No. Foods do not cause IBS. But some foods may make you feel worse. Foods that make symptoms worse include foods high in fat or caffeine. Fat and caffeine can cause your intestines to contract, which may cause cramping. Alcohol and chocolate may also make you feel worse. If gas is a problem for you you might want to avoid foods that tend to make gas worse. These include beans, cabbage and some fruits.
Keeping a diary of what you eat and your symptoms for a few weeks is a good way to determine if a food bothers you. If you think a food makes you feel worse, do not eat it. But do not cut out foods unless they have caused you problems more than once.
How can stress affect IBS?
Stress can trigger symptoms in people with IBS. Talk to your family doctor about ways to deal with stress such as exercise, relaxation training or meditation. He or she may have some suggestions or may refer you to someone who can give you some ideas. Your doctor may also suggest you talk to a counselor about things that are bothering you.
