Obesity and sleep: a growing concern.

PURPOSE OF REVIEW: The 'obesity epidemic' is a growing concern globally, and obesity trends are projected to continue increasing in both prevalence and overall mean BMI. Cardiovascular and metabolic comorbidities have historically been well described; however, obesity-related respiratory disease is now increasingly prevalent, in particular, sleep disordered breathing. The surge in clinically significant obstructive sleep apnoea and obesity hypoventilation syndrome is associated with increased cardiopulmonary morbidity, quality-of-life impairment, and a potential rise in the frequency of road traffic accidents. RECENT
FINDINGS: We discuss recent trends in obesity and obesity-related sleep disordered breathing. We also discuss recently published international guidelines regarding the diagnosis and management of sleep disordered breathing, and in particular, the role of weight management interventions, such as bariatric surgery, in this area. We discuss possible approaches to meet the growing demand for sleep assessment and management in the future.
SUMMARY: Obesity-related respiratory disease reflects an increasing proportion of patients in both inpatient and outpatient settings. It is important to recognize the impact of obesity on pulmonary physiology in order to appropriately care for this population, as well as plan for the future.
