How do Tums help heart burn?

Tums help relieve heartburn by neutralizing stomach acid, which can cause discomfort when it backs up into the esophagus. The active ingredient, calcium carbonate, reacts with the acid to form water and other neutral compounds, providing quick relief from the burning sensation. Additionally, by increasing the pH level in the stomach, Tums can help alleviate symptoms associated with acid reflux. However, they are meant for occasional use and not as a long-term solution for chronic heartburn.
