why is my butthole itchy

An itchy butthole (anal itching or pruritus ani) can be caused by many factors. Common causes include poor hygiene (both washing too much or too little), irritation from soaps or scented wipes, skin conditions like eczema or psoriasis, infections including sexually transmitted infections or parasites like threadworms, hemorrhoids, anal fissures, and certain foods or medications that cause irritation. Scratching worsens the irritation, so gentle cleaning and avoiding irritants are important. In rare cases, systemic conditions such as diabetes, anemia, or even anal cancer may cause itching. It is usually a symptom of irritation or an underlying condition rather than a disease itself, and most cases can be managed with lifestyle changes or medical treatment when needed.
