One of the more common sleep disorders, obstructive sleep apnoea is a serious condition that results in the closure of your airways while you are asleep. When your airways collapse, your brain tries to wake you up to get oxygen. For some people, this can happen hundreds of times in a night. It’s so common that as many as one in four men over the age of 30 suffer from it. Let’s evaluate what the causes of sleep apnoea syndrome are.

 

What’s Going On When You Have Sleep Apnoea?

The word ‘apnoea’ translates as ‘stopping breathing’ and is used to describe the episode that occurs when the lungs do not receive enough oxygen. When this happens, the levels of oxygen in your blood drop and you are woken up for long enough to take a breath before falling asleep again.

The results of this sequence, which can happen up to 30 times an hour, mean you do not get a good night’s sleep and will wake up the next day feeling lethargic and groggy. This can affect concentration, as well as interpersonal relationships with your bed partner.

 

How Do You Know If You Have Sleep Apnoea?

Lots of people are not even aware of the disturbances that interfere with a good night’s sleep. In fact, many times it is actually a patient’s bed partner who raises the alarm. 

However, sometimes there are other signs to be seen, heard or experienced:

  • Snoring
  • Teeth grinding and clenching of the jaw
  • Headaches especially in the morning
  • Tiredness and fatigue during the day
  • Concentration and memory problems
  • Feeling emotional/irritable
  • Decreased libido

 

What Are The Causes Of Sleep Apnoea Syndrome?

Sleep apnoea shares some of its causes with those of other sleep disorders. There are a number of factors that can contribute to a person having sleep apnoea. Some potential causes of sleep apnoea syndrome include:

  • Inflammation of your tonsils or adenoids, which can cause pressure in the neck and increase its circumference
  • Structural issues with your head, nose or jaw, such as undershot jaw
  • Being overweight or obese, which adds bulk to your neck, weighing your airways down
  • Neck circumference: a wider neck puts you at greater risk
  • Sleeping flat on your back, as this puts your neck muscles under the pressure of gravity
  • Smoking makes you more susceptible than people who have never smoked
  • Using sedative and sleeping tablets, which can cause your neck muscles to relax and affect the rate at which the brain is able to register the lack of oxygen
  • Genetics and a family history of the disorder make you more prone to it
  • Nasal congestion: if you have seasonal allergies or a cold and your nose is blocked
  • Alcohol consumption and caffeine can also play a role, particularly if you are drinking it in the hours before bed. Alcohol relaxes the muscles of the throat and delays the brain’s response to the lack of oxygen in the body.
  • Problems with the thyroid, such as low production of hormones or the presence of a goitre.
