Psoriasis is a chronic dermatological disease that is currently affecting more and more people.Psoriasis is manifested by the appearance of red papules on the skin;It is popularly called “psoriasis”.The skin becomes red and itchy, accompanied by a burning sensation.Lesions range from localized to extensive and generalized.Lesions most commonly occur on the scalp, arms, shoulders, back, groin, palms, and soles.Psoriasis of the joints, bones, nails, external genital organs and internal organs also occurs, but these forms are diagnosed quite rarely.Signs of psoriasis also include:
- The appearance of cracks in the skin that cause very unpleasant pain;
- The structure of the nails is disturbed;
- Dry skin, which causes skin cells to die and flake off;
- The appearance of blisters on the surface of the feet and the inside of the hands;
- Formation of red spots that cause severe itching.They are swollen structures covered with a white, scaly film.
Patients with psoriasis often spend long periods of time in aggressive nervous tension, suffer from depression and have reduced self-esteem.
If psoriasis is not treated in a timely manner, symptoms such as fever, damage to the nail surface and joint fractures may occur, which indicate a complication of the disease.In such a situation, qualified medical assistance is simply necessary.
Since this disease is very popular, everyone needs to know the main reasons for the appearance of psoriasis.
Causes of psoriasis – main theories
In modern medicine there is still no clear answer to the question: “Why do psoriasis plaques appear on the skin and where does this disease come from?”
In addition to the appearance of psoriasis plaques on the skin, other dysfunctions in the body are also diagnosed, namely the functioning of the immune, nervous and hormonal systems.
The causes and mechanisms of psoriasis have been studied for more than a century, but science does not yet have a precise definition of the specific cause of skin psoriasis;There are different types of theories that all medical professionals rely on:
- immune theory;
- genetic theory;
- Neurogenic theory;
- Viral theory.
Any theory requires detailed consideration.
Immune theory
Many well-known scientific researchers claim that when the body's immune system is weakened, autoimmune aggression occurs, as a result of which the human immune system rejects its own skin cells, confusing them with foreign ones.One can only agree with that;Undoubtedly, with a decrease in immunity, a disease such as skin psoriasis can develop, but one cannot 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 suffering from this disease have blood relatives suffering from the exact same disease.If one parent in a family suffers from psoriasis, the probability of this disease occurring in children is 25%, and if both parents are sick, the probability of this disease occurring in children increases to 70-75%.Despite these impressive figures, official medicine does not consider genetic predisposition to be 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 excitability, frequent stressful situations, problems at work and in personal life, and developed neurosis.
Neurosis causes blood vessels to narrow and blood flow to the skin to weaken, causing papules to form.
It has also been noted that frequent worries, nervous shocks, stress when changing place of residence, irritation 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 an illness.However, they still failed to find a specific type of virus that would cause psoriasis.Undoubtedly, the immune system weakens after a viral illness or as the disease progresses and the likelihood of psoriasis increases.
This theory of the occurrence of skin psoriasis raises many questions and doubts in medicine, since 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.
Main factors
There are a number of 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, particularly when 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.Therefore, people predisposed to this disease should protect themselves from exposure to these factors.
The main cause of psoriasis is considered to be a complex failure of the human body, which is caused by the influence not of one, but of several factors at once.
A very important fact is that psoriasis is not contagious, meaning it is not transmitted in any way.Given the variety of reasons for the appearance of psoriasis, any person can be at risk.
It can occur in both adults and children and even infants.The earlier psoriasis occurs, the more serious it can become later in life.Therefore, it is very important to take care of your health, eat right, do not abuse alcohol, protect yourself from skin injuries and regularly strengthen the immune system.
