You're right walshdon! The Halle Berry saga was very much a big hype, but type1 or type2 matters not....neither are curable. In fact NO diabetes is curable!
Yes, I agree that they are not curable. But before throwing out the baby with the bath water; under proper fixing if certain medical issues ( Insulin, metformin) and other new hormones, with a rational diet reducing carbs and sufficient exercise to achieve lower glucose levels in blood stream ( under 7 a1c); it is possible to stop/reduce the damage and rot. That is not a cure/reversing diabetes but it is managing the issue better.
I hope it might help
Latest data and experience of myself and some thers; that if one gets stress off pancreas - fix diet, exercise and somei nsulin, Pancreas can and does recover some of the islets. Thinking now is suggesting that under severe stress, pancreas islets revert to some pre-form not responding and producing insulin.
See work done at University of Newcastle upon Tyne - re: Dr/Professor Roy Taylor at their MRI spectromety work watching type 2 diabetics having their insulin production recover on tight diets. Those on bariatric surgery also show similar results.
