Curious question

I am telling you type 2, and I usually stop fasting the rest of the day.
But, lately I have gone very often with several days of stay in Barcelona, ​​(I live in Ordino - Andorra 1,400m), as the days of stay in Barcelona VAT passed giving less amount until I place myself in the last days to 105 incredible thing inMi, this has happened to me in the different times that I have lowered and at the time I returned home (Andorra) the next day again to 127 - 132.
Will it have something to do with the height at which I usually live ???

It's curious, yes.In height they say that more glucose is burned, but the blood carries less oxygen and what you eat takes more to digest, complicating the action of insulin.

In theory it should be the opposite of what you say.
