Sorry but a type 2 can never become a type 1 because they are caused by differently.Really according to my edo the only thing the 2 dieases have in common is that they both close high glucose levels and are treated with the same drugs sometimes. You can however be an insulin dependant type 2. I’ve been a type 1 diabtic since I was 9 years old which was close to 40 years ago. It would be wonderful to find something else to help.
