For many people with IBS, bloating is the symptom that shows up every day: a tight, swollen belly that gets worse as the day goes on and makes clothes feel uncomfortable by the evening. Here's what's behind it and how to get relief.
Why IBS causes bloating
IBS bloating usually isn't caused by "too much gas" alone. Several things combine:
- A sensitive gut: normal amounts of gas feel uncomfortable or painful (visceral hypersensitivity)
- Fermentation: certain carbohydrates (FODMAPs) are fermented by gut bacteria, producing gas
- Slow transit: especially in IBS-C, gas and stool move slowly and build up
- Muscle reflexes: in some people, the abdominal wall relaxes and the diaphragm pushes down, making the belly visibly expand
- Stress: the gut–brain connection can make the gut more reactive (see why stress triggers IBS)
9 ways to relieve IBS bloating
1. Apply warmth to your belly
Heat relaxes the abdominal muscles and can ease that tight, stretched feeling within minutes.
2. Gentle clockwise massage
Massaging in the direction of your large intestine can help gas move along. Our step-by-step massage guide shows you how.
3. Take a short walk
10–15 minutes of walking after meals helps the gut move gas through.
4. Try yoga poses for gas
Child's pose, knees-to-chest and gentle spinal twists can relieve trapped wind.
5. Eat slowly and chew well
Eating fast means swallowing more air. Put your fork down between bites.
6. Swap high-FODMAP foods
Common culprits include onion, garlic, beans, wheat, apples and some sweeteners. A guided low-FODMAP diet can identify your personal triggers.
7. Limit fizzy drinks and chewing gum
Both add air to your gut. Sugar-free gum also often contains sugar alcohols, which are high-FODMAP.
8. Try peppermint
Peppermint tea or enteric-coated peppermint oil capsules relax gut muscles. (Avoid them if you have reflux.)
9. Practise belly breathing
Slow diaphragmatic breathing can help retrain the abdominal reflex that makes the belly push outwards, and calms the nervous system too.

When bloating needs a doctor
See a doctor if bloating is new, persistent and getting worse, or if it comes with weight loss, blood in the stool, vomiting or a feeling of fullness after eating very little.
