After the doctors found blood in dad's stool last week, they discharged him from the hospital on Thursday and scheduled an upper and lower GI scope for today. After doing the upper GI this morning, his doctor came out and told mom that they had found the problem: a bleeding ulcer.
This explains where his blood has been going and his overall tiredness. He hasn't complained of any heartburn or discomfort in his stomach, but we've always known he is a tough old bastard!
He is currently in the Phillips County Hospital and will be there for a few days until his blood levels come back to a normal range and they get his ulcer medications figured out. We are very relieved to know it is something that is so easily treatable.
