The treatment principle is to carry out comprehensive treatment according to the severity, etiology and type of constipation to restore normal defecation habits and defecation physiology. 1.General treatment Strengthen education on the physiology of defecation, establish reasonable dietary habits (such as increasing dietary fiber content and water intake) and adhere to good defecation habits, and at the same time, increase activities. 2.Medication Select appropriate laxative drugs. The choice of drugs should be less toxic, side effects and drug dependence as the principle, often selected such as bulking agents (such as wheat bran, O-cheese, etc.) and osmotic laxatives (such as Fosone, Dulcolax). Randomized controlled observation of the application of Fosone in the treatment of functional constipation showed that it was effective in increasing the number of bowel movements and improving stool properties. For slow-transmission constipation, prokinetic agents such as cisapride or mosapride can be added. It should be noted that for patients with chronic constipation, long-term application or abuse of stimulant laxatives should be avoided. A variety of proprietary Chinese medicines have laxative effects, but it should be noted that when taking proprietary Chinese medicines for chronic constipation over a long period of time, attention should be paid to the ingredients within them and their side effects. For patients with fecal impaction, clean enema once or combine with short-term use of stimulant laxatives to release the impaction. After decongestion, use bulking agents or osmotic drugs to keep the bowel movement open. Curettage and glycerin suppositories have the effect of softening stool and stimulating defecation. Compound carrageenan can be effective in the treatment of constipation of hemorrhoidal origin. 3, psychotherapy and biofeedback moderate and severe constipation patients often have anxiety and even depression and other psychological factors or disorders, should be cognitive therapy, so that patients eliminate tension. Biofeedback therapy is suitable for functional outlet obstruction type constipation. 4, surgical treatment If the effect is still small after strict non-surgical treatment, and various special examinations show that there is a clear pathological anatomy and conclusive functional abnormal site, surgical treatment can be considered. Indications for surgical procedures include secondary megacolon, partial colonic redundancy, colonic weakness, severe anterior rectal distention, endorectal overlap, and intra-rectal mucosal prolapse. However, attention should be paid to the presence of severe psychological disorders, the presence of digestive tract abnormalities other than the colon, and the need for preoperative prediction of outcome.
