There are three main types of hemorrhoids: internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. The main clinical manifestations of mild internal hemorrhoids are bleeding and prolapse after stool. Intermittent fresh blood after stool is a common symptom of internal hemorrhoids. When no thrombosis, impaction or infection occurs, internal hemorrhoids are usually painless and some patients have difficulty defecating. The clinical work will be subdivided into two degrees of mild hemorrhoids, once mainly manifested as blood in the stool, dripping or jet bleeding, which can stop on its own after the stool, without any obvious prolapse of the hemorrhoid nucleus. In the second degree, there is blood in the stool, and the hemorrhoid prolapses during defecation or with straining, and can be self-circumscribed after the stool. Mild external hemorrhoids are mainly characterized by anal discomfort, moist and unclean, sometimes with itching, and often small skin drops around the anus. Mild external hemorrhoids are not prone to thrombosis and occasionally have pain, but it is not severe and can often resolve on its own. When hemorrhoids develop into mixed hemorrhoids, the condition is usually more severe, with symptoms of both internal and external hemorrhoids.
