In our daily life we find that young women suffer from anal fissures in far greater numbers than men. This is due to the characteristics of the anatomical structure of the perineum of the anus in women. The vagina is in front of the female anus, and the muscles nearby are weak, plus the physiological peculiarities of women, such as menstruation, pregnancy, especially excessive force during childbirth, or women’s menstrual blood loss, which can cause constipation, all of which can cause tears in the perineum and anal canal. For the above reasons, the following aspects of anal fissure prevention should be noted: 1, menstrual period: pay attention to menstrual hygiene, keep the perineum dry to avoid inflammation of the anal area; in addition, menstrual period, such as excessive blood loss, can cause a decrease in intestinal fluids, dry stool discharge difficulties, and the anal canal tears, so you can give appropriate drugs to supplement Qi and blood and laxative drugs to keep the stool smooth. 2, pregnancy and childbirth: when women are pregnant, due to increased abdominal pressure, venous reflux obstruction, coupled with high nutrient requirements during pregnancy, constipation and other conditions, can increase the strength of the tearing of the tissue around the anus when defecating. During delivery, attention should be paid to protecting the perineum and anal tissues to avoid tearing the anal canal tissues due to excessive force and anal fissures occur.
