How is sleep apnea diagnosed?

Diagnosing sleep apnea and available tests

What exactly is sleep apnea?


Sleep apnea is a condition that causes you to stop breathing during your sleep. Its most common form, obstructive sleep apnea (OSA), is estimated to affect 35% of men and 20% of women aged between 30 and 70, yet 80% are undiagnosed.1,2

If left untreated, sleep apnea can lead to snoring, fatigue and daytime sleepiness. It can also have serious long-term effects on your health and well-being. 3,4

How to diagnose sleep apnea?


Sleep apnea can be diagnosed through a number of different sleep tests.

There are four types or levels of sleep apnea testing, including ‘home sleep tests’ that you can take in bed at home, and conversely, there are ‘sleep lab tests’ that require you to stay overnight in a hospital or sleep lab.
