What causes anal fistula?

Many people do not fully understand what causes anal fistula. Its pathological cause is mainly due to some anorectal and pancreatic cysts, and some anorectal diseases, which can also lead to such diseases. At the same time, purulent infections and some specific infections also have a greater impact on some external anorectal diseases. Its diagnosis and examination are also critical in life. Its onset is prone to some other types of tissue lesions in the anal canal.

The main symptoms and signs of anal fistula in daily life. It is pain and some common skin thickening and redness. How to treat in daily life and some preventive care are very important. In terms of preventive care, we must actively prevent and treat constipation and diarrhea.

There are two major types of anorectal abscesses: one is related to the anal glands and anal fistulas, called primary acute anal gland intermuscular fistula abscess, referred to as fistula abscess, which is more common; the other is unrelated to the anal glands and anal fistulas, called acute non-anal gland non-fistula abscess, referred to as non-fistula abscess, which is less common; anal fistulas mostly develop from the former.

Anal fistula is mostly caused by general purulent infection, and a few are caused by specific infections, such as tuberculosis, Crohn's disease, and ulcerative colitis.

Anal fistula can also be caused by secondary infection of rectal and anal canal trauma, and malignant tumors of the rectum and anal canal can also rupture into fistulas, but both are rare and are significantly different from general purulent anal fistulas.

Some people speculate that the influence of sex hormones is the main cause of anal fistula. During puberty, the body's own sex hormones begin to become active, and then some sebaceous glands, especially the anal glands, begin to develop and proliferate, with the proliferation being more obvious in males than in females. Due to the vigorous secretion of the anal glands, if the anal glands are not secreted smoothly or the anal gland ducts are blocked, they are prone to infection and cause anal gland inflammation. This can explain why the incidence of anal fistula is higher in young and middle-aged men. The anal gland ducts of women are straighter and less curved than those of men, so the secretions are not easily accumulated, so the incidence of anal fistula in women is lower. As people age, the anal glands and other sebaceous glands generally atrophy, and thus anal fistulas are rare in the elderly.

The above is how anal fistula is caused. Timely treatment of some other types of anorectal diseases and timely treatment of some diseases caused by perianal abscesses are necessary. It is necessary to insist on medication treatment. In terms of preventive care, it is necessary to actively prevent and treat constipation and diarrhea. At the same time, if you feel any anal discomfort, you should go to the hospital for examination in time.
