Constipation is a group of clinical syndromes that manifest with difficulty in defecation and a marked reduction in the number of bowel movements. The main features are as follows: (1) The number of bowel movements is significantly delayed and reduced, usually once every 3-5 days or longer, and the standard concept is to have less than 2 bowel movements per week. This is when the stool mass is relatively dry. (2) Difficulty in defecation, mainly manifested by the effort of defecation, each time defecation requires a long time to use force to be unable to solve, even when defecating thin and soft stools. There is a sense of incomplete defecation, requiring repeated defecation. Some people need medication or hand-assisted evacuation. When the above symptoms persist for a long time, serious psychological disorders may occur, manifesting as depression and neurosis. The causes of constipation are very complex. Mental factors are the first cause of constipation, and patients with severe constipation will almost always show depression or mental emotional performance; secondly, various serious medical diseases, such as cardiovascular and cerebrovascular lesions, diabetes mellitus, chronic renal insufficiency, etc. Patients with these geriatric diseases will have serious endocrine disorders, or long-term use of various drugs, etc., resulting in changes in intestinal function; the elderly, due to metabolic After decreasing, the pelvic floor muscle support ability decreases, leading to the relaxation of the pelvic floor, down off, etc.; after long-term abnormal bowel movements began to use some laxatives on their own, or young people are keen to lose weight, some diet pills almost all contain a variety of improper laxatives, due to the general use of laxatives, these irritating laxatives, stimulating the intestinal wall gradually make the intestinal function more decompensated, leading to a decline in intestinal dynamics. Women’s pelvic floor is weaker than men’s, and the rectum is preceded by the vaginal wall, and the rectum can easily protrude abnormally to this weak part, and because women have pregnancy and childbirth, resulting in injuries to the pelvic floor. All these reasons are the basic reasons for the occurrence of constipation. Nowadays, through some examination methods, it is found that whatever the cause of constipation is, it is caused by changes in the function and structure of the colorectum and pelvic floor.
