The etiology of OSA involves both structural and nonstructural factors, including genetic factors.

Hypothyroidism is associated with macroglossia and increased soft tissue mass in the pharyngeal region and thus with an increased risk for sleep-disordered breathing. Hypothyroidism is also associated with myopathy that may contribute to upper airway dysfunction. Although it has been linked with the development of OSA, evidence indicates that its prevalence is no higher in patients with OSA than in the general population. Accordingly, patients with OSA should not be routinely screened for hypothyroidism, except possibly elderly women.
