"There is an epidemic of type 2 diabetes worldwide and the incidence of diabetes is rising due to increasing life expectancy and rising obesity in the young . Mortality rates for diabetic kidney disease have not gone down so we have a lot to do said Dr ryan at the recent ADA(American Diabetes Foundation) conference in Boston. We have become very successful at treating complications of diabetes but compliance with diet and medications is still a big issue and obesity is bringing more new diabetics into our clinics. Obesity is the main cause of type two diabetes and we have been unsuccessful in stemming the tide so our health system is going be saturated and we need to address this. There are very good drugs being produced but still no overall cure. A lot more research and education of the public regarding a healthy eating diet needs to be done to stem the tide of diabetes. Once you have diabetes it is irreversible however you reverse the metabolic syndrome which is a pre-diabetic state of abdominal obesity high blood pressure and dyslipidaemia. We must endeavour to prevent diabetes developing by educating our population on healthy eating otherwise we will have an unmanageable epidemic in our hands".
