Bloating and trapped wind are two of the most common digestive complaints, and also two of the most frustrating, because so many things can cause them, from how quickly you ate to what you ate to how your gut is functioning generally.
What causes bloating and trapped wind?
Swallowing air while eating too quickly, talking while eating, or drinking through a straw
Carbonated drinks
High-fibre or gas-producing foods (beans, cruciferous vegetables, onions)
Constipation, which slows everything down and lets gas build up
Food intolerances, where certain foods trigger excess gas as they're fermented by gut bacteria
Stress, which affects gut motility more than most people realise
Quick ways to relieve trapped wind
Gentle movement, a short walk can help gas move through the digestive system
Peppermint tea, which can help relax the digestive tract
Warm compress on the stomach
Avoiding carbonated drinks and chewing gum, both of which introduce extra air
Eating more slowly and avoiding talking with a full mouth
Most trapped wind resolves on its own within a few hours and isn't a cause for concern.
When bloating might point to a food intolerance
If bloating is a one-off after a particularly rich or unusual meal, it's probably nothing to investigate further. But if it happens regularly, after a wide range of meals, or alongside other symptoms like fatigue, skin issues or irregular bowel habits, it's worth considering whether a specific food or group of foods is behind it.
Common intolerance-linked bloating triggers include:
Gluten
Dairy/lactose
Certain fruits and vegetables high in FODMAPs (onion, garlic, some fruits)
Yeast
A food intolerance test can help narrow this down by flagging which foods your body is reacting to most strongly, rather than relying on trial and error with your whole diet at once.
When to see a GP instead
Bloating alone is rarely serious, but see a GP if it's:
Persistent and doesn't improve with simple changes
Accompanied by unexplained weight loss
Paired with a noticeable change in bowel habits that lasts more than a few weeks
Accompanied by blood in your stool or persistent pain
These aren't typical intolerance symptoms and deserve a medical opinion rather than self-testing.
