Constipation is a very common symptom. It affects virtually everyone at some point in their lives. Occasional constipation may result from many factors such as dietary changes or inactivity and will generally respond to simple lifestyle measures. However, constipation that is chronic or recurrent may require a more concerted effort to diagnose and treat. Those suffering persistent constipation should see a physician to plan investigation and treatment.
In surveys, as many as 25% say they are constipated, and using medical criteria, up to 17% have constipation.[1,2] A systematic review of a number of studies based on both self-reported and medical criteria conservatively estimates that constipation affects nearly 15% of the North American population, or 42 million persons in the U.S. alone.[1]
Many with constipation do not seek help and their symptoms are probably mild or transient. Nevertheless, many do see doctors for constipation and for them it can be very troubling.
Constipation affects everyone, although it becomes more common as people age; women report constipation two to three times more often than men.[1] Hundreds of over-the-counter laxatives are purchased annually to treat constipation. Surprisingly, there is no definition of constipation that applies to all persons. For some, satisfactory treatment is often elusive. But there is hope; find out more on this web site.
