I remember my wife and I first sharing the news of her diagnosis of obstructive sleep apnea syndrome. “What is sleep apnea syndrome?”, was the common question we received. As of late, the matter of sleep and the consequences of sleep deprivation have been coming to the forefront of public discussion and scrutiny. Some companies have even started to screen for it for roles that require operating heavy machinery. But why so much hubbub? After all, sometimes you sleep well and sometimes you don’t. It’s okay to be tired in the day sometimes…after all there’s just so much to do! Right?!
Sleep apnea syndrome is a very serious medical condition. It can make a big difference to your day-to-day quality of life and deserves attention. Guess what the word ‘apnea’ means. It’s from Greek apnoia, meaning ‘absence of respiration’. It refers to the cycle of cessation and resumption of breathing during sleep, which has very serious consequences for your health. In reality,?there are really around three (3) types of sleep apnea syndrome, but obstructive sleep apnea (OSA) is argued to be the most common. This type is characterised by a partial (or sometimes complete) closure of the airway due to a physical obstruction. Usually, a very reliable sign of this is…you guessed it…snoring. While snoring may not necessarily mean that one has sleep apnea (after all, it could point to Upper Airway Resistance Syndrome instead), it can indicate that there’s a serious problem with respiration during sleep that needs to be thoroughly examined.
What Causes Obstructive Sleep Apnea Syndrome?
As we said before, OSA is caused by an actual blockage of the airway. How that occurs is fairly specific. As you fall deeper and deeper into sleep, the muscles at the back of the throat start to lose their tone or rigidity. As a direct result, the structures they support– ie the tongue and soft palate start drooping into the air passage, gradually obstructing the flow of air. The snoring sound that accompanies this is really caused by the vibration of the tissues in the passageway as the sleeper tries to breathe. It’s comparable to drinking through a straw that’s becoming ever narrower…a condition which actually puts the body under stress!
When the brain suddenly realises that it’s not getting enough oxygen, it sends a ‘wake-up call’ in the form of our?good old stress hormone, adrenaline. This wakes us up just enough to cough (and snort sometimes), thus clearing the airway. This is so brief that many of us do not recall the event. But then we settle back down to sleep, only for it the pattern to recur. This could go anywhere from five (5) times per hour in mild cases, to more than thirty (30) times in severe instances. It’s important to remember that, when left untreated, sleep apnea can actually worsen so it makes sense to be proactive in its treatment.
What Are The Signs I May Have It?
The scary thing about OSA is that many people do not know they have it. During my days as a bachelor, I did not know I snored until I accidentally snored myself awake! Women in particular tend to have hangups about snoring because it’s not deemed “ladylike”. While men are more likely to be affected by sleep apnea, women also need to realise that they can be affected, even if they do not show outward signs of snoring.
A few weeks ago, I listened to a podcast by Dr Steven Park titled “The Walking Dead: Sleep Deprived Zombies Are For Real.” During the show, he interviewed Dr Joseph Borelli and they discussed the detrimental effects of sleep apnea on the brain, nervous system and the heart. One of the most important points they mentioned however, was that many of us are accepting of one of the most common symptoms–daytime fatigue–without a hint of concern! Some of us may actually use it validate just how busy we are with our daily duties, and while we may perform excellently on the job, we are failing terribly at sleep. A very simple test for this is whether or not we would fall asleep given the chance. This may also happen in inappropriate situations such as at social events or when driving or operating heavy machinery!
Children are not exempt from the effects of sleep apnea either. Many of us make the mistake of associating snoring with deep sleep, when nothing could be further from the truth (we may even say it’s ‘cute’). A child that snores excessively should really be checked by a sleep specialist so that early remediation can be effected.?Children are less likely to show hypersomnolence (ie excessive sleepiness) in the daytime, and as such most parents wouldn’t necessarily think to have this looked into. The effects however will eventually manifest themselves as the child matures; stunted growth is a very important indicator. According to Wikipedia, this may occur for two (2) reasons:
- the amount of energy burned at night simply trying to breathe may keep a child’s metabolic rate prohibitively high
- obstruction of the nasal passage and upper airway (especially if complicated by bad allergies) may make the experience of eating a total chore
It makes a lot of sense then to keep a watch on your young one(s) for these features as sleep apnea can influence their long-term development.
