Constipation is a common and complex clinical symptom rather than a disease, mainly referring to reduced frequency of bowel movements, reduced stool volume, dry stool, and straining to defecate. Symptomatic constipation can be diagnosed when two or more of the above symptoms are present at the same time. Constipation is usually characterized by a decrease in the frequency of bowel movements, usually once every 2~3 days or more (or <3 times per week). The results of a survey on a group of healthy people showed that the bowel habits were mostly 1-2 times a day or 1-2 times a day (60%), and the stools were mostly formed or soft; a few healthy people had up to 3 times a day (30%) or once every 3 days (10%), and the stools were semi-formed or bologna-like hard stools. Therefore, it is necessary to make a judgment of constipation by combining the nature of the stool, my usual bowel habits and the difficulty of defecation. If it is more than 6 months, it is chronic constipation. 1, classification 1, slow transmission type constipation is due to the contraction of the intestinal movement is weakened, so that the movement of feces from the cecum to the rectum slowed, or due to the uncoordinated movement of the left hemicolectomy caused. Most common in young women, occurring around puberty, characterized by reduced frequency of bowel movements (less than 1 bowel movement per week), less bowel movement, hard stool, and thus difficult to defecate; no stool or hard stool palpated during anorectal examination, while the contraction of the external anal sphincter and forceful defecation function is normal; prolonged total gastrointestinal or colonic transmission time; lack of evidence of outlet obstruction type, such as balloon expulsion test and anorectal manometry Normal. Non-surgical treatment methods such as increased dietary fiber intake with osmotic laxatives are ineffective. Diabetes, scleroderma combined constipation and drug-induced constipation are mostly slow transmission type. 2, exit obstruction type constipation is due to muscle incoordination in the abdomen, anorectum and pelvic floor resulting in fecal impaction. It is especially common in elderly patients, many of whom are ineffective with conventional medical treatment. The outlet obstruction type may have the following manifestations: straining to pass stool, a feeling of incompleteness or falling, a small amount of stool, a desire to pass stool or a lack of desire to pass stool; anorectal examination shows a lot of muddy stool in the rectum, and the external anal sphincter may contract paradoxically during straining to pass stool; total gastrointestinal or colonic transit time shows normal, and most markers may be retained in the rectum; anorectal manometry shows paradoxical contraction of the external anal sphincter during straining to pass stool contraction or abnormal sensory threshold of the rectal wall, etc. Many patients with outlet obstruction constipation also have a combination of slow transmission constipation. With the change of people's dietary structure and the influence of psychological and social factors, the incidence of constipation has a tendency to increase. The prevalence of constipation in the population is as high as 27%, but only a small percentage of constipated people will seek medical attention. Constipation can affect people of all ages. It is more common in women than in men, and in older than in younger and older adults. Because of the high prevalence and complex causes of constipation, patients often have a lot of distress, and constipation can affect the quality of life when severe. Constipation is often manifested as: less bowel movement, less bowel movements; difficult and laborious defecation; poor defecation; dry and hard stools, unclean feeling of defecation; constipation accompanied by abdominal pain or abdominal discomfort. Some patients also have insomnia, irritability, dreaminess, depression, anxiety and other mental and psychological disorders. The "alarm" signs of constipation include blood in stool, anemia, weight loss, fever, black stool, abdominal pain, and family history of tumor. If alarm signs appear, you should immediately go to the hospital for further examination. As constipation is a more common symptom, the symptoms vary in severity, most people often do not pay special attention to constipation is not a disease, do not need treatment, but in fact, constipation is very harmful. 1, constipation in some diseases such as colon cancer, hepatic encephalopathy, breast disease, the occurrence of premature dementia, there are many studies reported. 2, constipation in acute myocardial infarction, cerebrovascular accident patients can lead to life accidents, there are many tragic cases to alert us. 3, some constipation and anorectal diseases, such as hemorrhoids, anal fissures, etc. have a close relationship. Therefore, early prevention and reasonable treatment of constipation will greatly reduce the serious consequences of constipation, improve the quality of life, and reduce the burden on society and families. V. Disease treatment Constipation patients need to be treated according to the severity, cause and type of constipation, using comprehensive treatment, including general life treatment, drug therapy, biofeedback training and surgical treatment to restore normal defecation physiology. Emphasis should be placed on lifestyle treatment, strengthening patient education, adopting reasonable dietary habits, such as increasing dietary fiber content, increasing water intake to enhance stimulation of the colon, and developing good defecation habits, such as morning defecation, timely defecation when there is an urge to defecate, avoiding straining to defecate, and at the same time, activities should be increased. During treatment, attention should be paid to the removal of excessive fecal accumulation in the distal rectum; positive attitude adjustment is needed, all of which are extremely important to obtain effective treatment.
