An estimated 18% of adults in France live with sleep apnea, a condition often going unnoticed and, crucially, undiagnosed. That’s according to Dr. Frédéric Le Guillou, a pneumologist-allergologist and president of the association Santé respiratoire France, who describes the disorder as “completely underestimated.” The lack of awareness and diagnosis means that roughly 70% of those who have sleep apnea remain unaware of their condition, and only about 30% of those who need treatment are actually receiving it.
Sleep apnea isn’t simply about snoring; it’s a serious health concern with potentially far-reaching consequences. It occurs when breathing repeatedly stops and starts during sleep, depriving the body of oxygen. Often, individuals are unaware they’re experiencing these pauses in breathing, especially if they sleep alone. “It’s often the spouse who notices and reports it,” explains Dr. Le Guillou. Recognizing the signs, however, is the first step toward diagnosis and treatment.
The symptoms of sleep apnea manifest both during sleep and throughout the day. Common nighttime indicators include loud, habitual snoring, a restless sleep pattern, a sensation of choking or gasping for air during sleep, and frequent nighttime urination. Daytime symptoms often include excessive fatigue and sleepiness, morning headaches, difficulty concentrating or remembering things, and a decreased libido. If you experience several of these symptoms, particularly if you have risk factors like being overweight or obese, consulting a healthcare professional is essential. A quick self-assessment can be done using the Epworth Sleepiness Scale, which can help gauge your level of daytime sleepiness.
The Cardiovascular Risk Connection
Sleep apnea is far more than just a sleep disorder; it’s a significant risk factor for serious health problems. Dr. Le Guillou emphasizes that it’s “the biggest cardiovascular risk factor,” even surpassing hypertension and high cholesterol. Untreated sleep apnea triples the risk of heart attack and stroke, and is also linked to an increased risk of depression and accidents – both on the road and in the workplace. The repeated drops in blood oxygen levels associated with sleep apnea put a strain on the cardiovascular system, contributing to these increased risks.
Fortunately, effective treatments are available, but they are typically reserved for individuals with moderate to severe sleep apnea, or those with moderate apnea who are experiencing significant health consequences or have pre-existing heart conditions. A diagnosis is the crucial first step. The diagnostic process usually begins with a referral from a general practitioner to a specialist, such as a pneumologist.
Diagnosing Sleep Apnea: From Home to the Lab
“Generally, the patient is referred by a general practitioner. Then, a sleep recording is performed by a trained healthcare professional,” like a pneumologist, explains Dr. Le Guillou. In most cases, this involves a home sleep apnea test, known as a polygraphy. This test involves wearing sensors that monitor breathing patterns during sleep. The patient installs the sensors themselves, under the guidance of a healthcare professional, and then sleeps in their own bed. In some cases, a more comprehensive test called polysomnography may be necessary. This can also be performed at home, but provides a more detailed analysis of sleep stages and physiological functions. These tests determine the severity of the sleep apnea and whether treatment is needed.
Two primary treatments are currently used: oral appliances (mandibular advancement devices, or MADs) and continuous positive airway pressure (CPAP) therapy. CPAP involves wearing a mask over the nose or mouth during sleep, which delivers a constant stream of air to retain the airway open. Approximately 2 million people in France are currently treated with CPAP machines.
Understanding the Different Types of Sleep Apnea
While often used interchangeably, it’s important to understand there are different types of sleep apnea. The Sleep Foundation details three main types: obstructive sleep apnea (OSA), central sleep apnea (CSA), and mixed sleep apnea. OSA, the most common form, occurs when the muscles in the back of the throat relax and block the airway. CSA is less common and involves the brain failing to send proper signals to the muscles that control breathing. Mixed sleep apnea is a combination of both.
The treatment approach will vary depending on the type and severity of sleep apnea. For example, oral appliances are often effective for mild to moderate OSA, while CPAP is typically recommended for more severe cases. Lifestyle modifications, such as weight loss and avoiding alcohol before bed, can also help manage symptoms.
Early detection and treatment of sleep apnea are critical for preventing long-term health complications. If you suspect you may have sleep apnea, don’t hesitate to discuss your concerns with your doctor. Taking proactive steps to address this often-overlooked condition can significantly improve your quality of life and protect your overall health.

The next step in raising awareness about sleep apnea will likely involve continued efforts by organizations like Santé respiratoire France to educate the public and healthcare professionals about the importance of early detection and treatment. Further research is also needed to develop new and improved therapies for this widespread condition. If you are concerned about sleep apnea, please discuss your symptoms with your doctor and consider taking the Epworth Sleepiness Scale to assess your level of daytime sleepiness. Share this information with your friends and family to help spread awareness about this often-underestimated health issue.
