Hi all, I haven't been posting here lately but I want to report a finding that may be affecting my CFS. I have had normal fasting and random blood sugar levels as well as normal HbA1c levels throughout the many years I've had CFS. However, recently I did a 2 hour glucose tolerance test which showed a high glucose at 2 hours and low insulin (less than 1/2 of the bottom of the range). So it looks like I have an insulin insufficiency. Looking back I see that 12 years ago I had a glucose tolerance test showing normal glucose levels yet insulin levels bouncing at the bottom of the range. So the low insulin occured first. This may explain why I always felt so fatigued on a low carb diet - not enough insulin to get enough carbs into the cells. I am waiting for my appointment with the endocrinologist. I am curious to see how insulin helps me, if at all. I don't think this is the cause of my illness by any means but rather a downstream affect of it. All this to say it may be worthwhile to get a glucose tolerance test (with insulin measured as well) and/or to buy a glucose meter and test your glucose at home.
