David Childs thought he was fit and healthy - but when the then 48-year old started to feel his eyesight failing, started getting headaches and even fainting, he knew something was wrong: It was type 2 diabetes.
The diagnosis came as a surprise - David is not overweight - but though obesity does increase the risk of developing diabetes, it is not the only factor and 10% of people who do get it don't have a BMI in the overweight or obese categories.
But David, who is from Cleadon, has been taking part in a game-changing medical trial led by Newcastle University' s Prof Roy Taylor. This study has now shown that by changing diet, type 2 diabetes can be reversed and "put into remission". For David, this is now the case, and as he looks to the future he's determined to stay healthy.
