Constipation refers to symptoms such as reduced frequency of bowel movements, reduced stool volume, dry stool, and straining to pass stool, etc. Chronic constipation refers to the duration of the disease for more than 6 months. Some patients need to use hand assistance or help from others to pass stool, and the quality of life and mental and psychological condition of such patients are significantly affected. In severe cases, it can cause intestinal obstruction, bloating, abdominal pain, nausea, vomiting and other symptoms, requiring emergency hospital visits. The prevalence of constipation increases significantly with age, and women are more likely to suffer from constipation than men. In diseases such as acute myocardial infarction and cerebrovascular accidents, straining to defecate can even lead to sudden death. Factors leading to constipation are: 1, diabetes, hypothyroidism, spinal cord injury, Parkinson’s disease and other systemic diseases. 2, tumors, chronic inflammation, intestinal lumen stricture, intestinal obstruction and other organic diseases of the intestinal tract. 3, functional constipation, functional defecation disorders, irritable bowel syndrome and other functional diseases. 4, antihypertensive drugs (calcium antagonists), anticonvulsants, psychotropic drugs and other drug factors. Constipation is also associated with mental tension, anxiety, fatigue, etc., and with long-term spicy, dry-fried, fried, high-protein, high-fat diet, female smoking, low body mass index, etc. Patients may have intestinal flora dysbiosis, and the combination of Chinese and Western medicine to regulate intestinal flora can improve patients’ symptoms to a great extent. Patients with constipation need to be seen early to exclude constipation due to colorectal cancer, diabetes, hypothyroidism and other diseases. Patients need to adjust their diet, increase the intake of dietary fiber, drink more water, exercise moderately, and avoid holding the stool for a long time. Long-term abuse of laxatives, especially Chinese medicines containing rhubarb and aloe vera and some detoxification teas, may cause colonic melanosis, colon polyps and increase the risk of colorectal cancer. Functional constipation, commonly known as constipation without organic disease, can be detected through intestinal dynamics examination, whether the patient has slow intestinal peristalsis, constriction of the anal opening during defecation (paradoxical contraction), etc. For patients with slow intestinal peristalsis, intestinal dynamics drugs and drugs to regulate intestinal flora can be taken; for patients with constriction of the anal opening during defecation, biofeedback therapy is recommended, through the correction of defecation movements, together with the use of laxative drugs. For patients with constriction at the anal opening during defecation, biofeedback therapy is recommended to achieve better therapeutic effects by correcting the defecation movement and using laxative drugs.
