How much do you know about diabetes? 

Did you know that people of black African, African-Caribbean or south Asian heritage are more likely to develop type 2 diabetes? Dr Joan St John, a GP who specialises in the condition, says many people lack an understanding of diabetes, even some NHS colleagues. In her blog, Millions of people have diabetes but how much do you know about it?, Joan talks about the ways it affects people and gives some helpful tips on staying well if you have diabetes. She also explains how important it is to be able to spot the signs early and encourages everyone to talk openly about diabetes with friends and family.
