Gas: Symptoms, Causes, Treatment


Gas is air in your digestive tract. You make it when you swallow air and when the bacteria in your large intestine help digest food. You get rid of gas in two ways: through your mouth (burping) or through your anus (flatulence).

Flatulence is excess gas in your stomach or intestines. It can lead to bloating and flatus containing small amounts of sulfur. The more sulfur flatus contains, the more of an odor it will have.

Gas is a natural consequence of swallowing and digestion. Everyone has gas. The average adult passes gas between 13 and 21 times a day. But having too much gas is uncommon. It may sometimes indicate a digestive disorder.


Though symptoms vary from person to person, common symptoms of gas involve burping, passing gas, bloating, and pain or discomfort in your abdomen.


Since gas enters your digestive tract when
you swallow air and when the bacteria work to break down undigested foods, you are
likely to have more gas if you swallow more air or eat certain foods.

If your doctor thinks there is a certain condition that causes excess gas or symptoms, more tests may be ordered.
