Bowel Function Disorders

Conditions and Treatments

Common digestive problems, such as diarrhea or constipation, interrupt normal bowel functions and cause discomfort.

• Diarrhea can be described as an abnormal increase in the frequency, volume or liquidity of your stools. The condition usually lasts a few hours to a couple of days. Diarrhea is typically associated with abdominal cramps. The most common causes of the condition are viruses, bacteria and parasites.

• Constipation -- the infrequent and difficult passage of stools -- is the most common digestive complaint in the United States, resulting in approximately two million doctor visits annually. Women, especially those who are pregnant, and adults aged 65 and older are most commonly affected. Virtually everyone experiences an occasional bout of constipation that resolves itself with dietary changes and time. Although uncomfortable, it is usually not dangerous. However, it can lead to other problems such as hemorrhoids or signal an underlying health condition.
