The appearance of meatballs after defecation is mainly considered to be internal hemorrhoids prolapse and rectal prolapse in anorectal diseases. Internal hemorrhoids mainly occur in the formation of varicose veins masses above the dentate line and the triggering causes include poor diet, poor defecation habits and congenital anal canal stenosis. After the development of internal hemorrhoids to stage II, the nucleus will prolapse out of the anus after defecation and form a ball of flesh at the anus, but it will often return on its own, while in stage III it will need to be returned manually, and in stage IV the enlarged nucleus will become embedded and is often accompanied by blood in the stool and a feeling of swelling. Rectal prolapse is caused by congenital poor intestinal development in infants and children, damaged rectal nerves in adults or weakness of the anal raphe and pelvic floor fascia, the rectal mucosa will prolapse outside the anus during defecation, the early stage of the mass is small and can basically be retracted by itself, the later stage requires manual retraction or cannot be retracted due to the large mass, and often forms a meatball at the anal opening. It is recommended to check the situation and take timely treatment measures.
