What Causes Snoring & Obstructive Sleep Apnoea (OSA)?
Excessive bulkiness of nose tissues. Snoring can also be caused by a blocked nose, resulting in breathing from the mouth. This may cause excessive breathing effort, which results in the collapse of soft tissues in the throat. A blocked nose may result from enlarged inferior turbinates, a deviated nasal septum or sinusitis.
Floppy soft tissues in the throat and weak tongue muscles. People with these conditions may result in their tongues falling backwards into the airway and their throat tissues at the side being drawn in during sleep, blocking the airway. This results in vibration of the tissues during breathing, leading to snoring.
How Is Snoring & Obstructive Sleep Apnoea (OSA) Treated?
Surgical methods. The type of surgery performed depends on the level of blockage or narrowing in the upper airway. Some of the surgeries may include sinus surgery, adenoidectomy (removal of adenoid), tonsillectomy (removal of tonsils) or tongue base reduction surgery to remove the tissues at the back of the tongue to reduce tongue bulkiness and open the airway
How Is Obstructive Sleep Apnoea (OSA) Diagnosed?
The following examinations may be conducted to diagnose OSA:
Physical examination. The doctor may do a physical exam and inquire about your symptoms and medical history. They may also conduct flexible nasendoscopy (study of your throat and nose using a small lighted tube with a camera at the tip) to evaluate the potential sites of narrowing in the upper airway.
Polysomnography (PSG). Polysomnography is a lab sleep examination that measures oxygen levels and brain waves to determine the causes of sleep disruption.
Home sleep study (HST). This is a self-performed study that is used to diagnose sleep apnoea.
What Is Snoring & Obstructive Sleep Apnoea (OSA)
Snoring is the rattling or snorting noises a person makes during breathing while sleeping.
Obstructive sleep apnoea is associated with interruptions in breathing during sleep, causing the body to receive less oxygen and waking up frequently at night. Obstructive sleep apnoea is caused by an obstruction of the airways, leading to snoring, restlessness and gasping for air during sleep.
