Findings reveal improved airway resistance post bariatric surgery, suggesting benefits for obese individuals' breathing.
Severe obesity adversely affects respiratory mechanics by increasing airway resistance and reducing lung compliance, contributing to dyspnea and impaired quality of life [1]. Shortness of breath is highly prevalent among candidates for bariatric surgery [2]. Recent evidence indicates that dyspnea affects the majority of bariatric surgery candidates and improves substantially following weight loss [5]. However, objective assessments of respiratory system impedance after bariatric surgery remain limited.
