Welcome to the XXVIII IFSO World Congress 2025 in Santiago, Chile – “Combined Therapies: The Dawn of a New Era”.

This is an exciting time for our field because combined treatment strategies will herald a new dawn for the treatment of obesity. The evolution of surgical techniques, new medications and endoscopic therapies need our critical evaluation. This congress will bring together world leaders from many disciplines focused on treating obesity. Sessions will be provocative and exciting with the goal of delivering better treatment for the pandemic of obesity.

We invite you to actively participate in scientific sessions, workshops, pre-congress courses and networking opportunities. Let us seize this opportunity to learn from each other, challenge conventional wisdom, and collectively explore novel solutions that can make a meaningful impact for our patients living with obesity.

An official personalized letter of invitation will be provided to registered participants as part of the registration process. You will be able to generate an invitation letter at the end of the registration process, and you will also receive a confirmation email with a link to the invitation letter.

This invitation is prepared solely for the purpose of visa applications and is not a commitment on the part of the organizers to provide any financial support or confirmation of inclusion in the scientific program.
