Psoriasis is a chronic dermatological disease that currently affects an increasing number of people.Psoriasis is expressed by the appearance of red papules on the skin;it is popularly called "like with scales".The skin becomes red and itchy, accompanied by a burning sensation.Lesions range from punctate to extensive and generalized.Most often, lesions occur on the scalp, arms, shoulders, back, groin, palms of the hands, and soles of the feet.Psoriasis of the joints, bones, nails, external and internal genital organs is also found, but these forms are rarely diagnosed.Signs of psoriasis also include:
- The appearance of cracks in the skin, which cause very unpleasant pain;
- The nail structure is broken;
- Dry skin, which leads to the death and exfoliation of skin cells;
- The appearance of blisters on the surfaces of the feet and inside the hands;
- The formation of red spots that cause severe itching.They are swollen formations covered with a white scaly layer.
Psoriasis patients often spend more time in aggressive nervous tension, suffer from depression and lower their self-confidence.
If psoriasis is not treated in time, symptoms such as fever, damage to nail surfaces and joint fractures may appear, indicating a complication of the disease.In such a situation, qualified medical help is simply necessary.
Since this disease is quite popular, everyone should know the main reasons why psoriasis occurs.
Causes of psoriasis - the main theories
In modern medicine there is still no clear 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, namely the functioning of the immune, nervous and endocrine systems is broken.
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 psoriasis of the skin;there are several types of theories that all medical professionals rely on:
- Theory of immunity;
- Genetic theory;
- Neurogenic theory;
- The viral theory.
Each theory requires detailed examination.
The immune theory
Many well-known scientific researchers claim that when the body's immune system weakens, autoimmune aggression occurs, as a result of which the human immune system rejects its own skin cells, mistaking them for foreign ones.We can't disagree with that;Obviously, with a decrease in immunity, a disease such as psoriasis of the skin can begin to develop, but many other factors that can contribute to this cannot be ignored.
Genetic theory
It has been proven that more than 55% of the population suffering from this disease have blood relatives with the same disease.If one of the parents in a family has psoriasis, then the probability that this disease will appear in children reaches 25%, and if both parents are sick, then the probability of the disease in children increases to 70-75%.Despite such impressive figures, 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 appears with increased nervous excitability, frequent stressful situations, problems at work and in personal life and with developed neurosis.
Neurosis leads to the fact that blood vessels narrow and blood flow to the skin weakens, due to which papules are formed.
It has also been proven that with frequent experiences, nervous shocks, stress during a change of residence, stimulation and the formation of skin rashes occur.
The viral theory
Many doctors say that psoriasis can also occur against the background of an existing viral disease, or after an illness.But they have not yet been able to find a specific type of virus that would cause psoriasis.Undoubtedly, after suffering a viral illness, or during the illness, the immune system weakens and the likelihood of psoriasis increases.
This theory of the appearance 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, especially if a drier climate changes to a wetter climate;
- Dermatological diseases: fungal diseases, dermatitis;
- Wrong diet: an abundance of sweets, fatty foods, alcoholic products;
- Changes in hormonal levels, especially in women during pregnancy, menopause and breastfeeding.
Psoriasis can appear under the influence of any of the above factors, so people who are predisposed to this disease must be protected from exposure to these factors.
The main cause of psoriasis is considered to be a complex failure in the human body, caused by the influence of not one, but several factors simultaneously.
A very important fact is that psoriasis is not infectious in nature, which means that it is not transmitted in any way.Given such a variety of reasons why psoriasis appears, any person can be at risk.
It can happen to both an adult and a child, even babies.The earlier psoriasis appears, the more severe it can become throughout life.Therefore, it is very important to take care of your health, eat properly, do not abuse alcohol, protect yourself from skin damage and periodically strengthen the immune system.
