    I was just curios if weather had an affect on diabetics blood sugar

    Also is insulin as efficient when it's really hot as it is right now. Can't complain though I suppose!

    Shout out to all my fellow diabetic today, keep smiling :)

    Heya, yes the weather certainly does affect your blood glucose levels. I find I need less insulin as my body burns it up a lot quicker, whereas in the colder weather I need more.

    Take care with your insulin storage too, keep it somewhere cool :cool:

    We've gone the other way! Higher bloods and only 1 hypo in nearly 3 weeks.

    Hotter weather or end of the honey moon period, I'm not sure but things are looking up at the min

    Its a real Dilemma, i struggle to keep control of my blood sugars as it is! Perhaps closer monitoring of my BS will ensure the best possible outcome.

    On my last two fishing trips in hot conditions I noticed that my BS level went from 6.1(at 9.30am two hours after breakfast) to 8.2 at 12.30 before lunch and with no snacking between times.

    I can definitely go hypo more quickly when it is hot, although usually very stable, and I need to take less insulin. Is it the heat or do I eat less and have more salads?

    If you are adjusting your insulin for meals, then eating less should not be a problem. If you are on basal dose only, or fixed doses, then it may need to be adjusted.

    it may just be that in warmer times, you are more active and so use up the bg at a faster rate,

    Mine definitely goes down during hot weather, went to Turkey last year was in the 90's all week perfect to slightly low bs on all inclusive too (didn't go mad tho couple more ice creams perhaps!!) I think I need to move to a warmer climate for my diabetes that's my excuse anyway

    Yes, temperature does impact. I find usually I have higher BGLs in heat and lower in cold temps. But also I don't tolerate heat and can tolerate cold better. I physically feel sick if I'm too hot.... I think my body stresses from it and that's why I get the higher BGLs in hot weather.

    i'm not a fan of hot weather, as i sweat a lot, i'm not overweight either and have had type1 for 40yrs, now 55. hot weather suits darker skinned people whereas i'm very fair complexion. insulin doesn't keep very well in the heat either. as a tv cameraman, i've travelled the globe more times than most people have had hot dinners. and have worked in some very hot and inhospitable places. i've also found that the insulin doesn't seem to absorb in the body properly in extreme heat, causing my bs's to be high a lot, it's difficult day to day anyway to keep sugar levels at a sensible level unless you're sat at a desk fiddling with a computer all day then there is no excuse not to have good sugar levels.

    Hi, Mark.

    My personal experience is that warm/hot weather tends to lower my blood glucose levels ... sometimes quite dramatically (I 'clapped out' earlier today and required my wife to pick me up from the floor and put me onto my hospital bed ... the bed is at our home, not in hospital). This is because heat potentiates the effects of insulin, which means that it makes insulin work more efficiently. (This is one of the reasons that SOME people experience hypoglycaemia after having a bath or shower.)

    I think the impact of weather on blood sugar is really more pronounced in those who are injecting insulin - the causal link being increased temperature = increased blood flow to the skin (& injection sites) & therefore more effective/efficient insulin absorption. Or, because your diabetes may vary, increased temperature = less blood flow to the skin, because your body isn't working to try & keep you warm (think shivering) & therefore less effective insulin absorption. Bodies are so contrary!

    Hi dehydration is the worst problem for me in hot weather....Can't seem to drink enough water. Interesting to read the info about skin temperature etc.

    Sorry I should have written...that I'm on Lantus at night 44 units and Novo Rapid according to carbs in meals.
    bg's go up and down and have allergies sensitivities to the ingredients in Insulin. NO point talking to doc about it though.
