During this webinar, expert faculty will discuss the strong, bidirectional link between obesity and obstructive sleep apnea (OSA) among aging and older adults. They examine how excess weight contributes to airway collapse and decreased lung volume and how untreated OSA-induced fatigue and hormonal changes may lead to further weight gain. The faculty will highlight heightened risks for comorbidities such as hypertension, cardiovascular disease, type 2 diabetes, and cognitive decline when both conditions are present, and they will review interprofessional treatment approaches aimed at improving health and quality of life for older and aging adults with obesity and OSA.
