Summary

Postural changes are known to affect normal lung volumes. A reduction in sitting to supine functional residual capacity (FRC) is well-described in non-obese subjects adopting a supine position. However, postural changes in lung volumes in the obese require further exploration. We aimed to longitudinally address the effects of weight loss on postural changes in lung volumes and pulmonary function, in obesity. We tested the hypothesis that supine reduction in FRC would be absent in morbid obesity and recovered upon weight loss.

Conditions

• Obesity

Interventions

Type	Name	Description
OTHER	Postural change in lung volumes: sitting to Supine	Pulmonary function and arterial blood gases were assessed both prior to and after weight loss as part of pre-operative and 12-month follow-up evaluations. Pulmonary function tests were performed both in the sitting and then in the supine position.
