Itching of the skin is a kind of sensation that provokes the need to scratch. This disease refers to cortical processes. Itching occurs due to the action of individual irritants on the nervous system. Thus, this condition is considered a neuro-reflex process.
Itching of the skin is possible under the influence of endogenous and exogenous stimuli, in cases of changes in the functions of the nerve departments (conductor and central).
Acute seizures are often associated with hypersensitivity to drug and food allergens. Itching of the skin in a chronic form in some cases is caused by autointoxication, metabolic disorders in the body.
The condition can accompany many dermatoses, in many cases it refers to the early symptoms of diseases of the hematopoietic system, malignant neoplasms, endocrine disorders, mental and nervous disorders.
Clinically, itching on the skin is divided into localized and generalized. The generalized state, in turn, is divided into senile, seasonal. Senile generalized itching occurs in connection with age-related skin changes or atherosclerotic phenomena. The seasonal state is noted in the autumn and spring periods most often in those suffering from vegetative-vascular dystonia.
Itching is often a symptom of some latent pathological condition, so a thorough examination of the patient is necessary.
A condition of a localized nature is most often noted in the genital area and anus. As practice shows, itching in the anus occurs more in men. The cause of the condition, as a rule, is non-compliance with hygiene rules. It should be noted that in many cases the condition provokes complications in the form of proctitis and other diseases. Itching in the groin area is most often observed in women. The causes of the condition include trichomoniasis, menopause, the irritating effect of urine, candidiasis, inflammation in the genitals, sexual neurosis. Clitoral itching in some cases indicates an early development of cancer in the genitals. It should be noted that in such cases, the diagnosis is made in accordance with laboratory and clinical studies, as well as after a thorough interview of the patient.
Symptoms of skin itching include itching itself, as well as characteristic scratching throughout the body or on limited areas of the cover. As practice shows, the strengthening of the state is noted with the onset of night, and when combing, it passes from one section to another. In many cases, the condition is accompanied by a sensation of burning, crawling, tingling and other things. Very often, against the background of such conditions, "itching paroxysms" develop. In this case, patients, losing their temper, begin to comb the skin before the appearance of bloody wounds.
In many cases, older people have itchy backs. Its appearance is characterized by suddenness, in some cases - by a special intensity. Many people believe that the condition is due to the fact that they did not wash well. However, when you take the bath again, the itch not only does not go away, but also after it there are red dots on the back. In most cases, this is due to a violation of certain body functions. The condition may be the result of an increase in blood sugar, bilirubin, liver disease and other disorders.
It should be noted that a specialist should deal with the identification of the causes of itching. Along with this, attention should be paid to the diet. Experts recommend eliminating products that can cause itching, that is, causing your intolerance.
