Causes of psoriasis


Many people know about this common and unpleasant diseases, such as psoriasis. The disease is common among men and women of almost all ages. Often diagnosed psoriasis, what is a disease in medical practice, and children. The main symptoms are rashes in the form of rounded or oval spots on various parts of the body. In the advantage of cases of a disease that affects the skin. Most often, the psoriatic plates, which appear on the elbows, knees, palms of the hands, soles of the feet, growth of hair on the head, armpits, groin and skin folds. However, the disease can affect not only the dermis. There are a number of diseases that damage the joints (psoriatic arthritis) and nails (nail psoriasis) and eyes.

Studies in psoriasis have been carried out for a very long time, but to the nature of the disease has not been elucidated. Some experts link the pathology with the work of the human immune system, while others argue that the real causes of pathology is stress and excessive emotional distress, others tend to believe that for the occurrence of diseases due to violation of metabolic processes in the body. The theory of disease, which are great, but none of them have scientific confirmation. Exactly what is known, is psoriasis, the causes of which are now remain a mystery, refers to non-infectious inflammatory disease of a chronic nature.

Theory on the origin of psoriasis

Causes of psoriasis is a very controversial issue today, not giving the rest of the world scientists. Numerous laboratory and clinical studies cannot provide scientific explanations of the development of the disease. All theories are only conjecture. In practice have confirmed, to some extent. Therefore, the following article will attempt to find an explanation for the development of these diseases, such as psoriasis from a scientific point of view. Causes of psoriasis, to date, explain the following theories:

  1. Immune.
  2. Hereditary.
  3. Endocrine.
  4. Virus.
  5. Neurogenic.
  6. Exchange.

All were developed on the basis of the etiology and pathogenesis of the disease is the result of years of research, of psoriasis.

The immune theory

the immune theory

Scientists believe that the cause of the disease, which is directly connected with the immune defense of the person. This theory is one of the most common and reliable on the day. Representatives of this view argue that psoriasis occurs under the influence of such things as autoimmune aggression. This process is the result of the sensing by cells of the immune system on the cells of the dermis as the aggressors. This is perceived as foreign bodies. the result of such reaction particles of skin, which is severe inflammation and refused. The rejection process usually begins in the following cases:

  • frequent friction of the skin;
  • burn;
  • abrasions, scratches and other damage to the skin.

Study of psoriatic scales with biopsy allowed to detect in them some of the antigenic spaces while in the blood is a large number of antibodies to them. Partly this confirms the linkage of disease with immunity, but it turns out in the full theory, in practice it is not yet possible. It is believed that the disruption of natural protection a person can speak only one of the trigger factors of psoriasis.

Theory of heredity

On the occurrence of psoriasis also explains the theory linking it to genetic predisposition. Supporters of this view say, that is the main reason for a disease that is hereditary factor. Simply put, a disease that is passed on from relative to relative through the bloodstream.

Research in this area has shown that the cause for psoriasis may be genetic predisposition, as more than 60% of all patients who have family relatives who are also suffering from the disease. In addition found the following:

  • if psoriasis is a sick one of the parents is probability of disease in the child may be 25%;
  • in this case, when the rash occasionally suffer from both parents, the risk increases by more than half and 75%.

Genetic theory to date, though, and has some confirmation in practice, it is of fundamental importance. In many cases the complaints of patients to help in addition to heredity it should be noted, the combination of many other factors that cause the disease.


the endocrine theory

This theory suggests that the causes of psoriasis can go into the hormonal imbalance in the body. Having carefully studied the pathology, scientists have believed that the pathophysiology of the rapid process of cell division, the dermis of the person, when the disease, which is associated with hormonal imbalance. Most often such errors occur because of a variety of diseases of the endocrine system. This can be the pathology of the thyroid, pancreas and pituitary gland. Also possible reasons hormonal failure can be the following of the human condition:

  • pregnancy;
  • ovulation;
  • taking certain hormonal drugs.

In practice, the doctors found it to be a significant aggravation of disease in this period. However, despite this relationship and the alleged confirmation of the theory in practice, basic and proven, I don't think.


