Overview

Gas in your digestive system is part of the normal process of digestion. Getting rid of excess gas, either by burping or passing gas (flatus), also is normal. Gas pain may occur if gas is trapped or not moving well through your digestive system.

An increase in gas or gas pain may result from eating foods that are more likely to produce gas. Often, relatively simple changes in eating habits can lessen bothersome gas.

Certain digestive system disorders, such as irritable bowel syndrome or celiac disease, may cause — in addition to other signs and symptoms — an increase in gas or gas pain.
