I have never heard of this type of diagnosis, but anything is possible I suppose. I can see
Type 1.5 maybe. Please read the information on either side of the enclosed T1.5 link. In the T1 information it mentions: "There seems to be little or no link between Type 1 and Type 2 diabetes."
I would want a second opinion of this diagnosis! Just saying.
If you are T1, insulin dependent, are you counting carbs and matching the carb intake with insulin?
