Is Vomiting Metabolic Acidosis?

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.

Can vomiting cause metabolic acidosis?

Outlook of metabolic alkalosis

Metabolic alkalosis most commonly results from severe cases of vomiting that cause you to lose the acidic fluids in your stomach. This can usually be reversed by treatment with a saline solution. It can also be the result of a potassium deficiency or a chloride deficiency.

Does vomiting and diarrhea cause metabolic acidosis?

Severe diarrhoea

This can cause either a metabolic acidosis or a metabolic alkalosis. Development of a significant acid-base disturbance requires a significant increase in stool water loss above its normal value of 100 to 200 mls/day.
