Hypochloremia

Abnormally decreased concentration of chloride ions in the blood (normal range: 96-106 mmol/L (or mEq/L), often associated with disorders of fluid balance and acid-base homeostasis, including metabolic alkalosis or chronic respiratory acidosis. Possible causes are GI loss (vomiting, nasogastric tube, diarrhea), excessive sweating, burn injury, medications (loop diuretics), kidney failure, adrenal insufficiency, heart failure, SIADH, and emphysema (respiratory acidosis resulting in a compensatory loss of chloride).
