When is the best time to check your fasting blood sugar in the morning? Should i

[Rasel Ali]

A: The query is absurd on its face. “Fasting” means WITHOUT EATING ANYTHING FOR AT LEAST EIGHT HOURS - so the answer is OBVIOUS. First thing, upon waking, before doing ANYTHING - is the “best” (if not the ONLY) time to do a FBG (Fasting Blood Glucose) test.

It is ALSO important to not be very active beforehand - because when we become active on an empty stomach - our glucoregulatory system RAISES BG - to fuel that activity. So don’t go for a run before the test - you’ll get a false high. Well… it’s a real high - but it’s NOT valid as a FASTING test. Just as eating before the test invalidates the fasting status of the test; that would be a post-prandial test.
