“My wife is a T1 diabetic”
Ozempic is not designed for nor approved for type 1 diabetes. Your wife’s doctor is prescribing it off label.
I would be looking for a second opinion if it were me or my family member.
Her doctor is trying to help her with weight loss from the perpetual balancing of carbs vs insulin. Keeping the total under control while dodging low glucose levels has been a huge challenge. Having her glucose monitor alarm going off in the middle of the night screws up sleep for both of us. That is her problem to manage. I'm trying to dodge sleep apnea and the local clinic that provides the monitors to get an accurate read has a 60 day wait. Getting through a workday with 3 or 4 hours sleep is not much fun.
My personal opinion on Ozempic for a T1DM patient is avoid it. The frantic attempts to fix a glucose low with the delayed dump of stomach contents isn't worth the risk. We have a fast acting glucagon stimulating nasal inhaler as a fallback for her.
