Summary

Obesity and COPD are increasingly common and often coexist, worsening health outcomes such as reduced lung function, exercise capacity, and increased systemic inflammation. While COPD was historically associated with underweight, obesity is now more prevalent among these patients and poses new challenges. Despite some evidence that weight loss may improve lung function, comprehensive interventions have not been fully studied. The TRIO-COPD study aims to evaluate a 20-week program combining energy restriction, adequate protein intake, and structured exercise in COPD patients with obesity. The study will assess: Primary outcome: -Exercise capacity (6-minute walking test). Secondary outcomes: -Lung function (spirometry and lung volumes), -symptoms ( assessed via questionnaires), body composition (fat mass, fat-free mass, waist circumference), and inflammatory markers (e.g., IL-6, CRP, CC16). A subgroup will also undergo sputum analysis. The study addresses a critical gap, aiming to determine whether structured weight reduction can improve COPD symptoms, reduce inflammation, and limit muscle loss-advancing understanding of obesity's impact on COPD and providing evidence for potential treatment guidelines.
