| I've been type 1 since 1965, so I think I've just about seen it all--this summer is my 37th with diabetes, 40,000+ injections later. If there was any kind of predictable effect between blood sugar and temperature or seasons, I'm sure I would have noticed it by now, and I have not. But, being the voice of long experience, let me just say this--your insulin requirements (and therefore your blood sugars) WILL go up and down in cycles, seemingly at randon, that may last for days, weeks or sometimes months. It has taken me MANY years to figure this out, and no doctors will understand this fact. I am now 3 weeks into a cycle that began with constant lows. After 3 days of battling readings in the 60's, I admitted there was a pattern setting in, and reduced my base dosages--my basal by 1 and my dinnertime bolus by 3. I'm back in the 90's now and just waiting until the readings begin creeping up to signal me that this cycle is over and I'm back to my previous dose. It also happens the other way--I'll go several days, with no sign of illness, where my readings creep up to 200. then I know to add a unit or 2 at a time until I'm back around 100, but watch always for lows, signaling that I must reduce the doses again. This is frustrating and never (to me at least) explainable--it does not seem to have anything to do with the weather, my diet, activity, emotions, job stress, home life or weight gain or loss. It 'just happens'. Shrug... My advice--always be on the lookout for these persistant patterns, roll with the changes and then keep a close eye for the cycle to continue to change.
