What is a common cause of metabolic acidosis?

Metabolic acidosis occurs when there is an excess of acid in the body or a loss of bicarbonate, resulting in a decrease in blood pH. Diabetic ketoacidosis is characterized by the production of excess ketone bodies from fat metabolism, particularly in individuals with uncontrolled diabetes. These ketones are acidic and lower the pH of the blood, leading to metabolic acidosis. Therefore, this condition is a common and significant cause of metabolic acidosis, as it directly contributes to an increased acid load in the body.

While other conditions such as lactic acidosis, renal failure, and chronic diarrhea are also associated with metabolic acidosis, the question asked specifically for a common cause. Diabetic ketoacidosis is often emphasized in discussions about metabolic causes, especially among diabetic patients, making it a widely recognized and significant example in clinical settings.
