Storms in and of themselves only stress me when there is a possibility of tornadic activity.
A few years ago, around 4:00 in the afternoon, I visited my CDE to attach a CGM for a week long CGM tracking study. By noon the next day, I was calling her freaking out because ever since we had attached it I was unable to settle between 60 and 200--sometimes hitting both within the same hour of each other. The CGM was the ONLY difference. I was so frustrated I asked her if there was any possibility I was in a double-blind study I didn't know about and the CGM was controlling my pump without my knowledge. I knew how "conspiracy theorist" that sounded but it was the only thing I could think of.
Her response? "We had a thundersnow storm last night, and barometric pressure affects blood sugar".
First I had ever heard of it, but now that I'm aware of it I definitely have lows when a storm comes through.
