Hi
During a routine BG check, I was diagnosed with high BG about 6 months back (early May 2008). At that time, I was overweight (75kg) for my height (160cm) and was not careful with my diet, under lot of stress at work and not getting regular exercise. My doctor put me on Metformin (500mg twice a day) and advised me on proper diet and exercise.
I lost about 5kg within 5-6 weeks by simply changing my diet and regular exercise (70kg by mid June). However, at the same time I began feeling hypoglycemic after everytime I took Metformin. So my doctor advised me to stop taking it and continue with my diet + exercise, and to also monitor my BG regularly.
Since then my BG has been tested regularly (every week) and it has been normal (around 6 mmol/dl). My HbA1c dropped from 13.7 to 7.3 in the first 3 months and is now 6.2 after another 3 months. In fact, I have lost a further 3kg in the last few months with regular exercise (67kg by mid Oct). I have also reduced the amount of food I eat at each meal especially the carbohydrates. I have cut out simple sugars from my diet completely.
However, for the last couple of months I have begun feeling mild hypoglycemic symptoms (nervousness, shakiness) especially a few hours after my breakfast, which goes away after I suck on a regular candy (2-3g sugar). Rest of the day I'm mostly fine although sometimes I feel a bit lightheaded after meals esp. if I had a bit more carbohydrates than normal e.g. an extra slice of bread.
My doctor thinks its nothing serious and my body is reacting to all the changes I have made to my diet and my weight loss etc. He says the symptoms are typical in people with insulin resistance and will go away with time. However, a specialist I saw seems to think it could be hyperinsulinism or reactive hypoglyecmia. I wonder if anyone has had a similar experience and could help me understand what I am going through.
