A thread-like structure protruding from the anus during defecation may be caused by parasitic infections—such as roundworms—or undigested food. In patients with hemorrhoids, prolapse of internal hemorrhoidal tissue cannot be ruled out. If the patient experiences anal discomfort, prompt medical evaluation is strongly recommended. During treatment, maintaining local hygiene is essential; sitz baths with potassium permanganate solution may be used for cleansing.
