A food intolerance is difficulty digesting certain foods and having an unpleasant physical reaction to them.
According to the NHS, a food intolerance can lead to bloating when:
Your bowel does not empty properly
- The food causes gas to be trapped
- Too much gas is produced as a reaction to the food.
“The most common foods to cause problems are wheat or gluten and dairy products,” says the health body.
It adds: “The best approach if you have a food intolerance is to eat less of the problem food or cut it out completely.”
