How does one differentiate normal snoring from sleep apnea?

Doctor's Answers 1

Thanks for the D2D. Snoring is not just noise. Not all who snore have sleep apnea, but snoring is a sign that you may have sleep apnea. In Singapore, a recent study found that 90% of those with already moderate to severe sleep apnea did not know that they had sleep apnea!

Sleep apnea happens when there is a block in the airway that results in significant oxygen desaturation in the blood. To differentiate snoring from sleep apnea, a definitive sleep study is needed.

People who snore loudly, stop breathing during sleep, have sleepiness and fatigue in the day, and have structural obstructions in the nose and throat, low lying soft palate and large tonsils, less developed chin and prolapsed base of tongue will have increased risks of sleep apnea.

Compared to Malays and Indians, Chinese have the highest sleep apnea rates, despite them having the lowest obesity rates. This is likely due to their craniofacial proportions that predispose to a narrower airway.

Many of my patients seek treatment for sleep apnea late, when they already have hypertension, heart disease and diabetes that are hard to control despite medications and lifestyle changes, partly due to an undiagnosed sleep apnea.

What are some recommendations on CPAP machine in Singapore for sleep apnea?

There are so many types of CPAP machines on the market and internet, it can be bewildering. The most important consideration should be that it is something tailored to your specific type and severity of sleep apnea. The mask choice, fitting, fine tuning of settings, type of CPAP, even the size and portability of the machine is important to optimise use and effectiveness. The after sales support is very important too. For that reason, I do not advise that the CPAP be bought on the internet, as your doctors will not be able to support you in the use of the CPAP after that.

What are the steps to get Sleep Apnea diagnosed and treated in Singapore?

Thank you for your questions. As your questions have been answered well by Dr Chua, I shall not be repetitious. However, I would like to elaborate on why snoring is a significant symptom and the assessments involved for a snorer. Snoring is a common symptom and a local study has shown that up to 30% of Singaporeans snore. It is a significant symptom for 2 main reasons: 1. If the snorer has a bed partner, he/she will be frustrated and possibly sleep deprived from the constant or loud snoring. 2.
