Health Check: Insulin pump

Help

Professor John Pickup of Guy's Hospital in London has been pioneering the use of a new insulin pump for diabetics.

The pump mimics the way someone without diabetes receives insulin from their pancreas: a slow background supply of insulin, with boosts at mealtimes.

Diabetic patient Andy Skinnard switched to the pump recently, having injected insulin for 20 years. He is one of just 2% of insulin-dependent diabetics using the pump in the UK and tells Health Check's Claudia Hammond how it has improved his life.
