Patient's question:
I have an itchy lower body, and my underwear is always yellow. What's going on? Why is there blood in my diarrhea?Doctor's answer:
First, it's necessary to determine whether it's upper gastrointestinal bleeding or lower gastrointestinal bleeding. If the stool is black and dark brown, this indicates upper gastrointestinal bleeding, commonly associated with conditions in the esophagus or stomach. If the stool is bright red, it is usually indicative of bleeding from the intestines or anus (if there is significant upper gastrointestinal bleeding, a large amount of blood loss may also result in bright red stool). Based on your description of diarrhea with bleeding, it is likely bleeding from the anus or intestines. If there is no significant pain, the possibility of rectal polyps is relatively high; if accompanied by a heavy or dragging sensation in the anus, or if there is prolapsed hemorrhoids, it is likely hemorrhoids; if accompanied by anal burning pain, the possibility of anal fissure is higher. It is recommended to visit a colorectal specialist for an anorectal examination or a rectal scope examination.
