    I have noticed my BG levels have been up a bit over the past few days coinciding with the hot weather in the UK. I've had next to no carb but fasting levels are high fives where I'm used to mid to high fours, and I had one post-meal reading of 7.3, which is very high for me (not been over six for a while). Can't think what it is other than the heat - I've been outside a lot digging mainly - lots of sweating and water intake. I know high temps are one of the things that potentially affects BG up and down, but I don't recall this affecting me before (although I only have last summer to go on).

    Any ideas?

    The heat definitely affects my sugars - much less predictable in the warm weather. I find I get my hypos than anything else

    I’ve been noticing the same. I also have gone to the gym recently and in sone pain so wondered if that was a problem

    but yeah, readings into the 7s and staying high for 4+ hour after eating which is unusual for me outside of fatty carbs food. Also high 5s dating where I’d normally be similar to you

    We shall see.
    Just been out for a 10 mile cycle ride (first for over 6 weeks) and I have the predictable spike.
    Now to see how quickly it comes down.

    There are loads of things that affect our blood sugars including heat.
    But the effect varies because we are all different. Some of us find heat results in higher levels but many of us find it causes lower levels.

    it is another example of what amazing machine the healthy human body is in being able to regulate our blood sugars.

    For the last few days I've been having lows more than highs. It's so aggravating - chasing highs, treating lows. Someone should use that as a hook for a tune.

    My nurse has told me the heat will make your body process any glucose in your system quicker. For me it raises my blood glucose by a quite a bit. I am struggling today and have had to take 2 extra insulin injections. I wonder if the people who have hypos process their food quicker and then as it’s not lasting and keeping them stable causes a later hypo. For me it just seems to go high and stay there! I also have frequent hypos when it drops to about zero in the winter. Walking my dog when it’s snowing has become a bit of a problem for me!

    Heat increases my blood sugar readings. About 5 days of 35 degrees at the end of June 2019 pushed my blood sugar values to 9 mmol/L after breakfast when on a normal day the values would be below 7 mmol/L. Less heat, 30-32 degrees, results in a smaller increase typically 6.5 to 7.5 mmol/L.
