The experts at Chengdu Anorectal Specialist Hospital introduced that according to clinical statistics, the occurrence of anal fissures in female patients is much higher than in men, so why are women prone to anal fissures? The essential difference between women and men is the difference in physiological structure, and the special physiological structure of women can lead to deviations in the incidence of many diseases. Why are women prone to anal fissures? Experts say that because of the special physiological structure of women, it can easily lead to infection affecting anal fissures, and habits such as natural inactivity, snacking, and picky eating can easily cause constipation triggering anal fissures. The causes of anal fissures are generally due to mechanical irritation and inflammatory changes in the skin and blood vessels, but more mainly due to the factors of anatomical location. The posterior and anterior parts of the anal canal are not as strong as the two sides and can be easily damaged. Hard fecal pieces can tear the anal skin, causing compound infections that do not heal over time. There are also the following reasons for anal fissures in women: 1. After pregnancy, the activity is reduced, intestinal peristalsis is weakened, it is easy to produce constipation, dry and hard feces easily rubbed anal canal skin caused by local infection. 2, a special period triggered by anal fissure: some unmarried women are also more likely to suffer from anal fissure, especially during menstruation is more likely to aggravate, may be menstruation is not good rest and attention to menstrual hygiene, causing local inflammation of the anus, resulting in anal fissure. 3, local infection causes female anal fissures: compared to men, women are better “static” and bad “mobile”, especially young women, after pregnancy is correspondingly reduced, thus causing the intestinal peristalsis is weakened, very easy to produce constipation. After constipation, the dry and hard fecal mass is easy to rub the skin of the anal canal causing local infection, which can easily cause anal fissures to occur.
