My 80 year old father fainted last week in the middle of the night going to the restroom. Mom got him to the emergency room and they determined that he was 50% dehydrated. They put him on IV fluids to plump him back up, and he was kept just to be on the safe side. 36 hours later when my mom thought he would be discharged, she arrived at the hospital to find he was getting blood. He ended up with 3 pints of blood in addition to the IV fluids. How the heck does one need three pints? They kept him a couple of more days to see if he was bleeding somewhere. He got a colonoscopy, an upper GI, an MRI (he has Parkinsons) and all tests were negative. He does have vertigo, and has meds for it, but they say his blood pressure is dropping when he stands up. It is frustrating when there is obviously a problem, but no clear cut reason can be found. Have any of you had elderly parents with dizzy spells, sometimes several a day? He is still having them after being discharged from the hospital. He has an appointment with the neurologist next week and I am hoping for answers. My parents are supposed to be going to visit my D at school in 10 days (my dad has never been) and we are playing it day by day on whether he can make the trip or not.
