Pruritus Ani
Pruritus ani is a dermatological condition that makes the anal area itch, often worsening at night or after bowel movements.
It is classified into two types:
- Primary pruritus ani: This type occurs without an obvious cause and is the most common form of anal itching.
- Secondary pruritus ani: This type may be caused by infections, systemic diseases (e.g., diabetes, thyroid disorders), blood disorders, and skin conditions (e.g., contact dermatitis, psoriasis).

Treatment
Treatment focuses on keeping the anus and surrounding area clean and dry – clean thoroughly after bowel movements and keep the area dry. You can apply non-medicated, additive-free talcum powder if needed. Further treatment targets the specific underlying causes.
Some helpful things you can do:
Avoid products that irritate your skin, such as certain toilet papers, soaps, wipes, perfumes, deodorants, and laundry powders containing dyes or scents. If you notice a link between symptoms and a recent product change, switch back. Some wipes and creams may provide temporary relief but can trigger allergic reactions with prolonged use, so avoid long-term use unless a doctor advises. Also, wear loose clothing and minimise moisture buildup to prevent worsening itching.
Avoid certain foods and drinks:
Dairy products, carbonated drinks, coffee, tea, and spicy foods can trigger anal itching. Check whether your symptoms link to what you have been eating.
When should I seek medical attention?
If you have symptoms such as stool bleeding, a lump, pain, or chronic diarrhoea, seek medical attention right away. If simple measures fail to alleviate symptoms, it is critical to investigate other possible causes. If the skin becomes extremely red and excoriated, it may indicate an underlying allergy or infection, and it is recommended that you see a doctor right away.