Alongside excessive daytime sleepiness though, there are many other signs and symptoms. Morning headaches may result due to the persistent state of low oxygen throughout the night. Before learning about sleep apnea syndrome and CPAP my wife and I had almost accepted that her morning headaches were caused by her epilepsy medication. We were looking at the wrong correlation all along.
Insomnia is yet another symptom…one which can start a vicious cycle of sleeplessness. The brain learns to avoid stressors and can actually trigger wakefulness as a way to avoid oxygen deprivation. This makes attempts at sleep very dissatisfying and frustrating, which only serves to trigger the cycle anew.
Cognitive capabilities suffer greatly in sleep apnea sufferers. Do recall that sleep has its own architectural makeup, and each stage is aimed at doing something very specific. One of those stages (deep sleep) controls memory consolidation and maintenance. If you’re getting too little (or too light) sleep, then you are likely to have problems with attention and memory in the medium-term.
Acid reflux (GERD) tends to be an issue that gets glossed over frequently as well. At one point when I was 30 lbs overweight, I had terrible heartburn which I could not figure out. As it turns out, due to the resistance being created at the top of my airway as a result of?my snoring, I was effectively creating a vacuum for my stomach acid. This sucked it all the way up into my throat, causing me a world of problems: nighttime coughs and a dry scratchy throat in the morning being foremost amongst them.
There are many others: anxiety, depression, heart disease, diabetes, hypertension, loss of libido (erectile dysfunction may also present here)…you name it, many of these conditions can be traced back to simply being a bad sleeper. Some unusual secondary conditions may also show up?in persons with sleep apnea, such as postural orthostatic tachycardia (POTS) or atrial fibrillation. If you’ve been diagnosed with either of these, do see a doctor as soon as possible!
Am I At Risk?
You could be at risk due to any of the factors named below:
- Weight. Interestingly enough, weight is one of the first major indicators of poor sleep. Being overweight increases the likelihood of fatty deposits around the neck interfering with airway integrity over the course of the night (a heavier neck makes it harder to breathe). Note however that being thin does not eliminate the possibility of developing sleep apnea, though it may serve to help lessen its effects and enable more rapid benefits to be achieved via treatment.
- Chronic Nasal Congestion. Due to sinusitis, I’m stuffy almost every night. Nasal sprays are therefore my best friends (no kidding). Unfortunately, I fall in the range of persons who may be twice as likely to develop sleep apnea, by virtue of airway restrictions.
- Gender. Males are twice as likely to develop sleep apnea, as against females. It’s tough being a guy!
- Genes. Seriously, just when you thought it couldn’t get worse. Your family history can play a part in indicating whether or not you may develop sleep apnea. Since family lines tend to share developmental traits, it is not uncommon for certain physical features?that may precipitate?the condition to be passed down. A narrow jaw for instance is a common physical feature that may predispose you to sleep apnea. It’s also one of the reasons why dental/orthodontic practices nowadays no longer seek to only carry out procedures that may reduce jaw development (eg. extractions), but also?try to widen the jaw where possible.
- Smoking. Most persons smoke to relax, but unbeknownst to the great majority, their sleep may be suffering. The risk of developing sleep apnea is approximately three (3) times higher in smokers due to inflammation and irritation of the soft tissues in the upper respiratory tract (ie the back of the nasal passage and throat).
- Asthma.?A study done in 2015 determined that asthma sufferers were 40% more likely develop sleep apnea. Treating asthma therefore actually serve to mitigate?sleep apnea’s debilitating effects.
While this list is not exhaustive, it does identify many of the primary concerns that should get you thinking.
Wow…What Should I Do If I Want to Get Checked Out?
Firstly, start a sleep journal. You can find a sample here. This should indicate some specific parameters surrounding your sleep–namely duration, quality, whether or not you had dreams, how many times you may have gone to the bathroom during the night, shortness of breath, morning headaches etc. ?Some say you only need two (2) weeks worth of information in the journal before seeing a sleep specialist, but I would recommend observing your pattern for one (1) month since that would represent a larger period over which you can do some trend analysis.
