Low blood glucose

[ianstead]

I had really low bg on a very hot and humid night this week. Dinner at 5.30 with insulin taken and then I dropped to 5.2 at 2100 and I like it to be a little higher before I go to bed. So, I did what I normally do, and had 1/2 bowl granola which usually sorts it out until the morning. However, at 22.30 I dropped to 3.9 so I had an 18g carb carton of orange juice at 2400 I had dropped to 3.2 so I had 3 jelly babies and then I dropped to 2.6. I then removed my omnipod thinking that it was giving me insulin when not requested. At this stage I rang 111 for advice. My diabetic team were very helpful the following morning and suggested the problem was due to the very high overnight temperature, as I normally manage my diabetes very well. They have now given me a glucagon pen for my wife to give me a dose if I cannot do it myself. Thank goodness we have a good alarm system with libre 2.
I would like to ask if anyone else has experienced such a problem with high overnight temperatures?

I'm going to presum that you checked cgm reading against fingerprick ?
have had low readings with hot weather a few times, most of those was just the cgm readng a little lower than usual for me cgm usually reads a little lower but not a huge amount dsn has mentioned that they can read 1-2mmol out at times hence asked if checked via fingerprick. I've had on a few occassions with readings being VERY far out which abbot then replaced those free of charge. eg 3.9 on libre fingerprick 13.4.

compression lows are also a thing if leaning on that side at all for me, doesnt need to be any pressure on the cgm itself just anywhere near that area which can make it read lower.

first 24 ish hours of new sensor application can be a bit off too for that reason i tend to try avoid by inserting umpteen hours in advice (eg the night before). despite the quirks <3 the libre

Thanks for the reply. I always do a fingerprick test as well as I find libre out a few times. I also felt quite low on those readings.

My blood sugars always plummet when the temperatures are higher. Insulin can be absorbed quicker when it's hotter (https://www.diabetes.org.uk/about-diabetes/looking-after-diabetes/hot-weather).

In the heat/hotter countries, I tend to do my insulin a little later than usual and give a little less as 90% of the time it's what works for me, however, this won't work for everyone.
