Fasting numbers creeping up….

Hi,
I was first diagnosed in mid November – my fasting BG number at diagnosis was over 300. I immediately began exercisig every day, changed my diet, am on 2x500mg Metformin, and have lost a bunch of weight. My fasting numbers steadily decreased, and seemed to level off in the mid
90’s. My liver function tests, triglycerides et al made remarkable improvements in a very short time, and in short, I was feeling very good about an extremely fast turnaround.
The past 2 weeks, however, my fasting BG numbers have been steadily creeping up, with a high this morning of 114. I have religiously maintained my diet and excercise regimen – no spurges – and can’t think of anything that would have changed,
My question to the group – since I am a newbie – is this a bad trend? Or are there some cyclical ups and downs over a period of weeks that are to be expected, especially at this early stage of trying to get things under control?
Thanks,
Phil
