Charity Diabetes UK has warned that 7 million people in the UK are pre-diabetic, with the likelihood that they have high blood sugar, high blood pressure, are overweight and have a family member with type-2 diabetes.

The treatment for pre-diabetes is some simple lifestyle changes involving weight loss, a healthier diet and increased activity levels. For those, however, who go on to join the 2.6 million with full blown diabetes there is the risk of heart disease, stroke, kidney failure, blindness and a need for amputation.