Your next step would be?to get a referral to a sleep specialist. Said specialist would normally run through a questionnaire with you in order to confirm the status of your condition. It’s very helpful as well to have a spouse or family member along who may be better able to report on how you’re sleeping. When I accompanied my wife, I was able to relate the fact that she would snore loudly and stop breathing from time to time. That was a source of great anxiety for me, sometimes coming into the bedroom and just seeing her lying perfectly still, before suddenly starting to breathe again. Of course, she maintained that she did not snore loudly (go figure) but since she wasn’t the one hearing it, her opinion didn’t count!
Fun fact (…well not really): Did you know that some spouses go partially deaf due to the the snoring of their partner? In particularly bad cases, snoring may enter the decibel range of a chainsaw (121 dB)! For reference, the safe noise limit for our ears is 85 dB…so if you’re being exposed to loud snoring for several hours per night, you may be at risk of hearing damage/loss. Snorers themselves aren’t missing from this equation…they may also suffer noise-induced deafness from their own respiratory noises.
After running through the questionnaire, you may be subjected to a physical exam of your nose, mouth, throat and soft palate. Of particular interest is throughput in the nasal passage, the size of the tongue relative to the jaw, the size of the uvula (which hangs right above the airway) and tonsils as well as?the circumference of the airway itself. Dentists are in a particularly good place to provide this information.
If the outcome points to a moderate or high risk of sleep apnea, the doctor may request a sleep study. The most common type of study is known as a polysomnogram and may be delivered in a lab or at home. This normally involves specialised equipment with sensors that keep track of your heart rate, blood pressure, respiration and oxygen levels throughout the night. In lab studies, you may be put on a CPAP machine for a part of the night in order to verify whether or not your sleep quality?improves. Ultimately, the results will be aggregated, reviewed and scored. Your diagnosis is normally shared with you around 1-2 weeks later.
Can I Just Ignore It And Get On With My Life?
Well you could…but that wouldn’t do you any good. Sleep apnea itself doesn’t kill, but the secondary conditions it provokes very well might. Depending on its severity, it may make it very difficult for you to remain healthy and productive in the medium-to-long term. Here are but a few of the possible complications that accompany sleep apnea:
- Excessive Daytime Fatigue. This is the #1 problem. In persons with post-traumatic epilepsy, this can also be one of the most difficult things to get over since they may also be battling migraines. In the case of my spouse, chronic sleep deprivation actually lowered her seizure threshold, which made it seem as though her drugs had stopped working! We spent nearly three (3) years trying to figure out the problem, and did the worst thing ever–tried sedatives. They only made matters worse. Long and short, was that entire time financially taxing? YES. Could it have been avoided? If we had sorted out her sleep first, also YES!
- Hypertension. Secondary hypertension tends to result from oxygen stress at night. When oxygen levels fall, the body tries to compensate by increasing blood pressure. Ordinarily, this wouldn’t be a bad thing, since it’s the same pathway used when we engage in strenuous exercise. The problem however is that over time the body is conditioned to low oxygen levels at night and elevated pressure ends up being maintained in the day as well. This can cause heart disease and stroke which we’ll discuss next.
- Heart disease and Stroke. Hypertension is a pretty strong risk factor for the development of heart disease. This is once more due to the strain that OSA places on the cardiovascular system. Let’s not forget that cardiac arrhythmias may also result, increasing the likelihood of eventual heart failure.
Once again, this does not represent a comprehensive list of complications. But would you really want to know what further horrors await?
What Are The Options For Treatment?
Before speaking about the medical interventions possible, it’s important that we establish the goals of treating OSA. The aim is do anything possible to help you breathe better during the night by helping to relieve or remove any factors that contribute to resistance in the airway. This will also reduce snoring along with other issues related to sleep apnea such as hypertension and daytime fatigue.
There are four (4) typical ways to treat OSA.
- Lifestyle Changes. This is usually the lowest hanging fruit. Following a program for weight-loss, doing sleep apnea exercises, kicking bad habits such as smoking and drinking, and keeping to a sound bedtime ritual can all help to improve sleep apnea symptoms. Avoiding caffeine and sedatives can also contribute greatly to upping the quality of your sleep at night.
- CPAP. Continuous positive airway pressure is easily the most common treatment for moderate to severe sleep apnea. Essentially it involves a device with a pump and tubing which supplies a variable stream of air in order to keep your airway open at night. Getting one of these usually requires a prescription and it is recommended that either your sleep specialist or a technician configure the device prior to use. It’s not a perfect solution by any means since some persons can’t handle the side effects (which may include headaches, dry or runny nose, sore throat or sensitive skin, particularly around the nose). By and large though, adherence to CPAP can contribute substantially to alleviating issues caused by OSA. Most devices offer a range of accessories so customisations may be all that are needed to resolve matters of discomfort.
