Eating, Diet, & Nutrition for Constipation

How can my diet help prevent and relieve constipation?

You can drink water and other fluids, such as fruit and vegetable juices and clear soups, to help the fiber in your diet work better. This change should make your stools more normal and regular. Ask your doctor about how much you should drink each day based on your health and activity level and where you live.

Depending on their age and sex, adults should get 22 to 34 grams of fiber a day.3 Older adults sometimes don’t get enough fiber in their diets, because they may lose interest in food. If you are older and have lost interest in food, talk with your doctor if

  • food doesn’t taste the same as it once did
  • you don’t feel hungry as often
  • you don’t want to cook
  • you have problems chewing or swallowing

Talk with your doctor to plan a diet with the right amount of fiber for you. Be sure to add fiber to your diet a little at a time so that your body gets used to the change.

Use this table as a tool to help replace less healthy foods with foods that have fiber.
