GLP-1 medications like Wegovy and Mounjaro are powerful tools to support your weight loss journey — but like all medicines, they can come with side effects.
At Well by Vertis, we want you to feel informed and supported at every step. Below you’ll find an overview of common side effects, tips for managing them, and guidance on when to reach out for help.

What’s normal?
Most side effects are mild and temporary, especially in the first few weeks as your body adjusts. You might experience:
- Nausea or queasiness
- Constipation or diarrhoea
- Stomach pain or bloating
- Headaches
- Tiredness or low energy
- Mild dizziness
These are typically short-lived and can often be eased with simple changes to your routine (see below).

- Intense stomach pain
