There are three kinds of sleep apnea: obstructive, central, and mixed. Obstructive sleep apnea is the most common variety, caused by a blockage that occurs when soft tissue around the throat collapses and closes off the airway. Central apnea, which is responsible for less than five percent of all sleep apnea, occurs when the brain does not properly signal the muscles that control breath during sleep, causing breathing to stop and start throughout the night. Mixed sleep apnea is a combination of obstructive and central apnea.

Overweight men over the age of 40 are the most likely to be diagnosed with sleep apnea. Overweight individuals sometimes store extra fat in the neck area, restricting the width of the airway and increasing the chance of becoming constricted during rest. In addition to lifestyle adjustments, including weight loss if necessary, sleep apnea sufferers may benefit from surgery and treatment aids like supplemental oxygen and mouthpieces.

Based in Cincinnati, Ohio,  Dr James Murtagh is Medical Director of Eastgate laboratory, operated by SleepCare Diagnostics.
