According to the American Sleep Apnea Association, it is estimated that 22 million Americans suffer from obstructive sleep apnea. However, it’s common for sleep apnea to go undiagnosed because most people who have it aren’t aware of their disorder.
Despite the popularity of this disease, most people don’t take the risks associated with sleep apnea serious, and the risks are huge. Research indicates individuals with this sleep disorder have an increased mortality rate due to a higher risk of a stroke or heart attack.
Mattress Advisor set out to understand the causes sleep of apnea, what happens if it goes untreated, and how you can determine if you or a loved one has this disorder. To help answer our questions, we called on the expertise of Dr. Jennifer Le, Diplomate of Dental Sleep Medicine (ABDSM) and practitioner of Wake Dental Sleep in Raleigh, NC.
Obstructive sleep apnea is a serious disorder in which breathing pauses repeatedly for 10 seconds or longer during sleep. It is caused by the collapse and or blockage of the airway.
Patients who suffer from sleep apnea are constantly jerked out of reparative sleep. Not only is sleep disrupted, but so is oxygen flow. Sometimes oxygen flow can be interrupted greater than 10 times in one hour — which is enough times for your body to enter crisis mode.
Sleep apnea can be caused by a few different things:
First and foremost, sleep apnea can be caused by an anatomic issue. Some of these include jaw position, the structure of the soft palate, excessive tissue narrowing the airway, or enlarged tonsils. Anatomic issues can sometimes be genetic.
Another more common cause is being overweight or obese. “When someone is overweight, the extra weight carried in the neck can compress and obstruct the airway,” Dr. Le explains.
Finally, sleep apnea can be caused by inflammation of the soft palate from being sick or eating inflammatory foods.
Dr. Le shared with us the most common symptoms of sleep apnea. These include:
Snoring is known to be something that people poke fun at. “Our society has made snoring something to chuckle about, but it’s not normal,” Dr. Le explains.
What people fail to realize is that snoring is actually a sleep disorder in itself.
“Snoring occurs when there is a partial obstruction to the flow of air through the nose and mouth. The sound occurs when loose structures in the throat, like the uvula and soft palate, vibrate as air passes over them. Snoring can get worse when the muscles in the back of the throat are too relaxed either from drugs that induce sleep or alcohol consumption.”
Snoring is an interruption of you and your partner’s quality of sleep. When sleep is interrupted, you can’t complete your sleep stages, which has various repercussions that we’ll discuss later on.
Snoring is the precursor to sleep apnea and has similar causes. Dr. Le recommends that if you snore every night, you should go to your primary physician and have an open conversation about it. That way, you can work together to rule out other disorders.
Sleep apnea that goes untreated has a number of consequences. Here are a few:
Did you know people who suffer from sleep apnea can’t dream? That’s because restorative sleep is interrupted so frequently, they can’t make it far enough into their sleep cycle where dreaming occurs.
Dr. Le explains that the body uses sleeping hours to repair itself and process what it learned that day. The brain’s ability to compartmentalize information during sleep assists in memory recall. That’s why patients who suffer from sleep apnea have difficulty concentrating or remembering information.
Additionally, lack of sleep causes all sorts of hormones to be out of whack — including cortisol, insulin, leptin and, ghrelin to name a few.

The ramifications of poor sleep are cyclical. Take an overweight individual that suffers from sleep apnea for example. This individual may have sleep apnea due to excess weight that obstructs the airway. Because of their sleep apnea, they suffer from sleep deprivation. Sleep deprivation throws their levels of leptin and ghrelin out of whack, which increases their appetite. The excess calories from unnecessary snacking cause them to put on more weight that may worsen their sleep apnea.
There are many other health risks associated with sleep apnea other than the consequences that come with lack of restful sleep.SRisk of stroke, heart failure, diabetes, depression, high blood pressure, and mental impairment are far more common in people with sleep apnea. Wondering why? Dr. Le explained it like this:
“If the main highway in your city is shut down that creates detours. Meaning traffic is going to be redirected to roads that were never built to accommodate the amount of traffic a highway can accommodate. As a result, these roads start to break down from potholes, pavement deterioration, etc. A similar thing happens if your main airway is obstructed. The body overcompensates for the problem by compromising other systems: blood vessels, organs, etc.”
The goal of any type of sleep apnea treatment is to keep the airway open. With that being said, patients need to know they have options.
One of the most important things Dr. Le stressed to us about treatment options for sleep apnea is that they should be modified to best suit a patient’s needs. For this to happen, patients must see a trained doctor that addresses the issue from a holistic point of view. That includes managing your sleep hygiene*, monitoring weight gain and finding the mode of treatment that works best for you.
*By managing sleep hygiene we mean monitoring your sleep habits. Dr. Le suggests limiting the amount of TV you watch at night, reducing the amount of alcohol consumed before bed and finding the proper mattress to name a few. Basically, create an environment that is conducive to getting the best sleep possible.
Here are some potential treatment options that may be available to you:
Continuous Positive Airway Pressure (CPAP) is considered the standard of care for sleep apnea. However, forced oxygen is of no use if you don’t wear the CPAP.
An alternative to CPAP therapy, for those who do not wear or cannot wear CPAP, is oral appliance therapy. There are a variety of oral appliances available. The choice of which is best for you is based on many factors, including the severity of the sleep apnea, jaw structure and personal preference. Visit Dr. Le’s website to learn more about oral appliance therapy.
On top of oral appliance therapy, here are a few tips Dr. Le recommends to help relieve the symptoms of sleep apnea:
“The sooner you identify sleep apnea the better,” Dr. Le tells us. If sleep apnea runs in the family, keep an awareness that your likelihood to develop it increases.
If you have experienced any of the symptoms listed above and believe you may have sleep apnea, Dr. Le recommends seeing your physician to discuss your sleep health. You may also use an app to record your snoring to help identify whether you have reason for concern. Check out this list of apps that record snoring published by the American Sleep Association to start.
Dr. Le leaves us with this: “Remember that sleep management is a team effort. If your sleeping partner suffers from snoring or sleep apnea, that affects your quality of sleep too.” Don’t be afraid to start a conversation with your bed partner about how your sleeping affects them too. Work together to get the help you need.
Dr. Jennifer Le, DMD, D- ABDSM, CPCC, ACC received her dental degree from the University of Pittsburgh in 2001. She now practices at Wake Dental Sleep in Raleigh, NC. Dr. Le is the Director of the American Board of Dental Sleep Medicine (ABDSM), an independent board of examiners that was established in 2004 for duly licensed dentists who treat sleep-related breathing disorders with oral appliance therapy, an effective alternative treatment to commonly used CPAP machines. Additionally, Dr. Le is Chair of Accreditation for the American Academy of Dental Sleep Medicine (AADSM). We chose to speak to Dr. Le for this campaign given her prestige in the field of Dental Sleep Medicine.
