Constipation facts

Constipation is defined medically as fewer than three stools per week and severe constipation as less than one stool per week. Constipation usually is caused by the slow movement of stool through the colon. There are many causes of constipation including medications, poor bowel habits, low fiber diets, abuse of laxatives, hormonal disorders, and diseases primarily of other parts of the body that also affect the colon. The two disorders limited to the colon that cause constipation are colonic inertia and pelvic floor dysfunction. High levels of estrogen and progesterone during pregnancy may cause constipation. Medical evaluation of constipation should be done when constipation is of sudden onset, severe, worsening, associated with other worrisome symptoms such as loss of weight, or is not responding to simple, safe treatments. Medical evaluation of constipation may include a history, physical examination, blood tests, abdominal X-rays, barium enema, colonic transit studies, defecography, anorectal motility studies, and colonic motility studies. The goal of therapy for constipation is one bowel movement every two to three days without straining. Treatment of constipation may include dietary fiber, non-stimulant laxatives, stimulant laxatives, enemas, suppositories, biofeedback training, and surgery. Stimulant laxatives, including herbal laxatives, should be used as a last resort because they may permanently damage the colon and worsen constipation.

What is constipation?

Constipation means different things to different people. For many people, it simply means infrequent stools. For others, however, constipation means hard stools, difficulty passing stools (straining), or a sense of incomplete emptying after a bowel movement. The cause of each of these symptoms of constipation vary, so the approach to each should be tailored to each specific person.

Constipation also can alternate with diarrhea. This pattern commonly occurs as part of the irritable bowel syndrome (IBS). At the extreme end of the constipation spectrum is fecal impaction, a condition in which stool hardens in the rectum and prevents the passage of any stool (although occasionally diarrhea may occur even with the obstruction).

The number of bowel movements generally decreases with age. Most adults have bowel movements between three and 21 times per week, and this would be considered normal. The most common pattern is one bowel movement a day, but this pattern is seen in less than half the people. Moreover, most people are irregular and do not have bowel movements every day or the same number of bowel movements each day.

Medically speaking, constipation usually is defined as fewer than three bowel movements per week. Severe constipation is defined as less than one bowel movement per week. There is no medical reason to have a bowel movement every day. Going without a bowel movement for two or three days does not cause physical discomfort, only mental distress for some people. Contrary to popular belief, there is no evidence that "toxins" accumulate when bowel movements are infrequent or that constipation leads to cancer.

It is important to distinguish acute (recent onset) constipation from chronic (long duration) constipation. Acute constipation requires urgent assessment because a serious medical illness may be the underlying cause (for example, tumors of the colon). Constipation also requires an immediate assessment if it is accompanied by worrisome symptoms such as rectal bleeding, abdominal pain and cramps, nausea and vomiting, and involuntary loss of weight. The evaluation of chronic constipation may not be urgent, particularly if simple measures bring relief.
