Patient information: Gas and bloating

Some people feel that they pass too much gas from below (flatulence) or burp too frequently, both of which can be a source of embarrassment and can be uncomfortable. However, most people who complain of excessive gas do not produce more than the average person. Instead, they probably have increased awareness of normal amounts of gas. On the other hand, several foods and certain medical conditions are associated with excessive gas production. Understanding the sources of intestinal gas, conditions possibly associated with increased sensitivity to gas, and measures that may help to reduce symptoms can offer relief to many patients.
