Can addressing obesity improve sleep apnea?
Learn about the connection between this common comorbidity for your patients with obesity and how it can affect their health
It is estimated that nearly half of all people with obesity also have obstructive sleep apnea1
Obesity is associated with fat deposition in the upper respiratory tract, which can lead to mechanical, hormonal, and inflammatory effects, impacting the severity of OSA.2,3
Mechanical load increase
respiratory stress
Proinflammatory cytokines
reduced CNS activity and upper airway control
Oxidative stress increase
lowered upper airway function
A 10% weight gain in people with an average BMI of 29 kg/m2 increases the likelihood of developing moderate to severe sleep apnea by 6 times, and incidence increases with BMI.4*
*This study was a population-based, prospective cohort study of 690 patients that measured the independent longitudinal association between weight change and change in sleep-disordered breathing severity.
†The intent of this study was to determine the prevalence of OSA in 290 patients with obesity presenting for weight-loss surgery.

BRING OBESITY TO THE FOREFRONT
WITH YOUR PATIENTS WITH OSA
AACE guidelines recommend a weight-loss goal of 7% to 11% or more for patients with obesity and obstructive sleep apnea.6
Obesity is caused by a range of factors
Patients may be waiting for HCPs to take that important first step and discuss weight management
