[edit on Wikidata] Lactic acidosis is a medical condition characterized by the buildup of lactate (especially L-lactate) in the body, with as a result an excessively low pH. It is a subtype of metabolic acidosis, where there is excessive acid due to a problem with the body's metabolism. Lactic acidosis is typically the result of an underlying acute or chronic medical condition, medication or poisoning.
