Symptoms, conditions and causes

Why do I have an increased passing of gas?

Increased passing of gas can go together with bloating, digestive issues many other discomforts in daily life. Let’s look at the common causes and remedies for it.

Cause #1: SIBO / Excess fermentation in the intestines

SIBO stands for small intestinal bacterial overgrowth. It’s a condition where a good portion of your friendly bacteria is in the wrong place--it’s in the small intestine instead of mostly in the large intestine where it should be. If you have SIBO you may have a lot of bloating, abdominal pain, passing of gas etc. This is because food starts to ferment in the wrong place which releases different types of gases in the colon.

You can get a hydrogen/methane breath test kit. The test is inexpensive but you may need a prescription to buy one. The test will confirm whether or not you have SIBO.


  • Improve the stomach acidity to digest better in the stomach:

    • take apple cider vinegar (1 to 2 teaspoons stirred into about a cup of water, before your meals)

    • take betaine hydrochloride (before your meals)

On a temporary basis, do the following:

  • avoid foods with fiber for 3 to 6 weeks (including vegetables)

  • avoid probiotics

  • avoid fermented vegetables

  • Consume purified bile salts (right after the meal)

  • Avoid dairy

  • Consume moderate amounts of protein

  • Avoid consuming refined carbs and sweets

  • Do intermittent fasting and prolonged fasting

    Other causes:

  • History of consuming antibiotics

  • Lack of stomach acidity

  • Consuming vegetables that you are not used to
