Final answer:
Chronic use of calcium carbonate or sodium bicarbonate antacids can increase the risk for metabolic alkalosis, characterized by an excess of bicarbonate in the blood. This can occur due to excessive ingestion of antacids or other substances containing bicarbonate. Other causes of metabolic alkalosis include vomiting, potassium depletion, and the use of diuretics for hypertension.
Step-by-step explanation:
Chronic use of calcium carbonate or sodium bicarbonate antacids can lead to an increased risk for metabolic alkalosis. This condition occurs when there is an excess of bicarbonate in the blood, which can happen due to the ingestion of excessive amounts of antacids or other substances that contain bicarbonate. Other causes of metabolic alkalosis include vomiting, potassium depletion, and the use of diuretics for hypertension.
