Article Excerpts about GAS

Why Do I Have Gas: NIDDK (Excerpt)

Everyone has gas. Burping or passing gas through the rectum is normal. Because it is embarrassing to burp or pass gas, many people believe they pass gas too often or have too much gas. They do not realize that passing gas 14 to 23 times a day is normal. An occasional burp during or after meals is normal, too. It is rare for a person to have too much gas.

Most of the time gas is odorless. The odor comes from sulfur made by bacteria in the large intestine. Sometimes gas causes bloating and pain. Not everyone has these symptoms. It probably depends on how much gas the body makes and how sensitive a person is to gas in the large intestine. (Source: excerpt from Why Do I Have Gas: NIDDK)

Most people produce about 1 to 3 pints a day and pass gas about 14 times a day. (Source: excerpt from Gas in the Digestive Tract: NIDDK)
