If you search for diabetes management standards for over 60, you will find big changes. Having a low blood glucose target means you hamper the immunity system!!

Of Canadian Diabetes Association Clinical Practice Guidelines Expert Committee reported:
Diabetes in the elderly is metabolically distinct from diabetes in younger people and the approach to therapy should be different.
And RECOMMENDED: A new recommendation for glycemic targets among the frail elderly of glycated hemoglobin (A1C) ≤8.5%, and fasting and pre prandial plasma glucose of 5.0 to 12.0 mmol/L has been added.
(Mind you elderly is 60 and over)
You will find that instead of A1C of < 5.6%, 8% is now the target of medical practitioners in UK and many other countries.
