I was recently diagnosed in May as being pre-diabetic and have just started using a blood glucose monitor to help manage my symptoms better. I take kickboxing twice a week and I have been noticing that I get this fruity taste in my mouth and then today I actually became very confused, starting sweating profusely and shaking right during class. So, I tested my blood and it was a 5.0 which is not that bad. Anyways my instructor gave me a fruit box to drink and I immediately starting feeling better. I and very puzzled as to what is going on in my body. I was told to monitor my sugar levels because they are too high but then get episodes where it feels like my sugar is too low!???? Is this possible? I also get a tingling feeling in my fingers sometimes. Is this related? I am very confused. Any answers would be greatly appreciated. Thanks!
