My brother has some type of a hernia (can't remember name of it) that has made a tear in the intestine. His surgery was postponed due to his blood not clotting. Can anyone tell me what would make your blood not clot? Last year, he was having a problem with his white blood cells being too low. Not sure if that has anything to do with the blood not clotting. Anyway, if anyone can help, I would appreciate it very much. Thank you.
