Interoception and Illness Perception Before and After Bariatric Surgery: Impact on Disordered Eating (Interoceptiv-BAR)
Interoception and Illness Perception Before and After Bariatric Surgery: Impact on Disordered Eating Behaviors
Source: ClinicalTrials.gov · Last updated 3 Sept 2026
Brief summary (registry, in English)
Obesity is associated with alterations in the perception and interpretation of internal bodily signals (interoception), which may influence eating behaviors, emotional regulation, and long-term weight outcomes. Bariatric surgery induces profound physiological and neurohormonal changes that may affect interoceptive awareness and illness perception, potentially impacting the risk of disordered eating behaviors after surgery. This observational study aims to evaluate longitudinal changes in interoceptive awareness and illness perception in adults with severe obesity undergoing bariatric surgery, from the pre-operative phase to long-term follow-up. The study also explores the relationship between these psychological constructs and clinical and behavioral outcomes over time.
