Pruritus Ani

What Causes Anal Irritation?

Pruritus Ani translates directly to itchy anus. The most common cause of Pruritus Ani is over cleaning the perianal skin. Sometimes the original cause has passed, but scratching creates an “itch-scratch cycle” that worsens irritation.

Anal irritation or itching can also be caused by:

• Diarrhea or frequent liquid stools
• Residual stool deposits or fecal incontinence
• Anal perspiration
• Fungal or yeast infections (such as Candida)
• Hemorrhoids, skin tags, or fissures
• Allergic reactions to soaps, wipes, or hygiene products
• Skin conditions like psoriasis and lichen sclerosus.

Symptoms
Seek medical attention if itching persists for more than a few days or is accompanied by:

• Pus or blood around the anus
• Bulging or protruding hemorrhoids
• Persistent soiling or thickened/dull skin around the anus

Diagnosis
One of our colorectal specialists will examine the anal area and discuss your medical history, once you have been referred to us.

Tests may include:

• Skin scraping to check for fungal infection
• Sticky tape test for pinworms
• Anoscopy to examine the anal canal

Treatment
Treatment focuses on reducing irritation and breaking the itch-scratch cycle:

• Keep the area clean and dry after bowel movements and at night, avoiding soap and pre-moistened wipes
• Apply topical creams if recommended (steroids, antifungal, or antibiotic)
• Use medications for parasitic infections like pinworms
• Treat underlying conditions such as hemorrhoids, psoriasis, or infections

With proper care, most cases of anal irritation can be successfully managed and discomfort greatly reduced.
