Wegovy Weight Loss Injection
Wegovy® Weight Loss Injection NZ
Wegovy® is a weekly weight loss injection designed for adults living with obesity or weight-related health conditions. It contains semaglutide, a medication that mimics the natural hormone GLP-1 to help reduce appetite, promote a sense of fullness, and support weight loss when used alongside a balanced diet and regular exercise.
Clinical studies have shown that Wegovy® can help individuals lose up to 15% of their body weight. As one of the most in-demand treatments for those who have struggled with conventional weight loss approaches, weight loss injections are gaining popularity worldwide. Pre-booking is available in New Zealand.
What is Wegovy®?
Wegovy® is a prescription weight loss medication containing the active ingredient semaglutide. It's a GLP-1 receptor agonist that mimics a natural hormone released from the intestine after meals, helping to control appetite and reduce food cravings.
How Does Wegovy® Work?
Wegovy® works by acting on receptors in the brain that control appetite, causing you to:
Feel fuller after eating
Experience less hunger between meals
Have reduced food cravings
Naturally eat less food, leading to weight loss
Are these available as weight loss pills?
At the moment, GLP-1 medications are only available as weight loss injections, but not as weight loss pills.
