Mr. Pey frequently takes antacids, which contain bicarbonate salts, to battle his upset stomach. Determine the type of acid-base imbalance created by frequent antacid consumption and predict the compensation for his problem
What will be an ideal response?
Mr. Pey has created a pH imbalance known as metabolic alkalosis by frequently consuming antacids. Compensation for metabolic alkalosis is both respiratory and renal. The respiratory response to a decreased hydrogen ion concentration is hypoventilation. This retains carbon dioxide and increases the number of hydrogen ions in the body. The renal response to metabolic alkalosis involves the retention of hydrogen ions by the kidneys and bicarbonate ions are secreted into the urine.
