The Pause Between Snorts: A Practical Guide to Sleep Apnoea Assessment

Snoring is often treated as a joke, a family trait or an unavoidable feature of middle age. For many people it is none of those things clinically. In some cases it is the audible part of repeated upper airway narrowing during sleep, and the distinction between ordinary snoring and obstructive sleep apnoea matters because untreated apnoea is associated with daytime sleepiness, blood pressure that is difficult to control and wider cardiometabolic risk. The aim here is not to alarm every snorer in the household. It is to set out a measured triage: what to notice, what to mention to a GP, and what the assessment pathway in the UK actually involves.

When bedroom noise becomes a clinical question

Ordinary snoring tends to be steady and rhythmic. The snorer may wake with a dry mouth, but they generally feel refreshed and function normally during the day. The picture changes when the airway closes repeatedly, oxygen levels dip and sleep is fragmented without the person realising it. Features that raise suspicion include a partner witnessing pauses in breathing followed by a snort, gasp or choke; restless or unrefreshing sleep despite adequate time in bed; morning headaches; poor concentration; irritability; and daytime sleepiness that intrudes on reading, watching television or driving. Nocturia, or waking repeatedly to pass urine, can also be part of the pattern.

A bed partner's account is often more useful than the snorer's own recollection. If you sleep alone, a simple voice recording or a partner's occasional observation can help, but consumer apps are not diagnostic and should not replace clinical assessment. The key message is that bedtime noise is a clinical signal, not a personality trait, and it deserves a conversation rather than resignation.

The STOP-BANG questions in plain English

STOP-BANG is a screening aid used to structure that conversation. It is not a diagnosis, and it can over-flag people who have several risk factors but no actual apnoea. Used sensibly, it helps a clinician decide who should be referred for further testing.

• S — Snoring. Do you snore loudly enough to be heard through a closed door?
• T — Tiredness. Do you feel tired or sleepy during the day, most days?
• O — Observed apnoea. Has anyone seen you stop breathing during sleep?
• P — Pressure. Do you have high blood pressure, treated or untreated?
• B — BMI. Is your body mass index above 35 kg/m²?
• A — Age. Are you over 50?
• N — Neck. Is your neck circumference greater than 40 cm, roughly 16 inches?
• G — Gender. Are you male?

A score of three or more suggests intermediate risk; five or more suggests higher risk. The tool is deliberately blunt, and it is best used with a clinician who can weigh the answers against your symptoms, examination and medical history. It is a prompt for referral, not a verdict.

What your GP is likely to do

A GP will take a focused history, including your sleep pattern, alcohol intake, medications such as sedatives, and any safety-sensitive work or driving. They may use the Epworth Sleepiness Scale, a short questionnaire that asks you to rate the likelihood of dozing in eight everyday situations. Scores above 10 suggest excessive daytime sleepiness. Like STOP-BANG, it is supportive rather than definitive.

Examination may include weight, neck circumference, blood pressure and a check of the upper airway. If moderate or severe apnoea is suspected, or if there are safety concerns such as sleepiness while driving, the GP can refer you to a sleep service. In the NHS, the first investigation is often a home sleep study, sometimes limited-channel respiratory polygraphy or overnight oximetry. These tests measure breathing, oxygen levels and effort while you sleep in your own bed. Waiting times vary considerably by area, so it is reasonable to ask your GP about the local pathway and expected timeline.

If you have excessive sleepiness, do not drive while sleepy and seek advice about your obligations. The DVLA has rules for obstructive sleep apnoea that may apply, and a GP can advise on fitness to drive.

Blood pressure that will not settle

Obstructive sleep apnoea is a recognised contributor to resistant hypertension and to a loss of the normal overnight dip in blood pressure. If your blood pressure remains high despite three or more agents, including a diuretic, or if home readings look stubbornly elevated despite good adherence, apnoea is worth considering. Not every case of resistant hypertension is caused by sleep apnoea, but treating coexisting apnoea can produce a modest and clinically useful reduction in blood pressure. This is one reason the condition sits comfortably within a cardiometabolic as well as a sleep-focused view of health.

CPAP and mandibular devices: realistic expectations

Continuous positive airway pressure, or CPAP, remains the most effective treatment for moderate to severe obstructive sleep apnoea. It delivers pressurised air through a mask to keep the airway open. It is not a quick fix: success depends on mask fit, humidification, trial and error, and consistent use. For many people it substantially improves sleepiness, quality of life and blood pressure. The NHS provides CPAP for confirmed apnoea, though ongoing support and review vary locally.

Mandibular advancement devices are oral appliances that hold the lower jaw forward during sleep. They are an option for mild to moderate apnoea, or for people who cannot tolerate CPAP. They should be made and fitted by a dentist with training in sleep medicine. NHS availability is patchy, and side effects such as jaw discomfort or dental changes need discussion. Lifestyle measures matter too: weight loss where relevant, reducing evening alcohol, avoiding sedative sleeping tablets, and positional therapy for people whose apnoea occurs mainly on their back. Surgery is reserved for selected cases.

A sensible next step

If your snoring is accompanied by witnessed pauses, unrefreshing sleep, morning headaches or daytime sleepiness, book a GP appointment. Take a partner's observations, a medication list and recent home blood pressure readings if you have them. Do not buy a consumer gadget in place of assessment, and do not assume that nothing can be done. Obstructive sleep apnoea is common, treatable and worth taking seriously. The pause between snorts is not a reason to panic; it is a reason to ask a clinical question.
