Sleep apnea is of three types:
Obstructive Sleep Apnea
Central Sleep Apnea
Complex Sleep Apnea Syndrome
Sleep apnea is diagnosed with the help of Nocturnal polysomnography, a device that monitors the activity of the lungs, brain, and heart, breathing patterns, and oxygen levels in the blood while sleeping.
Your doctor would prescribe the treatment based on the reading. Lifestyle changes, medication, and therapies would help. Surgery is recommended in rare cases to remove tissue, tonsils, and adenoids, place implants, or reposition jaws to alleviate the problem.
