Psoriasis is a chronic skin disease that currently affects an increasing number of people.Psoriasis is manifested by the appearance of red bumps on the skin;it is popularly known as “scaly lichen”.The skin turns red and itchy, accompanied by a burning sensation.Lesions range from small to widespread and systemic.Typically, lesions occur on the scalp, arms, shoulders, back, groin, palms, and soles of the feet.Psoriasis of the joints, bones, nails, external genital organs and internal organs is also found, but these forms are diagnosed quite rarely.Signs of psoriasis also include:
- Cracks appear on the skin, causing pain and discomfort;
- The structure of the nail is broken;
- Dry skin, leading to death and peeling of skin cells;
- Blisters appear on the surface of the feet and the inside of the hands;
- Forms red spots that cause intense itching.They are swollen masses covered with a white scaly membrane.
Patients with psoriasis often experience periods of nervous tension, depression, and low self-esteem.
If psoriasis is not treated promptly, symptoms such as fever, damage to the nail surface and bone fractures may occur, signaling a complication of the disease.In such a situation, qualified medical assistance is simply necessary.
Because this disease is quite common, people need to know the main reasons why psoriasis appears.
Causes of psoriasis - main theories

Modern medicine still does not have a definite answer to the question: "Why do psoriasis patches appear on the skin and where does this disease come from?"
In addition to the appearance of psoriatic plaques on the skin, other functional disorders are also diagnosed in the body, which are disruptions in the functioning of the immune, nervous and endocrine systems.
The causes and mechanisms of psoriasis have been studied for more than a century, but science still does not have an accurate definition of the specific cause of psoriasis on the skin;There are some types of theories that all medical professionals rely on:
- Immune theory;
- Genetic theory;
- Neurological theory;
- Virus theory.
Each theory requires detailed consideration.
Immunity theory
Many famous scientific researchers believe that when the body's immune system is weakened, autoimmune invasion will occur, as a result of which the human immune system will reject its own skin cells, mistaking them for foreign cells.One cannot disagree with this;Certainly, with a decrease in immunity, a disease such as psoriasis on the skin can begin to develop, but one cannot help but take into account many other factors that can also contribute to this.
Genetic theory
It has been proven that more than 55% of the population with this disease has a blood relative with the same disease.If one parent in the family has psoriasis, the chance of the child having the disease is 25%; if both parents have the disease, the chance of the child having the disease is 70-75%.Despite such impressive numbers, official medicine does not consider genetic factors as the main cause of psoriasis.

Neurological theory
The main theory that most doctors rely on is the neurological theory.According to this theory, psoriasis occurs with increased nervous excitement, frequent stress, problems in work and personal life and the development of neurosis.
The nerve disorder leads to narrowed blood vessels and impaired blood flow to the skin, thus forming papules.
It is also established that with frequent experiences, nervous shocks, stress when changing places of residence, irritation and rash formation on the skin occur.
Virus theory
Many doctors say that psoriasis can also occur against the background of an existing viral disease or after an illness.But they still haven't been able to find the specific virus that causes psoriasis.There is no doubt that after a viral illness or during an illness, the immune system weakens and the likelihood of developing psoriasis increases.
The hypothesis about the emergence of skin psoriasis raises many questions and doubts in medicine, because psoriasis is not considered a disease that can be transmitted from sick people to healthy people.In the entire history of medicine, doctors have not recorded a single case of psoriasis.
Key factors
There are several factors that can lead to the development of the disease that causes psoriasis:

- Skin trauma;
- Increased nervous excitement, frequent stress;
- Viral and infectious diseases;
- Use antibiotics, vitamin complexes;
- Changes in climatic conditions, especially if a drier climate changes to a wetter one;
- Dermatological diseases: fungal diseases, dermatitis;
- Improper diet: eating a lot of sweets, fatty foods, alcoholic beverages;
- 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 susceptible to this disease should protect themselves from exposure to these factors.
The main cause of psoriasis is considered to be a complex deterioration of the human body, due to the influence of not one, but many factors at once.
A very important fact is that psoriasis is non-contagious in nature, meaning it is not transmitted in any way.With the many different reasons psoriasis occurs, everyone can be at risk.
It can occur in both adults and children, even infants.The earlier psoriasis occurs, the more severe it can become throughout life.Therefore, it is very important to take care of your health, eat properly, not abuse alcohol, protect yourself from skin damage and periodically strengthen the immune system.
