Exploring Genetic Factors in Weight Loss Drug Efficacy

Recent years have seen the advent of weight loss drugs, including Ozempic and Wegovy. They work by suppressing users' appetites, leading to weight loss.    
 
They've been described as wonder drugs but now, new figures from the Medicines and Healthcare products Regulatory Agency (MHRA) show they may be associated with inflammation of the pancreas, which could lead to death.  
 
Niall Paterson speaks to Sky's science correspondent, Thomas Moore, about these new findings and how cautious they should make us. We also hear from Lorna, a mother who got acute pancreatitis while she was on a weight loss drug - she believes the drugs are not worth the risks.
