Sleep Apnea Q & A

What is sleep apnea?

Sleep apnea is a common, but possibly severe sleep disorder that affects approximately 18 million adults across the United States. Sleep apnea can cause your breathing to slow down, or sometimes stop altogether, while you sleep. As your brain registers the absence of oxygen, it stimulates breathing again, prompting you to wake up while you sleep. These lapses in breathing can last anywhere from a few seconds to several minutes, and can occur more than 30 times in a single hour of sleep.

Generally, there are three types of sleep apnea:

Obstructive sleep apnea: The most common form of the disorder, obstructive sleep apnea (OSA) takes place when your tongue and the soft tissues of your throat collapse and block your airway.

Central sleep apnea: This form of the disorder happens when your brain fails to send the appropriate signals to the muscles that control respiration.

Complex sleep apnea syndrome: This rare form of sleep apnea is defined as having both obstructive sleep apnea and central sleep apnea.

What are the potential risk factors for obstructive sleep apnea?

Obstructive sleep apnea is more prevalent in people who are overweight, but the condition can affect people at any age, even children. For example, young children who have enlarged tonsil tissues in their throats may experience obstructive sleep apnea.

Risk factors for sleep apnea include:

  • Being overweight
  • Being male
  • Being over age 40
  • Having a large neck size (17 inches or greater in men and 16 inches or greater in women)
  • Having large tonsils, a large tongue, or a small jaw bone
  • Having a family history of sleep apnea
  • Gastroesophageal reflux, or GERD
  • Nasal obstruction due to a deviated septum, allergies, or sinus problems

What are the symptoms of sleep apnea?


Though a common symptom of sleep apnea is loud, persistent snoring, not everyone who has sleep apnea is a snorer. Other signs and symptoms of sleep apnea include:

  • Episodes of interrupted or stopped breathing while asleep
  • Abrupt awakening that may be accompanied by shortness of breath
  • Waking up in the morning with a dry mouth or a sore throat
  • Chronic morning headaches
  • Excessive daytime drowsiness, difficulty concentrating, or irritability



Signs of sleep apnea in children can include:

  • Sleep-walking
  • ADHD
  • Bed-wetting
  • Growth challenges
  • Hormonal and metabolic problems

Does sleep apnea pose any health risks?

Yes. If you have sleep apnea, chronic, disruptive snoring isn’t the only thing you have to worry about. Untreated sleep apnea can increase your risk of developing insulin resistance and type 2 diabetes, high blood pressure, metabolic syndrome, liver problems, and impotence. Sleep apnea can also make you more likely to experience a heart attack or stroke. With sleep apnea, you’re less likely to experience restorative sleep at night. This lack of rest can cause you to doze off unexpectedly during the day or cause a lack of focus, increasing your risk of accidents on the road or at work.

What are the treatments for sleep apnea?

Once diagnosed with sleep apnea, the best treatment approach will depend on your specific diagnosis, including the type of sleep apnea you have and fully determining the severity.

In conjunction with your doctor, Dr. Wang can thoroughly evaluate the possible causes and recommend a suitable treatment after a sleep study (if needed) is performed. For patients with mild sleep apnea who are looking for a simple and effective solution, Dr. Wang can also provide a wide variety of oral appliances designed to relieve snoring. These appliances, such as a snore guard, are designed to move your jaw into an optimal position to keep your airway open.

You may need to try more than one oral device before finding the one that works best for you. Once you find the best appliance, you’ll still need to follow up with Dr. Wang regularly to ensure that the fit remains appropriate, as well as to reassess your condition.
