There are many things that cause intestinal gas. One common cause is swallowed air. Each time we swallow, air enters the digestive tract. Smoking, eating too fast, poorly fitting dentures, hiccups, blocked nasal passages and chewing gum all contribute to the amount of air we swallow. Gas is produced in our bodies everyday.
Gas has to be released either from the mouth or the rectum.
Abdominal bloating and cramping or pain can occur when there is a build up of gas in the stomach, or intestines. Certain foods can cause gas, as we probably all have heard. Beans, brussel sprouts, cauliflower, high fiber grains, onions, and dairy products all produce gas. People who are lactose intolerant have a big problem with gas, because they lack the enzyme lactase to digest dairy products. People with gallbladder problems, hernias, anxiety problems, or colon disorders suffer more with gas.
