What causes frequent anal fissures? There are 5 reasons for this

Although anal fissure is not a serious disease, it often makes people feel restless, especially when defecating, which is extremely painful. So what exactly causes people to suffer from anal fissures so often? In fact, from a medical point of view, anal fissures are often caused by five elements. Let’s start with anatomical factors!

1. Anatomical factors: The superficial part of the external anal sphincter starts from the coccyx and extends forward to the back of the anus. The front and back of the anus are not as strong as the sides and are easily injured. Therefore, the back of the anus is under greater pressure from feces, and the blood circulation in the back of the anal canal is insufficient, the elasticity is poor, and there are more anal glands, all of which are factors that lead to anal fissures.

2. Trauma theory: Dry and hard feces or foreign objects can easily cause damage to the skin of the anal canal, which is the main factor causing anal fissure.

3. Infection theory: It is mainly anal crypt infection behind the anus. The inflammation spreads to the subcutaneous part of the anal canal, causing the subcutaneous abscess to rupture and form anal fissure.

4. Internal sphincter spasm theory: Due to damage to the anal canal or inflammatory stimulation, the anal sphincter is in a spasm state, which increases the tension of the anal canal and makes it easy to be damaged into anal fissure.

5. Anal stenosis theory: The anal canal skin develops slowly, resulting in a narrow anal canal that is easily damaged and forms anal fissures.

Clinical data show that the incidence of anal fissures is second only to hemorrhoids. This shows that anal fissures are very common. It is recommended to understand the common causes mentioned above. In addition, there are also high-risk groups for anal fissures, such as postpartum women, so you should be vigilant.
