This can usually be reversed by treatment with a saline solution. The most common causes are volume depletion (particularly when involving loss of gastric acid and chloride (Cl) due to recurrent vomiting or nasogastric suction) and diuretic use. The juxtaglomerular cells detect this reduction in renal blood flow and release renin, which activates the renin-angiotensin system and synthesizes angiotensin II. Miscellaneous causes of metabolic alkalosis include villous adenomas, which are a rare cause of diarrhea. Common triggers for hyperventilation include anxiety, fever, pain, and certain medications.
