Weight-loss injections have rapidly moved from specialist clinics to social media feeds and high-street pharmacies. Known as GLP-1 medications, they were originally developed to support those with type 2 diabetes but are now widely used to support weight loss.
These medicines mimic a hormone called glucagon-like peptide-1, which helps regulate appetite and blood sugar. By slowing digestion and increasing feelings of fullness, they often lead people to eat less and lose weight.
