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.
Symptoms of sleep apnoea mainly happen while you sleep.
They include:
During the day, you may also:
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.
You have any of the main symptoms of sleep apnoea, such as:
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.
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).

Sleep apnoea can sometimes be treated by making lifestyle changes like losing weight, giving up smoking and reducing how much alcohol you drink.

Tell your doctor if you find it uncomfortable or hard to use.
Other treatments sometimes used for sleep apnoea include:
These treatments may not work as well as a CPAP machine.
If you've been diagnosed with sleep apnoea, there are some things you can do to help.
These may be all you need to do if your sleep apnoea is mild.
try to lose weight if you're overweight
exercise regularly – being active can improve your symptoms and help you keep to a healthy weight
have good sleep habits like making sure your bedroom is dark and quiet, and going to bed and waking up at the same time each day
sleep on your side – try taping a tennis ball to the back of your sleepwear, or buy a special pillow or bed wedge to help keep you on your side
do not smoke
do not drink too much alcohol – especially shortly before going to sleep
do not take sleeping pills unless recommended by a doctor – they can make sleep apnoea worse
Without treatment, sleep apnoea can lead to other problems including:
Sleep apnoea can also be difficult for your partner and put a strain on your relationship with them.
