Sleep apnoea signs UK: symptoms, diagnosis and treatment
Obstructive sleep apnoea explained — snoring, daytime sleepiness, health risks, CPAP treatment and when to seek a sleep study.
Sleep apnoea is under-diagnosed in the UK. Partners often notice it before patients do — and untreated apnoea raises cardiovascular risk.
Key symptoms
- Loud snoring with witnessed pauses
- Gasping or choking arousals
- Unrefreshing sleep and daytime sleepiness
- Morning headaches and poor concentration
Who is at higher risk
- Obesity and larger neck circumference
- Men and post-menopausal women
- Alcohol before bed
- Nasal obstruction
Diagnosis — sleep study required
Home sleep studies or hospital polysomnography measure apnoea severity (AHI score). Online questionnaires cannot diagnose apnoea safely.
Treatment options
CPAP — positive airway pressure during sleep — gold standard for moderate-severe disease.
Weight loss — improves mild apnoea; see weight management.
Mandibular advancement devices — for mild cases or CPAP intolerance.
Urgent reasons to seek help
Falling asleep driving, severe daytime sleepiness, or apnoea with heart failure — GP referral promptly.
Book a GP consultation to discuss referral.
Who should skip this?
Skip buying a CPAP off a marketplace without a diagnosis. Skip sleeping tablets as a first answer to loud snoring and daytime sleepiness — they can make apnoea worse. Seek urgent care if you fall asleep while driving. GP suits witnessed pauses, choking at night, severe sleepiness. Skip that route if occasional snoring with no daytime symptoms.
NHS, high-street pharmacy, or online clinic?
GPs refer for sleep studies. Online clinics are not a substitute for diagnosing apnoea. Weight, alcohol and sleeping on your back are levers while you wait, not a complete treatment. GP suits witnessed pauses, choking at night, severe sleepiness. Skip that route if occasional snoring with no daytime symptoms.
How should you choose a route?
| Option | Best for | Skip if |
|---|---|---|
| GP | Witnessed pauses, choking at night, severe sleepiness | Occasional snoring with no daytime symptoms |
| Do not drive sleepy | Anyone nodding off at the wheel — stop driving and get help | N/A — this is safety, not optional |
| Lifestyle while waiting | Weight, alcohol reduction, side-sleeping | You are using lifestyle to avoid a needed sleep study |
What should you expect if you go online?
A partner’s description of pauses is useful. You may need a sleep study. Untreated apnoea is a blood-pressure and driving issue, not a joke about snoring. GP suits witnessed pauses, choking at night, severe sleepiness. Skip that route if occasional snoring with no daytime symptoms.
What should you do next?
If you fall asleep while driving, stop driving and see a GP. Do not buy a breathing machine off a marketplace. Night-time antihistamines are not apnoea treatment. Ask a partner whether they have seen pauses or choking. Weight, alcohol and sleeping position can help while you wait for a sleep study — they do not replace one. Sanara compares online clinics for other conditions; we are not a sleep laboratory. If daytime sleepiness is new and severe, that is NHS this week, not a supplement. DVLA rules can apply once you have a diagnosis — that is another reason not to self-treat from a shop. Snoring alone is not a diagnosis. A clinic that sells a machine without a study is selling hardware, not care. Children who snore loudly and stop breathing need paediatric advice, not an adult online pathway. Partner links are marked *. If a partner has filmed pauses in breathing, take that to a GP rather than a shop. Sanara does not sell machines and will not pretend a nasal strip is a sleep study. Do not drive if you cannot stay awake in daylight — that is a safety rule, not a lifestyle tip.

Frequently asked questions
What are the warning signs of sleep apnoea?
Loud snoring with breathing pauses, gasping at night, daytime sleepiness despite sleep, and morning headaches — especially with obesity or large neck size.
Is sleep apnoea dangerous?
Untreated moderate-severe sleep apnoea increases risk of high blood pressure, heart disease, stroke and road accidents from sleepiness.
Can sleep apnoea be treated online?
Diagnosis requires a sleep study — not online pills alone. Online GPs can refer and discuss weight management; CPAP is prescribed after formal diagnosis.
Does losing weight cure sleep apnoea?
Weight loss improves mild apnoea for many people but moderate-severe cases often still need CPAP even after weight loss.
Can an online clinic diagnose sleep apnoea from a form?
No. They can ask screening questions. Diagnosis needs appropriate testing. Be wary of anyone posting a machine without a pathway.
Are night-time antihistamines a treatment?
Nytol-type pharmacy tablets are for short-term insomnia in some adults, not for apnoea. They can sedate you without treating airway collapse.
