Anal pruritus is a symptom of anorectal diseases, not an independent disease. Common reasons are as follows:

First, perianal diseases. Such as internal hemorrhoid, external hemorrhoid, mixed hemorrhoid, anal fissure, anal fistula, rectal mucosal prolapse, anal papillary fibroma, etc. Such diseases may secrete a lot of mucus, which contains a lot of bacteria, which will repeatedly stimulate the skin around the anus and cause anal pruritus and perianal eczema for a long time.

Second, intestinal parasite infection can also cause anal pruritus, which is more common in children.

Three, long-term eating spicy food, such as pepper, seafood, beef and mutton, will cause anal edema, congestion, and anal pruritus.
