    Gas

    Health    Gas
    Also called: Belch, Burp, Eructation, Flatulence, Flatus
    Final Step!
    Thank you!

    Everyone has gas. Most people pass gas 13 to 21 times a day. Passing gas through the mouth is called belching or burping. Passing gas through the anus is called flatulence. Most of the time gas does not have an odor. The odor comes from bacteria in the large intestine that release small amounts of gases that contain sulfur.

    Gas in the digestive tract comes from two sources: air that you swallow and the breakdown of undigested food by bacteria in the large intestine. Certain foods may cause gas. Foods that produce gas in one person may not cause gas in another.

    You can reduce the amount of gas you have by

    • Drinking lots of water and non-fizzy drinks
    • Eating more slowly so you swallow less air when you eat
    • Avoiding milk products if you have lactose intolerance

    Medicines can help reduce gas or the pain and bloating caused by gas. If your symptoms still bother you, see your health care provider.

    Questions - Gas

    Gas-X is a brand name drug from GlaskoSmithKline. It is used to provide relief of pressure, bloating, and fullness commonly referred to as gas. The active ingredient responsible for how the drug works is simethicone. Simethicone is an anti-foaming agent that is marketed to reduce the buildup of intestinal gases that cause bloating and discomforting i.e. farting. It does this by reducing the surface tension of gas bubbles causing them to break apart and pass more smoothly through your body.
    
    In theory, the action on surface tension should actually prevent or stop farting, not cause it. However, there are only a few randomized controlled trials with simethicone that show inconsistent results for gas relief. Other methods to manage gas include dietary changes, enzyme preparations to facilitate digestion, adsorbents, treatments to change gut flora, and drugs that modify gut transit.
