What is constipation related to?
1, lack of defecation motivation. When defecating, we need not only the relaxation of anal sphincter and the upward and outward pulling of levator ani, but also the downward movement of diaphragm, the contraction of abdominal muscles and the strength of holding your breath to push out feces. Old and weak, bedridden after a long illness, postpartum, etc. Because the contractility of diaphragm, abdominal muscle and anal sphincter is weakened, the abdominal pressure is reduced, and the defecation motivation is insufficient, so that feces are not discharged cleanly, feces remain, and constipation occurs.
2, the influence of drugs, long-term use of some drugs that stimulate the stomach may also lead to constipation.
3, delay the stool time. Some people regard defecation as an unimportant thing and can do it in the morning and evening, ignoring the habit of regular defecation, which slows down the pressure of nerve cells on the rectal wall on feces entering the rectum, prolongs the stay time of feces in the rectum without causing defecation feeling, and forms habitual defecation difficulties.
4. Dietary factors. Some people eat too little, the food is too fine and fine, and the cellulose and water in the food are insufficient, which can not stimulate the intestines to a certain extent. In this case, it is necessary to eat more coarse grains and grains with fiber.
5. Mental factors. Strong mental stimulation, panic, emotional tension, anxiety or high concentration on a certain job will all cause difficulty in defecation. In addition, nervous system disorder, endocrine disorder, vitamin deficiency and so on. It can also cause difficulty in defecation.
6, large intestine lesions. Allergic colitis, diverticulitis of large intestine, Hirschsprung's disease, etc. It can cause large intestine spasm and dyskinesia, which makes it difficult to defecate because of poor passage of feces. This kind of disease needs treatment, and if it is not treated, it is likely to become cancerous.
7. Organic obstruction. When there is intestinal stenosis or compression outside the intestine, such as benign and malignant tumors of the intestine, intestinal stenosis caused by chronic inflammation, rectal spasm and stenosis caused by Hirschsprung's disease, postoperative intestinal adhesion, partial intestinal obstruction, etc. Or huge tumors in abdominal cavity, such as ovarian cyst, hysteromyoma, pregnancy, ascites and large intestine compression. It is difficult to control the passage of feces and stay in the intestine for too long, which makes defecation difficult.
