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. Common causes of lactic acidosis include sepsis, shock, and diabetes. Symptoms may include rapid breathing, confusion, and fatigue. Treatment typically focuses on addressing the underlying cause and may involve intravenous fluids or medications to restore normal acid-base balance in the body.
