This post is about my grandpa because the doctors cannot seem to figure this out. Maybe you can help:
He first complained of dizziness when standing several weeks ago, and he was so dizzy that he couldn't walk more than a few feet. The doctors couldn't figure it out. Monday he went to the hospital where they drew blood and found his hemoglobin level at 3.2 with a normal white count. They presumed cause was an internal bleed and then they did a chest and cranial cat-scan and/or CT scan (idk which one). No bleeds were found in those. Then they performed a endoscopy where they found what may or may not have been a recently healed bleed (it could have simply been irritation of the large intestine).
Whilst they were doing all of these tests they were treating him with blood and plasma transfusions. They stopped this yesterday and are keeping him for observation, in order to find out if the bleed is still going. They still don't know where the bleed is or was and if it was a bleed at all. If there is a bleed the doctors have determined it is NOT from any sort of blunt force trauma or fall.
He's 76 years old, living a sedentary lifestyle. He was diagnosed with congestive heart failure two months ago. He had congenital heart disease for many years before hand. He has been obese ever since he can remember and has had diabetes since he was 40. He also had unchecked and untreated hypertension for what he assumes to be about 20 years, and now he takes blood thinners to treat it. He has been taking diuretics as well. I do not know his medications for diabetes or heart disease / heart failure, but I am pretty sure he is taking something for them.
What caused this internal bleeding?
