After a recent blood test that showed elevated fasting glucose (110mg/dl) and elevated triglycerides (~335mg/Dl), I got myself an Accu-check glucose tester and started regular testing to try to figure out where I'm at in terms of insulin resistance etc.
Several times now I've had a set of results I don't understand. Today for example, I tested my glucose level right after waking up and I got 106mg/dL. Feeling this was a bit high (my average over the last 7 days is 100) I drank a bit of water (as I hadn't drank any overnight) and re-tested 20mins later. The second test result was 96mg/dL.
Same thing happened three days ago with 108 and 109 after testing twice immediately after waking up, then 97mg/dL 25 mins later (again after having a bit of water as I hadn't drank any during the night).
Which of these results is more relevant/accurate. Is the first one skewed by slight dehydration, or is the second one less relevant because of either the water or the ~20 mins of activity?
For context, I suspect that the elevated glucose and triglycerides stem from both my sedentary lifestyle and daily alcohol use. My diet on the other hand has been quite good and I've generally avoided sugars and high GI carb for almost 10 years now. For the last 10 days I've stopped drinking and am in the gym almost everyday alternating between weight training and ~30 mins on a stationary bike.
Edit 1: As Graham Chiu pointed out, water intake in the morning should not skew my results. Although, I'm unclear whether not drinking enough water on a given night could increase the result the following morning?
The other question is, can there be a ~10+% drop in blood glucose after 20-25 minutes of light activity in the morning? Or should I be chalking this up to coincidence and meter error margins (even though back-to-back results are quite consistent)?
