Introduction to GLP-1 medications
GLP-1 (glucagon-like peptide-1) medications are a class of drugs primarily used in the management of type 2 diabetes and weight loss. They mimic the action of the natural GLP-1 hormone, which helps regulate blood sugar and appetite.
The main types of GLP-1 medications
Understanding the different options helps you and your doctor choose the most suitable treatment. The common GLP-1 medications used today include:
- Exenatide (Byetta, Bydureon) — used for type 2 diabetes, helping improve blood sugar control.
- Liraglutide (Victoza, Saxenda) — available for diabetes management and as a treatment for obesity.
- Dulaglutide (Trulicity) — a once-weekly injection, improving convenience.
- Semaglutide (Ozempic, Rybelsus, Wegovy) — notable for its effectiveness in weight loss and diabetes control, in both oral and injectable forms.
- Tirzepatide (Mounjaro) — a dual GLP-1/GIP medication with some of the strongest weight-loss results to date.
See how the claim works →How do GLP-1 medications work?
GLP-1 medications work by enhancing insulin secretion, reducing glucagon secretion, and slowing gastric emptying. This not only helps control blood sugar levels but also reduces appetite and calorie intake, which aids weight loss.
The benefits
Beyond their role in managing blood glucose, GLP-1 medications offer other benefits, including weight loss, improved cholesterol levels and lower blood pressure.
Are you a candidate for GLP-1 medication?
GLP-1 medications are highly effective for many people but are not right for everyone. Your medical history, current health and specific goals all matter — which is why a doctor should assess your suitability before prescribing. Our Irish-registered doctors do exactly that.
