Sleep apnoea is when your breathing stops and starts while you sleep. The most common type is called obstructive sleep apnoea (OSA). Sleep apnoea needs to be treated because it can lead to more serious problems.
Check if you have sleep apnoea
Symptoms of sleep apnoea mainly happen while you sleep.
- breathing stopping and starting
- making gasping, snorting or choking noises
- waking up a lot
- loud snoring
During the day, you may also:
- feel very tired
- find it hard to concentrate
- have mood swings
- have a headache when you wake up
It can be hard to tell if you have sleep apnoea. It may help to ask someone to stay with you while you sleep so they can check for the symptoms.
See a GP if:
You have any of the main symptoms of sleep apnoea, such as:
- your breathing stops and starts while you sleep
- you make gasping, snorting or choking noises while you sleep
- you always feel very tired during the day
If someone else has seen you have the symptoms, it can help to bring them with you to the GP.
Sleep apnoea can be serious if it's not diagnosed and treated.
Getting tested for sleep apnoea
If a GP thinks you might have sleep apnoea, they may refer you to a specialist sleep clinic for tests.
At the clinic, you may be given devices that check things like your breathing and heartbeat while you sleep.
You'll be asked to wear these overnight so doctors can check for signs of sleep apnoea.
You can usually do this at home, but sometimes you may need to stay in the clinic overnight.
The test can show if you have sleep apnoea and how severe it is. This is based on how often your breathing stops while you sleep (AHI score).
Treatments for sleep apnoea
Sleep apnoea can sometimes be treated by making lifestyle changes like losing weight, giving up smoking and reducing how much alcohol you drink.
But many people need to use a device called a CPAP machine. You'll be given this for free on the NHS if you need it.
A CPAP machine gently pumps air into a mask you wear over your mouth or nose while you sleep.
It can help:
- improve your breathing while you sleep by stopping your airways getting too narrow
- improve the quality of your sleep and help you feel less tired
- reduce the risk of problems linked to sleep apnoea, such as high blood pressure
Using a CPAP machine may feel strange or awkward at first, but try to keep using it. It works best if you use it every night.
Tell your doctor if you find it uncomfortable or hard to use.
Other treatments sometimes used for sleep apnoea include:
- a gum shield-like device that holds your airways open while you sleep (mandibular advancement device)
- surgery to help your breathing, such as removing large tonsils
These treatments may not work as well as a CPAP machine.
