The frequency of bowel movements among healthy people varies from three movements a day to three a week. Individuals must determine what is normal. As a rule, constipation should be suspected if more than three days pass between bowel movements or if there is difficulty or pain when passing a hardened stool. Most people experience occasional short bouts of constipation, but if a laxative is necessary for longer than three weeks, check with a doctor.

Doctors agree that prevention is the best approach to constipation. While there is no way to ensure never experiencing constipation, the following guidelines should help:

• Know what is normal and do not rely unnecessarily on laxatives.
• Eat a well-balanced diet that includes unprocessed bran, whole-wheat grains, fresh fruits and vegetables.
• Drink plenty of fluids.
• Exercise regularly.
• Set aside time after breakfast or dinner for undisturbed visits to the toilet.
• Don’t ignore the urge to defecate.
• Whenever there is a significant or prolonged change in bowel habits, check with a doctor.
