Constipation : Constipation refers to infrequent or hard stools, or difficulty passing stools. More specifically, constipation may involve pain during the passage of a bowel movement, the inability to pass a bowel movement after straining or pushing for more than 10 minutes, or no bowel movements after more than 3 days.
Treatment
Laxatives like aloe, cascara, senna compounds, bisacodyl, and castor oil. Bisacodyl (Dulcolax, Correctol) is available OTC in oral pill form and as a suppository or enema. The oral form takes 6 to 10 hours to work. Bisacodyl is commonly used in cleansing the colon for colonoscopies,barium enemas, and intestinal surgeries. While effective for occasional constipation, bisacodyl should not be taken for more than a week, and a doctor should supervise repeated use.
Other stimulant laxatives include senna (Ex-Lax, Senokot), cascara sagrada (Nature's Remedy), and casanthranol. These laxatives are converted by the bacteria in the colon into active compounds which then stimulate the contraction of colon muscles. After taking these products orally, bowel movements occur after 8 to 24 hours. Prolonged, chronic use of these laxatives can cause the lining of the colon to become darker than normal (melanosis coli) due to the accumulation of a pigment (melanin).
Castor oil (an ingredient of Purge Concentrate) is a liquid stimulant laxative that works in the small intestine. It causes the accumulation of fluid in the small intestine and promotes evacuation of the bowels. Castor oil should not be taken with food, although juice or other flavored liquids can help hide its unpleasant taste.
