Hot weather.

just wanted to post and share my experiences of a really hot holiday. I had suffered in the UK when it got hot and for the first time in my life feared going on holiday where it was really hot. The holiday temp. ranged between 30 & 40 in the shade and considerably hotter in the sun. I hope this will help anyone else who has had high BG readings when hot prepare.

First experience was that the first two days my BG was about 1-1.5 mmol above what I would consider my norm. But that normalised and after about three days I found that in general - nothing to do with food - my BG maintained good control. I put that down to being tired and no exercise on a long journey.

There were some problems though. The morning DP was much worse and longer than in the UK. I am not sure about how this DP thing works. On some days I had no breakfast at all - I was milling around - it was really hot and my BG maintained - no DP. On other days same thing but a near zero carb breakfast - within an hour I was +2mmol and difficult to get down within four hours.

Throughout the holiday I had to be really careful on what I ate. On a couple of days in the afternoon - no lunch - I was able to eat half a mars ice cream, my only holiday treat and little impact. Aside from that - didn't even have berries for desert - too high carbs.

Red wine - no help on DP. Tried a glass with dinner every evening. Pool did help sometimes - but not as well as I had hoped with DP. Afternoons and evenings, regardless of heat were fine.

BTW - since apply skin tac wipe with Libre - no plasters - two week in sun, sea, pool - no problem at all.

This is very interesting - I was just on a cruise which went to Iceland and on a whale watching excursion in choppy and extremely cold waters out in the sea I absolutely froze, and this was in July. I was violently sick that evening and had to go to the infirmary. The Ukrainian doctor knew I was Type 2 strict diet controlled and her first question was had I been either very hot or very cold. I told her about the trip, during which I felt as if my body was closing down as I got colder to which she replied that extreme temperatures are very bad for Diabetes and my sickness, high numbers and severe joint pain was due to that fact. She also said that most UK doctors would not believe this ! I was well after 24 hours and on returning home a South African doctor friend told me EXACTLY the same, and made the same comment, albeit quietly and under her breath given she is a doctor in the local hospital ! I am off to Australia next February so now will be very careful indeed! I am so glad I now know this - no medic has ever told me this ! Thought I would pass the info on for what it is worth.

Very interesting. All I would add is that it might be more to do with the transitions. When I came back to the UK it took three days for my BG to go up then down again to normal levels - and it was not warm. I wasn't expecting that as I was certain that the cooler weather would just keep my BG constant.
