Anal itching, also known as pruritus ani, can be a distressing condition that may arise from various causes, including excessive cleaning, skin irritation, infections, or underlying medical conditions. As a university student experiencing anxiety and obsessive cleanliness, it's understandable that you might be dealing with this issue, especially during stressful times like exams. Let's address your questions one by one.

1. Sitz Bath for Anal Itching: When it comes to anal itching caused by excessive cleaning, a sitz bath can be beneficial. A sitz bath involves sitting in warm water that covers the hips and buttocks, which can help soothe irritation and promote healing. However, it's crucial to balance this with proper hygiene. Over-cleaning can strip the skin of its natural oils, leading to dryness and irritation. Therefore, while a sitz bath can provide relief, you should also avoid using harsh soaps or excessive scrubbing in the anal area. Gentle cleansing with warm water and mild soap is usually sufficient. If the itching persists, consider consulting a healthcare professional for further evaluation.

2. Steroid Cream and Skin Weakness: Prolonged use of topical steroids, such as the one you mentioned ("樂癒痔"), can indeed lead to skin thinning or atrophy, especially in sensitive areas like the anal region. This could make the skin more susceptible to irritation and itching. If you've been using the cream for over a month, it's possible that this contributed to the fragility of the skin. It's advisable to use such medications under the guidance of a healthcare provider and to limit their use to the shortest duration necessary to manage symptoms.

3. Frequent Bowel Movements and Itching: Having bowel movements two to three times a day is generally considered normal, provided that the stools are well-formed and you are not experiencing diarrhea. However, frequent wiping after bowel movements can lead to irritation, especially if the skin is already sensitive. To improve this situation, consider using gentle, unscented wipes or a bidet after bowel movements to minimize irritation. Additionally, applying a barrier cream, such as zinc oxide or petroleum jelly, can help protect the skin from irritation.

4. Post-Meal Urge to Defecate: The sensation of needing to defecate shortly after eating, even when there is no stool present, can be attributed to the gastrocolic reflex. This reflex is a normal physiological response where the stomach signals the colon to make room for incoming food. However, if this sensation is accompanied by discomfort or if it becomes bothersome, it may be worth discussing with a healthcare provider to rule out any gastrointestinal issues.

In summary, managing anal itching involves a combination of proper hygiene, avoiding excessive cleaning, and using soothing treatments as needed. If symptoms persist or worsen, seeking advice from a healthcare professional is essential to rule out any underlying conditions and to receive appropriate treatment. Remember, maintaining a balance between cleanliness and skin health is key to preventing irritation in sensitive areas.
