Almost1 in 3 Canadian adults is at risk for sleep apnea. But most of them do not know it.1 Are you waking up tired? Is your partner nudging you at night? Your body may be trying to tell you something.
Most people with sleep apnea do not find out because they stopped breathing. They find out because they are tired every day and do not know why. Does that sound like you?
This page will show you the most common signs of sleep apnea on Vancouver Island. It will help you know which signs to take seriously. And it will show you how to get tested right here on the Island — no ferry, no trip to Vancouver needed.
We will look at nighttime and daytime warning signs. We will cover signs many people miss. We will explain what sleep apnea can do to your heart and brain. And we will show you how sleep apnea testing works right here in your community.
What Are the Most Common Signs That You Might Have Sleep Apnea?
The most common signs that you might have sleep apnea include:
- Loud or frequent snoring
- Waking up gasping or choking
- Feeling very tired during the day, even after a full night of sleep
- Headaches in the morning
- Trouble focusing or forgetting things
- Feeling moody or irritable
- Needing to use the bathroom many times at night
- Dry mouth or a sore throat in the morning
These signs often start slowly. That is why many people across Vancouver Island live with sleep apnea for years before they find out.

Nighttime Signs of Sleep Apnea Most People Do Not Notice Themselves
Here is the problem: most nighttime signs are noticed by a partner, not by the person with sleep apnea. If you sleep alone, these signs may go unnoticed for years. And even if you share a bedroom, your partner may not know that what they see is a health problem.
Signs Your Bed Partner May Notice
- Loud snoring.Not everyone who snores has sleep apnea. But most people with sleep apnea do snore. The snoring often stops and starts again with a gasp or snort.
- Stopping breathing.This is the biggest warning sign. Your partner sees you stop breathing for several seconds — sometimes 30 seconds or more. This can happen dozens or even hundreds of times in one night.12
- Gasping or jolting awake.Your body forces itself to wake up to start breathing again. You may not remember it. But you might sit up suddenly or gasp for air.
- Moving around a lot in bed.Shifting positions often is your body trying to keep your airway open. It is a sign that something is breaking up your sleep.
- Getting up to use the bathroom many times at night.A study in the Journal of Clinical Sleep Medicine links this to sleep apnea. When breathing stops, pressure in the chest tells the kidneys to make more urine.2
Many people come to our team because their partner first raised the concern. If your partner has ever mentioned any of these signs — even once — it is worth looking into.
Daytime Symptoms That Are Easy to Blame on Something Else
Sleep apnea does not just affect your nights. It stays with you all day. The signs are easy to blame on other things. That is why many people in Nanaimo, Campbell River, Courtenay, and across Vancouver Island live with them for years without knowing sleep is the cause.
Here is what to watch for:
- Feeling very tired during the day.Falling asleep while reading, watching TV, or in a meeting is not normal — even if it feels normal to you. The American Academy of Sleep Medicine says daytime tiredness is one of the most common signs of sleep apnea.3
- Trouble thinking clearly or remembering things.Low oxygen levels at night hurt your brain’s ability to focus and remember. A 2020 study in the journal Sleep found that people with sleep apnea did much worse on thinking tests than people without it.4
- Headaches in the morning.Waking up with a dull headache is caused by low oxygen levels overnight. The pain usually goes away within an hour or two of waking up.
- Mood swings, irritability, or feeling low.Bad sleep breaks up your emotions. Many people say they felt short-tempered or sad for a long time before their sleep apnea was found and treated.
- Dry mouth or a sore throat every morning.When your airway is partly blocked, your body breathes through your mouth all night. This dries it out.
Symptom vs. What People Blame It On
| Symptom You Notice | What People Blame It On | What It Might Actually Be |
| Always tired, even after 8 hours of sleep | Getting older, stress, a busy life | Sleep breaks caused by breathing pauses |
| Trouble focusing or forgetting things | Too much screen time, getting older | Low oxygen levels during the night |
| Waking up with a headache | Not enough water, tension, sleeping position | Low oxygen levels overnight |
| Mood swings or feeling irritable | Work stress, life pressure | Not getting enough deep sleep |
| Going to the bathroom 2 or more times a night | Drinking too much water before bed | Nighttime body changes from sleep disruption |
| Dry mouth or sore throat every morning | Seasonal allergies, dry air | Breathing through the mouth all night |
If you see two or more of these in yourself, it is worth talking to a sleep health professional.

