What is Obstructive Sleep Apnoea
As a result of the continual awakenings caused by OSA, those affected suffer from severe sleep deprivation and fatigue. Unfortunately, people with this condition are often completely unaware that they have been woken up throughout the night and are oblivious to the reason for their tiredness.
Untreated OSA may lead to serious health problems such as high blood pressure, heart attack and stroke. OSA also causes memory loss, poor concentration, morning headaches and sexual dysfunction.
Sleepy drivers are the cause of many accidents on our roads.
The signs and symptoms of obstructive and central sleep apneas overlap, sometimes making the type of sleep apnea more difficult to determine. The most common signs and symptoms of obstructive and central sleep apneas include:
- Excessive daytime sleepiness (hypersomnia)
- Loud snoring, which is usually more prominent in obstructive sleep apnoea
- Episodes of breathing cessation during sleep witnessed by another person
- Abrupt awakenings accompanied by shortness of breath, which more likely indicates central sleep apnoea
- Awakening with a dry mouth or sore throat
- Morning headache
- Difficulty staying asleep (insomnia)
- Attention problem
Many people don't think of snoring as a sign of something potentially serious, and not everyone who has sleep apnea snores. But be sure to talk to your doctor if you experience loud snoring, especially snoring that's punctuated by periods of silence.
