Obstructive sleep apnea is a common sleep disorder characterized by repetitive episodes of complete or partial obstruction of the upper airway during sleep, leading to pauses in breathing and disrupted sleep. This results in poor oxygenation of the body and can have serious consequences on overall health, including increased risk of cardiovascular disease, stroke, and diabetes. Treatment options for obstructive sleep apnea may include lifestyle changes, continuous positive airway pressure (CPAP) therapy, oral appliances, or surgery. Research in this area focuses on improving diagnostic methods, identifying risk factors, understanding the underlying mechanisms of the disorder, and developing more effective treatments to improve the quality of life for individuals with obstructive sleep apnea.
