D-lactic acidosis is a medical condition characterized by an accumulation of D-lactic acid in the body, leading to a decrease in blood pH. This condition often occurs in individuals with certain metabolic disorders, particularly those with short bowel syndrome or those who have undergone extensive intestinal surgery. It can also arise from excessive carbohydrate fermentation in the gut. Symptoms of D-lactic acidosis may include confusion, slurred speech, and difficulty breathing. Diagnosis typically involves measuring blood lactate levels, and treatment focuses on addressing the underlying cause, such as dietary modifications or medications to manage symptoms and restore normal acid-base balance.
