Psoriasis is a chronic dermatological disease that now affects an increasing number of people.Psoriasis is expressed by the appearance of red papules on the skin;it is popularly called "scaly lichen."The skin becomes red and itchy, accompanied by a burning sensation.Lesions range from precise to widespread and generalized.Most often, lesions occur on the scalp, arms, shoulders, back, groin, palms and soles of the feet.Psoriasis of the joints, bones, nails, external genitalia and internal organs is also found, but this form is diagnosed relatively rarely.Symptoms of psoriasis also include:
- The appearance of cracks on the skin, which causes very unpleasant pain;
- Nail structure is disturbed;
- Dry skin, which leads to the death and peeling of skin cells;
- The appearance of blisters on the surface of the feet and the inside of the hands;
- The formation of red spots that cause severe itching.They are swollen formations covered with a white scaly film.
Psoriasis patients often spend more time in aggressive nervous tension, experiencing depression and lowering their self-esteem.
If psoriasis is not treated in time, symptoms such as fever, damage to the nail surface and joint fractures may occur, indicating complications of the disease.In such a situation, only qualified medical help is needed.
Since this disease is quite popular, everyone should know the main reason why psoriasis appears.
Causes of psoriasis - the main theory

In modern medicine there is still no definite answer to the question: "Why do psoriatic plaques appear on the skin, and where does this disease come from?"
In addition to the fact that psoriatic plaques appear on the skin, other functional disorders are also diagnosed in the body, that is, the function of the immune, nervous and endocrine systems is disrupted.
The causes and mechanisms of psoriasis have been studied for more than a century, but science still does not have a precise definition of the specific cause of skin psoriasis;there are several types of theories that all medical professionals rely on:
- Immune theory;
- Genetic theory;
- Neurogenic theory;
- Viral theory.
Each theory requires detailed consideration.
Immune theory
Many famous scientific researchers claim that when the body's immune system is weakened, autoimmune invasion occurs, as a result of which the human immune system rejects its own skin cells, considering them as foreign.One cannot disagree with this;undoubtedly, with a decrease in immunity, diseases such as skin psoriasis can begin to develop, but one cannot fail to take into account many other factors that can also contribute to this.
Genetic theory
It has been proven that more than 55% of people suffering from this disease have blood relatives with the same disease.If one of the parents in the family has psoriasis, then the probability of this disease occurring in children reaches 25%, and if both parents are sick, then the probability of the disease in children increases to 70-75%.Despite the impressive figure, official medicine does not consider genetic predisposition as the main cause of psoriasis.

Neurogenic theory
The main theory that most doctors rely on is the neurogenic theory.According to this theory, psoriasis occurs with increased nervous excitement, frequent stressful situations, problems at work and in personal life, and developing neurosis.
Neurosis leads to the fact that blood vessels narrow and blood flow to the skin becomes weak, because papules are formed.
It has also been established that with frequent experience, nervous shock, stress when changing residence, stimulation and the formation of skin rashes occur.
Viral theory
Many doctors say that psoriasis can also occur against the background of an existing viral disease, or after the disease.But they still haven't been able to find the specific type of virus that will cause psoriasis.Undoubtedly, after experiencing a viral disease, or during illness, the immune system weakens and the possibility of psoriasis increases.
This theory of the occurrence of skin psoriasis raises many questions and doubts in the medical field, because psoriasis is not considered a disease that can be transmitted from a sick person to a healthy person.In the entire history of medicine, doctors have not recorded a single case of psoriasis infection.
Key Factors
There are several factors that can lead to the development of the disease that causes psoriasis:

- Skin injuries;
- Increased nervous excitability, frequent stress;
- Viral and infectious diseases;
- Use of antibiotics, vitamin complexes;
- Changes in climatic conditions, especially if a drier climate changes to a humid one;
- Dermatological diseases: fungal diseases, dermatitis;
- Wrong diet: a lot of sweets, fatty foods, alcoholic products;
- Changes in hormone levels, especially in women during pregnancy, menopause, and breastfeeding.
Psoriasis can occur under the influence of any of the above factors, so people who are prone to this disease should protect themselves from exposure to these factors.
The main cause of psoriasis is considered to be a complex failure in the human body, due to the influence of not one, but several factors simultaneously.
A very important fact is that psoriasis is not contagious, which means it is not contagious in any way.Given the various reasons why psoriasis occurs, everyone may be at risk.
It can happen to adults and children, even babies.The earlier psoriasis occurs, the worse it can be for life.Therefore, it is very important to take care of your health, eat right, do not abuse alcohol, protect yourself from skin injuries and periodically strengthen the immune system.
