Q: Are there many other types of hemorrhoids? A: Yes, hemorrhoids are actually anorectal hemorrhoids and fistulas, which are common and common diseases unique to humans. Hemorrhoids are divided into internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. The nucleus of the hemorrhoid is located inside the mucous membrane of the anus called “internal hemorrhoid”, located near the inner side of the anal opening called “external hemorrhoid”. If you have both, it is called “mixed hemorrhoids”. The symptoms of hemorrhoids are pain and blood in the stool, and in severe cases, the hemorrhoid will protrude out of the anus (prolapse) and retract only after defecation. Internal hemorrhoids are the most common, accounting for 52.19% of all anorectal diseases.
