Everyone produces gas. In IBS two things change: fermentation patterns can shift, and the gut becomes more sensitive, so an ordinary volume of gas registers as pain or distension.
What adds to the volume
Air swallowed while eating quickly or talking through a meal, aerated drinks, long gaps followed by large meals, and low physical activity all increase gas. None of these are about a single "bad food".
What raises the sensitivity
Stress, poor sleep and abdominal tension all lower the threshold at which the gut reports discomfort. This is why the same lunch can be fine on a calm Tuesday and unbearable on a difficult Thursday.
Practical steps
Eat slowly and chew properly. Keep portions moderate and intervals regular. Walk for ten minutes after meals instead of lying down. Practise gentle breathing to release abdominal tension. Then, and only then, look for specific food triggers — you will identify them far more accurately once the basics are steady.
