Hello Blood in stool is a matter of concern. Not passing of stool can lead to hardening of stool in colon and passing of hard stool can injure rectum and anal canal which can manifest as bleeding on stool or hemorrhoids and fissure in Ano. In my opinion you should take stool softeners like liquid paraffin or laxatives like lactulose to avoid constipation and facilitate smooth passage of stool. you should take dietary fiber supplement or lots of fresh fruits and vegetables in your diet which increases roughage and stool content. In my opinion you should consult a gastroenterologist for detailed examination and a battery of tests like liver function test and coagulation study as well as hemoglobin estimation to assess amount of blood loss and an endoscopy if need be. if you lost significant amount of blood than you may require iron infusion or blood transfusion. Hope I could answer your question please feel free to ask for further clarification, I will be happy to help you. Best wishes
