Acid indigestion is a type of indigestion involving an excess of hydrochloric acid in the stomach. Frequent occurrence of acid indigestion can lead to aggravation of the duodenum or to an aggravation of the lining of the stomach, both of which can lead to ulcers which can be life-threatening. It should be distinguished from heartburn, which typically involves aggravation of the esophagus.

Common contributors to acid indigestion are:

1. Eating foods with too much fat in them.
2. Eating foods with too much spice in them.
3. Excess consumption of
   1. Alcohol
   2. Caffeine
4. Smoking
5. Overeating
6. Eating too late in the evening, or eating just before sleeping.

Over the counter remedies (antacids) are available at almost all grocery stores and drugstores. However, a kind of dependence can develop on these medications, and other complications can arise from excess use of antacids.
