What are the main causes of frequent anal itching?

The main causes of chronic anal itching include the following: 1. Improper diet: Long-term consumption of spicy and irritating foods, such as chili peppers and garlic, can irritate the skin around the anus and cause itching. 2. Allergic reactions: Certain substances, such as pollen, medications, or chemicals, may trigger allergic reactions in the anal area, leading to itching. 3. Parasitic infections: Parasites such as pinworms can lay eggs or move near the anus, causing itching. 4. Hemorrhoids and anal fissures: These conditions can increase anal secretions, which chronically irritate the perianal skin and lead to itching. 5. Skin disorders: Conditions such as anal eczema or fungal infections can also cause anal itching. Poor hygiene habits, medication use, and psychological factors may also contribute to anal itching. To prevent and treat anal itching, it is recommended to maintain a light diet, practice good personal hygiene, avoid contact with allergens, and seek timely medical diagnosis and treatment.
