hemorrhoids bleeding treatment,Analysis and treatment of blood in stool

    Blood discharged from the anus is called stool bleeding, commonly known as blood in the stool. It mainly includes blood dripping, spurting blood or blood in the stool. In general, blood in the stool visible to the naked eye often indicates bleeding in the lower gastrointestinal tract (especially the colon and rectum). The closer the bleeding site is to the anus, the brighter the color, which is the most common perianal disease.

    What to do with bleeding from hemorrhoids?

    It is generally believed that bleeding from the stool is caused by hemorrhoids, which is incorrect. Hemorrhoids, especially hemorrhoids in the first and second phases, so that blood is the main symptom. Hematochezia usually occurs during defecation, dripping or jet-like bleeding during and after the stool, and the blood does not mix with the stool. The amount of bleeding varies from several milliliters to tens of milliliters. Repeated bleeding can cause severe anemia. The diagnosis of hemorrhoids is relatively easy, but it must be pointed out here that clinically, anorectal diseases with blood in the stool, such as rectal adenoma and rectal cancer, are often misdiagnosed as internal hemorrhoids. Therefore, when determining the diagnosis of hemorrhoids, other diseases must be ruled out. It is necessary to perform routine digital examinations on patients with hematochezia. It is a convenient, economical, safe and accurate inspection method for routine inspections using disposable rectoscopes or anal mirrors.

    Blood in the stool is generally divided into bloody stools, tarry stools and occult bloody stools. The common causes of stool bleeding are described below.

    1 Bloody stool: usually from the lower part of the ileum, colon, rectum, and anus. The color of stool is bright red or dark red, and may be mixed with mucus and pus. Common diseases are: hemorrhoids, anal fissure bleeding. Hemorrhoids, hemorrhoids, blood in the stool sprays out during defecation or drips after the stool; anal fissures have less blood in the stool, but the anal pain is more severe. Rectal polyps are bleeding, the amount of blood in the stool is not large, the blood is attached to the surface of the stool, and sometimes the stool becomes thinner or has pressure marks. Dysentery, blood in the stool is pus, blood in the stool, frequent stools, and pain in the left lower abdomen.

    2 Tar-like stool: Black stool. Upper gastrointestinal bleeding is not vomited. The blood stays in the intestine for a long time. The hemoglobin in the blood combines with the sulfide in the intestine to form ferrous sulfide. The ferrous sulfide makes the stool black and shiny, like asphalt. The appearance of tarry stools indicates that the bleeding volume has reached more than 60 ml. But it should be noted that certain foods and drugs can make the stool black, which can be identified by the stool occult blood test.

    3 Occult blood stool: Any small amount of gastrointestinal bleeding does not cause stool color change, and only a positive stool occult blood test during laboratory tests is called occult blood stool. All diseases that cause gastrointestinal bleeding can cause occult blood in the stool, common gastric ulcer, gastric cancer.

    The rescue measures for hematochezia are basically the same as for hematemesis. Stay in bed quietly, reduce activity, observe the amount of bleeding, use hemostatic drugs appropriately, and send to the hospital for emergency treatment if syncope or shock occurs.
