Blood in the stool is not a big problem, but if treatment is not carried out in time, it may cause aggravation of the condition and lead to the possibility of anemia. Bleeding in the stool is considered to be related to the following conditions and can be treated in a targeted manner: First, it may be related to anal fissures. This is mostly due to the bleeding that occurs when the skin around the anus is torn by dry, hard stools, which are not large, bright red in color, and accompanied by severe pain. Secondly, it may be related to hemorrhoids. When hemorrhoids have an acute attack, there will be local swelling, itching, pain and bleeding, and the fresh blood does not fuse with the stool, and long-term untreated bleeding will make the bleeding more and more. In addition, there is also the possibility of anal sinusitis, which mainly causes swelling and pain in the anal area as well as blood in the stool, and may be accompanied by abnormal discharge. Therefore, once the blood in the stool occurs, you should take appropriate treatment measures in a timely manner.
