Blood in the stool is the most common symptom of hemorrhoids, and many people who have blood in the stool think that they can tolerate it or use some medicine and it will pass, so there is no need to “make a fuss” about it. In fact, blood in the stool is also a sign of no less than a dozen anal and digestive tract diseases, so don’t be negligent and miss out on your condition. We can make self-judgment based on the way, amount, color and accompanying symptoms of blood in stool, so as to make timely and reasonable treatment for them. Among intestinal tumors, rectal cancer is most similar to hemorrhoid bleeding due to its low location. Blood in stool is bright red and attached to the surface of stool in the form of drops, but most of it is mixed with mucus and dark blood clots in the blood or stool, accompanied by bad odor, and is persistent, accompanied by anorectal cramps and general wasting in the advanced stage, increased frequency of stool, thinning of stool sticks, and alternating constipation or diarrhea. If the stool is tarry or black, the bleeding site is mostly in the upper gastrointestinal tract, that is, the stomach and duodenum are most likely to bleed. If the blood is red in color, it is more likely to be bleeding from lower gastrointestinal tract disease. However, if the upper GI bleeding is large, the blood can also be red in color due to the short residence time of the blood in the GI tract, which needs to be noted. Hemorrhoids are the most common cause of blood in the stool. This kind of blood in the stool occurs during or after defecation, the blood is bright red, the blood does not mix with the stool, it comes down in drips and drops, or it is also ejected, the amount of bleeding can be large or small, it can stop by itself, and some of them also show a certain periodicity. Some patients have small lumps protruding outward from the anus when straining to defecate, but there is no anal pain. One thing is for sure, if the blood comes out in jets during defecation, the diagnosis is basically hemorrhoids. Blood in the stool caused by anal fissures is also more common in clinical practice. The blood is bright red, dripping out or wiped with hand paper, and unlike hemorrhoids, there is often severe anal pain after defecation. Rectal polyps, blood in the stool in children is mostly caused by these diseases. Blood in the stool caused by polyps is bright red, painless, blood does not mix with stool, some patients carry grooves on the surface of the stool, and polyps growing to a certain length can come out of the anus with the stool. Ulcerative colitis, dysentery and other diseases can also cause blood in the stool, and most of the blood in the stool caused by these inflammatory diseases of the colon is mixed with mucus or pus and blood, and is accompanied by lower abdominal pain, fever, frequent stools, and posterior urgency, and other symptoms, which are common in adults. In addition, some rare diseases, such as intestinal typhoid, intestinal tuberculosis and intestinal loop, may also cause blood in the stool. Systemic diseases such as leukemia, aplastic anemia, primary thrombocytopenic purpura, hemophilia, disorders of coagulation mechanisms, collagen disease, uremia, and certain rare infectious diseases such as plague and typhus can present with blood in the stool. However, in these diseases, blood in the stool is only a part of systemic bleeding, and blood in the stool is accompanied by bleeding from other parts of the body, so it is not difficult to identify them. Therefore the symptoms of blood in the stool should be seen promptly for early examination, preferably immediately at the time of bleeding, so that the diagnosis can be more accurate and targeted treatment can be applied. Although the incidence of hemorrhoids is high, but if you can actively prevent the cause of the disease, it is possible to prevent the problem before it happens. 1, actively participate in various physical exercise, to enhance the body’s physical fitness, and maintain an optimistic mood. 2, eat more vegetables, fruits, do not read a book when defecating, do not squat for a long time or excessive force, a glass of cold water in the morning to help prevent constipation. 3, avoid excessive fatigue, correct poor posture, work and rest.
