Patient's question:
NoDoctor's answer:
Hello, in order to resist the invasion of bacteria and viruses, the lymphoid tissue in children's bodies becomes highly active. The lymphoid tissue in the rectum, colon, and even the lower part of the small intestine clusters together. Some lymphoid follicles are relatively large, protruding from the submucosa of the intestine and arranged neatly and densely. The more prominent follicles near the anus are often subjected to friction from feces and compression from intestinal wall contractions, which can cause small amounts of bleeding to seep out, sticking to the feces or even flowing to the anal opening. This is the reason why children occasionally have blood in their stools.
