Constipation does not occur overnight, and it is not reasonable to expect that constipation can be relieved overnight. 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.
Know what is normal and do not rely unnecessarily on laxatives. Drink plenty of fluids. 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.
