Sleep apnea is a respiratory disorder that occurs at night, often without the person being aware of it. Thousands of Quebecers suffer from it without knowing it. Chronic fatigue, morning headaches, and loud snoring reported by a bed partner are sometimes the only clues. However, untreated, sleep apnea increases the risk of cardiovascular disease, diabetes, and drowsy driving accidents.<\/p>\n
This page explains what sleep apnea is, how to recognize it, how it is screened for, and what treatment options are available in Quebec.<\/p>\n
Sleep apnea is defined by repeated breathing cessations during sleep, lasting at least ten seconds, occurring several times per hour. These respiratory pauses disrupt sleep quality and deprive the brain and organs of an adequate oxygen supply.<\/p>\n
There are three main forms:<\/p>\n
Severity is classified based on the apnea-hypopnea index (AHI): mild, moderate, or severe, depending on the number of respiratory events per hour of sleep.<\/p>\n
Obstructive sleep apnea can affect anyone, but certain factors increase the risk:<\/p>\n
Children can also be affected, often in connection with enlarged tonsils or adenoids.<\/p>\n
The difficulty with sleep apnea is that the affected person sleeps during the episodes and often has no memory of them. It is frequently bed partners or family members who are the first to notice.<\/p>\n
Nighttime symptoms<\/strong><\/p>\n Daytime symptoms<\/strong><\/p>\n Sleep apnea is not just an inconvenience. If left untreated, it is associated with serious health risks:<\/p>\n Initial medical consultation<\/strong><\/p>\n The starting point is a consultation with a doctor, who will assess your symptoms using standardized questionnaires (such as the Epworth Sleepiness Scale or the STOP-Bang questionnaire). A physical examination of the throat, nose, and neck completes the assessment.<\/p>\n Home overnight respiratory polygraphy<\/strong><\/p>\n In many cases in Quebec, screening is done with a portable device that the person uses at home overnight. This device measures airflow, chest movements, oxygen saturation, and heart rate. It is less comprehensive than in-lab polysomnography, but is often sufficient to confirm a diagnosis of moderate to severe obstructive sleep apnea.<\/p>\n In-lab polysomnography<\/strong><\/p>\n The gold standard test is polysomnography conducted in a sleep clinic. It records sleep, breathing, brain activity (EEG), and muscle movements in detail. It is recommended when the diagnosis is uncertain, when central apnea is suspected, or when CPAP titration needs to be performed simultaneously. Waiting times in the Quebec public system can be long\u2014private options exist.<\/p>\n The standard treatment for moderate to severe obstructive sleep apnea is continuous positive airway pressure (CPAP). Worn at night, a nasal or full-face mask is connected to a small machine that keeps the airways open with a continuous stream of air. Once adapted to, it is well-tolerated, eliminates apneas, improves oxygen saturation, and restores sleep quality. The effects on fatigue, concentration, and blood pressure can be remarkable.<\/p>\n In Quebec, the RAMQ partially covers CPAP devices for individuals with a confirmed diagnosis who meet certain criteria. Specific conditions apply\u2014your doctor can inform you about your eligibility.<\/p>\n For mild to moderate sleep apnea, a custom-made oral appliance fabricated by a dentist or orthodontist can reposition the jaw and tongue forward during sleep, thus reducing obstruction. It is less effective than CPAP for severe apnea but is better tolerated by some individuals.<\/p>\n Weight loss, when possible and clinically relevant, can significantly reduce the severity of apnea. Avoiding alcohol and sedatives in the evening, sleeping on your side rather than on your back, and treating chronic nasal congestion are useful complementary measures.<\/p>\n In selected cases, surgical interventions on the upper airway structures (tonsillectomy, uvulopalatopharyngoplasty, nasal surgery, maxillomandibular advancement) may be considered, especially when a specific anatomical abnormality is identified or when CPAP is not tolerated. Surgery is not recommended as a first-line treatment for the majority of patients.<\/p>\n Chronic fatigue, difficulty concentrating, and repeated nighttime awakenings directly impact mood and mental health. Depression and sleep apnea frequently coexist\u2014sometimes in both directions: depression disrupts sleep, and untreated apnea worsens depression. If you are experiencing symptoms of both conditions, it is important to address them with your doctor.<\/p>\n Excessive daytime sleepiness related to untreated sleep apnea poses a real risk to road safety. In Quebec, the Soci\u00e9t\u00e9 de l\u2019assurance automobile du Qu\u00e9bec (SAAQ) requires physicians to report patients whose medical condition may affect their ability to drive. A diagnosis of untreated severe apnea can lead to temporary restrictions on a driver's license until effective treatment is in place.<\/p>\n Consult a health professional if you or your partner notice:<\/p>\n Do not minimize these symptoms. Sleep apnea is a treatable condition \u2014 and treatment can transform quality of life.<\/p>\n Our doctors can assess your symptoms, complete a screening questionnaire with you, and refer you to appropriate tests or specialists.
