Answer

The most common causes of metabolic alkalosis are the use of diuretics and the external loss of gastric secretions. Causes of metabolic alkalosis can be divided into chloride-responsive alkalosis (urine chloride < 20 mEq/L), chloride-resistant alkalosis (urine chloride >20 mEq/L), and other causes, including alkali-loading alkalosis.
