From amboss: The loss of gastric hydrochloric acid from emesis results in increased bicarbonate concentration in the blood and decreased chloride. Some potassium is also lost through vomiting. Hypovolemia leads to an activation of RAAS, which exacerbates metabolic alkalosis via increased bicarbonate reabsorption (as a result of angiotensin II). Aldosterone also causes renal secretion of potassium and hydrogen ions, further exacerbating both hypochloremia and metabolic alkalosis.
