When you say I have answered my own question what do you mean. Does that mean I am T2 if it goes up when I forget the insulin. I am only an expert on me and anything that doesn't concern me has passed my by in the last 17 years. I can only learn so much. 🙂Your age does not preclude you from being Type 1 or LADA, there are many who have been diagnosed even in their 80 ies.
You may have answered your own question by saying if you don't have your insulin even the small dose your blood glucose goes up.
