Snoring and obstructive sleep apnoea syndrome

Snoring is common and can be a symptom or a cause of sleep disturbance. Most people who snore remain perfectly well and don’t feel sleepy during the day, but they may be more sensitive to the effects of alcohol or sedatives.

Obstructive sleep apnoea syndrome

Severe snoring may be a sign of obstructive sleep apnoea syndrome, a condition caused by brief blockages of the upper airway during sleep. You’re more likely to have obstructive sleep apnoea syndrome if you:

  • are obese
  • have a thick neck
  • smoke
  • have diabetes
  • often have a blocked nose.

Obstructive sleep apnoea syndrome can cause long-term (chronic) fatigue. It can be diagnosed by measuring the level of oxygen in your blood while you’re sleeping.

What treatments are there for obstructive sleep apnoea syndrome?

Treatment for obstructive sleep apnoea syndrome can include:

  • controlling your weight
  • avoiding alcohol
  • positive airway pressure (which involves wearing a mask during the night)
  • surgery to clear a blockage in the upper airway
  • drug therapy.