When Do Signs of Sleep Apnea Start? (And Who Is Most at Risk)
Many people on Vancouver Island wait too long to get tested. Why? Because they do not think they fit the type. People think sleep apnea only affects older, overweight men who snore loudly. That is not the full picture.
Sleep apnea can start at any age — even in children13 — and more women are being found to have it, especially around menopause.
Key Risk Factors
- Age.Risk goes up steadily after age 40. A 2024 Canadian study found that 28.1% of adults aged 45 to 85 were at risk for sleep apnea. Most of them had no idea.5
- Throat shape and size.A narrow airway, small jaw, or large tonsils can cause the airway to collapse during sleep. This can happen even if you are not overweight.
- Weight.Extra weight — especially around the neck — is one of the biggest risk factors. A neck size over 40 cm (16 inches) in women or 43 cm (17 inches) in men raises the risk.12
- Alcohol and sleeping pills.Both relax the muscles in your throat. This makes it easier for your airway to close during sleep.
- Menopause.Hormone changes during and after menopause relax the muscles in the throat. The National Sleep Foundation says women after menopause have the same sleep apnea risk as men their age.6
- Family history.Sleep apnea can run in families. If a parent or sibling has it, your risk is higher.
- Blocked nose or mouth breathing.When you cannot breathe through your nose, your body adjusts in ways that can close off the airway at night.
In the early stages, the signs are small. A little tiredness. Some snoring now and then. Most people do not feel like it is bad enough to do something about. That is why so many people from Duncan to Campbell River — and everywhere in between — have sleep apnea and do not know it.
What Untreated Sleep Apnea Does to Your Heart, Brain, and Blood Pressure
If you have been putting off getting tested, this is the section to read. Sleep apnea does not just make you tired. Over time, it puts real stress on your heart, brain, and blood pressure.
Key Statistics
| 2–3× higher chance of high blood pressure without treatment | 2.2× higher risk of dying from heart disease | 92.9% of Canadians at high OSA risk have never been diagnosed |
Sources: American Heart Association [7]; Nieto et al., JAMA 2000 [14]; Rizzo et al., Canadian Journal of Public Health 2024 [5]
Your Heart
Every time you stop breathing, your brain sends out a stress signal. Your heart beats faster. Your blood pressure jumps. This happens over and over — sometimes hundreds of times a night. Over the years, this wears on your heart. The American Heart Association links sleep apnea to high blood pressure, irregular heartbeat (AFib), heart attack, and stroke.7,15
High Blood Pressure That Will Not Go Down
Are you taking medicine for high blood pressure but it is not working? Sleep apnea could be the reason. Mayo Clinic says untreated sleep apnea is one of the most common causes of hard-to-control blood pressure.8 Some people see their blood pressure drop once sleep apnea is treated — without changing their medication.
Your Brain and Memory
New research links sleep apnea to faster buildup of plaques in the brain tied to Alzheimer’s disease. Deep sleep is when your brain cleans itself. Every time you stop breathing, that process is cut short. The Alzheimer’s Association says good sleep is important for long-term brain health.9
Drowsy Driving
Transport Canada says tired driving plays a role in about 20% of deadly crashes on Canadian roads.10 For people with untreated sleep apnea, the risk is even higher. Whether you drive the Inland Island Highway toward Nanaimo, commute the Malahat from Duncan, or take the long stretch up to Campbell River or Courtenay, falling asleep at the wheel is a real danger — not a small one.
We often see patients sent to us by a heart doctor. Their blood pressure would not come down with medication. No one had checked for sleep apnea. Once it was found and treated, things improved.

How to Get Tested for Sleep Apnea on Vancouver Island — Your Next Step
If the signs on this page sound like you, the best thing to do is get tested. You do not have to drive to Victoria. You do not need to take a ferry to Vancouver. Here is how it works right here on the Island.
Why Sleep Apps Are Not Enough
Sleep apps on your phone or wrist can track movement and guess at sleep stages. But they cannot measure airflow, oxygen levels, or how many times you stop breathing each hour. Those are the numbers a doctor needs. An app might say your sleep is fine — even when sleep apnea is there.
Home Sleep Test vs. Sleep Lab
Canadian Thoracic Society guidelines say a home sleep test is a good and accurate way to check for sleep apnea in adults who likely have it.11 For most people on Vancouver Island, this means two options:
- Home Sleep Test:You sleep in your own bed with a small device. It checks your airflow, oxygen levels, breathing effort, and heart rate. A professional looks at the results. Most people find sleep apnea testing in Parksville much easier than going to a sleep lab in Nanaimo or Victoria — and far better than travelling to the mainland.
- Sleep Lab Test:You spend a night at a sleep lab. It is more detailed. It is used for complex cases or when a home test is not clear enough. It means sleeping away from home.
What Happens at a Consultation
Getting tested is simple. It follows three steps:
- Talk About Your Symptoms:We have a short chat about what you have been feeling — how long it has been going on and how it affects your day.
- Take a Sleep Test Home:You take a small testing device home for one night. You sleep in your own bed. No hospital stays, no overnight trips.
- Get Your Results:We go through your results in plain language. We explain what was found and what to do next — whether that is CPAP therapy, more testing, or good news that your sleep is fine.
