Lifestyle Interventions and Otolaryngologic Care for Adults with Obesity or Overweight.

Obesity is associated with numerous otolaryngologic conditions, including obstructive sleep apnea, chronic rhinosinusitis, otitis media, and laryngopharyngeal reflux disease, through mechanisms involving chronic inflammation, immune dysregulation, mechanical airway compromise, and metabolic dysregulation. This review examines the evidence linking obesity to otolaryngologic disorders and explores lifestyle interventions relevant to otolaryngologic care. While the strongest evidence supports weight loss for obstructive sleep apnea, benefits extend to other conditions. Practical strategies for integrating lifestyle medicine screening, counseling, and referral pathways into otolaryngology practice are discussed.
