Hemorrhoids are a good and frequent cause of anorectal diseases. They are divided into internal, external, and mixed hemorrhoids, and their onset is related to occupation, gender, age, and diet. Three major clinical manifestations of hemorrhoids: Blood in the stool: Blood in the stool is an early symptom that is bright red and does not mix with feces, which is important to distinguish from cancer. Prolapse: When the nucleus of the hemorrhoid is large, it is expelled from the anus under the pressure of defecation. Pain: The nucleus often prolapses and is prone to edema, thrombosis with inflammation, and painful impaction. There are also other manifestations, such as anal prolapse and anal dampness. So, how do you know you have hemorrhoids and not another anal disease? It is best to go to the anorectal department of a hospital and ask a professional physician to conduct an examination to clarify the diagnosis. If you can’t go to the hospital at the moment, you can make a simple determination on your own. If you have blood in your stool with fresh blood and no pain, it is usually an internal hemorrhoid. A soft swelling comes out with the stool. This is often an internal hemorrhoid. If there is a sagging skin or flesh at the anal opening, without pain or itching, it is usually an external hemorrhoid. If there is no pain and softness at the anal opening and the swelling is suddenly painful, it is an inflamed external hemorrhoid. If there is a swelling at the anal opening that is painful or very painful, it is often an embedded internal hemorrhoid. In addition, there are other discomforts, may be other anorectal disease or hemorrhoids with other anorectal disease. We find that blood in the stool is often the only symptom in clinical stage one or two internal hemorrhoids. The elderly tend to see hemorrhoid prolapse and relatively little blood in the stool, so the elderly must be examined for blood in the stool to avoid missing diseases such as tumors or ulcerative colitis.
