Anal Itching Causes, Symptoms, Diagnosis and Treatment

Anal itchiness is a common condition. Severe itching in or around the anus can be quite uncomfortable and unsightly.

Anal itching is also referred to as pruritus, and it can have several reasons. They include infections, haemorrhoids, and persistent diarrhoea. Another factor is dermatitis, which is another term for skin irritation.

If taking care of yourself isn't relieving the symptoms, consult your doctor. Following therapy, the majority of patients experience complete relief.

Causes Of Anal Itching

In addition to food and beverages, the following things can also cause itching in the anal area:

  • Products made from dairy.
  • Carbonated drinks.
  • Caffeine-containing beverages, such as tea, coffee, and soda.
  • Foods such as raw garlic, tomatoes, citrus fruits, and chilli peppers that are acidic or hot.
  • Your clothing could also affect the skin in that location. Wearing tight garments can make itching worse by encasing your anus in heat and moisture (sweat).

Additional causes of anal irritation include:

Haemorrhoids

Haemorrhoids are swollen, enlarged veins that can be found both inside and outside of your rectum and anus. It can be difficult to pass excrement after using the loo if you have huge haemorrhoids that are not inside your anus. Internal haemorrhoids, or haemorrhoids that are located inside your rectum, can cause bleeding or a leaky anus (incontinence or faecal soiling) in addition to irritating your skin.

Yeast infections

A kind of fungal organism called candida is the source of yeast infections. Candida is a specific type of fungus, of which yeast is one. Yeast infections might be coming from your anus or vagina. Furthermore, they may cause localised skin discolouration, oedema, and tiny cuts or fissures.

Anal Fissures

Anal fissures are tears in the lining of your anus or anal canal, the opening through which waste exits your body. Trauma to the area is the main cause of anal fissures. Trauma symptoms include anal sex, anal stretching, persistent diarrhoea, constipation, and straining when peeing.

HPV and warts

The human papillomavirus (HPV), which is quite common, can infect both your genitalia and your rectum.

Genital warts are one type of sexually transmitted illness. The illness may cause little growths or bumps called warts to emerge in and around your genitalia and perianal area. There are other signs of vaginal warts, such as discomfort, burning, and mild bleeding.

Threadworms are small white or light grey worms, commonly called pinworms. Pinworms are parasites that depend on hosts—other living things—for growth, reproduction, and nourishment. Parasites cause harm to hosts.

Pinworms live in the rectum and intestines of infected people. When they lay their eggs there at night, your anus will begin to itch.

Diagnosis Of Anal Itching

By asking about your lifestyle, medical history, and symptoms, your doctor may be able to identify the cause of your itching. A medical examination might be required, which could involve a rectal examination. You may be tested for pinworms if you believe you may have an infection.

If the cause of your itching is unknown or if treatment doesn't seem to be helping, your doctor might advise you to consult a specialist in skin conditions. This type of medical professional is known as a dermatologist. The symptoms are usually manageable, even if the cause of the itching is often unknown.

Treatment Of Anal Itching

Maintaining good anal hygiene is typically the initial course of treatment for an itchy anus. Wipe your anus well, pat dry, and use non-medicated talcum powder after urinating.

The specific cause of your secondary pruritis ani will dictate the course of treatment for you.

Several potential therapies include:

Creams and ointments

Hydrocortisone, an anaesthetic and corticosteroid, is available over-the-counter (OTC) and can be applied to the affected area twice or three times a day.

Research suggests that in cases of chronic anal itching, topical capsaicin cream could be a good alternative to corticosteroids.

Antifungal and antibiotic medications

Your physician may suggest antibiotics or antifungal medications if they believe that an infection is the source of your itchy anus.

Methylene blue injection (tattooing the anus)

If your body doesn't respond to other treatments, your doctor may administer an injection of methylene blue to relieve your itchy anus. Your medical practitioner will inject methylene blue just under your skin in the perianal area. Pain and discomfort are reduced when methylene blue is injected because it deadens the nerve endings in certain areas.

Anal inflammation can be caused by a variety of things. The skin around your perianal area is fragile. Scented soaps, powders, lotions, creams, and ointments can trigger allergic reactions. Furthermore, cleaning the area with abrasive washcloths, toilet paper, or hot water may irritate your skin.

Be sure to thoroughly wipe your anus after urinating. The stool that remains in your anus's folds can itch in your perianal region. The kind and frequency of your bowel motions may also have an impact on anal irritation. Anal irritation is more likely to occur if you have constipation, or loose stool, three times or fewer per week.
