The effect of massive weight loss on pulmonary function of morbid obese patients

Abstract

These results point out that the severe morbid obesity (BMI>or=60 kg/m(2)) may lead to pulmonary function impairment and presents more prominent pulmonary function gain after massive weight reduction. The possible clinical implications of these results are that PFT abnormalities in subjects with BMI<60 kg/m(2) should probably be interpreted as consequence of intrinsic respiratory disease and that severe morbid obese patients may be encouraged to lose weight to improve their pulmonary function, especially those with concomitant pulmonary disorders.

Improvement of restrictive and obstructive pulmonary mechanics following laparoscopic bariatric surgery

“…Improvement of pulmonary function after bariatric surgery has been observed in several small studies. Santana and colleagues examined changes in pulmonary function test in 39 patients who underwent weight-loss surgery [7]. At a mean 12 months postoperatively, they found a significant increase in both FVC and FEV 1 compared with baseline and improvement of pulmonary function was greater in the super-super obese (BMI [ 60 kg/m 2 ) compared with morbidly obese patients (BMI \ 60 kg/m 2 ).…”

Gain in lung function after weight reduction in severely obese children

“…A second open follow-up study in adults who underwent surgery for gastric volume reduction also showed gains in FVC and FEV 1 12. The group with the highest BMI showed the greatest gain, despite exhibiting the same degree of relative weight loss.…”

Effects of Obesity on Pulmonary Function in Adult Women

“…연구 방법 Ⅲ. 연구 결과 소하였으며 (Bottai, et al, 2002;Steele, et al, 2009), 고도 비만에서 체중감량 후 폐기능이 호전되었 다고 한다 (Santana, et al 2006). BMI and WC showed negative association with pulmonary function in obese adult women.…”
