What is Wegovy?

Wegovy(semaglutide) is a groundbreaking treatment, specifically licensed for weight management in Ireland.

It’s the first once-weekly GLP-1 medication developed exclusively for people seeking safe, sustainable weight loss — not just blood sugar control.

In clinical trials, patients using Wegovy lost an average of 15% of their body weight, combined with simple lifestyle changes like healthier eating and regular movement.

How Wegovy Works

Scientifically Advanced Mechanism Wegovy works by mimicking the action of the naturally occurring hormone GLP-1 (glucagon-like peptide-1), targeting key pathways in the brain and body that regulate appetite and food intake.

-

Brain Receptor Activation: Binds to GLP-1 receptors in the hypothalamus, the brain's key appetite control center

-

Appetite Reduction: Decreases hunger signals while increasing feelings of fullness and satisfaction

-

Delayed Gastric Emptying: Food remains in your stomach longer, providing extended satiety

-

Reduced Cravings: Diminishes the desire for high-calorie foods by affecting reward pathways

Clinical Results

The STEP 1 clinical trial followed over 1,900 adults using Wegovy alongside lifestyle changes. After 68 weeks, participants achieved significant weight loss and improvements in key health markers, demonstrating Wegovy’sl role in sustainable weight management.

Wegovy is a once-weekly injection that fits easily into your routine. You simply use a pre-filled pen under the skin (abdomen, thigh, or upper arm) — at any time of day, with or without food. To help your body adjust comfortably and minimise side effects, you’ll gradually increase your dose over several weeks.

This slow and steady approach gives you the best chance of success — and lasting weight loss.

Wegovy comes as a pre-filled injection pen and is taken once per week, at any time of day, with or without food.

What is the most important information I should know about Wegovy®?

Wegovy and Mounjaro are both prescription weight loss injections, but they work slightly differently in the body:

Wegovy contains semaglutide, a medication that mimics a natural hormone called GLP-1 (glucagon-like peptide-1). GLP-1 helps regulate appetite and food intake by signaling fullness to your brain and slowing stomach emptying. This leads to reduced hunger and lower calorie intake over time.

Mounjaro contains tirzepatide, a newer medication that mimics two hormones — GLP-1 and GIP (glucose-dependent insulinotropic polypeptide). GIP also plays a role in controlling blood sugar and appetite.

Because it acts on two pathways instead of one, Mounjaro may offer stronger appetite suppression and greater average weight loss compared to GLP-1-only medications like Wegovy.

In clinical studies:

People taking Wegovy lost about 15% of their body weight on average.

People taking Mounjaro achieved up to 20–22% weight loss at the highest doses.

Both treatments require medical supervision and regular check-ins to monitor your progress.
