A couple have developed a new way of helping their son cope with diabetes.
Before the invention George's family had difficulty remembering his jabs
George Barker, from Newholme near Lincoln, needs four insulin injections each day.
His parents have invented a computer programme which they call Diabeasy which can predict when he will need a sugar boost.
All his meals and medical details are typed in and the programme works out how his body is likely to react.
George's Mother, Ellen Barker described how it works: "We can see from the average results that when he plays tennis his blood sugars are much more controlled.
"But, there is also a good chance he'll get a 'hypo', where he gets very low blood sugars in the afternoon.
"We can also be much more aware of what is likely to happen and take steps to avoid that."
George was diagnosed with diabetes two years ago and the computer program has helped him and his family adapt to life with the condition.
George said: "If you're playing a game your blood sugar goes lower and you can't continue playing the game."
The Barkers now plan to sell the software to other diabetics.
