    A Diet for IBS With Constipation (IBS-C)

    If you have IBS-C, you may be concerned about what to eat. You need to keep a balanced diet while you avoid foods that trigger symptoms for you. Try a few simple tips to make your diet work better for you.

    Keep a Symptom Journal

    An IBS symptom journal can help you and your doctor figure out which foods may trigger your symptoms. Make a habit of writing down any symptoms you might have, along with what and how much you ate beforehand. If you see a pattern with certain foods, see if you feel better when you don't eat them, or cut back on how much of them you eat. But cut foods one at a time. If you cut several foods at the same time, you won't know for sure which one may be causing your symptoms.

    Build a Diet That Works for You

    These tips can help you come up with your own healthy new meal plan:

    Limit highly refined foods. These foods lose some important nutrients in the process of making them. They fill you up but don't give you the fiber, vitamins, and minerals you need. Think twice before you eat:

    • White bread
    • White rice
    • Chips
    • Cookies and pastries

    Boost fiber. Fiber makes stool easier to pass. It helps many people with IBS-C symptoms, but not everyone.

    Too little roughage in your diet can make it hard to have a bowel movement. The Academy of Nutrition and Dietetics recommends 25 grams of fiber for women and 38 grams for men each day. People over age 50 may need a little less fiber (21 grams for women and 30 grams for men).

    You can get fiber in:

    • Whole-grain bread and cereals
    • Fruits
    • Vegetables
    • Beans

    Don't shock your system with a sudden increase of fiber, though. Your body will need time to get used to it, so add a little each day. Too much at once may make you feel worse.

    Try increasing your intake by 2 grams to 3 grams per day. For example, if you normally eat 5 grams of fiber, try getting 8 grams on your first day and go from there. If it helps, stick with it until you're getting as much as experts recommend.
