Abstract excerpt

Bariatric surgery (BS) induces weight loss, but long-term success involves complex host-microbiome interactions. We evaluated the longitudinal impact of BS, microbiome resilience, and Mediterranean Diet (MedDiet) adherence up to 24 months. This prospective observational study included 85 patients with severe obesity undergoing BS and 21 normal-weight healthy controls (HC). MedDiet adherence (PREDIMED) was...
