Interest in diabetes medicines for overweight has grown because some of these medicines clearly affect appetite and body weight. But the label "diabetes medicine" hides major differences between drug classes and approved uses.
Which diabetes medicines affect weight?
GLP-1 receptor agonists and dual agonists have the clearest effect on appetite and weight, while other diabetes medicines can be weight neutral or only modestly weight reducing.
How GLP-1 differs from SGLT-2 and metformin
These drug classes work through different biological pathways, so their effect on appetite, glucose control and body weight is not the same.
Why indication and dose matter
A medicine may have evidence in diabetes at one dose and a different evidence base or approval status when obesity is the main reason for treatment.
Who may be considered for treatment?
Prescription choice depends on the full clinical picture, including diabetes status, BMI, comorbidity, contraindications and treatment goals.
