Snoring can have a disruptive effect on your patients’ lives. They’re often not the first to realise they have a problem: rather, it’s their bed partner who complains. In a French epidemiologic study conducted in 2007 on 850 participants aged 22 to 66, the prevalence of regular snoring was 34.6%.1
Why do some patients snore?
Both snoring and obstructive sleep apnoea (OSA) have a common origin: the obstruction of the upper airway caused by the relaxation of muscles controlling the soft palate and tongue. In snorers without OSA, the airway is obstructed, but not collapsed, though there are flow limitations. In snorers with OSA, there is a partial or complete collapse of the airway, leading to either:
- An apnoea, which is the cessation of airflow for 10 seconds or more.
- A hypopnoea, which is a decrease in airflow lasting for more than 10 seconds, with a reduction of 30% in airflow and at least 4% oxygen desaturation from baseline.
What causes snoring?
Several factors can increase snoring intensity: fatigue, excess weight, sleeping on the back, and drinking alcohol before going to bed are all conducive to loud snoring. People with enlarged tonsils, an enlarged tongue or excess weight around the neck are also prone to snoring. Even structural reasons like the shape of one’s nose or jaw can cause snoring.
Not all snorers have OSA, but almost everyone who has OSA… snores
Snoring is also the primary4 symptom of obstructive sleep apnoea (OSA) , which is the most common form of sleep-disordered breathing (SDB) . Snoring and sleep apnoea are linked at an alarming rate — 3 in 10 men and nearly 2 in 10 women who are habitual snorers also suffer from some degree of obstructive sleep apnoea.5
Clinical studies show that people with untreated sleep apnoea run greater health risks:
Always make sure you screen your patients for OSA. A correct diagnosis is essential to choosing the most appropriate treatment option. Patients who are throat snorers or who have a mild or moderate level of AHI (less than 30) are candidates for a mandibular repositioning device.

Treatment options for snoring
ResMed has treatment options for throat snorers who have sleep apnoea, as well as for throat snorers who don’t.
Types of sleep apnoea
There are three types of sleep apnoea: Obstructive Sleep Apnoea (OSA), Central Sleep Apnoea (CSA) and mixed or complex sleep apnoea. Each type has distinctive characteristics that enable diagnosis.
Screening and diagnosis
ResMed gives you the tools to screen your patients for sleep-disordered breathing, request a sleep study, and get them diagnosed.
