Some people suffer from severe anal fissures, and the pain at the anus during defecation is so great that they develop a sense of fear of cold sweat when they see the toilet. In order to avoid such pain, these people tend to adopt a diet to reduce the number of bowel movements, which is a highly undesirable treatment. Some patients with anal fissures often take self-righteous countermeasures without asking the doctor in order to reduce the pain, the result not only does not achieve the desired purpose, but also has a tendency to become more and more serious, which has to draw the attention of patients with anal fissures. –purposely delaying the normal time of defecation and reducing the frequency of defecation – resulting in feces staying in the large intestine for too long, water being completely absorbed, or fecal lumps forming a pile, and the feces becoming more and more dry and hard -Once defecation occurs, the wound that has been opened is deepened and the pain is further aggravated. The other is that some patients with anal fissures may think to themselves, “Oops! Constipation”, so they use laxatives immediately, which makes the stool softer or watery, resulting in several bowel movements a day, and constant fecal contamination and irritation of the wound, resulting in more frequent pain and inflammation. Dysentery and constipation are two abnormal bowel movements that can lead to fissures that do not heal over time and should be avoided and treated promptly. In addition, there are patients who take laxatives for a long time and in excessive amounts, so that the anus is not effectively dilated, resulting in anal stenosis or laxative-dependent constipation and colorectal melanosis, which may lead to the risk of cancer.
