Many people have heard about Wegovy and Mounjaro as options for weight loss, but there is often confusion about how these medications work and what treatment actually involves.
In this video, nurse practitioner Yvonne explains that Wegovy is not a magic solution. Instead, weight loss medication is a tool that can support long-term weight management when combined with personalised medical care, nutrition advice and sustainable lifestyle changes.
How do Wegovy and Mounjaro work?
Wegovy is a once-weekly injection that mimics a naturally occurring hormone in the body called GLP-1.
This hormone plays an important role in regulating appetite. It slows the movement of food through the stomach, helping you feel fuller for longer and reducing feelings of hunger. Many people also notice they spend less time thinking about food throughout the day, making it easier to make healthier choices and control portion sizes.
Mounjaro is also a once-weekly injection, but works on two hormone pathways, GIP and GLP-1. This is why it is often described as a dual agonist. Like Wegovy, it can help regulate appetite, increase feelings of fullness and reduce food intake.
Both medications are now being used as part of medically supervised weight management, although which option is most appropriate will depend on your individual health, circumstances and treatment goals.
While these effects can make weight loss more achievable, medication works best as part of a broader treatment plan rather than as a standalone solution.
What to expect in the first month
Treatment with Wegovy or Mounjaro starts at a low dose, allowing the body time to adjust and helping reduce the likelihood of side effects.
Some people experience nausea, constipation or fatigue during the first few weeks, although not everyone will have these symptoms and they usually settle as treatment continues.
Many people notice their appetite decreases and that smaller meals leave them feeling satisfied. The goal is not perfection but building consistent, sustainable habits that support long-term health.
Why medical supervision is important
As the popularity of weight loss medications has increased, more people are beginning treatment without comprehensive medical support.
Without appropriate guidance, there is a greater risk of side effects or incorrect use. Some people may increase their dose too quickly, miss doses or be unsure how to manage their treatment safely.
Successful weight management is about more than the number on the scales. It is about improving overall health while ensuring treatment is appropriate for your individual circumstances.
Regular monitoring allows treatment to be adjusted when needed and provides support through every stage of the journey.
