Can medications cause intestinal gas?

See your health care provider as soon as possible (gastroenterologist), for consultation. Gas and gas pains can strike at the worst possible moment--during an important meeting or on a crowded elevator. And although passing intestinal gas (flatus) usually isn't serious, it can be embarrassing.

Anything that causes intestinal gas or is associated with constipation or diarrhea can lead to gas pains. These pains generally occur when gas builds up in your intestines, and you're not able to expel it. On average, most people pass gas at least 10 times a day.

The good news is that although you can't stop gas and gas pains, a few simple measures can help reduce the amount of gas you produce and relieve your discomfort and embarrassment.

For most people, the signs and symptoms of gas and gas pain are all too obvious. They include:

The voluntary or involuntary passing of gas, either as belches or as flatus.

Sharp, jabbing pains or cramps in your abdomen. These pains may occur anywhere in your abdomen and can change locations quickly.

A "knotted" feeling in your abdomen.

Swelling and tightness in your abdomen (bloating).

Gas pains are usually intense, but brief. Once the gas is gone, your pain often disappears. In some cases, however, the pain may be constant or so intense that it feels like something is seriously wrong.

Gas can sometimes be mistaken for:

Heart disease

Gallstones

Appendicitis

Some products may help, but they aren't always effective. Consider trying:

Beano.

Lactase supplements.

Simethicone.

Activated charcoal.
