I wrote in the "Today's Ride" section of this forum last week about getting quite serious symptoms of low blood sugar. Though not a diabetic I bought a blood glucose monitor and tracked my readings for a few days and all seemed OK. I have now been to see the practice nurse at my surgery and had a good, helpful talk. Reading my readings it became apparrent my blood sugar sits at the upper end of "normal". I can understand this. My diet is fairly high in sugar, and I have been overdoing the carbohydrates in the mistaken belief I need lots of carbs to fuel my cycling. Now, my body has adapted to the higher blood sugar levels and that feels normal to me. It seems what has been happening is that when my blood sugar drops to what is generally considered a normal level, my body, so used to the higher level, is responding as it would in the event of a proper hypo. hence my feeling so bad. That's the cause. Now the treatment. I have to bring my average blood sugar levels down, even though my body says I am low. Essentially I have to just live through the symptoms until my "sugar thermostat" resets itself. A bit like quitting smoking. I have reduced sugar in my diet, and reduced the carbohydrates. I rode 30 miles this morning and had a really good ride. The other thing is the Lucozade powder sports drink I have been using is also very high in sugar. I just used water with a drop of squash this morning for the flavour. So it is nice to know that all I need to do is make adjustments to my diet. It will take me a while to get it right but having something positive to aim at is a great boost.
