Glucose Levels Rise during Cold Weather?

Lately my glucose levels have consistently been a little higher than usual without significant changes to my diet, exercise, sleep habits or stress levels. Several friends who are diabetic tell me that cold weather makes their glucose run higher and that their doctors tell them that experiencing cold raises blood glucose. I don't see my doctor for another month but I will ask her when I see her. I'm just curious if anyone here has been told this or had this happen to them. If there is truth to this I would really like to know why it happens.

Cold weather has always raised my blood sugar levels. I just raise my insulin dose just a little. Have been a type 1 for 30 plus years

I get cold faster and hot faster than I used to. That got worse when I lost weight 6 years ago. It does not seem to affect my readings.

I live in New Hampshire where it gets very cold, and sometimes spend quite a bit of time outside. I've not noticed any significant changes in my BG due to the cold, I have, however noticed I get cold faster than I used to, but that could just be an age thing. In the summer I've seen it going up slightly if I stay in the heat for very long and I have much less tolerance for sun or heat. I'd definitely check with the doc if the numbers go too high. Heidi

I get colder, faster too. I attributed it to my weight loss as I used to get cold very easily in my younger, skinny days. Now I suppose that age plays a role too.

I don't know if it's just extreme swings in the weather. Heat can cause it to rise, and I have heard other members say cold does the same. Maybe it is our bodies trying to work harder to stay warm (or cool)? That is a form of stress on the body that we may not realize.

That must be it. I haven't noticed the heat having that effect on me. Another possibility is that I don't drink as much in colder weather as I do in hot weather. I know that not getting enough fluids will raise my glucose. I'm TRYING to be better about that!

I have that same problem and I try to keep a pot of hot water available for hot herbal tea throughout the day. Or I have a cup of water always with me. It is harder to drink enough in the winter.

Really, I never heard that cold weather raises glucose levels. All the more reason for everyone to move to Southern California where it is warm.

I have been keeping my house at 60 degrees just for an experiment and it saves me money. I don't know if the cold raises my blood sugar, I don't think so but does the 60 degrees affect my glucose monitor or the strips? Am I getting a accurate reading?

Good thought about the best temperature for the glucose monitor and strips. There should be information on the package inserts, or you can check the manufacturer's website for the recommended temperature. ~Lynn @Glucerna

I keep my house between 65 and 68 but I do spend time outdoors a lot. It had not occurred to me that the cold could effect the monitor or strips. Something to consider. I guess my A1c next month will be the true test.

I haven't heard this but I have noticed that I have not made any changes and my glucose levels will not decrease as much as I would like.

I don't have that problem nor have any of my other diabetic friends have said this happens to them. It could be something else. I wouldn't wait a month to discuss this with the doctor, I would call the doctor. My doctor told me that if I notice changes that last more than 72 hours to call him immediately and never wait for my next appointment to see him.

There is no need to call my doctor now. My readings are still well within the desired range for me. Thank you for sharing your experience.
