Abstract
Obstructive sleep apnea (OSAS) is a very common disease characterized by repeated episodes of complete or partial obstruction of the upper airway during sleep and may lead to many cardiac and neurological complications. Individuals with obstructive sleep apnea are generally obese and present with the history of snoring and daytime drowsiness. Obesity and narrow pharyngeal airway are the most important risk factors along with the male gender. Polysomnography is considered as the gold standard for the diagnosis of OSA, which is carried out in Sleep Clinic. First line of treatment of OSA includes weight loss. Severe cases of OSA should be advised to use continuous positive airway pressure appliance (CPAP) during sleep. Various surgical procedures can also be used as the treatment options.
