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.

CPAP machine

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

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.

You can find out more about CPAP machines and other sleep apnoea treatments on the British Lung Foundation website.

Things you can do to help with sleep apnoea

If you have 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.

Do

• 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

Don't

• 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

The British Lung Foundation has local support groups and you can get travel advice from the British Snoring and Sleep Apnoea Association.

Sleep apnoea can cause other problems

Without treatment, sleep apnoea can lead to other problems including:

• high blood pressure
• a higher chance of having a stroke
• type 2 diabetes
• heart disease
• depression or changes in your mood
• a higher chance of having a serious accident caused by tiredness, such as a car accident
• difficulty concentrating at work or school

Sleep apnoea can also be difficult for your partner and put a strain on your relationship with them.

Driving and sleep apnoea

You may need to tell the DVLA about your sleep apnoea.

If sleep apnoea has been confirmed, you must not drive until your symptoms are under control.

You can check the rules for driving if you have sleep apnoea on the GOV.UK website.

Causes of sleep apnoea

Sleep apnoea happens if your airways become too narrow while you sleep. This stops you breathing properly.

Sleep apnoea has been linked to:

• obesity
• having a large neck
• getting older – although children and young adults can also get it
• having other family members with sleep apnoea
• smoking and drinking alcohol
• having large tonsils or adenoids
• sleeping on your back
• a condition called chronic obstructive pulmonary disease (COPD).
