​Differential diagnosis of saline responsive causes of metabolic alkalosis

​Differential diagnosis of saline responsive causes of metabolic alkalosis:
-renal alkalosis due to diuretic therapy, post hypercapnia and poorly reabsorbable anion therapy such as carbenicillin, phosphate, sulfate, penicillin
-gastrointestinal alkalosis due to loss of HCI from vomiting or nasogastric suction
-intestinal alkalosis due to chloride diarrhea
-exogenous alkalosis NAHCO3, antacids, transfusions, sodium citrate, lactate, acetate, gluconate,
-contraction alkalosis
