My FG reading was 7.2 having been 7.4 at the weekend. I am finding this weird as for 2 months I have seen my twice weekly FG readings at sub 6.0.

I am wondering whether this was because I had late nights and early 'ish mornings both times in combination with late night eating = so less than 7 hours between last eating and FG test plus tired body. Whereas the 2 months of sub 6.0 readings were all on a good 11-12 hours of fast.

* Anyone have any views on what effectively constitutes a FG time period? 6 hours/ 8 hours/ 10 hours/ 12 hours etc ?

* Also anyone have any suggestions on why this week I am higher by a good 15-20% over the FG average of the last two months?

I have read the 'dawn phenomenon' stuff but was wondering if there are any other theories on this FG weirdness!

Any opinions on either/ both questions much appreciated.
 
Hi. The dawn phenomenon i.e. overnight liver dump can be affected by many things which will always be difficult to define. Personallyl I never measure my sugars in the morning but always 2 hours after a meal. I rely on the Hba1c to give me some idea of how I'm doing' on average' and the 2-hour test to indicate which foods affect me most. I was told by a phlebotomist once that the fasting test time should optimally be between 10 & 12 hours.
 
Hi

I'm with Daibell, it seems there are so many influences on the morning read - DP, time went bed, time last ate, when last ate. I just don't bother.

I do morning fasting tests only very rarely to see if anything is changing. Otherwise I test 2 hours after eating like those who replied above. However, I know that if I eat within 2 hours of going to bed, I get higher fasting readings.
