Psoriasis is a chronic dermatological disease that affects more and more people nowadays.Psoriasis is expressed by the appearance of red papules on the skin;it is called "scaly lichen" among the people.The skin is red and itchy, accompanied by a burning sensation.Lesions vary from pinpoint to extensive and generalized.The most common 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 genitalia and internal organs is also detected, but these forms are diagnosed very rarely.Symptoms of psoriasis also include:
- The appearance of cracks on the skin, which causes very unpleasant pain;
- The structure of the nails is disturbed;
- Dry skin, which causes skin cell death and erosion;
- 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 film.
Psoriasis patients often spend more time in aggressive nervous tension, suffer from depression and lower self-confidence.
If psoriasis is not treated in time, symptoms such as fever, damage to the nail surfaces and fractures of the joints may occur, indicating the severity of the disease.In such a situation, qualified medical assistance is simply necessary.
Since this disease is quite popular, everyone should know the main reasons for the appearance of psoriasis.
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 appearance of psoriatic plaques on the skin, other functional disorders in the body are also diagnosed, that is, the activity of the immune, nervous and endocrine systems is disturbed.
The causes and mechanisms of psoriasis have been studied for over a century, but science still lacks a clear 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 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, mistaking them for foreign cells.Can't disagree with that;Undoubtedly, with a decrease in immunity, a skin disease such as psoriasis 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 has psoriasis in the family, then the probability of this disease occurring in children reaches 25%, if both parents are sick, the probability of the disease in children increases to 70-75%.Despite such impressive numbers, official medicine does not consider genetic predisposition to be the main cause of psoriasis.
Neurogenic theory
The main theory most doctors rely on is the neurogenic theory.According to this theory, psoriasis occurs with increased nervous excitability, frequent stressful situations, problems in work and personal life, and developed neurosis.
Neurosis leads to narrowing of blood vessels and weakening of blood flow to the skin, due to which papules are formed.
It was determined that frequent experiences, nervous breakdowns, stress when changing the place of residence, stimulation and 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.But they still haven't found the specific type of virus that causes psoriasis.Of course, after suffering from a viral illness or during an illness, the immune system is weakened and the possibility of psoriasis increases.
This theory of the formation of skin psoriasis raises many questions and doubts in medicine, 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 case of psoriasis.
Key factors
There are a number of factors that can lead to the development of the disease that causes psoriasis:
- Skin injuries;
- Increased nervous excitement, frequent stress;
- Viral and infectious diseases;
- use of antibiotics, vitamin complexes;
- Changes in climate, especially if a drier climate changes to a wetter climate;
- Dermatological diseases: fungal diseases, dermatitis;
- Wrong diet: a lot of sweets, fatty foods, alcoholic products;
- Changes in hormonal levels in women, especially during pregnancy, menopause and breastfeeding.
Psoriasis can occur under the influence of any of the above factors, so people prone to this disease should protect themselves from the influence of these factors.
The main cause of psoriasis is considered to be a complex failure in the human body as a result of the influence of several factors.
A very important fact is that psoriasis is not contagious in nature, that is, it is not transmitted in any way.Considering the various causes of psoriasis, every person can be at risk.
It can happen to adults, children, and even babies.The earlier psoriasis occurs, the more severe it can become throughout life.Therefore, it is very important to take care of your health, eat right, do not abuse alcohol, protect yourself from skin damage and strengthen the immune system from time to time.
