Over the last few months i have started on the insulin pump with great control my A1C last year was 14.7 and last week my A1C was down to 7 with is very good for me. i have had diabetes for almost 8 years now, my A1C has been as high as 17.4 before. So with the recent new change in my blood sugars since being on pump I have experience a lot of stomach issues and a lot of pain in stomach and back. Doctors have run a lot of test ( blood work, ultrasound and CT scan) and nothing is showing up in them, the doctors are puzzled. My diabetes doctor had said to me when people have recent fast changes in BS in a short period of time can have these problems which I am having. I have never heard of this, and I can't find anything on the internet about this. I was just Wondering if anyone has had this problem before? It is getting worse with me. Any comments anyone would have is a great help to me.
