Flatulence (Gas)

Many people with IBS say they’re extremely gassy. It’s not clear why. They don’t seem to make more gas than anyone else, but it seems to bother them more. Studies have found people with IBS have trouble getting rid of gas, possibly because of problems with how the nerves and muscles in their gut work. Their intestines also may be extra sensitive. Even a normal amount of gas may cause pain.

Dealing with IBS and gas is hard. Symptoms vary widely from one person to the next, and no single treatment works for everyone. What gives someone else gas may not bother you at all. What brings you relief may have no effect on someone else. There are many different strategies you can try. Most have to do with what you eat.

Gas-Producing Foods

Because IBS different for everyone, it may help to keep a food diary to see what triggers your symptoms. Once you know the problem foods, you can avoid them.

Foods on most people’s lists include:

  • Beans and other legumes like peas, peanuts, and lentils
  • Cabbage
  • Raw broccoli and cauliflower
  • Onions
  • Brussels sprouts
  • Raisins


Often when people are prescribed the Low Fodmap diet they are recommended to eat more fibre.   Unfortunately fibre can often make gas worse.  Consult your dietitian to determine the best method of reducing gas whilst maintaining an appropriate fibre intake.
