Sleep apnea is characterized by an obstruction in the patient's airway.
Sleep apnea is the main cause of sleep-disordered breathing. This condition is characterized by the subject’s inability to breathe properly while they're asleep, due to the collapse of their airways. This obstruction can happen due to several reasons, including a genetic predisposition. Additionally, individuals who are obese or overweight are more prone to suffering from sleep apnea, as the additional pressure on the neck can cause the airway to collapse while patients are asleep. Other risk factors can include an abnormally large tongue or the presence of enlarged adenoids and tonsils.
