Sleep apnea is a serious sleep disorder in which breathing repeatedly stops and starts during the night.

The main types of sleep apnea are:

• Obstructive sleep apnea – the more common form that occurs when throat muscles relax
• Central sleep apnea – which occurs when your brain doesn’t send proper signals to the muscles that control breathing
• Complex sleep apnea syndrome – also known as treatment-emergent central sleep apnea, which occurs when someone has both obstructive sleep apnea and central sleep apnea
