Although passing gas or its odor may cause embarrassment, it is a natural and common occurrence.[1] The average person passes gas between 10 and 20 times per day and most patients who report excessive flatulence actually fall within this range [2] Not only can gas cause embarrassment, but increased gas production can cause bloating and abdominal pain. Additionally, gas can be expelled from the body by belching as it escapes from the stomach through the esophagus.

Method 1
Method 1 of 2:

Dealing with Gas

  1. 1
    Try an over-the-counter remedy. Digestive aids, such as Beano, are available and may help reduce gas production. Beano contains an enzyme called beta-galactosidase that breaks down certain sugars found in beans and vegetables like broccoli. Some scientific studies have shown reduced flatulence with the use of beta-galactosidase. [3] [4] [5]
  2. 2
    Try activated charcoal. Activated charcoal is different than the charcoal that you use to grill. Activated charcoal can be bought in a pharmacy and may be used to reduce flatulence. Scientific studies on the effectiveness of activated charcoal in reducing gas are controversial. [6] [7] [8]
    • Some studies of oral administration of activated charcoal observed reductions in the amount of gas released from the colon, while other studies found no differences. These results suggest that activated charcoal may have a minor benefit in certain circumstances. It is possible that activated charcoal only beneficially reduces gas production due to some etiologies, but not others.

  3. 3
    Use a deodorizer. Many different deodorizers can be used to disguise the scent of flatulence. Interestingly, charcoal-lined undergarments can be purchased that claim to deodorize the scent of gas. Their clinical effectiveness has not been examined.
  4. 4
    Embrace Mother Nature. Passing gas is a natural phenomenon that is essential for the removal of gaseous waste from the body. Everyone does it. Although holding in gas may be appropriate in some situations, you may find if you continue to do this, you could experience abdominal cramping and discomfort.
    • Excuse yourself to the restroom to pass gas.
    • Wait to pass gas until you are alone or in a well-ventilated space.
    • If you pass gas in public, politely say excuse me.
    • Use your discretion. Passing gas in front of close friends or family may be appropriate and establishing these norms may help reduce the negative stigma of passing gas.
  5. 5
    Make the best out of an awkward situation. If you noticeably pass gas in public, don’t be embarrassed. Make a joke about it, for example, by suggesting that you quickly move to a new location to escape the smell. Frankly, if it is especially odorous, most people will appreciate your candor and will gladly relocate with you. Making light of this potentially awkward situation may be especially helpful if this is a chronic problem.

Method 2 of 2:

Preventing Gas

  1. 1
    Reduce the amount of air swallowed.[9] Sometimes excess gas can be caused by swallowing too much air.[10] This can happen when you eat too fast or may be done unconsciously. Unconscious swallowing of air (aerophagia) is often associated with emotional stress and stress reduction techniques may prove beneficial.[11] [12]
    • Eat slower. Rapid ingestion of food can lead to swallowing air, which can increase gas production. Focus on eating slower, perhaps by chewing food a certain number of times before swallowing. Not only will this reduce the amount of air swallowed during eating, but eating slower has been associated with decreased calorie intake. [13]
    • Stop chewing gum and smoking, both of which can increase the amount of air that is unconsciously swallowed.[14]
  2. 2
    Keep a food journal. Every body is different and you may find that your body is more sensitive to some foods than others. Keeping a record of what you ate and your symptoms may help you identify different foods that may be causing increased gas production.
    • Once you have identified which foods cause you problems, start eliminating them from your diet one at a time. You can also try eliminating all the foods that may cause gas, then slowly reintroduce them into your diet.[15]
  3. 3
    Avoid foods that are known to cause gas. Some foods are more apt to cause gas than others.[16] This may be due to the body’s inability to properly digest certain foods, such as those containing short chain carbohydrates, called FODMAPs (fermentable oligo-, di-, and monosaccharides and polyols).[17] [18] Additionally, starch and soluble fiber can contribute to increased gas.[19] Below is a list of foods to avoid to reduce gas:
  4. 4
    Determine if you have food intolerances. Some individuals are incapable of digesting certain foods, which can lead to increased gas production.[24] A medical professional can help you determine if you have a food intolerance and help you plan a well-balanced diet that accommodates your dietary restrictions.
    • Lactose intolerance is a common occurrence and results from a deficiency in the lactose-digesting enzyme, lactase. To determine if you are lactose-intolerant, follow these guidelines. [25] Some individuals with lactose intolerance find it helpful to take lactase supplements, such as Lactaid, when eating dairy products. Supplementation with lactase should help your body digest lactose and reduce gas.
    • Other carbohydrate malabsorption conditions can result in increased gas production.[26] For example, if you frequently experience increased gas after eating foods containing high fructose corn syrup, you may have fructose malabsorption.[27] Keeping a journal, as mentioned above, will help you to identify which foods result in increased gas production.
  5. 5
    Get checked out for a more serious problem. Rarely, increased gas may be a sign of a more serious medical problem. Increased intestinal gas can be a sign of celiac disease (gluten intolerance),[28] irritable bowel syndrome,[29] or a bacterial infection[30] . Consult your doctor if you experience any of the following symptoms:
    • Diarrhea
    • Changes in the color or frequency of stools
    • Bloody stools
    • Severe abdominal pain
    • Unexplained weight loss

    Bloating is typically caused by either air swallowing or certain foods. When you drink soda, for example, you tend to get a little bloated because you're swallowing air in the bubbles. Bloating can also be caused by something you’ve eaten that's getting fermented in the bowel, which creates gas.
