Dr. Li Jingxiang

Itching around the anus at night is common and may be caused by the following reasons:

1. It could be a condition caused by parasitic infections from exposure to external environments.

2. It might also result from abnormalities in the veins around the anal area due to external hemorrhoids.

3. It could be symptoms caused by an anal fissure.

4. Dermatitis, eczema, and allergic reactions can also lead to anal itching.

In addition, unhygienic sexual practices, excessive use of medications, and similar factors may also cause anal itching.

When experiencing frequent anal itching, it's advisable to avoid greasy and spicy foods.
