Wow! I never knew about this! Granted I'm not on the pump anymore, but I'm always learning new things on here. (:
Brian, when I was on the pump, I was always very, very high on plane rides. I thought it may be cabin pressure or something. (I wasn't that high sitting still for the same amount of time in a car.) But, the doctors always acted like I was crazy. Have you heard anything about that?
hi Sarah. usually, when people are under a lot of stress or pressure, their blood sugar goes up. it's the same kind of thing your body naturally does in response to adrenalin, your liver dumps sugar and your body becomes more insulin resistant, allowing your blood sugar to rise to assist fighting off the attack or whatever. I fly a lot and it's never a surprise to me that my blood sugar rises when I am scared, or stressed, or both.
HUGE magnetic fields can break the minimed pressure transducer (internal electronic part). not the kind of magnetic fields that you will find on any roller coaster ever made anywhere, but more like when you are lying in the center of an MRI. always take off a pump near an MRI.
If a ride causes you to feel significant additonal forces, like the round thing that spins and sucks you against the walls, it's possible (though very unlikely) that your pump could deliver insulin without warning. I thnk it's a very small risk and I have never had any problems. plus I like rides and the fun!
