Can Sleep Apnea Be Caused by Genetics?

Sometimes, despite our best intentions, our genetics get the best of us. Whether you have curly hair and wish it were straight, crooked teeth which erupted that way against your will, or a sleep disorder that you definitely didn’t ask for, the traits we get (and don’t get) are often out of our control. Here’s a closer look at how genetics could be behind your sleep apnea, and what you can do to finally get a good night’s sleep despite them!

What is Sleep Apnea?

Sleep apnea is a disorder that causes you to repeatedly stop and restart breathing throughout the night. Known as apneas, these episodes can occur 100 times an hour, making it impossible to get a continuous night’s rest. This in turn results in daytime problems like exhaustion, depression, cognitive failure, and the worsening of myriad conditions including diabetes, Alzheimer’s disease, high blood pressure, and even certain cancers.

Could My Sleep Apnea be Genetic?

There are many reasons people develop sleep disorders. The most common type, obstructive sleep apnea (OSA) is due to an obstruction in the airway, which can be affected by your weight, age, gender, opioid use, and even genetics if you have the gene RMST/NEDD1.

Conversely, central sleep apnea (CSA) occurs when the brain improperly signals the body to breathe; however, while this is not usually hereditary, it still may be influenced by genetic factors such as the presence of certain heart conditions.

Is it Possible to Treat Sleep Apnea Without CPAP?

No matter what is causing your sleep apnea, it is important to treat it promptly to improve your symptoms and reduce your risk of serious side effects like hypertension, depression, and cognitive failure. While in decades past the treatment of choice was usually CPAP, in recent years patients have found great success with oral appliance therapy from their dentist. These convenient, custom-made devices fit comfortably into your mouth to prop your airway open manually while you sleep, allowing you to get a proper night’s rest without the use of awkward masks, tubes, and machinery.

Remember, while your genes may be behind your blue eyes and deep laugh, no matter what’s causing your sleep apnea, relief is possible! To learn more about oral appliance therapy and see if it’s right for you, schedule a consultation for sleep apnea treatment with your dentist today!
