 What is pruritus ani?
Pruritus ani is an intense chronic itching in the anal region. Usually, it begins gradually and becomes a self-perpetuating itch-scratch cycle.(14)
What are the causes of pruritus ani?
Pruritus ani is a common symptom that can be associated with a wide range of conditions:
- Diabetes, liver disease, thyroid disease
- Depression, anxiety disorders
- Fungal, bacterial and viral infections
- Allergic reactions eg, contact dermatitis caused by local anesthetics, such as "-caine" preparations
- Antibiotic treatment
- Chronic constipation, diarrhea, anal incontinence
- Local anal disorders: anal fissures (pruritus ani accompanies anal fissures in 50% of cases),(15,16) hemorrhoids and cryptitis. Only hemorrhoidal tags that are inflamed or associated with poor hygiene produce pruritus.(1)
- Ingestion of certain foods, especially spices, coffee, beer, cola and medications
- The perianal area can be highly sensitive to perfumes, soaps, clothes, fabrics, excessive sweating and superficial injury
- Hygiene, either poor with residual irritating feces or over meticulous with excessive use of soap and rubbing also may be associated with pruritus
If you are experiencing an intense chronic itching in the anal region, we recommend to consult your health care professional.
