Anorectal disease etiology

Internal cause:
1, normal human anatomy factors are particularly easy to form hemorrhoids.
2, physiological factors: colon and rectum are important organs to transport food residues, and after the food is decomposed and absorbed in the body, the residue often contains a large number of harmful substances, long-term retention in the colon and rectum, can induce tumors.
3, genetic factors: because of genetic defects, can produce multiple colon polyps, P-J syndrome (melanin spot - colon polyposis) and other hereditary anorectal diseases.
4. Congenital diseases.
External cause:
1, bad bowel habits: on the toilet, squatting, reading, reading newspapers, resulting in squatting and defecation prolonged, easy to cause blood stasis in the anus and rectum and induce diseases. When smoking on the toilet, it can buffer the defecation reflex of the brain, and it is extremely easy to cause constipation. Defecation too hard, some people feel strong regardless of defecation, blindly slamming hard earned, can only make the anorectal and pelvic muscles to increase the burden of unnecessary and local blood stasis, lead to disease occurrence and development.
2 、 abnormal defecation: diarrhea and constipation are important pathogenic factors of anorectal diseases. Constipation is the biggest curse, long-term retention of toxic substances in the rectum, not only can cause rectal cancer, and fecal accumulation, affecting the blood circulation. The solution of the dried fecal block will cause great pressure on the anus, resulting in a series of pathological changes, such as blood stasis, swelling, swelling and fissure. Diarrhea is often the clinical manifestations of colonic disease, diarrhea can also make anus local infection opportunities, produce inflammatory external hemorrhoids, anal sinusitis, perianal abscess and other diseases.
3, diet factors: daily life, diet laws or diet varieties inevitably change, this is very natural. Such as food quality and quantity of forage, change the vegetable species or how much protein, fat, starch, cellulose content, water intake, can directly affect the composition of feces, caused by anorectal diseases. Long term drinking or eating spicy food, wine and spicy things can stimulate the gastrointestinal mucosa, causing blood vessels to dilate, colon dysfunction, anorectal disease incidence increased significantly. The census data shows that eating spicy the incidence rate was 61.6%, hi drinkers the incidence rate was 64.6%, were significantly higher than the incidence rate.
4, occupational factors: standing or sedentary for a long time. Due to upright or sitting posture, the anus and rectum live in the lower part of the human body, and the hemorrhoidal veins return poorly.
5, chronic diseases: such as long-term malnutrition, weak physique, causing anal sphincter relaxation weakness. Chronic suffering from chronic bronchitis and emphysema, caused by cough and abdominal pressure rising, pelvic congestion. Chronic hepatitis, cirrhosis, diarrhea and colitis are all the causes of anorectal diseases. Therefore, in the prevention, we should pay attention to the general state of the patient and take reasonable and effective preventive measures.
