Tums are a type of antacid that is used to relieve heartburn, sour stomach, acid indigestion, and upset stomach associated with these symptoms. The active ingredient in Tums is calcium carbonate, which works by reducing the amount of acid in the stomach. When you take Tums, the calcium carbonate reacts with the acid in your stomach to form calcium chloride, water, and carbon dioxide, which neutralizes the acid.

In addition to relieving heartburn and other stomach-related symptoms, Tums may also be used to increase calcium levels in your body. Calcium is a mineral that plays an important role in building strong bones and maintaining heart health.

Its important to note that Tums may have mild side effects like constipation and gas. If you have certain health conditions like kidney problems, liver failure, or heart failure, you may be at a higher risk of some of the side effects of Tums. Its also important to drink plenty of fluids while taking Tums to lower your risk of certain side effects like constipation and kidney stones. If you need Tums for more than 2 weeks, its recommended to talk to your healthcare provider.
