Abstract:
Obesity alters upper aerodigestive physiology through changes in respiratory mechanics, upper airway stability, reflux burden, esophageal clearance, gastric emptying, and systemic inflammation. These changes may contribute to a myriad of voice, swallowing, and airway pathologies. This article examines the relationship between obesity and upper aerodigestive tract disorders, focusing on voice, swallowing, reflux, airway mechanics, perioperative/postoperative risks, and management relevant to laryngologists and comprehensive otolaryngologists alike.
