Lactic acidosis is a medical condition characterized by an excess of lactic acid in the bloodstream, leading to a decrease in blood pH. This can occur when the body produces lactic acid faster than it can be removed, often due to intense exercise, certain diseases, or conditions that reduce oxygen supply to tissues. Symptoms of lactic acidosis may include rapid breathing, nausea, weakness, and confusion. It can be a serious condition requiring medical attention, as it may indicate underlying health issues such as sepsis, shock, or diabetes. Treatment typically focuses on addressing the underlying cause and restoring normal acid-base balance.
