The main symptoms of internal hemorrhoids are bleeding and protrusion, where the hemorrhoidal tissue prolapses outside the anus. There are several types of bleeding: the first is dripping blood during defecation, where blood drops steadily. Another type is spraying blood, similar to the way a syringe ejects fluid; these are all categorized under rectal bleeding. For internal hemorrhoids, the presence of either bleeding or prolapse outside the anus indicates a need for surgical treatment. This means that if internal hemorrhoids cause spraying blood, surgical treatment is required (i.e., removing the hemorrhoidal tissue), which can improve the bleeding and spraying issues.
