That sounds very strange for type 2 diabetes-to have spikes like that, especially if she is eating right, not overweight, etc. I hope she stays in control and does not have any side effects-I know you are being supportive and will help in any way you can...
It is entirely inexplicable. She has a CGM monitor and eats zero carbs for breakfast. 2 eggs over easy, two pieces of chicken bacon and a half avocado. That is zero carbs. Without Jardiance her glucose will jump 100 points. It defies explanation. If we were rich we’d go to the mayo Clinic but we do what we have to do. Medicine is to treat 90% of the people 90% of the time. If you fall out of that graph, shame on you.
