bacteria in the colon when there is an excess supply of carbohydrates as a result of sugar malabsorption. D-lactate is absorbed from the intestine and results in D-lactate acidosis, with neurological manifestations including slurred speech, confusion, hallucinations, unsteady gait, and abusive behavior. Dlactate acidosis is typically seen in individuals with short bowel syndrome and can be indicative of sepsis, ischemia, and trauma.