Causes of psoriasis for a long time, associated with the transmission of diseases viral nature, as well as with the presence of foci of chronic inflammation in the body. This theory is based on facts, that it was during the disease is caused by a virus, psoriasis significant acute. There are also cases, the initial onset of psoriasis between the diseases of viral etiology. Rejects the theory that, as a result of this disease significantly weakens the human immune system, which can also be associated with the development of psoriasis. In addition, it is a known fact that psoriasis is not transmitted from person to person, so this theory does not have confirmation from a medical point of view.



Representatives of this view claim that it is psoriasis often occurs in the nervous system. Neurogenic theory postulates the causes of psoriasis is directly related to the psychosomatic state of the person. This view is one of the most young and not proven in practice. Explains the theory of the development of the disease the presence of the following human conditions:

  • stress;
  • excessive worry and worry;
  • sleep disorders;
  • only exhaustion.

As a result of such violations of a person observed in the neurosis of the blood vessels, causing their constriction and as a result, the flow of blood in the tissues of the dermis. Such a failure allows the development of the body psoriatic lesions of different nature.

According to the statistical data collected in the twentieth century, a larger percentage of people with some form of pathology, the forerunner of the disease was stress.

The theory of exchange

Causes of psoriasis and its treatment is today a very current topic. What appears psoriasis? This question haunts not only patients but also doctors. The theory of metabolic abnormalities associated with the development of the pathology with violation of the metabolic functions in the body. During long-term studies of the disease, and many laboratory tests have identified some characteristics that connects all of the patients. The data obtained give reason to believe that the cause of psoriasis lies in the disruption of metabolic processes. So, what is the total of:

  1. Infringement of metabolic processes, which indicates the body temperature of patients below normal.
  2. In the body of patients show increased levels of cholesterol and other negative substances that in a healthy person are shown in a natural way.
  3. An imbalance of vitamins. In all patients, the pathology of the b vitamins and the deficiencies. However, vitamin C, on the contrary, in excess.

The exchange theory, though, and has some confirmation in practice, it is not officially confirmed.

Factors that cause the disease

In short, to highlight a number of factors, which may not only cause disease, but much worse. So, what triggers psoriasis, we will see next.

Spiritual causes of psoriasis

Often the appearance of psoriasis associated with stress and anxiety. If you want to exclude complications, doctors recommend limiting yourself from excessive fatigue, strong nervous tension and situations that may cause stress.

Diseases of the infectious nature of the


To elicit the basic progression of the disease and its complications, which may be chronic inflammatory disease. To avoid such unpleasant consequences, so it is recommended to timely treat the infection, do not start the disease, when medical attention.


Causes of psoriasis in women is often associated with pregnancy. It was in this period, the body observed a strong hormonal changes. Any pregnant woman who suffer from the disease, are obliged to pay careful attention to their health. Preventive measures include timely prenatal visits, avoidance of stressful situations, proper diet, avoiding harmful habits, respect for the day.

Injury and damage to the skin

The causes of disease often lie in the chemical mechanical injury to the dermis. A variety of burns, injuries, scratches and other minor damage, which can become the factor that caused the disease. Also the disease can develop due to the effect on the skin chemicals. For example, various detergents. People who deal with such materials, doctors recommend to wear protective equipment.

Bad habits


It also proved a significant negative impact of bad habits on the course of the disease. The use of alcoholic beverages, cigarettes and other drugs, and is aggravated by psoriasis. This is explained in the relationship effects of bad habits on the immune system of the patient.

Use of certain medications

Medication can bring not only benefits but also harm. In psoriasis, the use of these drugs, as some types of antibiotics, Immunostimulants, vitamin can cause a malfunction of the immune system. The result is a complication of the disease.

Improper diet

Man's daily diet can also lead to the development of pathology and its many complications. Patients who suffer from disease or have a predisposition to the disease is very important to monitor their diet. From dishes it is recommended to be greasy, spicy, fried, smoked is too salty dishes. Nutritionists recommend to give priority to the food that is being cooked and the cooking method. The table should be a sufficient amount of fruits and vegetables, milk and milk products.

So that the causes of psoriasis are very different. To provoke disease that can affect many factors. But do not think that psoriasis is a sentence. Timely treatment, responsible attitude to the body, the adjustment of the mode of day and feed, will allow to cope with the disease and to avoid complications in the future.
