Sleep-Disordered Breathing

Meaning

Sleep-Disordered Breathing (SDB) is a spectrum of clinical conditions characterized by abnormal respiratory patterns or insufficient ventilation during sleep, ranging from habitual snoring to the more severe Obstructive Sleep Apnea (OSA). This condition results in recurrent episodes of hypoxemia and sleep fragmentation, which places a chronic stress burden on the cardiovascular and endocrine systems. Untreated SDB is a significant contributor to metabolic dysfunction and hormonal imbalance.
