It's cause of concern that your insulin
is not acting to neutralize the sugar
while you are taking good medicines prescribed by your experience doctor. This is non response of drugs. It's not fault in treatment by your doctor. I would suggest the support of ayurveda
medicine as support to your current medicine. Both won't counteract with each other. Observing the response of this integrative approach, further directions would be decided.
If you agree, I would mention the first phase of safe, side effect less, easy to take and economic medicines which will prevent complications also.
