What are the symptoms of hemorrhoids? Hemorrhoids are not the commonly recognized “sores” caused by bacterial infections, but rather enlarged, varicose veins in the mucosa of the lower rectum, the anal canal and the skin under the anal verge. Antibiotics are generally not needed for hemorrhoids unless they are combined with an infection in the anus. The hemorrhoids can be divided into internal, external and mixed hemorrhoids, each with different symptoms, using the dentate line as a boundary. The main symptoms of internal hemorrhoids are blood in the stool and prolapse of the mass. The initial stage of internal hemorrhoids is characterized by blood. The nucleus of the hemorrhoid is small and soft, the surface of the hemorrhoid is bright red, and the nucleus does not come out of the anus when defecating. As time goes by, the nucleus becomes larger and larger, and at the later stage, it can even prolapse when walking, coughing, sneezing, or standing, and cannot be retracted by itself, but must be pushed back by hand, or can only be retracted after lying down or applying heat. The blood in the stool is either blood on hand paper or dripping blood, and does not mix with feces. As the internal hemorrhoids deepen, the pain will become more intense. The main symptoms of external hemorrhoids are anal swelling, pain, and foreign body sensation. According to its development process, it can be divided into connective tissue external hemorrhoids, varicose veins external hemorrhoids and thrombotic external hemorrhoids. The main symptoms of mixed hemorrhoids are: blood in the stool, prolapse of swelling and painful itching in the anus. (1) Blood in the stool: the main symptom in the early stage, jet or drip bleeding, bright red blood, can occur before or after the stool. (2) Pain: Simple internal hemorrhoids are painless, a few have a feeling of swelling, when internal hemorrhoids or mixed hemorrhoids prolapse and become embedded, edema, infection, necrosis, there are varying degrees of pain. (3) Mass prolapse: The main symptom of middle and late stage internal hemorrhoids, most of them have blood in stool first and then prolapse, because the hemorrhoid body increases in late stage, it gradually separates from the muscle layer and is pushed out of the anus when defecating. In mild cases, the hemorrhoid only prolapses during stool and can return on its own after stool; in severe cases, it needs to be pushed back by hand, and in more serious cases, it can be pushed out of the anus with slight abdominal pressure.
