If the patient has been bleeding in the stool, he or she should go to the hospital in time and choose a public hospital where the anorectal specialist will perform relevant tests to clarify the cause of the bleeding. If the bleeding is caused by internal hemorrhoids, and if the bleeding volume is large, long-term blood in the stool may lead to serious anemia, and surgery is needed. If the bleeding in stool is caused by colorectal tumor, radical colorectal tumor surgery should also be performed for a limited period of time, and the next treatment measures should be decided according to the postoperative stage of the tumor. In clinical practice, there are many cases where blood in stool of tumor is mistaken for blood in stool of hemorrhoid, and the treatment is delayed by self-medication. There are also some patients with severe blood in the stool of hemorrhoids, which can lead to anemia and even hemorrhagic shock, endangering the patient’s life. So the most crucial thing is to clarify the cause of the blood in the stool and then take the appropriate treatment.
