yes I agree with that wholeheartedly. Now if the Diabetic peripheral neuropathy (nerve damage would go away everything would be easier).
Ive got a lot of specialists and they all say it is not reversable , once the damage is done its done for good.
Try this... https://www.diabetes.co.uk/forum/threads/retinopathy-reversal.175092/ “The overall degree of retinopathy generally improves with good diabetic control (blood glucose, blood pressure and lipids). The earlier good control is instigated, the more likely this is to happen. It's never too late, though - even if retinopathy is well-established, the risk of progression is reduced by improving diabetic control. http://www.diabeticretinopathy.org.uk/prevention/hba1c_and_retinopathy.htm
