1, bad bowel habits: toilet squatting position reading books and newspapers, resulting in squatting and bowel time prolonged, easy to cause blood stasis in the anal cecum and cause disease. Excessive force when defecating, some people do not care whether the feeling of defecation is strong, blindly and non-stop fierce struggle, can only make the cecum, anus and pelvic floor muscles to increase the unnecessary burden and local stasis, resulting in the occurrence and spread of disease.

2, stool abnormality: diarrhea and constipation are important causes of nevus pale. Constipation is the biggest cause of the disease, long-term retention of toxic substances in the cecum can not only trigger cecum cancer, and fecal matter accumulation, affecting blood circulation.

3, chronic diseases: such as long-term nutrition is not good, physical weakness, resulting in anal sphincter relaxation and weakness. Long-term chronic bronchitis, emphysema, caused by coughing and wheezing, abdominal pressure rises, pelvic stasis. Chronic hepatitis, hepatic cirrhosis, diarrhea, colitis, etc. are the causative factors for the occurrence of anal and intestinal diseases.

4, dietary reasons: food quality of fine and coarse, changes in the type of vegetables and the amount of increase or decrease in the amount of protein, fat, starch, fiber and other content of the amount of water intake situation, can directly affect the composition of feces, resulting in anal appendix disease.

5, physiological reasons: colon, cecum for the transport of food residues, feces storage of the main organs, and food decomposition and absorption of the body, the residue is often with a large number of harmful substances, long-term retention in the colon and cecum, can lead to tumors.

6, anatomical reasons: the anal venous system and vena cava system in the lower end of the cecum, there are many venous plexus and anastomotic branches, the venous wall is weak, the resistance to the pressure is reduced, the cecum submucosal tissue is lax, which is conducive to the expansion of the veins varicose deformation, hemorrhoids are easily formed.

7, abnormal embryonic development causes: abnormal development process, can occur in the anal cecum part of many congenital anorectal diseases, such as congenital anus, congenital cecal-vaginal fistula, congenital megacolon.

8, genetic causes: venous wall congenital weakness, resistance to reduce, can not tolerate intravascular pressure, and thus gradually expand.

When people stand or sit, the anorectum is located in the lower part of the body, due to gravity and other organs of the pressure, affecting the blood return, the veins are prone to expansion and flexion, so often standing or sitting people are prone to hemorrhoids.

The formation of hemorrhoids can be induced by a high level of frailty, a long period of illness, or a weak anal sphincter, overwork, etc.

This is the first time that a person has ever had a hemorrhoid in his or her life.
