Vegetative-vascular dystonia (VVD) is a designation of functional vegetative disorders of various origin and manifestations due to neuro- humoral regulation of autonomic functions.
There are many synonyms for VSD, reflecting its peculiar forms. Synonyms: Neurocirculatory dystonia, Vegetative dystonia, Vegetoneurosis. Studies in this area have proven that with a variety of manifestations of this syndrome, there are a number of common diagnostic signs that indicate the central cerebral, i.e. the regulatory nature of the disorder. Namely – on the dysfunction of the deep zone of the brain, which is called the “limbic-reticular complex” (LRK). LRK is a kind of supercomputer, but with peculiar external and internal harmful influences, its operation may be disrupted. VVD refers to those diseases that can only be determined by symptoms. The fact is that there are no structural disorders in the brain during VVD. Other studies also do not show significant changes in the body. But then a person is sick and does not feel well. In the course of various tests, it was found that with VSD, a delicate balance between the most important parts of the autonomic nervous system: the sympathetic and parasympathetic. Therefore, all the symptoms are based on an imbalance and disharmony of the internal physical and biochemical processes. Clinical Symptoms of VVD. These are Psychological disorders, Neurological, Cardiological, Vascular.
- In the first place – Psychological. GVA is manifested in the form of increased fatigue, psychological vulnerability, personality traits can aggravate (for example, in a person prone to shyness or anxiety, these character traits become more noticeable) .
- In second and third place are Neurocardiological and Vascular Disorders.
The most common manifestations of VSD.
- Heart rhythm disturbances (feeling that the heart is “beating”, “freezing”, etc.), cold hands and feet, excessive sweating, “jumps” in blood pressure, heaviness or pain in the head and temples, fainting.
- With VVD, skin color changes are also observed. The skin becomes pale or cyanotic. And if you draw with a pencil on the skin, then red or white marks appear that do not pass for some time. There are so-called nervous redness: after a person is nervous, red spots appear on the skin of the face, neck, chest, more often this happens in women.
- Externally, the VSD is manifested not only on the skin, but also in a change in the autonomic regulation of the eyes (the pupils dilate and contract), as well as in the degree of dryness or humidity of the mucous membranes. For example, if a person is worried, his mouth is dry.
- Sometimes nervous temperature rises.
- Functional disorders of the activity of internal organs also occur. For example, with stress in the stomach, it may rumble. The urinary system can also respond to stress , urge to urinate becomes more frequent. Metabolism is broken, a person can begin to lose weight.
- People exposed to VVD begin to feel more sharply the weather changes, they become “meteopaths . ” Adequate vascular response to internal processes in the body and external influences are disrupted.
The most striking example is Fainting. In this case, the vessels inadequately respond to fluctuations in the external and internal environment. As soon as a person stands up sharply or in some other way changes the position of the body, he will feel dizzy and darker in his eyes, which in turn can lead to fainting. The fact is that, normally, the heart begins to drive blood through the vessels faster and a healthy person simply does not notice it, because it is all fully regulated by the autonomic nervous system. The vessels narrow and expand exactly to the extent that the body needs at the moment.
With VVD, the vessels do not expand sufficiently or contract more strongly than necessary, which leads to the fact that insufficient oxygen and other necessary substances enter the brain with blood .
He can sometimes feel how his blood pressure rises or falls.
If it is lowered – this is expressed in a weakening of vitality, rapid fatigue, lethargy, poor health, weakness of the whole organism. This is due to the fact that the vascular system does not fully supply the brain with blood.
And with increased pressure, a person feels a headache, dizziness and other ailments. The reason is that blood already enters the brain in excess. Protective spasms of blood vessels occur – the body thus protects the brain from the pressure of excess blood.
Reasons for VSD.
- Genetic predisposition, Sedentary lifestyle.
- VVD can be a consequence of the transferred flu or stress, intoxication, poisoning, concussion.
- But most often there is a mixed origin, when external and internal risk factors are intertwined, and then even in a very physically and mentally strong person, vegetovascular regulation can become unstable and VSD develop.
The main causes of VSD:
- Psychological (overwork, stress, neurosis, depression ),
- Biological (this is a metabolic disorder caused by a variety of diseases: diabetes , other endocrine disorders, infections, obesity, etc.)
The principles of treatment are based on the fact that VVD is a syndrome, i.e. set of symptoms. The treatment is only complex, only the use of several methods is effective.
