Symptom: Constipation

Constipation: Hardness of stool or difficulty or inability to pass feces.
Introduction: Constipation is a common symptom where a person has difficulty passing feces or unusually dry stool. Note that dry stool is medically considered within the spectrum of "constipation", although many people will use the term constipation only when stool dryness or hardness actually causes difficulty passing stool. Straining at stool is called "tenesmus"; see also bowel infrequency.

Constipation is common in children and older age, but can affect anyone. Since everyone has difficult bowel patterns, and not everyone passes one stool per day, exactly who qualifies for the diagnosis of "constipated" is not always clear. About 2% of the population suffers from chronic constipation. Various conditions can cause constipation ranging from poor diet, aging, pregnancy, irritable bowel syndrome, and numerous other underlying conditions for constipation. Constipation can also cause diarrhea leading to misdiagnosis. Various medications can cause constipation including overuse of laxatives that can cause a vicious cycle of constipation. Although constipation is not usually caused by a serious disease, professional medical advice is necessary to rule them out.
