Pulmonary Disease

Obesity can have an impact on overall lung function. It increases the work of breathing through a decrease in chest wall compliance as well as a reduction in respiratory muscle strength. Obesity increases pressure on the diaphragm, reducing residual lung volume (reduced FEVj, FVC, TLC, and FRC). The result can be a mild restrictive pattern, although typically only in the severely obese population (Poulain et al., 2006). Asthma is exacerbated with increased weight, and obesity-hypoventilation syndrome (hypercapnic respiratory failure and cor pulmonale) is associated with marked degrees of obesity.
