Medical Weight Loss With Semaglutide

Have you noticed how maintaining your fitness level and losing weight becomes increasingly challenging as you age, even with consistent effort? You’re not alone!

The MedFit Program Weight Loss Injections

At Derma Skin Medical Spa, we offer a groundbreaking approach to weight loss with our MedFit Semaglutide Weight Loss Program, available in Burlington and Guelph, Ontario. Our program is designed to provide personalized care in your weight loss journey. Upon your initial consultation, our dedicated providers will delve into understanding your goals, lifestyle, and unique needs to craft a treatment plan just for you. The MedFit Program consists of weekly Semaglutide or Tirzepatide injections closely monitored by one of our experienced medical providers.  See if you are eligible below!

Why Semaglutide For Weight Loss?

When we eat, our bodies have a natural “set point” at which our stomach will tell us that we are full. Semaglutide and Tirzepatide, cutting-edge medications proven to aid in weight loss, are at the core of our program. Semaglutide in Guelph or Burlington will help your body find a new “set point” by making you feel full earlier, leading you to naturally eat less at each sitting, resulting in weight loss that typically ranges from 1-2 pounds per week. Under the guidance of our highly trained physician assistants, your weekly Semaglutide or Tirzepatide doses are carefully adjusted, ensuring your journey is not only effective but also tailored to your body’s response and tolerability.
