Have you ever experienced severe pain during a bowel movement and blood on the toilet paper? Many of you have experienced this pain more than once, when you feel a sudden tearing pain in your anus during a bowel movement. This is the result of anal fissure. Generally, it is caused by too coarse stool which can tear the skin below the dentate line at the exit of the anus when it is discharged. As mentioned earlier, the anus below the dentate line has somatic nerves that pass through it and are sensitive to pain, so when there is trauma here, the patient will feel a lot of pain. This is the most likely case of anal fissure, especially in young women with constipation who are overwhelmingly anal fissures, and if treated early and properly, can be treated without forming ulcers. Once the anus is injured, the wound expands a little each time a dry, hard stool is discharged, and the pain is so intense that it makes people weep. Therefore, many people are afraid to go to the toilet, but at this time, if forced not to defecate, constipation will become more and more serious, which will aggravate the anal fissure, the pain will be more intense, and further hate going to the toilet, which creates a vicious circle. Compared to pain, bleeding from anal fissures is relatively small, at most, there is blood on the stool paper or a small amount of blood drips after the stool, but when combined with internal hemorrhoids, bleeding increases. Anal fissures are more common in women, and because women are shy about going to the hospital, hospital statistics are higher for men than women. In reality, however, hemorrhoids and fistulas are more common in men, while anal fissures are more common in women. Early anal fissures can be easily cured by adjusting bowel movements and keeping the perianal area locally clean. Repeated constipation can cause the initial anal fissure to develop into an anal fissure, but it can still be cured at home by paying attention to preventing constipation, resting quietly after defecation, and keeping the area warm. Anal fissure is a small wound in the anus, similar to a knife wound, with little bleeding, mostly blood on hand paper and a vertical streak of blood attached to the stool strip or a small amount of blood dripping after a bowel movement. When such a condition first appears, even without special treatment, it can be cured in as little as two or three days or as long as a week. However, when constipation persists and the wound is repeatedly opened, the wound cannot be kept clean, and when it is not wiped clean due to painful stool, the wound can easily become infected, and it is difficult to heal after a long time. A typical anal fissure is very painful every time you have a bowel movement, but it can be treated completely at home. The first treatment is to soften the stool, drink more water, and eat more fiber-rich foods. Secondly, frequent showers and sitz baths are used to keep the wound clean and warm. Finally, suppositories are inserted in the anus. Also people with dry stools often have fissures in the same location, and care should be taken to continue softening the stool after healing. Anal fissures that occur repeatedly can cause fissures to fibrosis and contract, resulting in the formation of old anal fissures, leading to severe narrowing of the anus, a condition that can cause anal fissures to open even if the stool is not hard, further worsening anal fissures and forming a vicious circle. To cut off the vicious circle, inpatient surgery is necessary to eradicate the condition of long-term bowel irregularities. The prevention of anal fissures 1, prevention and control of anal fissures softening stool is most important, you can not just eat easily digestible food, should drink more water, eat more fiber-rich food. Such as: oranges, apples, kelp, taro, carrots, etc. 2, baths, sitz baths to keep the affected area clean.
