Change in Fasting Blood Sugar Numbers

by Sweetgirl53, Jun 08, 2008 10:47AM
I was diagnosied with Type II Diabetes 2 years ago.  I am having a wide variance in the fasting blood sugar results each morning.  If I test just as soon as I get up my FBS is between 130-150.  If I wait about 30-45 minutes, shower and get dressed the numbers increase to between 170-190.  I haven't eaten or had anything to drink in this time period.  Is there a reason for this sudden increase?  Which number is my real FBS?  I stopped taking my Metformin when I was only testing first thing in the morning because my numbers were lower (and I couldn't remember to take it after eating something).  Now I wonder if I did the right think in stopping.  Should I go back on the Metformin and what numbers do I report to my doctor?

HI,
Even if you do not eat anything, the glucose made by the liver does cause an increase in your blood sugar. In addition the cortisol bump in early mornings cause many folks to have higher blood sugars then. So you have a few reasons for this rise.I think you should record the range in sugars you see and show all to your doctor. Based on the numbers you wrote I think you should discuss restarting the metformin with your doctor because they are not in the normal range. The best way to go with early diabetes is to get a hold on it quickly, and give it less time to do damage to your body so definitely talk about this with your doc.

Take care
