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?
