Diabetes patients test effectiveness of insulin pumps

Diabetes patients have joined a trial to assess the effectiveness of pumps which deliver insulin directly into the body.

Addenbrooke's Hospital in Cambridge has recruited 1,000 diabetics to assess whether the pumps are more effective than daily multiple injections.

Nearly three million people in the UK have been diagnosed with diabetes and it is estimated another 850,000 people have the condition but have not been diagnosed.
