In 522 patients, average weight loss was approximately 32 pounds at balloon passage and 31 pounds 1 year later, equating to approximately 95% weight maintenance

In 497 patients, average weight loss was 14.3% of total body weight at balloon passage, with 86% of patients maintaining that weight loss 1 year later

Allurion Technologies, Inc. (NYSE: ALUR), a pioneer in metabolically healthy weight loss, today announced new publications on long-term weight loss results with the Allurion Program.

In the first study, 522 patients treated with the Allurion Program across nine international obesity centers reduced their weight, on average, by 14.4kg (32lbs) or 13.9% of total body weight in just four months. One year later, the average weight loss was 13.9kg (31lbs) or 13.2% of total body weight, equating to weight loss maintenance of 95% one year after the Allurion Balloon passes out of the body.¹

In the second study, 497 patients treated with the Allurion Program at a single center between January 2020 and January 2024 reduced their weight, on average, by 14.3% of total body weight in just four months. One year later, 86% of patients maintained their weight loss.²

“Two of the key tenets of metabolically healthy weight loss are losing weight and keeping it off,” said Dr. Shantanu Gaur, Founder and CEO of Allurion. “We are pleased to see an increasing number of publications that demonstrate that the Allurion Program delivers fast weight loss results that can be maintained in the long-term, through an emphasis on behavior change delivered through our AI-powered Virtual Care Suite.”
