Mom went into the hospital the beginning of March with a GI bleed. She was in there 4 days. They gave her one unit of blood while in the hospital, then discharged her, with orders for another blood draw to check her blood levels. She was still at only 8.7, so they gave her another unit of blood. I expected her perk right up after that, but she hasn't. I've also noticed that her memory is failing since this happened (she does not have Alzheimers or memory issues). I understand that red blood cells carry oxygen, and oxygen is important for brain function - my concern is that this could be permanent. Mom is 82 yrs old and has been declining more rapidly since she broke her hip last September. Any help would be appreciated.
