Get rid of foods that cause problems
Certain foods are more likely to cause irritable bowel syndrome (IBS) like symptoms or to make them worse. Examples include dairy products, artificial sweeteners, alcohol and caffeine, fatty foods and foods that cause gas, like beans. Asking a dietitian for advice on a diet that could help manage the condition maybe be beneficial.
