But do you know that some people who snore may be or risk of dying from Obstructive Sleep Apnea or its complications! This condition affects between 5 – 10 % of population; common among adults but also affect children.

Why do people snore?

Snoring and Apnea

Snoring and Apnea

Normally, during sleep, the muscle which controls the tongue and soft palate hold the upper airway open. If the muscles relax the airway becomes narrower, partially blocking off the air passage. Breathing in makes the soft or floppy part of the throat vibrates, making the noise of snoring. If the throat is particularly narrow, or the muscle relaxes too much, the airway can become completely blocked, preventing breathing. This condition is Obstructive Sleep Apnea (OSA).

What are the symptoms of OSA?

Excessive sleepiness
many people with OSA are very tired during the day. They may fall asleep at work, while driving the car, in the middle of a conversation, while reading or watching television.

Loud snoring
Loud snoring especially when interrupted by silence followed by gasps is a common feature of OSA. This is often confirmed by spouse

Choking at night
People with OSA may experience choke at night which interrupts their sleep

Poor concentration
Due to lack of quality sleep, people with OSA may have poor concentration affecting their quality of work. This may progress to poor memory and intellectual function. OSA may be associated with high blood pressure, heart disease & stroke, which can be fatal.


How is the condition diagnosed?

To confirm the diagnosis, people with suspected OSA need to see a doctor who can refer him/her to a sleep clinic/hospital. A sleep study is an overnight test where patient’s sleep will be monitored in term of brain wave activity, breathing pattern, oxygen level, eye and leg movements, body position and the degree of snoring.

How is OSA treated?

Mild OSA may improve with weight reduction. If OSA is caused by obstruction (due to enlarge tonsils or deviated nose) surgery will often cure the condition. However the great majority of cases will be most effectively treated with Nasal Continuous Positive Airway Pressure (CPAP). This machine helps to keep the upper airway open while sleeping by delivering pressurized air through a nose mask. Most people experience immediate and total relief of their symptoms with CPAP treatment.
