What is constipation?

If you have constipation, you may have hard bowel movements (stools) that are difficult to pass and you may feel unable to fully empty your bowel. Constipation may cause abdominal pain and bloating in some people. In general, you are not constipated if your stools are soft and pass easily without strain or discomfort.

Should I have a bowel movement every day?

It is not true that everyone must have a bowel movement daily. For some people, it is normal to have three bowel movements every day. For others, it is normal to have three bowel movements every week.

What causes constipation?

There are many causes of constipation, including:

When should I see a doctor?

You should see a doctor if:

How can my diet help constipation?

Many people with constipation can benefit from a high-fibre diet and lots of fluids. High-fibre foods help to hold water in the stools, keeping them soft. When you eat more high-fibre foods, remember also to drink more fluids. For example, 9 cups for women and 12 cups for men each day.

Increase fibre in your diet slowly. A sudden increase in fibre may cause cramps and/or gas.

A High Fibre Diet has Other Benefits

A high fibre diet may help control diabetes and high blood cholesterol levels. Many fibre-rich foods such as legumes, whole grains, vegetables and fruit may help protect you from cancer.

Which foods are high in fibre?

Good high-fibre food choices include:

Other Tips:

What about prunes?

If a high-fibre, high-fluid diet does not relieve your constipation, try eating prunes occasionally. Prunes are a good source of fibre, and they also contain a substance that is a natural laxative.

You may also try Fruit Lax occasionally. The recipe is as follows:

Combine 1 cup prunes, 1 cup raisins, 1 cup dates. Soak overnight in a mixture of 1/2 cup orange juice and 2/3 cup prune juice. Blend in blender. 1 cup of wheat bran can be added.

Fruit lax will keep for two weeks in the fridge or can be frozen. It can be used as a spread on toast, or mixed into hot cereal or plain yogurt.

What about laxatives?

Laxatives should only be used as a last resort for constipation. Try diet and lifestyle changes first. If your constipation does not get better, speak with your doctor about using a laxative. The first choice of laxative is generally a bulk forming laxative with psyllium. Long-term use of other laxatives can result in having to rely on them, or other undesirable effects.
