Sleep apnea is a sleep disorder characterized by interruptions in breathing during sleep, which can lead to various symptoms such as loud snoring, choking or gasping for air, daytime sleepiness, morning headaches, and mood swings. Treatment options for sleep apnea may include lifestyle changes, continuous positive airway pressure (CPAP) therapy, oral appliances, positional therapy, or in more severe cases, surgery. It is important to consult a healthcare professional for proper diagnosis and treatment recommendations tailored to individual needs.
