Hot weather and BG going high

The general wisdom seems to be that insulin resistance decreases in hot weather so T1 are inclined to go low. However, my husband's seems to be doing the opposite. He's not unwell and he started a new insulin pen (Novarapid) just in case, drinking loads of water, increased his basal and following sick day rules for corrections but still very high ie 20+. It comes down overnight to something sensible and then rises with the temperature during the day. His control is usually really good. Anyone else experienced this? Thanks!
 
Sorry to hear about your husband’s diabetes throwing a curve-ball. It’s nothing it not complicated, confusing, and contradictory (to use Gary Scheiner’s memorable description)!

Many of us have been seeing lower BGs than we might normally expect, but some have also seen BG rises.

Sounds like your husband has taken good precautions (starting a new pen in case the old one was compromised in the heat), and considering other reasons such as illness.

Is this increased BG with higher temps something he has seen before? How long has he been living with T1?

Sometimes when diabetes behaves unexpectedly, all we can do is fire-fight the errant levels, and keep our minds open to other reasons for the raised BG.
 
Here’s another member discussing high BGs with the raised temperatures

 
Some people find their BG goes low in hot weather. Some people find it goes high.
My theory is that it depends how you feel in the heat. If you are comfortable, it is likely you will be in the low camp. If the hot weather makes you feel uncomfortable, the stress on your body will raise your BG.
 
He developed T1 (immunotherapy induced) in the spring of 2023 so this is his first really hot weather. He didn't experience this during the hot weather earlier this year, but then it wasn't as hot as this! Reassuring that it's just another of those infuriating diabetes things and hope for cooler temperatures next week.
 
Mon / Tues / Weds looks set to be much cooler. Hope his BGs settle back down pronto 🙂
 
I'm running high and have been since Thursday (the day after I got back from holiday). It's hard to know if it's the temperature or the fact I'm not riding quite as much/as consistently as I was doing over last (long) weekend, etc.

I'm definitely drinking less French wine and Belgian beer and also eating fewer croissants and pains-au-chocolat, and while the former may well have lowered my BG I can't see that the latter helps my theory at all 🙂

Just one of those things.

Sorry, @helli , doesn't work for me! I hate the heat but go low. Worst hypo ever was in a heatwave.
 
... and I love the heat and yet went high.

However, my youngest is off school today (and yesterday) with a sore throat/chesty cough so perhaps I was in fact brewing something that I gave to her, who knows.

She seems to be on the mend though which is the important thing 🙂
