Constipation

Posted Jun 02 2009 4:39pm

Constipation is passage of small amounts of hard, dry bowel movements, usually fewer than three times a week. People who are constipated may find it difficult and painful to have a bowel movement. Other symptoms of constipation include feeling bloated, uncomfortable, and sluggish.

What are Some Common Misconceptions About Constipation?

Another common fallacy is that wastes stored in the body are absorbed and are dangerous to health or shorten the life span. These misconceptions have led to a marked overuse and abuse of laxatives.

Many people think they are constipated when, in fact, their bowel movements are regular.

For example, some people believe they are constipated, or irregular, if they do not have a bowel movement every day. However, there is no right number of daily or weekly bowel movements. Normal may be three times a day or three times a week depending on the person. In addition, some people naturally have firmer stools than others. At one time or another almost everyone gets constipated. Poor diet and lack of exercise are usually the causes. In most cases, constipation is temporary and not serious. Understanding causes, prevention, and treatment will help most people find relief.
