Sleep Apnoea Symptoms: Warning Signs Checklist for Partners
Sleep apnoea symptoms are mostly invisible to the person who has them, because they happen while asleep. The short answer: loud snoring broken by silent gaps and a gasp, plus a dull, sleepy day, is the pattern worth taking to a doctor. A partner’s notes are often the most useful evidence in the room.

What actually happens in sleep apnoea?
When you fall asleep, the muscles around the throat relax. In most people the airway stays open enough. In someone with sleep apnoea the airway narrows or closes for a short time, breathing stops or becomes shallow, and the body briefly wakes itself to restart it. The person usually does not remember any of this. They remember only that they slept eight hours and feel as though they slept three.
The NHS describes the main night time signs as breathing that stops and starts, gasping, snorting or choking noises, loud snoring and waking often. Because the sleeper is the last to know, the people who share the room tend to notice first.
What are the warning signs a partner might notice?
These are the things worth watching for on a few different nights, not just one bad one:
- Snoring that is loud and steady, then suddenly goes quiet.
- A silent gap, then a snort, gasp or choking sound as breathing restarts.
- Restless sleep, with lots of turning or sitting up.
- Sleeping with the mouth wide open.
- Heavy sweating at night. This is a commonly reported sign, though many other things also cause night sweats.
A snore on its own is very common and usually harmless. What raises the question is the combination: snoring plus pauses plus a tired day. The NHS snoring page says to see a GP if snoring is affecting your life or your partner’s, if you feel sleepy in the day, or if your breathing seems to stop and start during sleep.
What does it feel like in the daytime?
The NHS lists very tired days, trouble concentrating, mood swings and waking with a headache. Add a few things that people often put down to “just getting older” or “work stress”: a dry mouth on waking, nodding off in meetings, in front of the television, or at a red light, and needing a long afternoon sleep that does not seem to refresh you.
One thing to hold lightly: every item in that list also has other causes, including plain short sleep, depression, thyroid problems and several medicines. A symptom list can tell you it is time to ask, but not what the answer is.
Who is more likely to have it?
The NHS lists these as raising the chance: being overweight, a large neck, older age (though children and young adults can have it too), a family history, alcohol and smoking, large tonsils or adenoids, sleeping on the back, and lung disease such as COPD.
That list answers two questions people often ask. First, thin people can have sleep apnoea. Weight is one risk factor among several, so a slim build does not rule it out, especially if the jaw is small, the tonsils are large or the family has a history. Second, women are not exempt. Women may describe it less as loud snoring and more as poor sleep, morning headaches, low mood or constant tiredness, so it is easy to miss. If your own pattern fits the checklist below, mention it clearly rather than assuming it is something else.
The five minute recording that helps your doctor
Ask your partner, or prop a phone on the bedside table, to record about five minutes of the loudest snoring. Then note the clock time of any silent gap that ends with a gasp or snort. A short clip of that pattern tells a doctor more than a description like “I snore a bit”, and it spares the sleeper from having to argue the case. Record on two or three different nights, and one on a night you slept on your back.
The one page sheet to bring to the appointment
Copy this onto paper, fill it in over a week, and take it along. It takes a partner about two minutes each morning.
| What to write down | Example entry |
|---|---|
| Loudness of snoring (quiet, loud, heard through a wall) | Loud, heard in the next room |
| Gaps in breathing and roughly how often | Three or four silent gaps, each ended by a gasp |
| Position when it was worst | On the back |
| Waking, choking or sitting up at night | Woke twice sounding breathless |
| Morning state (headache, dry mouth, unrefreshed) | Headache, dry mouth |
| Daytime sleepiness, 0 (none) to 10 (struggling to stay awake) | 7, dozed after lunch |
| Alcohol, late meal or a cold that night | Two cups of tea, no alcohol |
How is sleep apnoea tested?
A GP may refer you to a sleep clinic. According to the NHS, you wear devices overnight that record your breathing and heartbeat. This is usually done at home, though some people stay overnight in the clinic. The result gives an AHI score, which counts breathing interruptions per hour. The NHS bands are 5 to 14 for mild, 15 to 30 for moderate and over 30 for severe. Nothing painful is involved: sensors, a finger clip and a belt are typical.
The test is the thing that answers the question. Online quizzes and phone apps can prompt a visit but cannot confirm or exclude anything.
What makes the signs worse in the short term?
- Sleeping flat on the back, which lets the tongue and soft tissues fall backwards.
- Alcohol close to bedtime, which relaxes throat muscles further.
- A blocked nose from a cold or allergy.
- Going to bed far short of sleep, then paying it back in a heavy, deep sleep that leans on the airway.
These are reasons for a night to be worse. They are not reasons to delay the visit. For the practical sides of snoring itself, our guides on snoring fixes, side sleeping and sleep studies and on the best sleeping position go through positions and gadgets, and the snoring, apnoea and weight loss post covers the weight link.
This page cannot tell you whether you have sleep apnoea and it is not a diagnosis. See a GP if breathing seems to stop and start in sleep, you wake gasping or choking, or you are tired through the day despite enough hours in bed. If you doze off while driving or at a red light, or you nearly did, do not drive until a doctor has assessed you: the NHS says that if excessive sleepiness is confirmed you must not drive until it is under control, and local licensing rules apply. Untreated sleep apnoea can become serious, so a persistent pattern should not be left to “see how it goes”. Do not use mouth tape, sedating sleep aids or alcohol to force sleep while the cause is unknown. Treatment is decided by a doctor after testing.
What else does disturbed breathing connect to?
Poor, broken sleep can push up blood pressure readings, which is covered in poor sleep and blood pressure. Professional drivers have extra reason to be careful, and long drives and driver health goes through the road side of it. Sleep apnoea is one possible explanation, among others, for sleep that does not refresh.
Sleep apnoea symptom questions people ask
What are the symptoms of sleep apnoea?
The main ones are loud snoring, breathing that stops and starts, gasping or choking noises and frequent waking, along with heavy daytime tiredness, poor concentration, mood swings and morning headaches. A partner is usually the first to notice the night time signs.
Do I have sleep apnea if I snore?
Not necessarily, since many people snore without having it. Snoring becomes a reason to ask a doctor when it comes with pauses in breathing, gasping, or sleepiness during the day.
Can thin people have sleep apnoea?
Yes. Weight is only one risk factor, and a slim person can still have it because of throat shape, large tonsils, back sleeping, alcohol, age or family history.
What are sleep apnoea symptoms in women?
Women often describe unrefreshing sleep, morning headaches, tiredness and low mood rather than a loud snore, which means it is sometimes missed. If the checklist above fits, say so plainly to the doctor.
How is sleep apnoea tested?
You wear sensors overnight that record breathing and heartbeat, usually at home, sometimes in a sleep clinic. The result is an AHI score that grades it as mild, moderate or severe.
Can you stop breathing in your sleep?
Yes, in sleep apnoea breathing can pause repeatedly for short periods and then restart, often with a gasp. The person usually has no memory of it, so someone else has to see it.
Are morning headaches a sign of sleep apnoea?
They can be one of the listed signs, but headaches have many causes. A headache on waking, along with snoring and pauses and a tired day, is worth mentioning to a doctor.
Does sleep apnoea go away?
It does not reliably go away by itself, and it should be assessed by a doctor. Some contributors, such as alcohol near bedtime or back sleeping, can be changed, but a doctor decides what treatment fits after a test.
Should I see a doctor or just try a snoring device?
If there are gasps, pauses or daytime sleepiness, see a doctor first. A device may quiet the sound but would not tell you whether breathing is being interrupted.
