Weight Loss Injections

Adam Walton discusses the science behind popular weight loss injectibles, originally developed to support people with type 2 diabetes.

We hear from the Director of University College Dublin's Diabetes Complications Research Centre, Professor Catherine Godson. She explains what these injections are made of, how quickly they are developing, and what benefits they can have.

Nutritionist, Dr Chris Cashin from the University of Wales Trinity Saint David, responds to some of the risks associated with taking these medications.

Plus, we chat to BBC Wales Health Correspondent, Jenny Rees, who has been researching these injectables for over a year.
