What causes frequent difficulty in defecation?

Hello! Dysdefecation is clinically called constipation. The reasons for the difficulty in defecation are:

1, dietary factors

Some people eat too little, the food is too fine and fine, the cellulose and water in the food are insufficient, which can not stimulate the intestine to a certain extent, the intestine peristalsis is slow, the food residue can not be pushed to the rectum in time, the stay time in the intestine is prolonged, and the feces are dried because of excessive water absorption. After the fecal residue enters the rectum, it cannot form enough pressure to stimulate nerve sensory cells to produce defecation reflex and cause constipation.

2. Insufficient 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 descending 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 decreased and the defecation motivation is insufficient, so that the feces are not discharged cleanly, the feces remain and it is difficult to defecate.

3. Delaying defecation time

Some people regard defecation as unimportant, but it can be early or late, ignoring the habit of regular defecation; Or because of busy work, nervous mood, travel life, etc. The time of defecation is delayed, so that the feces that have reached the rectum return to the colon; Or because of anal diseases such as anal fissure and hemorrhoids, they are afraid of pain, bleeding and defecation. All these may slow down the response of nerve cells on the rectal wall to the oppressive feeling caused by feces entering the rectum, prolong the residence time of feces in the rectum without causing defecation feeling, and form habitual defecation difficulty.

4. Too much water loss

Excessive sweating, vomiting, diarrhea, blood loss and fever can cause dehydration and compensatory dry stool.

5. 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.

6. Colorectal lesions

Diseases such as allergic colitis, diverticulitis of large intestine, Hirschsprung's disease, etc. can cause large intestine spasm and dyskinesia, which makes it difficult to defecate due to poor passage of feces.

7. Difficulty in defecation caused by drug influence

Take calcium carbonate, aluminum hydroxide, atropine, propofol, morphine, phenethylpiperidine, bismuth carbonate, etc. And lead, arsenic, mercury, phosphorus and other metal poisoning will lead to difficulty in defecation. Long-term abuse of laxatives reduces the stress of nerve sensory cells in intestinal wall. Even if there is enough feces in the intestine, it can't produce normal peristalsis and defecation reflex, which leads to intractable defecation difficulty.

8. Dysdefecation caused by 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.

I hope it helps you!
