Have you lost a glucometer because the case is so bulky?

Two times I’ve lost a Freestyle Flash glucometer that comes in a case that looks a lot like a billfold. One time it was in LAX where I highly suspect it was pickpocketed because it looked like a wallet. I lost one again last week. I’m not sure it fell out of my pocket or was a replay of the LAX incident. Has this happened to anyone else? Do you put your glucometer in a a different case? How do you carry it since glucometers aren’t the easiest to carry in a pocket?
