get a tester and monitor and above ^^^ classic is offering help.
From what I understand (and I am diabetic), if you are not diabetic then you should not be getting any sugar spikes. Sugar spikes happen when your brain signals that your blood sugars are too low and your kidneys do a sugar dump, supplying your body with a sudden supply if sugar which in turn spikes your blood sugars. If you are not diabetic then you sugars are controlled by your bodies natural insulin and therefore your sugers do not tend to go high or low and you won't get any sugar spikes.
I think alot of it has to do with how long you fast before a blood test.
Sounds like doctors alright..
I am diabetic and have studied into this extensively. I'm an not a doctor, but if you want my opinion, message me the particulars and I'll give you my take.
