Scientists hail ‘smart’ insulin that responds to changing blood sugar levels in real time

Exclusive: People with type 1 diabetes may in future only need to give themselves insulin once a week, say experts

Scientists have developed a holy grail" insulin that responds to changing blood sugar levels in real-time and could revolutionise treatment for millions of people with type 1 diabetes worldwide.

Patients currently have to give themselves synthetic insulin up to 10 times a day in order to survive. Constant fluctuation between high and low blood sugar levels can result in short- and long-term physical health issues, and the struggle to keep levels stable can also affect their mental health.
