The perineum of our body is a densely populated area of painful nerves, so many of the ailments that occur near this area can cause us pain, and the appearance of anal fissures makes patients feel as if they are being pricked by pins and needles, and as if they are being burned by fire, and the pain is so unbearable that patients feel as if they are being split open. Modern medicine believes that anal fissure is a chronic ischemic ulcer, which is directly caused by local injury caused by dry stool and excessive force during defecation, and secondary traumatic infection forms chronic anal fissure, which is difficult to heal over time. Patients often suffer from periodic anal pain during defecation, blood on toilet paper or blood on the surface of stool, vicious cycle of constipation, anal dampness and itching, and various anal local discomfort. Anal fissures are divided into acute anal fissures and old anal fissures, and most of the fissures that we usually say are ineffective in conservative treatment and require surgery are chronic old anal fissures that are difficult to heal and have produced various complications. Once an anal fissure occurs, almost all of them will turn into chronic fissures if they are not treated in time, which will not only cause more painful symptoms and affect the quality of life, but also produce a series of complications that make surgery complicated and care much more difficult, and the chance of postoperative complications is great, prolonging the recovery time after surgery and greatly increasing the patient’s pain. But anal fissures are also prone to favor some people with bad habits, such as those who have a diet of greasy, spicy, pickled, heavy food; those who love to drink alcohol or even long-term alcoholism; those who drink less water every day and do not consume enough water; those who do not like to eat vegetables and fruits and consume less dietary fiber; those who stay up late for a long time, work under a lot of stress, mental tension and endocrine disorders. If you don’t want the pain of anal fissure to affect your life, you should start by correcting some bad habits in your life. However, if you are unfortunate enough to have an anal fissure, you need to go to a regular anal hospital for treatment as soon as possible, so as not to let the fissure tear up our lives.
