  • Chronic Constipation: an Evidence-Based Review
    J Am Board Fam Med: first published as 10.3122/jabfm.2011.04.100272 on 7 July 2011. Downloaded from CLINICAL REVIEW Chronic Constipation: An Evidence-Based Review Lawrence Leung, MBBChir, FRACGP, FRCGP, Taylor Riutta, MD, Jyoti Kotecha, MPA, MRSC, and Walter Rosser MD, MRCGP, FCFP Background: Chronic constipation is a common condition seen in family practice among the elderly and women. There is no consensus regarding its exact definition, and it may be interpreted differently by physicians and patients. Physicians prescribe various treatments, and patients often adopt different over-the-counter remedies. Chronic constipation is either caused by slow colonic transit or pelvic floor dysfunction, and treatment differs accordingly. Methods: To update our knowledge of chronic constipation and its etiology and best-evidence treat- ment, information was synthesized from articles published in PubMed, EMBASE, and Cochrane Database of Systematic Reviews. Levels of evidence and recommendations were made according to the Strength of Recommendation taxonomy. Results: The standard advice of increasing dietary fibers, fluids, and exercise for relieving chronic constipation will only benefit patients with true deficiency. Biofeedback works best for constipation caused by pelvic floor dysfunction. Pharmacological agents increase bulk or water content in the bowel lumen or aim to stimulate bowel movements. Novel classes of compounds have emerged for treating chronic constipation, with promising clinical trial data. Finally, the link between senna abuse and colon cancer remains unsupported. Conclusions: Chronic constipation should be managed according to its etiology and guided by the best evidence-based treatment.(J Am Board Fam Med 2011;24:436–451.) copyright.

  • Saline Cathartics
    Saline Cathartics Saline cathartics or purgatives are agents that quicken and increase evacuation from the bowl. Laxatives are mild cathartics. Cathartics are used: to ease defecation in patients with painful hemorrhoids or other rectal disorders and to avoid excessive straining and concurrent increase in abdominal pressure in patients with hernias Or to avoid potentially hazardous rise in B.P. during defecation in patients with hypertension, cerebral coronary or other arterial disease Or to relieve acute constipation Or to remove solid material from intestinal tract prior to certain roentgenographic studies. Laxative should only be used for short term therapy as prolonged use may lead to loss of spontaneous bowl rhythm upon which normal evacuation depends, causing patient to become dependent on laxatives, the so called laxative effect. Constipation is the infrequent or difficult evacuation of the feces. It may be due to a person resisting the natural urge to defecate, causing the fecal material which remains in the colon to lose fluid and to become relatively dry and hard. Constipation can also be due to intestinal atony, intestinal spasm, emotions, drugs and diet. Many a time constipation can be helped by eating food such as natural laxatives or food with large roughages. Four types of laxatives are known: 1. Stimulants 2. Bulk forming 3. Emollient 4. Saline cathartics Stimulants act by local irritation on the intestinal tract which increase peristaltic activity. They include phenolphthalein, aloin, cascara extract, rhubarb extract, senna extract, podophyllin, castor oil, bisacodyl, calomel etc. Bulk forming laxatives are made from cellulose, sodium carboxyl methyl cellulose and karaya gum.
