While flatulence affects all people and is considered a normal part of life, it can be embarrassing to pass gas when it’s accompanied by an unpleasant, smelly odor. If you have frequent, smelly gas, there are ways to get rid of it. Adjust your eating habits to make gas less likely. [1] Stay away from foods that tend to cause smelly gas. If your gas does not go away with home treatment, talk to a doctor about ways to eliminate gas.

Coping in the Moment

  1. Everyone produces gas, and some days your gas may be smelly. If you're gassy on a given day, try holding your gas in during moments where it may be embarrassing to pass gas. You can wait for a discreet moment, such as when you're alone in your office, to pass gas.
    • However, do not hold in gas to the point you experience pain. Holding in gas for too long can cause indigestion, bloating, and other medical issues.
  2. It is okay to excuse yourself to run to the bathroom, even if it's just to pass gas. If you feel gas coming, quietly excuse yourself and make a trip to the bathroom. You can then pass gas discreetly and return to your day.
    • If possible, opt for a private bathroom so you don't have to pass gas in the presence of others.

  3. If you tend to get gassy after meals, take medications designed to reduce gas just before eating. Medications such as Beano and charcoal tablets are taken before a meal to prevent gas afterwards. Refer to the instructions on the bottle before using these medications. Most medications of this kind must be taken before a meal to be effective. [2]
    • Before taking a new medication, check with your doctor to make sure it is okay given your current health and existing medications.
  4. If you're already experiencing gas, try taking some over-the-counter medications designed to minimize gas. Products that contain simethicone, such as Gas-X, Gelusil, Mylanta, and Mylicon, help break down gas bubbles. While their effectiveness has not been widely studied, some find such products minimize gas. [3]

Adjusting Your Eating Habits

  1. Eating in larger portions can cause food to digest in greater amounts quickly. This can lead to excessive gas. To cut back on gas, try eating small meals throughout the day in tiny portions. Instead of having a heavy sit down breakfast, for example, eat something light in the morning, like a couple of hardboiled eggs, and then have light snacks throughout the day. [4]
  2. Eating quickly can increase gas. Try to eat slowly. Set down your fork between bites and chew your food thoroughly before swallowing. [5]
    • It can help to set a timer for 20 to 30 minutes and try not to finish your food until your timer goes off.
  3. Swallowing air can lead to excessive gas. Chewing gum, drinking through a straw, and sucking on hard candies all cause you to swallow more air. [6] Limit how often you engage in these activities to cut back on gas. [7]
  4. [8] Carbonated beverages, like sodas and seltzer waters, can increase gas. [9] To help prevent gas, stick to drinking water with meals. Not only will this prevent gas, it has no calories and will quench your thirst quicker than other beverages.
  5. Fruits and vegetables that have soluble fiber are broken down in the body in a fashion that can cause gas. [11] To lessen your gas, avoid the following fruits and vegetables: [12]
    • Onions
    • Artichokes
    • Pears
    • Brussels sprouts
    • Broccoli
    • Asparagus
    • Beans
    • Dairy [13]
  6. Artificial sweeteners found in sugar-free candies can cause gas. [14] Read labels of sweet products you buy and watch out for sweeteners such as sorbitol, mannitol and xylitol. These could be contributing to your overall gas. [15]
  7. While certain foods in general cause gas for most people, everyone's body is different. You may process certain foods differently, leading to excessive or smelly gas. Keep a food diary and write down everything you eat, as well as when you experience smelly gas. This will help you identify foods that are causing you gas.
    • For example, say you had a salad for lunch that included artichokes and onions. If you notice gas later in the day, these vegetables may be the cause.

Seeking Medical Help

  1. If your gas is not causing other health problems, you can treat it with over-the-counter medications. A variety of medications you can find at most drug stores can help eliminate or lessen gas. [16]
    • Taking two to four tablespoons of an antacids about half an hour after a meal can reduce gas.
    • Two to four charcoal tablets can help with gas.
    • If you are lactose intolerant, try the enzyme lactase.
    • To reduce the odor of your gas, try Bismuth subsalicylate ( such as Pepto-Bismol).
  2. Gas is not usually a major medical concern. However, when accompanies by other GI issues, gas warrants a doctor's visit. See a doctor if any of the following problems accompany your gas: [17]
    • Abdominal pain and bloating
    • Recurring diarrhea or constipation
    • Blood in your stools
    • Signs of an infection (fever, vomiting, chills, muscle pain)
  3. If your doctor finds out your gas is caused by an underlying medical condition, they may prescribe you medication. You may require medication for irritable bowel syndrome or antibiotics if you have a stomach infection. Take any medication exactly as instructed by your doctor and ask any questions you have in the office. [18]

    Lactose intolerance can cause tremendous gas. If you can't digest milk, the sugar lactose will get broken down and fermented in the colon. This can cause gas, bloating and ultimately, diarrhea. People with celiac disease are very sensitive to one of the constituents of gluten, gliadin. Since they can't digest it, gases form.

    Gas is usually caused by something you've eaten or swallowing air. People with celiac disease cannot digest gluten, which causes gases to form. If you have celiac, you'll need to stay away from gluten products. If you are lactose intolerant and cannot digest dairy, the sugar lactose will get broken down and fermented in the colon. This causes tremendous gas and bloating.

      Article Summary X

      To get rid of smelly gas, try eating your food more slowly, since digesting food in a hurry produces more gas. In addition, you'll be better off eating smaller meals more regularly than larger meals because digesting larger amounts of food quickly can cause gas. Try to avoid eating fruits and vegetables that produce gas, like pears, broccoli, or onions. You could also try sticking to water rather than drinking carbonated beverages, which produce gas. Additionally, avoid artificial sweeteners such as those in sugar-free candy. To find out which medication you can take to combat gas, read on!