- Oral Appliances. These mouthpieces normally come in two (2) primary flavours, either tongue stabilisation devices or mandibular advancement devices. The former pulls the tongue forward to keep it out of the airway, while the latter moves the jaw forward in order to increase the room at the back of the throat. Your dentist may be able to make a custom mold for you in order to facilitate this treatment. Alternatively, there are many OTC solutions available without a prescription, such as the Good Morning Snore Solution. Always consult your specialist before trying those!
- Surgery. Usually done as a last resort, surgical procedures are gaining some popularity as more permanent and lasting solutions. It all depends though on the type of sleep apnea that you suffer from and its severity. Most surgical interventions focus on removing, reshaping or stiffening the soft palate and surrounding structures that may obstruct the airway during sleep. This may also involve removal of the tonsils in children based on the judgment of the physician.
I hope this writeup has helped to shed some more light on the matter of obstructive sleep apnea syndrome. It’s a medical condition that could greatly benefit from more awareness-raising effort and I’d like to play my part in helping to educate everyone. If you or a loved one currently deal with sleep apnea issues, I would love to hear how your treatment is going! Kindly drop me a comment below and I’ll be sure to respond.
Sleep well until next time!
What a great article here, very informative!
Wow can my wife snore and toss and turn all night. I keep telling her she should see her doctor about this but of course, she will argue that she doesn’t snore that much. (yeah right)
So I decided I would do some research myself, which is what brought me here. Your article here has given me some new ammunition to use to get her to the doctor.
Thank you for the great information!
Hi Kim, I’m glad you found this informative! If your wife snores, please make sure she gets that looked into as soon as possible. Upper airway resistance syndrome can develop into sleep apnea which can really make things worse. Do keep me posted on your progress!
Just thought I would let you know that I have finally got her convinced that she should get this look at. I’m so glad I found your article, it will be nice to get a good night’s rest for both of us. 🙂
Hi Kim, I’m so happy to hear that! Knowledge is power so I sincerely believe you folks are now on a path towards better health. Take care and let me know how it goes!
This was a very informative post, thank you.
If I may ask, should anyone who persistently snores be advised to see a physician? My spouse snores like crazy, even when he just falls asleep (like 10 mins into his sleep). I’d even taken a video of him snoring actively for him to admit that he snored. I admit I’d also accidentally snored myself awake, but my sisters (whom I shared the same room with until I got married) had never complained that I snored. My spouse says the contrary.
I don’t know about oral appliances. Since you mentioned consulting a specialist before using them, does this mean it’s not safe for me to buy over-the-counter appliances?
Hi Princila! Yes, if anyone you know persistently snores, they may be experiencing upper airway resistance syndrome without being aware of it. Some may think it’s harmless, but the problem is that this may eventually develop into obstructive sleep apnea which can cause a host of other health issues (eg. hypertension, diabetes, etc).
As for oral appliances, they are safe to try but the reason I indicated consulting your physician is that he may be able to better guide you as to their uses and expected results. So please feel free to to reach out to me if you have any further queries!
I didn’t know that it could be this serious. I have a brother who snores so loud that no one would ever want to sleep in the same room with him.
I thought it is normal for someone to snore. But now I’m really worried for him. I need to get him to see a doctor soon.
Thanks again for this eye-opening post
Yup sleep-disordered breathing at this point could almost e considered an epidemic! Lots of people have upper airway resistance and sleep apnea which can go undetected for years. Please get your brother checked out as soon as is possible. Let me know how it goes!
This is a great article it is very thorough and informative. I have sleep apnea myself and have to use a cpap machine. People just don’t understand how tired you feel all the time when you have this condition and it is not treated. Your article will help people to understand this condition better. Thanks so much.
Hey Marie, I am glad you found this to be informative. Sleep apnea can really get in the way of living a healthy and productive life. Unfortunately the world we live in prioritises wakefulness over proper sleep hygiene. I hope one day we will all be able to appreciate the importance of sleep to our daily well-being and long-term health.
