Stress

Stress is a typical trigger for complaints such as dizziness and nausea in our society today. Permanent or long-lasting stress at work or in the private environment, especially the cardiovascular system is upset, resulting in increased heart rates and high blood pressure. This can damage the organ of equilibrium and thus cause dizziness. The hormones are also affected by chronic stress, which can cause additional symptoms of the gastrointestinal tract (e.g. nausea).

Duration

Dizziness is usually caused by a mismatch between the information that our eyes send to the brain and the information that our vestibular system sends to the brain. A common phenomenon is, for example, dizziness, which can occur even after a concussion. In this case it depends on the severity of the injury.

They can, however, be triggered repeatedly and may accompany affected persons for a lifetime. Dizziness and nausea can also occur after a concussion. In this case it depends on the severity of the injury.

As a rule, the symptoms should not last longer than a few days. However, there are also people who suffer from chronic dizziness. This often occurs in certain situations, so that individual dizziness and nausea attacks last for a few minutes to hours.However, they can be triggered again and again and may accompany affected persons throughout their entire lives.

Causes

The causes of dizziness with nausea can basically be divided into three major disease areas. These include the vestibular, the non-vestibular and the psychogenic caused dizziness. Vestibular dizziness is a dizziness caused by a disorder of the vestibular organ in the inner ear.

The most common cause in this case is a so-called benign positioning vertigo. In a healthy person, the organ of equilibrium consists of sensory cells that can measure both linear acceleration and rotational movements. A special feature of the cells for measuring rotational movements is that they have small crystals on their gel-like coating.

If one or more crystals become loose, they irritate the correct perception of the movement. The result is a short-lasting dizziness after a change in posture, such as turning while lying down. Another cause of a direct disturbance of the organ of balance is damage to the auditory and vestibular nerves.

In principle, it does not matter how and by what means the nerve itself or its course is damaged. From an inflammation of the nerve to a structure that presses on the nerve, anything is possible. If the transmission of information from the vestibular organ is disturbed, the brain cannot process the sensory impressions perceived correctly.

Dizziness appears as a symptom and can be accompanied by nausea as its intensity increases. Depending on the cause, it can be permanent or only occur in attacks. If there is no damage to the organ of balance, doctors speak of non-vestibular causes.

Non-vestibular in this case means that the cause is found somewhere in the body, but not in the inner ear itself. In any case, a physical cause can be found. From a visual defect to a rhythm disturbance of the heart, the causes are widely spread in this area of the disease.

Even a space requirement in the brain, which hinders the processing and filtering of sensory impressions, would be conceivable. All physical causes, however, have in common that they trigger a rotational vertigo. Affected persons feel like they are on a merry-go-round and, depending on the severity of the problem, are not able to fix a point.

The last major area of illness is vertigo, where no physical cause can be found. In the technical terminology it is called psychogenic dizziness. In most cases, the occurrence of vertigo attacks can be assigned to a clear trigger and is usually based on strong psychological stress situations.

A typical example would be the occurrence of vertigo with nausea before an important test. Characteristic of this type of vertigo is that it is a form of vertigo. Those affected therefore feel as if they are on a swaying ship on the high seas.
