Anal Itching and Skin Irritation

Buttock Rectum | Dermatology | Anal Itching and Skin Irritation (Symptom)


The anal itching is the irritation of the skin at the exit of the rectum, known as the anus, accompanied by the desire to scratch. Although itching may be a reaction to chemicals in the feces, it often means that there is an inflammation of the area anal. If it is getting intense, anal itching can cause intolerable discomfort such as burning and pain.


Anal itching can be caused by irritating chemicals present in foods that are eaten such as spices, hot sauces and peppers. It can also be caused by irritation and continuous moisture in the anus, caused by frequent watery stools, diarrhea, or leakage of small amounts of stool. It can also be caused by the irritation of frequent liquid stools, diarrhea, or leakage of small amounts of stool (incontinence). Diseases that increase the possibility of yeast infections, such as diabetes mellitus or HIV infection, as well as treatment with antibiotics can lead to a yeast infection and irritation of the anus. Psoriasis also can irritate the anus. Abnormal passageways (fistulas) from the small intestine or colon to the skin surrounding the anus can form as a result of disease (such as Crohn's disease), and these fistulas bring irritating fluids to the anal area. Other problems that can cause anal itching include pinworms, hemorrhoids, tears of the anal skin (fissures), and skin tags (abnormal local growth of anal skin).

Diagnosis and Treatment

There are several measures you can take to relieve anal itching. It is important to keep the anal area clean by washing and drying carefully after a bowel movement. Avoid using soaps that irritate the skin, and use loose underclothes made of natural fibers. For pruritus ani of unknown cause treatment typically begins with measures to reduce irritation and trauma to the perianal area. Stool softeners can help prevent constipation. If this is not effective, topical steroids, capsaicin, or injected methylene blue may be prescribed by the doctor. ...
