Anal FissureAn anal fissure is a cut or tear occuring in the anus (the opening through which stool passes out of the body) that extends upwards into the anal canal. Common in infants ages 6 to 24 months, anal fissures are less likely to develop in older children. They are very common in people of all ages, but are most common in teenagers and young adults. The symptoms and signs include pain when passing a bowel motion and bright red blood from the anus. Fissures are a common condition of the anus and anal canal and are responsible for 6-15% of the visits to a colonic and rectal (colorectal) surgeon. Anal fissures may cause pain and bleeding. More than 90 percent heal on their own, and you can use topical creams or suppositories to provide relief as they heal. The fissure may not heal and may become chronic . This is because the blood supply may be reduced to the skin of your anus due to the muscles tightening in response to the pain , so preventing healing. At a line just inside the anus--referred to as the anal verge or intersphincteric groove the skin (dermis) of the inner buttocks changes to anoderm. The hairless, gland-less, extremely sensitive anoderm continues for the entire length of the anal canal until it meets the demarcating line for the rectum, called the dentate line. (The rectum is the distal 15 cm of the colon that lies just above the anus and rectum and just below the sigmoid colon.) Most people have experienced a tear or fissure at the corner of the mouth that can occur in cold weather or when yawning. A hard, dry bowel movement results in a break in the tissue. It can cause sharp pain, especially when opening the bowels. Anal fissures do not lead to more serious conditions such as colon cancer. Occasionally a fissure takes more than 6 weeks to heal (chronic anal fissure), in which case it usually requires medication to heal. Anal fissures affect people of all ages, particularly young and otherwise healthy people. They are equally common in men and women. Injury to the anal area during childbirth and abuse of laxatives may be other causes. This is because the anus and anal canal are ringed with muscles to control the passage of stool and to keep the anus tightly closed at other times. When those muscles expand, it stretches the fissure open. There may also be bleeding or itching with an anal fissure. Causes of Anal FissureThe common Causes of Anal Fissure :
