Jumper's boyfriend was with us in Chicago and both Jumper and her boyfriend J. took their blood pressure twice at (I think) a K-mart with a blood pressure pump. Jumper's was good. J's was really high for a kid his age...something like 160/90. He's very thin and athletic and tries to eat healthy. I wonder if the pump was defective. Anyway, they came back to the motel room and he was a little worried. I told him just to make sure his mom knew and not to stress over it and he seemed fine after that. I am wondering what could cause high blood pressure in a young athlete who eats pretty healthy and has no fat on his body. Anyone have experience with this?
