There are many people who think they have hemorrhoids when they find themselves bleeding in the stool, but in fact, blood in the stool is not only a symptom of hemorrhoids. For example, bleeding caused by ruptured varicose veins in the lower esophagus and bleeding from peptic ulcers can cause blood to remain in the intestinal cavity for a long time, resulting in a tarry, dark or coffee-colored bowel movement. There is also bleeding from the colon and lower rectum, which is bright red in color and closely related to defecation. Among them, hemorrhoid bleeding is characterized by the amount of blood discharged during forceful defecation, ranging from dripping blood to blood on hand paper after defecation, or in the form of jets. In the case of anal fissures, the amount of blood in the stool is small and accompanied by severe pain. In case of rectal polyp bleeding, blood contaminates the anal area during defecation, which is more common in children; in case of adults, blood in the stool is mixed with mucus and pus secretions, and the stool sticks become thin and smell especially bad, so special attention should be paid to whether there is cancer in the rectum and the lower colon. If there is urgency in defecation, blood and mucus in the stool, increased frequency of stool, and pain in the left lower abdomen, dysentery and enteritis should be considered first. In addition, in addition to blood in the stool, hemorrhoids can also have itching around the anus, mucus flow, perianal swelling and pain, and in some cases, something may come out of the anus after the stool. Specifically, these symptoms can be present in a patient alone or at the same time, so it is important to analyze the specific problem.
