3. Allergic reaction: Eating irritating foods, such as peppers, mustard, spices, alcohol or specific protein foods, and taking certain medications can cause anal itching due to allergies.

4. Endocrine diseases: For example, the sugar content in the skin of diabetic patients increases, which stimulates the nerve endings and causes itching; the itching of skin cancer in hyperthyroidism may be related to excessive sweating, increased basal metabolic rate, and emotional tension.

5. Parasitic diseases: such as exuviae, ascariasis, vaginal trichomoniasis, pubic lice, scabies, etc., can all cause anal itching.
