my 5 yr old nephew has blood clot issues. He's been hospitalized before. His father and mother are obese. My nephew is also already obese. Its hard to watch your family members' health decline when you feel you are privy to better information but people usually dont want to hear it or wont understand it or wont go through with it. (Yea, like primal habits are going to start popping up in my brother's household 300 miles away because I might mention a better diet to him.......yea not gonna happen) Im sorry to hear about your family member, I have no knowledge of what might be causing this but thought I would share.
