The anal fissure cause is mostly due to hard stool passing through the anal cavity. In women the anal fissure cause is much different and more common, as the space between the vaginal and anal cavities is very thin. The anal fissure cause can usually be fixed over time if bowel movements arent held in and a good diet with fiber is maintained. The anal fissure cause can be found in a persons diet, hard stool will tear the thin lining in the anal cavity. The other anal fissure cause may also be anal intercourse. Any objects put into the anal canal may also be a cause of an anal fissure.

The anal canal is very delicate and fissures tend to be very painful and very hard to heal. Large stool causes the anal cavity to stretch; the stool usually becomes hard because of constipation and holding bowel movements in. In pregnant women anal fissures tend to be more common as they seem to hold stool in and have more constipation issues rather than men. Anal fissures occur closest to the spine area where the skin is the thinnest.

Fissures can also be caused by a doctors tool. Some doctors even though they take care when working in the anal region may inadvertently tear the anal lining. This is another cause which is not so common in people but can occur. Fissures may also cause skin tags to occur around the bottom of the anus. Fissures in the anus generally take a long time to heal as there is no normal glands in the area which are found every where else on the body. Anal fissures tend to rip open very easily which causes them to be very painful and makes going to the bathroom a nightmare for some.

Many anal fissures will cause bleeding; this is essence the definition of an anal fissure. Some will heal on their own at times but many people experience chronic anal fissures or one that lasts for long periods of time.
