What causes pimples to grow around the anal area?

Acne-like bumps around the anus may be caused by various factors, mainly including folliculitis, condyloma acuminata, perianal abscess, and anal polyps. 1. Folliculitis is caused by poor hygiene around the anus, leading to bacterial infection of the hair follicles. It results in acne-like symptoms accompanied by redness, swelling, and itching. 2. Condyloma acuminata is caused by infection with the human papillomavirus (HPV). It presents as tiny, flesh-colored bumps around the anus, often multiple or clustered, growing rapidly and possibly accompanied by itching or bleeding. 3. Perianal abscess is usually caused by long-term constipation, diarrhea, or other factors. It presents as acne-like lesions on the anus, accompanied by significant redness, swelling, and pain. 4. Anal polyps, when large enough, may protrude from the anus, presenting as small, pimple-like growths, and may be accompanied by symptoms such as rectal bleeding and prolapse. All of the above conditions require timely medical attention and targeted treatment based on the specific cause. At the same time, maintaining proper hygiene around the anus and avoiding unprotected sexual activity are important measures for preventing such problems.
