I have had my CGM for 2 weeks now. My first 10 days were amazing. My numbers showed very good control 80s-150s post prandial. I spot checked with my glucometer to verify numbers since a CGM is new to me. My trend never showed any big spikes after a meal. My baseline stayed around 100s. I changed my CGM last Thursday and my numbers started going much higher. I verified with glucometer and they were accurate. I am seeing regular spikes to 180s-200s with my baseline around 130s. About an hour after I eat I see a mountain on my reader trend. It goes up sharply which was not happening previously. The only other thing different is that I had to change my Treciba pen last Wednesday and my Fiasp pen last Thursday. I went up on my Treciba from 52 units to 60 units. It does not seem to make a difference.
Is it possible that there is something wrong with the insulin pen? I have not changed my eating habits, at all. This just seems weird to me. The Treciba pen is from a new box I picked up from pharmacy.
I am putting this out there because this community knows more than most medical people, You folks live it and I am still learning. Ideas? Suggestions?
