Ascaris lumbricoides (roundworm)
Hello, doctor: I often experience itching around the anal area while sleeping at night.
Could this be due to having roundworms in my abdomen? Is it contagious to my family? Or could there be other reasons? Which specialist should I see? Thank you!

Anal itching may be caused by a pinworm infection or sensitivity of the skin around the anus.
In the case of a pinworm infection, it can be transmitted to family members, so a stool test should be conducted to check for the presence of eggs.
Please schedule an appointment with a colorectal specialist for an examination to confirm the diagnosis.

More Info
Anal itching, or pruritus ani, can be a bothersome condition that affects many individuals. Your concern about whether this itching is due to pinworms or another cause is valid, as pinworms (Enterobius vermicularis) are a common cause of anal itching, particularly in children. However, there are several other potential causes of anal itching that you should consider.
Pinworms
Pinworms are small, white, thread-like worms that can infect the intestines, particularly in children. The female pinworm lays eggs around the anus, which can cause intense itching, especially at night. If you suspect pinworms, it is essential to look for other symptoms such as:
- Visible worms in the stool or around the anal area.
- Sleep disturbances due to itching.
- Irritability or restlessness in children.
Pinworms are highly contagious and can easily spread among family members, especially in households with children. They can be transmitted through direct contact or by touching contaminated surfaces, such as bedding or clothing. If pinworms are confirmed, treatment typically involves over-the-counter medications like mebendazole or pyrantel pamoate, and it is advisable for all household members to be treated simultaneously to prevent reinfection.
Other Causes of Anal Itching
While pinworms are a common cause, there are numerous other potential causes of anal itching, including:
1. Hygiene Issues: Insufficient cleaning after bowel movements can lead to irritation and itching. Conversely, excessive cleaning or using harsh soaps can also irritate the sensitive skin around the anus.
2. Skin Conditions: Conditions such as eczema, psoriasis, or contact dermatitis can cause itching in the anal area. These conditions may require topical treatments or lifestyle adjustments.
3. Infections: Fungal infections, such as yeast infections, or bacterial infections can lead to anal itching. These infections may present with additional symptoms like redness, swelling, or discharge.
4. Hemorrhoids: Swollen blood vessels in the rectal area can cause discomfort and itching. Hemorrhoids may also cause bleeding during bowel movements.
5. Dietary Factors: Certain foods, such as spicy foods, caffeine, and alcohol, can irritate the anal area and lead to itching.
6. Sexually Transmitted Infections (STIs): In some cases, STIs can cause anal itching and discomfort, particularly if there are lesions or other symptoms present.
When to See a Doctor
If your anal itching persists despite good hygiene practices or if you notice other concerning symptoms such as bleeding, significant pain, or changes in bowel habits, it is advisable to consult a healthcare provider. You may want to see a gastroenterologist or a dermatologist, as they can help diagnose the underlying cause of your symptoms and recommend appropriate treatment.
Conclusion
In summary, while pinworms are a possible cause of your anal itching, it is essential to consider other potential causes as well. Maintaining good hygiene, monitoring your symptoms, and consulting a healthcare professional if the itching persists or worsens will help you find relief and address any underlying issues. Remember, it is always better to seek medical advice for a proper diagnosis and treatment plan tailored to your specific situation.
