Constipation

Constipation occurs when bowel movements become difficult or less frequent. The normal length of time between bowel movements ranges widely from person to person. Some people have bowel movements three times a day; others, only one or two times a week. Going longer than three days without a bowel movement is too long. After three days, the stool or feces become harder and more difficult to pass.

There are numerous causes of constipation including diseases of the digestive system and side effects of medications, but for most people, a diet low in fiber may be the cause.
