Blood in the stool is one of the main symptoms of hemorrhoids, but you should not assume that it is bleeding hemorrhoids at the sight of blood in the stool, because many digestive tract diseases and systemic diseases can cause blood in the stool, and blood in the stool is one of the more common clinical symptoms. For example, the upper gastrointestinal tract ulcers and cancer; lower gastrointestinal tract small intestine diseases: acute necrotizing small intestine, pseudomembranous enteritis; colon diseases are more, such as colorectal cancer, ulcerative colitis, colorectal diverticulitis, rectal polyps, intestinal entrapment, Crohn’s disease, etc.; systemic diseases such as blood system diseases: leukemia, thrombocytopenic purpura, hemophilia, reocclusion, etc. ……, the number of diseases with bleeding stools is gradually increasing. Of course, it cannot be denied that internal hemorrhoids and anal fissures are the most common diseases that cause blood in the stool, while other diseases that cause a lot of blood in the stool, such as peptic ulcers and hematologic diseases, are relatively rare and easy to identify, so people with hemorrhoids usually think that blood in the stool is hemorrhoids and are used to this kind of bleeding without treatment. However, bleeding stools often conceal more serious diseases, such as the dreaded and common colorectal cancer. With the aging of the population, the gradual westernization of lifestyles and dietary habits, and the further pollution of the environment, more and more people are suffering from these diseases, so special attention must be paid to them. Therefore, in case of bleeding stool, do not conclude that it is due to hemorrhoids, but should promptly go to the hospital to check in order to “prescribe the right medicine”, otherwise, the wrong medicine is still a small matter, the consequences of misuse of the disease is unimaginable. For blood in the stool, children are very different from adults suffering from the disease. The most common is internal hemorrhoid bleeding, but it must be recognized that rectal cancer, rectal polyps, proctitis are also common diseases that cause painless blood in the stool, especially rectal cancer, more youthful, the trend of increasing incidence should cause us to pay sufficient attention to the high rate of misdiagnosis of rectal cancer, mostly because some clinical The high rate of misdiagnosis of rectal cancer is mostly the result of some clinicians and patients not paying enough attention to it; in adults, if blood in the stool is combined with pain, the most common one is anal fissure; in addition, anal cryptitis can also cause a small amount of blood in the stool with pain, but anal cryptitis also has other symptoms such as incomplete defecation, burning, swelling, mucus and always a feeling of stool, and it is sensitive to antibiotics.
