[|Human|] my father, age 82, last summer taken to hospital had abdominal anuerism.  was repaired.  last week got weak and taken to hospital, scoped both ways no bleeding found but hemo was down to 84, they said his blood has not rebuilt from last summers operation.  was sent home 4 days ago, in hospital again today frequent bm with bloody stool , very weak, hemo now 65.  this number seem very low but I do not know what this number means.  they are giving him blood now.  I think he hs to be bleeding for this much blood loss?
[|AI|]  Hello, Your father is losing blood from the gut. If the upper and lower endoscopies are normal, the site of bleeding is the small intestine which is not visualized by these endoscopies. Normal Hemoglobin is about 14 gm/DL, and he required blood transfusion because he would have lost significant amount of blood. If he were my patient, I would get an angiogram done to determine the site of bleeding and stop it by embolization of the bleeding vessel. The other option is surgery if the bleeding does not stop. I hope he will get well soon. If you have any queries I shall be happy to answer.
