Obesity causes important changes in lung function, and some tests, such as spirometry and volumetric capnography (VCap), may help diagnose these complications. Objective was to describe the influence of weight loss on improvement of lung function. An individual with morbid obesity grade III, who participated in the multidisciplinary weight loss approach of the HC of Unicamp and was submitted to initial and final evaluations of anthropometric measures and pulmonary function, was evaluated. Spirometry, volumetric capnography and risk of developing sleep apnea were performed by the Berlin questionnaire. After weight loss of 90 kg, BMI of 28 kg / m², improvement in spirometric values was observed in the first and second moments in the variables of forced vital capacity (FVC), final expiratory volume in the first second (FEV1), final expiratory flow. In volumetric capnography, there was an increase in alveolar minute volume [MValv (L)], minute volume of airway space [MVd aw (L)], peak expiratory flow and [PEF (L / min)]. risk for the development of obstructive sleep apnea has evolved from high to low risk. Conclusion: The multidisciplinary approach to weight loss is an important tool to assist the individual in the process of losing weight in an educational and healthy way. Weight loss occurs as a result of effort and learning and leads to health benefits such as improved lung function and mechanics and quality of sleep.
