Hemorrhoids do not block the stool. Hemorrhoids are divided into internal, external and mixed hemorrhoids according to the site of occurrence. Internal hemorrhoids are varicose veins that occur above the dentate line of the anus and are covered with mucous membrane, often with painless blood in the stool and prolapsed hemorrhoids as the main symptoms. External hemorrhoids are located below the dentate line and are masses formed by varicose veins, inflammation of the skin of the anal folds, hypertrophy, connective tissue hyperplasia or thrombotic stasis. External hemorrhoids are covered with skin and can be seen on the surface, cannot be sent into the anus, do not bleed easily, and have pain and foreign body sensation as the main symptoms. They are often clinically classified as connective tissue external hemorrhoids, varicose external hemorrhoids, inflammatory external hemorrhoids and thrombotic external hemorrhoids. Dry stools and constipation are predisposing factors for hemorrhoids, which can increase the pressure within the submucosal venous plexus at the end of the rectum, resulting in dilated and tortuous blood vessels that can easily induce hemorrhoids. When hemorrhoids flare up and become swollen and painful, constipation can aggravate the pain of the hemorrhoids, and the stool can be as sharp and painful as glass cutting through a wound during defecation. Many patients are afraid to defecate for fear of pain, resulting in dry stools that are more difficult to pass and aggravate the pain, mistaking hemorrhoids for blocked stools and needing to solve the constipation to pass stools instead of hemorrhoids blocking stools.
