What do antacids do?

Antacids are medications designed to neutralize stomach acid, providing relief from heartburn and indigestion. They work by increasing the pH level in the stomach, which alleviates the burning sensation associated with excess gastric acid. This action can help ease discomfort for individuals suffering from conditions like gastroesophageal reflux disease (GERD) or acid peptic disorders.

The mechanism behind antacids involves basic compounds that react with the hydrochloric acid in gastric secretions, thus effectively reducing acidity. This characteristic makes them particularly useful when the stomach produces too much acid or when acid leaks into the esophagus. The other options present alternatives that do not align with the function of antacids, focusing instead on processes or treatments that address different physiological needs.
