Congrats on ur a1c!!
I do agree with health on this. While a a1c of 6.7 is good, she mustve worked very hard to achieve it, our goal is to try to have control as close to normal as possible. An a1c of under 5 is definitely possible, it does require a lot of diligent work but is absolutely achievable. I know of a couple of types 1 who have their number in that range.
Cf, ur doc recommends a higher a1c since she’s pediatric, when dealing with kids the endos tend to be a bit more careful with lows.
That being said, i think that some ppl tend to have better a1c than others even with the same control, I wonder if there is more to it.
