SLEEP APNEA RESOURCES
Signs & Symptoms of Sleep Apnea
Recognizing the Warning Signs of Sleep Apnea
Sleep apnea is one of the most underdiagnosed conditions in the United States. The American Sleep Apnea Association estimates that approximately 80% of moderate and severe cases remain undiagnosed. One reason is that the most obvious symptoms — loud snoring and pauses in breathing — happen while you are asleep. Many patients only become aware of the problem when a partner, family member, or roommate notices something wrong.
At Glendale Dental Wellness, Dr. Ivan Chan helps patients identify the signs of sleep apnea and connects them with the diagnostic resources and treatment they need. Understanding what to look for is the first step toward restful sleep and better health.
Types of Sleep Apnea
Not all sleep apnea is the same. There are three distinct types, each with different underlying causes:
- Obstructive Sleep Apnea (OSA) — the most common form, accounting for approximately 84% of diagnoses. OSA occurs when throat muscles relax during sleep, causing the soft palate, tongue, and tonsils to physically block the airway.
- Central Sleep Apnea (CSA) — less common, occurs when the brain fails to send the correct signals to the muscles that control breathing. The airway is not physically blocked. CSA is more frequently associated with heart failure, stroke, and opioid use.
- Complex (Mixed) Sleep Apnea — a combination of both obstructive and central sleep apnea, typically identified when a patient treated for OSA with CPAP continues to have central apnea events.
When to Seek Evaluation
You should consider a sleep apnea evaluation if you experience any combination of the following:
- Your partner reports loud snoring or witnessed breathing pauses during your sleep
- You wake up feeling unrefreshed despite sleeping 7-8 hours
- You experience excessive daytime sleepiness that interferes with work, driving, or daily activities
- You wake frequently during the night, especially with a gasping or choking sensation
- You have morning headaches that resolve within a few hours of waking
- You have been told you have high blood pressure, particularly if it is resistant to medication
Early diagnosis and testing is essential because untreated sleep apnea carries significant health risks that worsen over time. The good news is that effective treatment — including oral appliance therapy — can dramatically improve your sleep, energy, and long-term health.
Common Symptoms of Sleep Apnea
Sleep apnea symptoms fall into two categories: nighttime symptoms often observed by a bed partner and daytime symptoms experienced by the patient.
Loud, Chronic Snoring
Especially snoring heard through walls or closed doors, or that worsens when sleeping on your back. This is the most commonly recognized warning sign.
Breathing Pauses & Gasping
A partner may notice you stop breathing for several seconds and resume with a gasp or snort. Sudden awakenings with a choking sensation also indicate airway collapse.
Excessive Daytime Sleepiness
Feeling tired despite a full night's sleep, or falling asleep during passive activities like watching television. This is one of the most dangerous symptoms due to drowsy driving risk.
Morning Headaches
Caused by fluctuating oxygen levels and disrupted sleep. These headaches are typically dull, widespread, and resolve within a few hours of waking.
Cognitive & Mood Changes
Difficulty concentrating, memory problems, irritability, anxiety, and depression are significantly more common in patients with untreated sleep apnea.
Restless Sleep & Night Sweats
Frequent tossing and turning, nighttime urination, dry mouth or sore throat upon waking, and excessive sweating from the body's stress response to oxygen drops.
Risk Factors for Sleep Apnea
Fat deposits around the upper airway are the greatest risk factor for OSA. Approximately 70% of OSA patients are overweight or obese.
A thicker neck (greater than 17 inches in men or 16 inches in women) is associated with a narrower airway and increased risk.
Sleep apnea risk increases with age, peaking in adults over 50. Men are two to three times more likely to develop it than premenopausal women.
A naturally narrow airway, enlarged tonsils, recessed jaw, or large tongue all increase OSA risk. Dr. Chan evaluates these during your dental exam.
These substances relax throat muscles more than normal sleep does, increasing the likelihood and severity of airway obstruction.
Having close relatives with sleep apnea increases your risk. Smokers are three times more likely to develop OSA due to airway inflammation.
Frequently Asked Questions About Sleep Apnea Symptoms
Can you have sleep apnea without snoring?
Yes. While snoring is the most recognized symptom of obstructive sleep apnea, not everyone with sleep apnea snores. Central sleep apnea, in particular, often occurs without significant snoring. Other symptoms like excessive daytime sleepiness, morning headaches, waking up gasping, and difficulty concentrating may be present without noticeable snoring. This is why a comprehensive evaluation is important if you experience any combination of sleep apnea symptoms.
How do I know if my snoring is a sign of sleep apnea?
Snoring that is loud enough to be heard through closed doors, accompanied by witnessed pauses in breathing, gasping or choking during sleep, or excessive daytime sleepiness is more likely to indicate sleep apnea. Simple snoring that is soft and consistent without breathing pauses is less concerning but should still be evaluated if it disrupts your sleep or your partner's sleep. A sleep study is the only definitive way to distinguish between primary snoring and sleep apnea.
Can children have sleep apnea?
Yes, sleep apnea affects children as well as adults. In children, the most common cause is enlarged tonsils and adenoids. Symptoms in children may differ from adults and can include mouth breathing, bedwetting, behavioral problems, poor school performance, and restless sleep. If you suspect your child may have sleep apnea, consult with their pediatrician and visit our office for an oral evaluation.
What makes sleep apnea worse?
Several factors can worsen sleep apnea symptoms. Sleeping on your back allows gravity to pull the tongue and soft tissues backward, further blocking the airway. Alcohol consumption relaxes throat muscles and worsens obstruction. Weight gain increases fatty tissue around the airway. Nasal congestion from allergies or illness forces mouth breathing, which collapses the airway more easily. Certain medications, particularly sedatives and muscle relaxants, can also worsen sleep apnea.
Can sleep apnea develop suddenly or does it come on gradually?
Sleep apnea typically develops gradually over time as risk factors accumulate — weight gain, aging, and changes in muscle tone all contribute slowly. However, some patients notice a seemingly sudden onset of symptoms, often triggered by significant weight gain, a change in sleeping position, or hormonal changes such as menopause. In reality, the underlying airway narrowing was likely present before symptoms became noticeable.
Should I see a dentist or a doctor for sleep apnea symptoms?
Both play important roles. Your primary care physician or a sleep medicine specialist will order a sleep study to diagnose sleep apnea and determine its severity. A dentist trained in sleep medicine, like Dr. Chan, evaluates your oral anatomy for airway factors, provides oral appliance therapy for treatment, and monitors your progress. We work collaboratively with your physician to provide comprehensive care.
