[|Human|] 50 yr. old boyfriend had blood in semen yesterday and afterwards had blood in stool.  todays stool had some but less blood.  hes trying to blow this off, since he had blood in semen years ago and docs could find nothing wrong.  hed been in truck driving orientation for 2 weeks prior (sitting/driving/riding constantly) and his back (which has several disks with problems) was hurting him badly.  Am trying to find answers.
[|AI|]  Hello really appreciate your concern for your boyfriend. Blood in semen and stool is a matter of concern. Blood in stool might be related to Fissure in ANO, Hemorrhoids, Colonial sinus or coagulation disorder and many other causes. I would advise him for a battery of investigation like CBC particularly hemoglobin to assess amount of blood loss, Liver function test, blood coagulation profile, blood sugar and urine culture test. In my opinion he should immediately visit an emergency care for physical examination, per rectal or photocopy examination to establish a diagnosis. I would advise him to avoid constipation by taking laxatives like liquid paraffin or lactulose 30ml at bedtime. Ask him to haveve lots of fluids which will help by flushing off the urogenital tract and clears the mild degree of infection. Encourage him for stretching exercises and get an MRI done for disc problem. Please write back to me with all the reports I have advised so that I will be able to tell you more precisely. Best wishes
