Well done on your reduced HbA1c
@Dorset Dumpling
Glad to hear the treatment for your bowel cancer has been going well.
Current definitions of remission seem to vary slightly, but the most common one says that remission is 2 HbA1c checks below 48mmol/mol with no diabetes medication being used.
Congratulations on your terrific HbA1c! It shows your diabetes is being very well managed (which is not easy when you are dealing with another illness), and should vastly reduce the risks of any long term diabetes complications. Remission or not - keep going!
