Constipation in Adults

Constipation Overview

Constipation refers to a decrease in the frequency of bowel movements. For some people, it may mean difficulty in passing stools. A constipated stool is hard because it contains less water than normal. Constipation is a symptom, not a disease.

Generally, constipation is difficult to define clearly because as a symptom it varies from person to person.

  • The frequency of bowel movements also varies greatly, ranging from 3 movements per day to 3 per week. Generally, if your bowel has not opened for 3 successive days, the intestinal contents harden, and you may have difficulty or even pain during defecation.

Some people have an underlying fear that they will be "poisoned" by their own intestinal wastes (feces) if they retain the waste in their bodies for more than a certain length of time. None of this is true.
  • Older people are 5 times more likely than younger people to develop constipation. But experts believe that older people become too concerned with having a daily bowel movement and that constipation in this age group is overestimated.
