Frequently Asked Questions

Why is it important?

Unfortunately, those with moderate to severe OSA have a reduced life expectancy. They have a significantly higher risk of developing cardiovascular disease (including ischaemic heart disease and stroke). OSA contributes to the risk of developing diabetes and, for those who are diabetic, OSA worsens control of blood sugar levels.

In addition, there is an association between OSA and a higher risk of motor vehicle accidents. With OSA it is harder to concentrate and remain alert during the daytime, and there are higher rates of anxiety and depression.
