Sleep apnea is a sleep disorder characterized by repeated interruptions in breathing during sleep. These interruptions, called apneas, occur when the airway becomes blocked or when the brain fails to signal the muscles to breathe. Sleep apnea can lead to poor sleep quality, daytime fatigue, and more severe health complications if left untreated.

Types of Sleep Apnea

1. Obstructive Sleep Apnea (OSA):

   • The most common type.
   • Caused by the relaxation of throat muscles, leading to airway obstruction.

2. Central Sleep Apnea (CSA):

   • Less common.
   • Occurs when the brain fails to send proper signals to the muscles that control breathing.

3. Complex or Mixed Sleep Apnea:

   • A combination of obstructive and central sleep apnea.
