Understanding chemistry of blood sugar readings

[Kaha]

I think like myself many of us might have some misconception about how the blood sugar readings change with time and duration of fasting . I am sure we all can get benefit if our own experiences and views are shared among ourselves . Through my personal observations while closely monitoring my readings at various times of the day , I concluded that :
1) The blood sugar readings are not dependent on the length of fasting time (it can be more even with more hours of fasting and vice verse)
2) If I skip some meals or remain totally hungry to get a better reading of sugar level , it may not happen . So sugar level at fasting has nothing to do with hunger status
3) Fasting sugar readings in the mornings are usually higher than readings taken at different times of the day (even though the time gap after meal during day times are much less than the time gap between dinner , sleep and fasting sugar test time )
Do you agree with me? May be you have other points to share?
Can a member with medical background explain these issues ?

The fasting is to get a background reading of how your pancreas/liver are working in tandem. The liver detects the amount of insulin and as it gets lower it puts more glucose in the system. Your body then has to process this glucose by raising insulin levels stopping the liver producing more until the glucose level drops and the insulin lowers. Now the issue with insulin resistance is that the liver cannot detect the amount of insulin as accurately and it sees what it thinks is a low insulin level and releases glucose. Hence your levels go up. Your body goes through this cycle constantly but is masked when there is food in our digestive system. Hence the fasting. Generally you will have an upper and lower fasting limit with the lower limit being the point the liver cant detect the insulin level any more.

So to answer your question: 1 yes agree depends where you are in your cycle. 2 as per 1. 3 not for me but many see this and is because when you eat your pancreas releases more than normal back ground level of insulin and so you over use slightly.
