Various surveys report the incidence of constipation to range from 2 to 30%, with one large international survey pegging the number at 12% worldwide. The numbers encompass a wide range and probably reflect fundamental problems in the survey method itself. However, the bottom line is that constipation is a common condition that afflicts a substantial fraction of the population.

One explanation for why the statistics are so inconsistent is that constipation has historically been a poorly-defined condition. The poor definitions are due the fact that constipation varies quite a bit between patients. Frequency of bowel movements, time spent straining at the toilet and hardness of feces are but three examples of patient-reported symptoms that vary wildly from person-to-person. Some attempt has been made by both U.S. national agencies and private groups (such as the Rome Foundation) in unifying our definition of constipation. Nevertheless, diagnosis is made difficult by such variations.

The causes of constipation are also numerous. Certain poorly understood but well-defined chronic conditions such as irritable bowel syndrome can lead to constipation. As there is no treatment for the underlying condition, alleviation of symptoms is the only therapeutic route. Physiological and anatomical defects can also give rise to constipation. These include muscle or nerve damage from or sports-related injuries. Finally, a very broad class of patients have no identifiable cause: these patients have what is termed idiopathic constipation.

Often first line therapy for people diagnosed with chronic idiopathic constipation is introduction of high fiber into diet. Recent studies show that fiber and fluids are effective in only a small fraction of patients. Because of the ease and accessibility of high fiber treatment, it is quite popular with physicians and patients. Response is expected within two weeks, at which time both parties may decide whether the diagnosis and therapy were successful.

Other types of natural treatments include both lubricant laxatives and herbal supplements such as senna. Herbal and natural supplements are not always safe. The FDA has banned some natural supplements, namely aloe vera and cascara recently, for failure on the part of manufacturers to provide sufficient safety data. However, some other over-the-counter treatments remain available.

There are also a number of prescription-only constipation medications available. Some of these act as laxatives, whereas others are special compounds that modulate the functional properties of the gastrointestinal tract. In recent times, exciting therapies such as biofeedback have also risen to prominence. Expect treatments for constipation to advanced greatly in the next few years. - 30193
