What is it?
Pruritus ani (say "proo-RYE-tus AY-nye") means an itch in or around the anus. It can come and go or be constant, and is often worse at night or after a bowel movement. Scratching irritates the skin and makes the itch worse, which creates an itch-scratch cycle. It is uncomfortable and sometimes embarrassing, but it is rarely a sign of something dangerous.
How common is it?
It is a common complaint and affects people of all ages, more often adults and more often men. Many people never mention it to a doctor because of embarrassment, but it can usually be helped.
Why does it happen?
In many people no single cause is found (primary pruritus ani), and the usual triggers are moisture, sweat, small amounts of stool leakage, and over-washing or wiping with soap, wipes or perfumed products that irritate the skin. Other causes include haemorrhoids, small anal tears (fissures), fistulas, skin conditions such as eczema or psoriasis, fungal or yeast infections, pinworms (more in children), diabetes, loose stools, and certain foods or drinks such as coffee, tea, chocolate, spicy foods and citrus in some people. Rarely, it is linked to a skin or anal cancer.
Symptoms
- Itching or burning around or just inside the anus
- Itch that is worse at night or after bowel movements
- Red, sore or thickened, pale skin around the anus from scratching
- Small cracks or raw areas in the skin
- Dampness or a feeling of not being clean after wiping
- Poor sleep because of the itch
Red flags — seek urgent medical care
Bleeding from the anus or blood on the paper that is new or keeps happening
Blood needs to be checked by a doctor to rule out a bowel or anal condition. Do not assume it is only piles. Book an appointment soon; go to the emergency department if bleeding is heavy.
A lump, ulcer or sore that does not heal, or skin that looks white, red or crusted in a patch
Needs examination, and sometimes a small skin sample, to exclude a skin condition or cancer. See a doctor soon.
Itching that does not improve after a few weeks of gentle care
May need a cause looked for, such as an infection, a skin condition or a bowel problem.
Unexplained weight loss, a change in bowel habit, or constant severe pain
May point to a bowel condition that needs assessment promptly.
Swelling, spreading redness, pus or fever
Could be an infection or abscess. See a doctor the same day.
How is it diagnosed?
The doctor asks about your hygiene habits, products you use, diet, skin conditions and bowel habit, then examines the skin and the anal area, often with a gentle finger examination and a short look inside with a small instrument. Tests are chosen by the findings and may include a swab for infection, a tape test for pinworms, blood sugar testing, a skin sample, or a bowel examination such as colonoscopy if there are other symptoms. Often no tests are needed.
Outlook — what to expect
Most people improve when the skin is protected and the triggers are removed, although the itch can take weeks to settle and may come back. When a specific cause is found and treated, the itch usually clears.
Treatment
Habits & Lifestyle
Gentle skin care is the most important treatment. The aim is to keep the area clean, dry and not irritated.
- Clean with plain lukewarm water after bowel movements; avoid soap, perfumed wipes and strong cleansers
- Pat dry gently or use a hairdryer on a cool setting; do not rub
- Do not scratch; keep nails short and consider cotton gloves at night
- Wear loose, breathable cotton underwear and change it when damp
- A small piece of dry cotton wool or gauze can absorb moisture; avoid talc and creams unless advised
- Wash your hands and treat the whole household if pinworms are found, as your doctor advises
Diet
Food does not cause the problem in everyone, but some people notice that certain items make the itch worse.
- Try cutting back on coffee, tea, cola, chocolate, spicy food and citrus for a few weeks to see if it helps
- Eat enough fibre and drink fluids to produce formed, easy-to-pass stools and avoid leakage
- Reintroduce foods one at a time so you can tell which ones matter
Medications
Treatment depends on the cause. Do not use steroid creams for more than the short time your doctor advises, because they can thin the skin.
- A simple barrier cream or ointment to protect the skin, if your doctor or pharmacist suggests one
- A short course of a mild steroid cream for inflamed skin, only as prescribed
- Antifungal or antibiotic treatment if a fungal or bacterial infection is found
- Anti-worm treatment if pinworms are the cause
- Treatment of the underlying problem, such as haemorrhoids, fissures, diarrhoea or diabetes
Procedures & Surgery
Procedures are rarely needed and only apply when another anal condition is the cause.
- Treatment of haemorrhoids, a fissure or a fistula if one is found
- A small skin biopsy if the skin looks unusual or does not respond to treatment
- A bowel examination such as colonoscopy if there are other bowel symptoms
Living with the condition
- Many people need to keep up the skin-care habits long term to prevent it coming back
- Do not feel embarrassed; doctors see this often and it usually improves
In the Saudi context
Washing with water after using the toilet is common and good for cleanliness. Use plain lukewarm water, avoid scented soaps, and dry the area gently afterwards, as staying damp can keep the itch going.
