What Are the Symptoms of Sleep Apnea?

Sleep apnea is a common sleep disorder that causes breathing to repeatedly stop and start during sleep. Many people who have sleep apnea don’t realize it—yet the condition can significantly impact overall health, energy levels, and quality of life if left untreated. Recognizing the symptoms is the first step toward proper diagnosis and treatment. At Woodfield Dental in London, Ontario, we help patients identify sleep apnea and offer comfortable treatment options, including custom oral sleep appliances.

Key Symptoms of Sleep Apnea

1. Loud or Persistent Snoring

Snoring that is loud, frequent, or disruptive—especially if it wakes your partner—is one of the most common signs of sleep apnea.

2. Gasping or Choking During Sleep

If your airway becomes blocked, the body may suddenly gasp to restore airflow. This may appear as:
  • Gasping sounds 
  • Sudden snorting 
  • Momentary waking during sleep 
In many cases, the sleeper may not even remember it.

3. Excessive Daytime Fatigue

Even a full night of sleep may not feel refreshing. This occurs because the body never reaches deep, restorative sleep. Common signs include:
  • Falling asleep easily during the day 
  • Feeling exhausted or sluggish 
  • Trouble staying awake while driving or working 

4. Morning Headaches

Interrupted oxygen flow during the night may lead to tension-like headaches in the morning.

5. Dry Mouth or Sore Throat

Breathing through the mouth during sleep—especially if airway obstruction occurs—can cause dryness and irritation.

6. Difficulty Concentrating or Memory Issues

Poor sleep can impact focus, alertness, and cognitive performance. You may feel “foggy” or forgetful.

7. Irritability, Anxiety, or Mood Changes

Chronic fatigue affects mental and emotional well-being. Mood swings, stress sensitivity, and frustration may increase.

8. Restless or Disrupted Sleep

Even if you don’t remember waking up, your sleep may be:
  • Light 
  • Interrupted 
  • Broken into short cycles 
This prevents the body from getting the deep, restorative rest it needs.

Who Often Notices the Symptoms First?

Many sleep apnea symptoms—such as snoring and gasping—may be noticed more often by a sleeping partner than by the person experiencing them. If someone has mentioned your snoring or breathing pauses, it’s important to take it seriously.

Why Detecting Sleep Apnea Matters

If left untreated, sleep apnea can increase the risk of:
  • High blood pressure 
  • Heart disease and stroke 
  • Type 2 diabetes 
  • Chronic fatigue-related accidents 
  • Depression and anxiety 
  • Reduced immune function 
Seeking treatment supports better sleep, better health, and better daily energy.

How Sleep Apnea Can Be Treated

At Woodfield Dental, we offer oral appliance therapy, a comfortable and non-invasive alternative to CPAP therapy for many patients. A custom-fitted oral appliance:
  • Keeps the airway open while you sleep 
  • Gently repositions the jaw 
  • Reduces snoring and breathing interruptions 
  • Is easy to travel with and comfortable to wear 
We work in collaboration with medical sleep specialists to ensure accurate diagnosis and personalized treatment.
