What is obstructive sleep apnea (OSA)?

ANSWER

OSA is more common among people who are overweight, but anyone can get it. The tissue in the back of your throat relaxes and blocks your airway while you sleep. You stop breathing, so your brain signals your throat muscles to contract, which opens up your airway again. This can happen dozens or even hundreds of times a night.
