Obstructive sleep apnoea: symptoms, GP assessment and sleep tests
Understand which observations to bring to a GP and what sleep testing can involve. This guide helps prepare the conversation; it does not diagnose sleep apnoea.
Quick answer: recognise the pattern, then seek assessment
Sleep apnoea involves breathing repeatedly stopping and starting during sleep. Loud snoring, witnessed breathing pauses or gasping, together with persistent daytime tiredness, deserve a GP discussion. A checklist or wearable cannot diagnose or exclude it.
When to see a GP
NHS guidance advises a GP appointment for breathing pauses, gasping or choking noises during sleep, or always feeling very tired in the day. Ask someone who has observed your sleep to describe it or attend with you if possible. Do not drive when sleepy.
You do not have to fit a stereotype
NICE includes a broader sleep history: unrefreshing sleep, waking headaches, nocturia, disrupted sleep or insomnia, and concentration or memory problems. Body weight is one relevant factor, but it is not a home rule for deciding who can have sleep apnoea. These symptoms also have other causes.
Prepare a useful observation record
- What was noticed: snoring, a pause, gasping or choking; say if you have no witness.
- How long the pattern has been present and how often it is noticed.
- What happens in the day: unintended dozing, concentration difficulties or morning headache.
- Your usual sleep window, shift work, medicines and any existing treatment.
- Whether sleepiness affects driving or a safety-critical job.
Use the symptom checklist and sleep diary as appointment aids. Do not wait to finish them before getting concerning symptoms assessed.
What happens after referral?
If sleep apnoea is suspected, a clinician may arrange sleep testing. A home test may be suitable, while some people need more detailed assessment. If a test is reported as negative but symptoms continue, ask the referring team what that result rules out and whether further assessment is appropriate. Do not interpret a smartwatch result as a clinical sleep test.
Treatment and mouth taping
Treatment depends on the assessment and may involve measures such as CPAP or other appropriate options. Do not alter prescribed treatment or try to hide a breathing problem with supplements. Before trying mouth tape for snoring, read the evidence and safety questions and discuss the underlying problem.

Frequently asked questions
Can I have sleep apnoea without being overweight?
Body weight is one relevant factor, not a rule that can exclude sleep apnoea. Discuss a concerning breathing and sleepiness pattern with a GP.
Does a low sleepiness score rule out sleep apnoea?
No. NICE says the Epworth Sleepiness Scale should not be used alone to decide whether referral is needed.
Does a home sleep test always settle the question?
No. The referring team should interpret the result alongside symptoms and decide whether further assessment is needed.
