OSA

Meaning

OSA is the clinical acronym for Obstructive Sleep Apnea, a common sleep disorder characterized by recurrent episodes of partial or complete upper airway collapse during sleep, leading to intermittent hypoxemia and significant sleep fragmentation. This chronic condition is profoundly significant in hormonal health because it disrupts the nocturnal release of key anabolic hormones like growth hormone and negatively impacts systemic glucose metabolism. Diagnosis is typically made via comprehensive polysomnography.
