Types of Sleep Apnea

There are two types of sleep apnea:

• Obstructive sleep apnea (OSA): The more common of the two forms of apnea, it is caused by a blockage of the airway, usually when the soft tissue in the back of the throat collapses during sleep.
• Central sleep apnea: Unlike OSA, the airway is not blocked but the brain fails to signal the muscles to breathe due to instability in the respiratory control center.

Those with sleep apnea symptoms should consult their physician immediately.
