Anal Itching (cont.)
Anal Itching Causes
When a cause can be found, the itching is usually due to irritation of the skin around the anus.
Some of the most common irritants include the following:
- Perfumes, chemicals, or dye on toilet paper can cause an allergic reaction.
- Moisture from sweat or diarrhea may cause itching. If the anal skin stays wet, the skin begins to break down.
- Some foods irritate the anus when they are expelled during a bowel movement. The most common culprits are caffeine, chocolate, beer, nuts, dairy products, and spicy food.
- Infections such as pinworms, yeast, and genital warts can cause itching.
- Hemorrhoids, which cause painful swelling of blood vessels in the anal area, can cause itching.
- Cancer, in rare instances, may be a cause of anal itching.
