What's wrong with blood in stool, blood in urine, blood in urine?

Blood in stool and urine are two different symptoms, which may be caused by different diseases, among which blood in stool may be related to hemorrhoids, anal fissure, rectal polyps and other diseases; blood in urine may be related to urinary tract infection, kidney stones, prostatitis and other diseases. 1. Hemorrhoids are usually located inside or outside the anus. When feces pass through the anus, especially in cases of constipation or hard stool, the friction of feces on hemorrhoid tissue may lead to hemorrhoids bleeding. Since blood is mixed with feces, it will be manifested as bleeding in feces. 2. Anal fissure anal fissure can cause laceration and trauma to the skin or mucosa around the anus. When feces pass through the fissure, it may cause further damage to the skin or mucosa and bleeding. Rectal polyps are supplied by blood vessels on the intestinal wall. When the polyps are enlarged or abnormal blood vessel structures exist, these blood vessels may be easily destroyed, causing bleeding and eventually causing blood to be pulled from the stool. Second, urine blood 1, urinary tract infection urinary tract infection, bacteria invade the urethra or other urinary tract tissue, leading to inflammation, inflammation will cause congestion of the urethra and other urinary tract tissue, and make blood vessels become fragile, easy to rupture, resulting in urine blood. 2. Kidney stones When kidney stones move in the urinary tract, they may rub against the urinary tract wall or produce irritation, resulting in damage to urinary tract tissue and bleeding. These damages cause blood to appear in the urine, showing symptoms of urinary blood. 3. Prostatitis causes congestion and inflammation of prostate tissue, making prostate blood vessels dilated and fragile. In this case, blood vessels in the prostate tissue may rupture as urine passes through the urethra, resulting in the appearance of urine blood.
