Internal hemorrhoids refer to the soft venous masses formed by the dilation and varicosity of the hemorrhoidal venous plexus located beneath the mucosa at the end of the rectum, above the dentate line of the anus. Once these masses have formed, they contain blood vessels which can rupture, leading to bleeding during bowel movements, evident as blood mixed with stool. Once these pathological masses have formed, it is very difficult to completely heal them with medication alone; surgical removal of these venous masses is required to prevent recurrent bleeding. Therefore, if conservative treatment is applied, it only slightly alleviates symptoms. If any triggering factors are present, bleeding may recur.
