I've been noticing more over the past couple years a stronger correlation between my blood sugars--especially high blood sugars--and my moods. When I'm low, everything seems hard--it's not a good time to ponder, for example, doing an Ironman. But when I'm high, I can feel really depressed and easily frustrated, as well as sleepy (a symptom more commonly expected). I have noticed a fairly rapid improvement as my BG's return to normal, even before I know my BG's have come down. Maybe these mood changes were always there and I am just finally noticing how my BG's relate to them; or perhaps they are becoming more pronounced through the years. I'm not sure. Anyway, this post was prompted by a BG over 400, which I attribute to letting my pump run too low (air bubbles?) and also going on a BG testing strike of 4 hours. My basals also seem a bit off these days. I loaded up on a few units which, with my current insulin on board, should bring it down. These are the times that diabetes can really be a challenge for me, emotionally, even though I know it's just the BG picking on me. Fortunately, though, I will be able to shake it off with a long swim + run in the morning. Hooray for that.
(Note: BG=blood glucose, aka blood sugar.)
