Sleep apnea is a serious sleep disorder that often goes undetected, although its symptoms can have a profound impact on health and daily life. Many people with this condition experience interruptions in breathing during sleep, leading to dangerous drops in blood oxygen levels.
Untreated sleep apnea not only affects sleep quality but can also increase the risk of serious complications, such as high blood pressure and metabolic problems. In this article, we explain the signs of sleep apnea to watch for and the most effective treatments .
Is Sleep Apnea a Dangerous Condition?
Sleep apnea is a serious disorder that, if left untreated, can have severe health consequences. This condition is characterized by repeated pauses in breathing during sleep, which reduce blood oxygen levels and put additional strain on the heart and brain. As a result, it significantly increases the risk of life-threatening conditions such as heart attacks, strokes, and high blood pressure.
Furthermore, sleep apnea can lead to cognitive impairment, worsen insulin resistance, cause chronic fatigue, and increase the risk of accidents, while also compromising long-term health. Early diagnosis and appropriate treatment are essential to reduce these risks, improve overall health, and regain a better quality of life.
Risk Factors for Sleep Apnea
Certain risk factors can increase the likelihood of developing sleep apnea, including:
- Excess weight : High body weight increases the likelihood of airway blockage, the main cause of obstructive sleep apnea.
- Thick neck and narrow airways : People with a wide neck or naturally narrow airways are at higher risk of obstruction during sleep.
- Underlying health conditions : Certain conditions, such as high blood pressure, congestive heart failure, and diabetes, increase the risk of developing sleep apnea.
- Lifestyle habits : Smoking and excessive alcohol consumption can promote airway collapse during sleep, thus worsening the condition.

The 6 Most Common Symptoms of Sleep Apnea
1. Loud Snoring
For many patients with sleep apnea, loud snoring is one of the most obvious signs, often noticed first by a bed partner. This snoring occurs during obstructive events, where the upper airways narrow, disrupting airflow.
This symptom is particularly common in obstructive sleep apnea (OSA) and can vary in intensity depending on body position. It is generally more pronounced when the person sleeps on their back or during REM sleep, a phase in which the muscles naturally relax.
2. Respiratory Pauses (Apnea Events)
Pauses in breathing, called apnea events, last from a few seconds to more than a minute. They often result from a collapse of the upper airways or an imbalance between the brain and the respiratory muscles.
These interruptions lead to a drop in blood oxygen levels and an increase in carbon dioxide. In the long term, this oxygen deprivation can have serious consequences , including the development of heart disease, atrial fibrillation, or other cardiovascular complications.
3. Excessive Daytime Sleepiness
Daytime sleepiness is a recurring symptom in people suffering from sleep apnea. It results from fragmented sleep, marked by frequent interruptions that prevent reaching the deep stages of restorative sleep.
This lack of rest can lead to concentration problems, reduced performance at work or school, and an increased risk of accidents. Furthermore, daytime sleepiness can worsen in patients with metabolic syndrome or abnormal cholesterol levels, conditions often associated with untreated sleep apnea.
4. Morning Headaches
Headaches upon waking are common in people with sleep apnea. They result from repeated drops in oxygen levels during the night, which cause blood vessels to dilate and lead to discomfort. This symptom is particularly common in people with complex apnea and can persist without proper treatment.
5. Restless Sleep and Night Sweats
Sleep disturbances, often accompanied by night sweats, are characteristic symptoms of obstructive sleep apnea. When apnea episodes occur, the body reacts by accelerating the transitions between sleep cycles in an attempt to maintain normal oxygen levels. This results in restless sleep, excessive leg and body movements, and increased activation to reopen the airway.
6. Sore Throat or Dry Mouth
People with sleep apnea often wake up with a sore throat or dry mouth, primarily due to mouth breathing. This forced breathing through the mouth occurs when nasal airflow is blocked, often due to nasal congestion or an airway obstruction. Prolonged mouth breathing can not only lead to persistent throat irritation but also worsen discomfort upon waking.

