Dear Colleagues, Dear IFSO Members,

Welcome to the XXVIII IFSO World Congress 2025 in Santiago, Chile. This narrowest and longest strip of land in the world will offer you the best Southern hemisphere ski resorts and world class surfing on the same day. This magical land of Nobel laureates and dramatic landscapes will host the World Congress in the vibrant city of Santiago.

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.

Santiago, with its rich culture, stunning landscapes, and warm hospitality is waiting for you as the gateway to explore the natural beauties of the number one destination for adventure travel.

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.

Best regards,

Camilo Boza, Congress President
Ricardo Cohen, IFSO President
