What causes anal itching?

Anal itching can be caused by various factors, including but not limited to: 1. Anal eczema: Contact with irritants or allergens such as soap, detergent, or certain foods may cause skin inflammation and itching. 2. Fungal infection: Such as candidiasis, especially in moist environments, which can promote fungal growth and cause itching. 3. Parasitic infection: Such as intestinal roundworms or pinworms; their excretions or movement may irritate the skin around the anus. 4. Hemorrhoids: Itching may occur when internal hemorrhoids prolapse or external hemorrhoids become inflamed. 5. Skin diseases: Conditions such as dermatitis, urticaria, or psoriasis may also affect the anal area. 6. Personal hygiene: Poor cleaning habits or excessive cleaning may lead to dry and itchy skin. 7. Excessive secretion from perianal sweat glands: Increased local humidity may promote bacterial or fungal proliferation. To manage anal itching, it is recommended to keep the area clean and dry, use mild cleansing products, and wear breathable cotton underwear. If symptoms persist or worsen, timely medical consultation is advised; a doctor may perform examinations to determine the exact cause and provide appropriate treatment such as antifungal creams, antiallergic medications, or prescription drugs. Additionally, improving dietary habits, avoiding spicy foods, and consuming more fiber-rich foods can help prevent constipation and reduce irritation causing anal itching.
