Whenever a patient is diagnosed for the first time for diabetes
type 2,50% of beta cells are dead.
These beta cells are present in pancreas
and are responsible for production of insulin.
After a span of 10 years after the diagnosis of diabetes,these beta cells must have been dead almost completely and hence no oral antidiabetics may help except few like ACARBOSE
Since ,in addition,you have compromised kidney functions,ideal would be to get injectable insulin for control of your diabetes.
Make sure to get your sugar levels in tight control,to avoid complications later on.
Along with sugar,take care of your blood pressure and lipid profile
also in check.
I hope it helps.
