Snoring caused by sleep apnea

Snoring, fatigue & related symptoms

Are you trying to stop snoring? Certain sleep apnea symptoms and associated conditions can be a strong indication that you have sleep apnea.

What causes snoring?

Snoring occurs during sleep, when your throat muscles become so relaxed that they can no longer support the airway to stay fully open.

As the airway collapses, each breath of air causes the lining tissue to vibrate and make loud snoring sounds.

How to stop snoring caused by sleep apnea

Some mild snoring can be harmless, and often treated with over-the-counter products like ones which improve your sleep positioning. But when your snoring is loud and accompanied by breathing pauses called apneas – which are periods when you stop breathing and then gasp for air – it can be a sign of sleep apnea.

Apneas can last up to a minute in severe cases and prevent your body from getting enough oxygen. Then your carbon dioxide blood levels rise, signalling to your brain to wake up briefly (and unconsciously), tense your throat muscles and gasp for air.

Sleep apnea interrupts your sleep cycle and can cause you to wake up exhausted, irritable, and foggy.

Many people first suspect they have sleep apnea because their bed partner or children complain about loud snoring

If your snoring is accompanied by apneas and is the result of obstructive sleep apnea, it can almost always be eliminated with sleep apnea treatment.

What are the common sleep apnea symptoms?

If you are experiencing 2 or more of these common sleep apnea symptoms, it may be a sign that you can have sleep apnea:

  • Snoring
  • Breathing pauses (apneas)
  • Gasping for air at night
  • Fatigue throughout the day – sometimes falling asleep while driving or at work
  • Poor concentration
  • Feeling depressed, irritable or moody 4,5
  • Reduced sex drive
  • Using the toilet often at night
  • Nightmares

Is sleep apnea dangerous?

If it is not treated properly, sleep apnea can become more complicated over time and potentially lead to other health conditions.

However, by treating your sleep apnea proactively you may be able to reduce or eliminate the risks of these long-term health conditions:

Type 2 Diabetes 3

If you have diabetes and sleep apnea, not being able to breathe properly at the night can aggravate your diabetes.

The interrupted sleep caused by sleep apnea puts stress on your heart and your body. It can cause your blood sugar levels to rise, potentially leading to insulin resistance. If left undetected and untreated, sleep apnea can worsen your health.
High Blood Pressure (Hypertension)4,5

When sleep apnea causes you to stop breathing at night, your oxygen blood levels can decrease while your carbon dioxide levels build up. Your  heart is forced to work harder to get rid of the carbon dioxide, which can lead to high blood pressure.

Heart Disease 4,5

People with sleep apnea are at a higher risk of experiencing a heart attack while sleeping, or of developing coronary artery disease.
Depression 6

Sleep apnea is sometimes wrongly diagnosed as depression. More than 70% of people with sleep apnea experience symptoms that are depression-like.
Exhaustion

Sleep apnea can cause you to feel  tired and irritable throughout the day. Even if you sleep a full 8 hours, your body is not truly getting the rest it needs.

Weight gain 7

Feeling tired can cause you to eat more than you normally would and lead to weight gain. People who have sleep apnea and adhere to their therapy can experience weight loss and feel less hungry during the day.