The Different Types of Sleep Apnea and Their Symptoms
Obstructive Sleep Apnea (OSA)
Obstructive sleep apnea (OSA) is the most common type, caused by a relaxation of the throat muscles during sleep, leading to a collapse or narrowing of the airway. This obstruction causes pauses in breathing and is often accompanied by loud snoring, gasping, and choking sounds as the person struggles to breathe.
- Symptoms and Complications: OSA is characterized by repeated pauses in breathing that disrupt sleep cycles, leaving individuals exhausted despite a full night's sleep. These events, which can occur several times an hour, are more common in overweight individuals. Without treatment, OSA can lead to serious consequences such as high blood pressure, heart attacks, or strokes.
Central Sleep Apnea
Central sleep apnea is caused by a malfunction in the brain signaling that controls breathing. Unlike obstructive sleep apnea (OSA), there is no airway obstruction; the brain simply fails to send signals to the respiratory muscles, resulting in pauses in breathing that can last several seconds.
- Symptoms and complications : Signs of central sleep apnea include silent pauses in breathing, often without snoring, making them harder for a sleep partner to detect. This type of apnea is frequently associated with underlying medical conditions, such as heart failure or stroke. Disruptions in blood oxygen levels can also affect areas like the hypoglossal nerve and chest muscles, worsening health complications.
Complex or Mixed Sleep Apnea
Complex apnea syndrome (or mixed apnea) combines features of obstructive and central apnea. This form is more difficult to treat due to the coexistence of symptoms from both types of apnea.
- Symptoms and complications : People with complex sleep apnea experience snoring, pauses in breathing, and gasping, characteristic of obstructive sleep apnea (OSA), but also have periods of interrupted breathing without airway obstruction, as in central sleep apnea. These mixed events require close monitoring to identify the dominant type and tailor treatment. The severity of the disorder can vary depending on the sleep stage and body position.

Diagnosis for People with Sleep Apnea
A sleep study, usually conducted in a specialized center, is the gold standard for diagnosing sleep apnea. During this analysis, professionals monitor key parameters such as brain waves, oxygen levels, breathing patterns, and heart rate. These measurements help identify the type of apnea, assess its severity (mild, moderate, or severe), and develop a personalized treatment plan.
As an alternative, at-home sleep studies offer a more convenient and comfortable option for patients. Thanks to specialized equipment, these studies can be performed from the comfort of your own home while still providing accurate results. La Boîte à CPAP offers this professional service, facilitating rapid diagnosis and effective treatment in the comfort of your own home.
Effective Treatment Options for Sleep Apnea
Sleep apnea treatment is tailored to the severity of the condition. La Boîte à CPAP offers a range of solutions to meet the individual needs of patients:
CPAP (Continuous Positive Airway Pressure) devices
CPAP therapy is the most common and effective treatment for sleep apnea. By delivering a constant, gentle air pressure, it prevents airway collapse and ensures continuous breathing throughout the night. La Boîte à CPAP offers a variety of CPAP devices , allowing patients to benefit from personalized treatment and ongoing support.

Lifestyle Changes
Adopting lifestyle changes can play a vital role in managing the symptoms of sleep apnea:
- Weight loss : Reduces excess tissue around the airways, decreasing the risk of obstruction during sleep.
- Smoking cessation : Reduces inflammation and fluid retention in the airways, thus improving airflow.
- Reducing alcohol consumption : Especially before bedtime, this helps to avoid excessive relaxation of the throat muscles, which can worsen episodes of apnea.
These adjustments not only improve sleep quality, but also contribute to overall health and reduce the need for more intensive treatments.
Positional Therapy and Surgical Options
Some patients experience a worsening of symptoms when sleeping on their backs. Positional therapy can help these individuals find optimal sleeping positions, thereby reducing apnea episodes and improving sleep quality. In cases of severe sleep apnea, surgery may be recommended to remove excess tissue or correct structural problems obstructing the airway.
