Second, hemorrhoid bleeding, dry stool can cause hemorrhoid bleeding, mainly blood in the stool or bleeding after the stool, mainly fresh blood stool. Third, bleeding from intestinal tumors, which can be accompanied by changes in bowel habits or changes in the thickness of the stool. Fourth, bleeding caused by blood disorders may be accompanied by a decrease in platelets. Judging from the symptoms is not very accurate, and further clinical examination is needed to confirm the diagnosis.
