It is also believed that hemorrhoids are the result of downward migration and hyperplasia of the anal cushion, which is the normal anatomical structure of the anal canal, namely the vascular cushion, which is the dentate line and a 1.5 cm ring of sponge-like tissue. Only when the anal cushion tissue is subluxated and combined with symptoms, it can be called hemorrhoid disease. Hemorrhoids are divided into internal, external and mixed hemorrhoids, with the dentate line as the boundary. Common symptoms of hemorrhoids: 1. Blood in the stool: internal hemorrhoids are painless, intermittent, fresh blood after the stool, dripping or squirting blood during the stool or blood on hand paper, aggravated by constipation, drinking alcohol or eating irritating food. 2.Prolapse: Internal hemorrhoids are painless and swollen, and gradually develop into prolapse, with pain, itching and mucous discharge when combined with thrombosis, impaction and infection. 3.Swelling: External hemorrhoids usually have no special symptoms, but when thrombosis and inflammation occur, there can be swelling and pain.
