Pruritus ani can often be caused by which factor?

Pruritus ani, or anal itching, can indeed be caused by a variety of factors, which is why the answer is all-encompassing. Each of the factors listed contributes to this condition in different ways.

Infection can lead to pruritus ani as certain infections, such as pinworms or yeast infections, often result in irritation and itching in the anal area.

Dietary choices are another significant factor; consuming certain foods, such as spicy foods or caffeinated beverages, can irritate the digestive tract and exacerbate itching.

Skin irritation is also a common cause, which can arise from poor hygiene, excessive moisture, or use of irritating soaps and wipes that can lead to inflammation and discomfort.

Since all these factors can contribute to the symptom of pruritus ani, selecting the option that includes all of them captures the comprehensive nature of potential causes.
