Sleep apnoea living patient overview
Informed by recognized medical guidance
Overview
Sleep apnoea is a condition where your breathing stops and starts while you sleep. It happens because your airway becomes narrow or blocks, often due to relaxed throat muscles. This can wake you up many times at night without you realizing it, leading to poor sleep quality.
Key facts
- It is more common in men and people who are overweight.
- It can cause loud snoring and gasping for air during sleep.
- Untreated sleep apnoea increases risk of high blood pressure, heart disease, and stroke.
Yes, sleep apnoea is quite common. It affects about 1 in 5 adults and many are undiagnosed.
Sleep apnoea can affect anyone, but it is more common in men, people over 40, those who are overweight, and those with a family history. Children can also have it, often due to large tonsils or adenoids.

Causes
Main causes
- Obstructive sleep apnoea – throat muscles relax too much, blocking the airway.
- Central sleep apnoea – the brain doesn't send proper signals to control breathing.
Risk factors
- Overweight
- Large neck circumference
- Narrowed airway
- Family history
- Use of alcohol or sedatives before bed
- Smoking
- Nasal congestion
When to see a doctor
See a doctor urgently if:
- Sudden, severe shortness of breath or chest pain
- You stop breathing for more than 10 seconds and have difficulty waking up
Book a routine appointment if:
- You or your partner notice loud snoring with gasping
- You feel extremely tired during the day despite enough sleep
- You have high blood pressure that is hard to control
Diagnosis
Your doctor will ask about your symptoms and may refer you to a sleep specialist. They might ask you to keep a sleep diary or use a home sleep test to monitor your breathing, oxygen levels, and heart rate overnight.
Tests that may be done
- Home sleep apnoea test – a device you wear overnight to measure breathing and oxygen
- Polysomnography – a more detailed sleep study done in a clinic if needed
What to expect at your appointment
You will typically have a test at home or in a sleep lab. It is painless and involves sensors on your body. Results help your doctor decide if you have sleep apnoea and how severe it is.
Treatment
Treatment focuses on keeping your airway open while you sleep and addressing underlying causes.
Self-care at home
- Lose weight if overweight
- Avoid alcohol and sedatives before bed
- Sleep on your side instead of your back
- Keep your nasal passages open with saline sprays or strips
Medical treatments
The most common treatment is a CPAP (Continuous Positive Airway Pressure) machine. It delivers a steady stream of air through a mask to keep your airway open. Other options include oral appliances that reposition your jaw or tongue, and in some cases, positional therapy. Do not start any specific device without a doctor's recommendation.
When is surgery considered?
Surgery is rarely the first option but may be considered if other treatments fail. Options include removing enlarged tonsils or adenoids, or procedures to stiffen the soft palate. Surgery is usually only for specific anatomical issues.
Living with this condition
Living with sleep apnoea means managing your treatment, like using a CPAP machine every night, and making lifestyle changes to improve your sleep.
Lifestyle tips
- Establish a regular sleep schedule
- Create a comfortable, quiet bedroom
- Avoid heavy meals, caffeine, and alcohol before bedtime
- Exercise regularly to maintain a healthy weight
Diet and exercise
A balanced diet and regular exercise can help you lose weight or maintain a healthy weight, which can significantly reduce sleep apnoea symptoms. Even moderate weight loss can make a big difference.
Mental health and emotional wellbeing
Sleep apnoea can affect your mood, causing irritability, depression, or anxiety due to poor sleep. It is important to talk to your doctor if you feel this way. Treatment often improves mood as sleep quality improves.
Prevention
While you cannot always prevent sleep apnoea, you can reduce your risk by maintaining a healthy weight, avoiding smoking, limiting alcohol, and sleeping on your side.
Complications
If left untreated
- High blood pressure
- Heart disease
- Stroke
- Type 2 diabetes
- Daytime fatigue that increases risk of motor vehicle accidents
- Liver problems
Long-term outlook
With proper treatment, most people with sleep apnoea can control their symptoms and lead a healthy, active life. The key is to get diagnosed and stick with your treatment plan.
