1, adjust the diet: avoid partial diet, increase water and crude fiber content in food intake, if necessary, add some agar, using their water absorption, so that the intestinal contents swell and increase, thus promoting intestinal peristalsis conducive to defecation. 2, exercise therapy: appropriate physical exercise according to physical fitness, less sitting and more walking, slow walking for 20 minutes after meals, in order to strengthen the body to enhance appetite, improve the contraction of the auxiliary muscle of defecation. Patients who need absolute bed rest or have poor limb movement should passively move their limbs every day to promote intestinal peristalsis and prevent the occurrence of constipation.

Therefore, patients should learn to self-regulate, reasonably relax themselves, relieve stress, in order to reduce the chance of constipation. 5, drug treatment: (1) permeability laxative: with high osmotic characteristics, after oral intake in the intestine to form a hypertonic state to absorb water, and prevent the intestine from absorbing water, resulting in an increase in the volume of intestinal contents, promote intestinal peristalsis, causing defecation. The advantages of these drugs are reliable efficacy and low side effects. Commonly used clinically for polyethylene glycol and lactulose, followed by salt laxatives, such as magnesium sulfate. (2) stimulant laxatives: is the most used drugs for chronic constipation in China, such drugs stimulate the intestinal mucosa and muscle intestinal nerve to promote intestinal peristalsis, propulsion movement, at the same time, also make the intestinal mucosa water and electrolyte secretion increase so that the stool becomes thin, soft.

(4) cumulative laxatives: these drugs are mainly preparations containing cellulose and oxytocin, which are not absorbed in the intestine but will absorb water, increase the volume of stool to stimulate intestinal peristalsis, and are fermented by intestinal bacteria in the colon to further increase intestinal osmotic pressure, prevent water from being absorbed and stimulate intestinal peristalsis to achieve diarrheal effects. (5) Microecological agents: These drugs mainly contain bifidobacteria, lactobacilli and other intestinal probiotics that can lower the pH in the intestinal cavity, promote intestinal peristalsis, reduce the absorption of harmful substances in the intestine, soften the stool and facilitate defecation. (6) other drugs: cisapride, mosapride and etopride and tegaserod, of which tegaserod has the best efficacy, but the U.S. FDA believes that the drug increases the occurrence of cardiovascular events and recommends caution.
