Sleep Apnea Test in London: When Snoring Needs a Proper Assessment
Snoring is common. Waking unrefreshed despite enough time in bed, especially when someone has noticed pauses in your breathing, deserves a closer look. Obstructive sleep apnea is one possible cause. It cannot be diagnosed from snoring alone, and a phone app cannot replace a clinical assessment.
What are the signs of sleep apnea?
A partner may notice loud snoring, breathing pauses, or choking sounds. You may wake with a headache, get up to urinate at night, struggle to concentrate, or feel sleepy despite a full night in bed. NICE advises assessment when two or more suggestive features are present. Sleep apnea can also occur in people who do not feel especially sleepy, so a low sleepiness score does not rule it out.
A clinician should take particular care if you have treatment-resistant high blood pressure, type 2 diabetes, atrial fibrillation, or a safety-critical job. These conditions raise the importance of a proper assessment, but none proves that sleep apnea is the cause.
What happens at a GP assessment in London?
The first step is a sleep history: your symptoms, what a partner has observed, work and driving risks, medication, alcohol use, and other possible causes of tiredness. The GP may use the Epworth Sleepiness Scale and consider STOP-Bang, but these questionnaires are aids, not a diagnosis. Bring a partner's account if available. A brief diary of sleep and waking times can help.
If sleep apnea is suspected, the GP can refer you to an appropriate sleep service for testing. NICE recommends home respiratory polygraphy for suspected obstructive sleep apnea. This records several breathing-related signals overnight. If a simpler test is negative but symptoms remain significant, further testing may still be needed. The sleep study and clinical review establish whether the condition is present and how severe it is. Do not buy a device on the assumption that every snore needs the same test.
What can treatment change?
The plan depends on the result and how symptoms affect your day. Weight management where relevant, reducing alcohol, stopping smoking, and sleep habits can all matter. For some people with symptomatic mild sleep apnea and for people with more severe disease, NICE recommends continuous positive airway pressure (CPAP). The aim is more restorative sleep and safer daytime functioning, with follow-up to check whether treatment is helping. A diagnosis is useful because it connects a symptom to an appropriate treatment rather than offering another generic fatigue supplement.
What if you feel sleepy while driving?
Do not drive when excessive sleepiness makes it unsafe. UK DVLA rules can require notification for certain diagnosed sleep disorders and other prolonged sleepiness conditions. The details depend on your diagnosis, symptoms, and licence type; discuss them with your doctor rather than guessing. If your job involves driving or safety-critical vigilance, say so at the first assessment so the referral can be prioritized appropriately.
A sensible first step
If you are waking unrefreshed, snoring with witnessed pauses, or finding that daytime sleepiness is affecting your life, ask for a GP assessment. At The Online GP by The Wellness, a doctor can review the pattern, consider other causes of fatigue, and advise on a sleep-service referral when indicated. The consultation and any subsequent test or specialist care are separate decisions, so ask about the full cost before proceeding.
