Sleep apnoea

The so-called sleep apnoea syndrome (SAS or OSAS for short) is caused by periodically occurring breathing disorders during sleep. It can be a particularly unpleasant complaint for those affected, as OSAS can be characterised by symptoms such as microsleep and daytime sleepiness, right up to concentration problems. Especially the latter can lead to life-threatening circumstances in the wrong situation.

Especially when driving or doing other activities that require our full attention and ability to concentrate, OSAS can thus become very dangerous. It becomes clear how important it is to recognise sleep apnoea syndrome at an early stage and to initiate appropriate treatment measures or therapy. In the following, we inform you about the symptoms and causes of sleep apnoea syndrome.

What causes the symptoms of sleep apnoea?

The short-lived breathing stops, also known as apnoeas in technical language, lead to repeated awakening reactions in the body. Due to the apnoeas, the oxygen content drops while the carbon dioxide content of the blood rises. This triggers an alarm reaction in the body to prevent a further drop in oxygen levels. Thus, sufferers are regularly disturbed in their sleep by the lack of oxygen and the wake-up reactions it causes. Nightly sleep thus hardly fulfils the function of providing the body with rest.

In OSAS, breathing stops at least 10 times per hour for more than 10 seconds. A characteristic feature of sleep apnoea is that sufferers usually do not wake up consciously. Only the pulse rate is increased, along with other bodily functions. This makes it particularly difficult for those affected to identify sleep apnoea as the cause of their pronounced daytime sleepiness. Many people suffer from the symptoms over a long period of time, even though a lack of restful sleep can significantly reduce the quality of life of those affected. Not only can daytime sleepiness and microsleep occur, but depression and cardiovascular disease can also be caused by sleep apnoea. Sleep apnoea syndrome is treatable.

Sleep apnoea - different types and causes

There are two forms of sleep apnoea. The most common form of sleep apnoea syndrome is so-called obstructive sleep apnoea (OSAS). In Germany alone, 1-2% of women and 2-4% of middle-aged men are affected by obstructive sleep apnoea syndrome. This is always anatomically determined and is caused by too narrow airways. Causes can include, for example, a constitutional slackening of the throat muscles or enlarged pharyngeal tonsils. The latter risk factor plays a major role, especially in children. The combination of the narrowed airways and the pharyngeal muscles, which slacken anyway during sleep, can lead to a complete closure of the airways. Thus, the lungs have to create extra negative pressure to ensure that the body continues to be supplied with oxygen. The second, much less common form of sleep apnoea is called central sleep apnoea syndrome. As the name suggests, it is caused by a malfunction of the central nervous system. The brain forgets to breathe. This causes the breathing stops that are typical of sleep apnoea, with the resulting alarm reactions of the body. If both forms of sleep apnoea occur together, it is called mixed sleep apnoea. This can be treated with sleep apnoea surgery.

Do you also suffer from sleep apnoea syndrome? Contact us and make an initial appointment at our SeegartenKlinik in Heidelberg. An initial consultation is covered by both private and statutory health insurance companies.

Sleep apnoea types

Sleep apnoea is a breathing disorder during sleep. Affected people stop breathing for more than ten seconds at least ten times an hour during sleep. When breathing stops, oxygen cannot reach the body, which in turn has a massive impact on health.

The breathing pauses usually last so long that the body of the affected person really sounds the alarm. The person wakes up briefly and catches his or her breath. This process is then repeated several times during the night. This means that they never get a good night's sleep. However, those affected hardly notice the body's wake-up call. However, the consequences are noticeable, for example heart and circulatory diseases, daytime tiredness and even depression can be caused by this disease. But there is help for sleep apnoea. First of all, a distinction is made between the three types of sleep apnoea:

Mixed sleep apnoea

When both central and obstructive sleep apnoea occur in a person, it is called mixed sleep apnoea.

This form of sleep apnoea can be treated with sleep apnoea surgery.

Obstructive sleep apnoea

Obstructive sleep apnoea is by far the most common form of sleep apnoea and is always anatomically determined. More than 80 percent of those affected suffer from the obstructive form of this disease. Because the airways are too narrow and the muscles slacken during sleep, the airways often close completely. The lungs have to create a lot of negative pressure to get enough air. The body is so busy actively breathing that restful sleep is out of the question. The breathing pauses can last several minutes and the body also reacts to the lack of oxygen with a wake-up call and gasps for air. Men in particular suffer from this form of the disease. Due to a different anatomy in the throat area of women, they tend to be spared more often. However, this is only the case until the menopause, after which the differences between the sexes decrease. Can obstructive sleep apnoea be cured?

Bimaxillary advancement can be used for this form of sleep apnoea.

Central sleep apnoea

This form is very rare and is caused by a malfunction of the brain. The central nervous system forgets to breathe, causing a stress response in the body, which reacts with a wake-up call. However, the likelihood increases with age. For example, one in four people over the age of 60 suffers from sleep-disordered breathing. People with this type of disorder often do not snore or do not snore very loudly, so the condition may not even be recognised. Can central sleep apnoea be cured?

The cause of this form of sleep apnoea cannot be treated by bimaxillary advancement.

What are the consequences of sleep apnoea?

Sleep through

Many sufferers cannot sleep through the night. This is because the body regularly wakes up at night to get oxygen.

Increased urge to urinate

Increased urination, also called nocturia, is considered a leading symptom of OSAS. It is not an inevitable symptom of old age.

Heart attack

The body of those affected is supplied with too little oxygen, which reduces the blood supply to the heart. The result is an often fatal heart attack.

Daytime sleepiness

The main symptom of OSAS is severe daytime sleepiness. The chronic sleep deficit is the main culprit. The body cannot recover sufficiently during the night.

Night sweats

Affected people sweat excessively at night. Especially in the neck area, sweat production is greatly increased.


Non-restorative sleep leads to poor monotony resistance. Microsleep can be the result. This is particularly problematic when driving, for example.


Loud snoring also makes for a very restless night for your partner. Quiet and regular snoring, on the other hand, is usually harmless.


The brain of those affected is very poorly supplied with oxygen due to the disease. In combination with constant fatigue, the risk of depression is very high.

High blood pressure

The heart is severely affected by the body's constant stress response and lack of restful sleep. High blood pressure can trigger other very serious diseases.


A reduced oxygen supply to the body causes headaches in patients. Tension during the night, which is associated with breathing pauses, causes, among other things, a pseudo-migraine / CMD complaints.


Strokes are often the result of increased blood pressure. Strokes also usually occur at night or in the early morning.


Caused by the lack of oxygen supply, erectile dysfunction (impotence) is a symptom of untreated OSAS.

Cure sleep apnoea without CPAP mask with causal therapy

The bimaxillary advancement with CounterClockwise rotation eliminates the causes of obstructive sleep apnoea. With the cure of sleep apnoea, you can sleep relaxed through the night again and all symptoms such as headaches, tiredness or increased urination will greatly decrease or disappear completely. Furthermore, the cure of sleep apnoea ensures that the probability of suffering a stroke or heart attack is significantly reduced. The risk of developing depression is also greatly reduced.
