I rang the doctors yesterday and my fasting glucose is satisfactory, Don't know the level, I have a doctors appointment next week so will find out then. I've been thinking of what could have caused this irregularity in blood glucose. I didn't mention in my first post that up until 2 months ago I was receiving the Zoladex implant for 8 months, I didn't think this was relevant at the time, just another health issue. But looking into it further, one of the side effects is high blood sugar which rarely can cause diabetes. Now I'm not saying I'm diabetic, but maybe this implant has interfered in some way. Has anybody else had this sort of problem with medication, and would this eventually wear off or could it be a permanent issue?
