What counts as weight loss medication?
Weight loss medication is any licensed medicine prescribed to support weight management in people living with obesity, or with overweight plus a weight-related health condition. In the UK these fall into two broad groups.
GLP-1 receptor agonists
These mimic a gut hormone your body already produces after eating. They slow how quickly the stomach empties and act on appetite centres in the brain, so you feel full sooner and stay full for longer. Mounjaro, Wegovy, Saxenda, Nevolat, the Wegovy Pill and Foundayo all work this way.
Lipase inhibitors
Orlistat and Xenical work in the gut rather than on appetite. They block the enzyme that breaks down dietary fat, so around a third of the fat in your meal passes through undigested instead of being absorbed.
Which group is right for me?
GLP-1 treatments generally produce greater average weight loss, but they are more expensive and require either a weekly or daily dose. Lipase inhibitors cost considerably less and avoid injections entirely, but the average weight loss is more modest and they require a consistently low-fat diet to be tolerable. Your prescriber will talk this through with you during your consultation.
