Final answer:
Vomiting can result in metabolic alkalosis due to the loss of hydrogen and chloride ions. Other causes of metabolic alkalosis include diuretic use and excessive intake of antacids.
Step-by-step explanation:
Vomiting can result in metabolic alkalosis as a consequence of losing hydrogen and chloride ions through severe and prolonged vomiting. This loss of ions creates an excess of bicarbonate in the blood, leading to alkalosis. Other causes of metabolic alkalosis include diuretic use and excessive intake of antacids.
