A new era for type 1 diabetes treatment

Insulin has been used to treat type 1 diabetes for more than a century but now there is a new treatment being rolled out on the NHS that can delay the onset of the disease for years.

Parth Narendran, a Professor of Diabetes Medicine at the University of Birmingham, and Consultant Paediatric Endocrinologist Dr Renuka Dias at Birmingham Women's and Children's Hospital, reveal how these changes are transforming treatment.
