Is Sleep Apnea Genetic?

No one likes interrupted sleep. However, some people’s bodies turn against them when it’s time for a proper nightly rest. Sleep apnea often goes underdiagnosed despite its prevalence. It causes repetitive sleep interruptions, which snowball to have adverse health effects.

From daytime sleepiness to cardiovascular issues, sleep apnea is often attributed to lifestyle factors such as smoking or obesity. But is sleep apnea genetic as well? The answer is yes; it does have a hereditary factor.

Emerging research shows that genetics play a significant role in sleep apnea development. Understanding if your genes are to blame is important, as it can help determine if you’re at risk. So, let’s explore whether sleep apnea can run in the family, its alternate causes, and treatment options.

    Can Sleep Apnea Be Hereditary?

    Yes, sleep apnea, especially obstructive sleep apnea (OSA), can have a hereditary component. Research shows that genetics account for approximately 40% of the risk of developing OSA.

    People with a family history of the disorder are more likely to develop sleep apnea themselves. While sleep apnea is not inherited, such as eye color, familial clustering has been observed. It indicates that shared genetics and environmental factors can contribute to the likelihood of its development. For example, genetics can influence the upper airway anatomy and muscle tone, both of which impact the development of sleep apnea.

    Other Causes of Sleep Apnea

    Genetics alone can lead to sleep apnea; other factors can contribute to the onset and severity of this issue.

    1. Obesity
      Excess weight, especially around the neck, can obstruct the airway during sleep.
    2. Age and Gender
      Sleep apnea is more common in older adults and is prevalent in men more than women. Although, women nearing or with menopause may also be equally at risk.
    3. Anatomical Features
      Some physical traits like a thick neck or a small lower jaw can increase the risk of airway obstruction.
    4. Lifestyle Factors
      Smoking, alcohol consumption, and sedative use can worsen symptoms by relaxing throat muscles or irritating airways.

    How Sleep Apnea Can Be Treated

    Sleep apnea treatment can vary according to the severity and underlying causes. For some, lifestyle changes such as weight loss, exercise, and positional therapy might help with symptoms.

    For others, a CPAP or continuous positive Airway Pressure device can deliver a steady stream of air to keep the airway open while sleeping. Custom-fitted orthodontic appliances can also correct the position of the jaw to maintain an open airway.

    For severe cases, surgery might be considered to remove excess tissue from the throat or to correct anatomical abnormalities that are causing the disorder.

    End Note

    Sleep apnea can be genetic. However, it’s not as straightforward as inheriting the same eye or hair color. Various environmental and lifestyle factors also influence it. People without a family history of sleep apnea can still be at risk if the combination of environmental or lifestyle factors is met.

    Observing any changes and difficulties during sleep is important, as sleep apnea can be to blame. Research shows that approximately 22 million Americans suffer from sleep apnea, according to the American Sleep Apnea Association.

    So, if you’re having trouble sleeping, don’t rule out the possibility that you might have sleep apnea. It’s important to seek evaluation from dental experts like Epic Dental.
