Rectal polyps may cause a sensation of anal heaviness or prolapse, primarily influenced by factors such as the location, size, and number of the polyps. Below are possible causes and explanations: 1. Polyp location: Rectal polyps are located within the rectum. When polyps are large or numerous, they may compress surrounding rectal tissues and organs. This pressure can be perceived in the anal area, resulting in a sensation of downward dragging or heaviness. 2. Polyp size: Larger rectal polyps, due to their weight or traction from passing stool, may prolapse (protrude) from the rectum, further intensifying the feeling of anal heaviness or descent. 3. Associated symptoms: Rectal polyps may also be accompanied by other intestinal irritative symptoms such as abdominal pain, diarrhea, or constipation. These symptoms often interact with the sensation of anal heaviness, potentially creating a vicious cycle. The sensation of anal heaviness caused by rectal polyps is thus the result of multiple interacting factors. If such symptoms occur, it is recommended to seek timely medical evaluation to determine the underlying cause and receive appropriate treatment.
