Miscellaneous causes of metabolic alkalosis include villous adenomas, which are a rare cause of diarrhea. Villous adenomas usually lead to metabolic acidosis from loss of colonic secretions that are rich in bicarbonate, but occasionally these tumors cause metabolic alkalosis. The mechanism is not well understood.ydrogen ions may be lost through the kidneys or the GI tract. Vomiting or nasogastric (NG) suction generates metabolic alkalosis by the loss of gastric secretions, which are rich in hydrochloric acid (HCl). Whenever a hydrogen ion is excreted, a bicarbonate ion is gained in the extracellular space.
