 Why Am I So Itchy Back There?

You may feel hesitant to discuss anal itching with a health care provider, but this issue is nothing to feel embarrassed about.

Anal itching is rarely a sign of something serious but can be intense and disruptive to your daily life. If you’re struggling with bothersome itching, Dr. Perryman can evaluate your symptoms and get to the root cause.

Anal itching

There’s no need to fret over an occasional itchy anus, but persistent anal itching isn’t normal, and it’s important to find the cause. Known medically as pruritis ani, anal itching is an irritating sensation around the anus. In most cases this is not due to a disease of the anus or rectum or a problem with the digestive tract.

Common causes of anal itching

Diagnosing anal itching involves a thorough review your symptoms, medical history, and a physical examination. The following are some of the most common causes of anal itching.

Diet

Certain foods and beverages can irritate the colon and rectum, triggering anal itching and discomfort. Some of the most common culprits are:

Skin conditions

Infections

Sexually transmitted infections (STIs), parasitic pinworm infections, and yeast infections are just a few types of infections that can cause anal itching.

Colorectal and anal disorders

Once diagnosed, Dr. Perryman can advise you on a treatment plan. It’s best to avoid scratching or rubbing the anal area while you seek evaluation of your symptoms.
