high blood sugar is a sign of diabetes and peeing alot is also becuase extra sugar the blood doesn't use isn't able to convert into glycogen because insulin isnt produced, therefore the excess sugar is peed out. go to ur GP and test for sugar in ur urine which will be a sure sign of diabetes. in the meantime look out for signs of tiredness during exersize as if u have diabetes u wont have a long term glycogen energy store which converts into sugar when u exercise. when u exercize u will also need to feel like u have to eat snacks to prevent the sudden blood sugar loss u feel. if this is you go to the docs as these are signs of diabetes and i am studying it at the moment in detail.good luck hun! id say go docs for peace of mind at least remember nothing could be wrong yet!! xx
