What is pruritus ani?

Pruritus ani is an irritation of the skin surrounding the anus. It can result in severe itching and/or burning peri-anal pain. It is a common condition.

What causes this to happen?

Ironically, the two most likely causes are either over-cleaning, or not cleaning enough.

• Over-cleaning can remove natural oils that protect the skin.
• Increased moisture due to difficulty cleaning or increased mucous irritates the skin. This can cause itching, bleeding, and pain. An over-growth of 'yeast' makes it worse.
• Rarer causes can include: psoriasis, allergy to laundry detergents, eczema, dermatitis, or tumors of the skin.
• Foods that can sometimes affect itching: Caffeine, beer, chocolate, nuts and popcorn.
