Internal hemorrhoids and external hemorrhoids are both typical symptoms of hemorrhoids and can be distinguished by their clinical manifestations. The main clinical manifestations of internal hemorrhoids are bleeding and so on, while the main clinical manifestations of external hemorrhoids are anal discomfort and so on. There are also some patients who have both internal and external hemorrhoids, i.e. mixed hemorrhoids. Hemorrhoids are the most common anal and intestinal diseases. The cause of hemorrhoids has not been fully clarified, and may be related to heredity, diet, bowel habits and other factors. 1. Internal hemorrhoids: the main clinical manifestations of internal hemorrhoids are bleeding and prolapse. Fresh blood after intermittent bowel movements is a common symptom of internal hemorrhoids. When there is no thrombosis, incarceration, or infection, internal hemorrhoids are painless, and some patients may have difficulty in defecating. 2. external hemorrhoids: external hemorrhoids main clinical manifestations are anal discomfort, moist unclean, sometimes itching. Connective tissue external hemorrhoids and inflammatory external hemorrhoids are common. If acute thrombosis occurs, it can be accompanied by severe anal pain, called thrombosed external hemorrhoids, the degree of pain is related to the size of the thrombus and the relationship with the anal sphincter. 3. mixed hemorrhoids: patients with mixed hemorrhoids may have symptoms of both internal and external hemorrhoids. Mixed hemorrhoids gradually aggravated, can be ring-shaped out of the anus, called “ring hemorrhoids”. If you can’t restore the hemorrhoids to the anus in time, you can get “strangulated hemorrhoids” or “embedded hemorrhoids”, which may appear edema, bruising, or even necrosis, which is often accompanied by severe pain. If you feel uncomfortable, you should consult a doctor in time to avoid delaying your condition or causing adverse reactions.
