What is the exact pathogenesis of vitiligo?

Lesions occur on the trunk and upper extremities, with pale white round or oval plaques with ill borders and fine scales on the surface, and a positive fungal examination.

There are many types of vitiligo, and there are many types of vitiligo, different types, different genres, and different properties use different methods. Vitiligo must first be diagnosed, then formulated, and then carried out. Different conditions, ** methods are also different, first of all, it is recommended that patients do not blindly**, so as not to aggravate the condition.

No matter what the disease, it is necessary to find the missing hormone first and carry out it in a targeted manner.

Click to test how your vitiligo is caused.

The ** that causes vitiligo is currently unknown and may be related to the following factors:

1.Genetic factors: two or even three people in a family may develop vitiligo;

2.Melanocyte self-destruction: Some studies have found that autoantibodies against melanocytes can be detected in patients, and this antibody has a certain destructive effect on melanocytes, resulting in the loss of melanocytes and the appearance of white spots;

3.Other factors, such as trauma and stress, can also be triggered.

Vitiligo is a primary, localized, or generalized** depigmentation. It is caused by local pigment disorders, and the decreased function of the tyrosinase system in melanocytes of hair follicles, which makes the epidermis obviously lack melanocytes, resulting in depigmentation. Although vitiligo does not affect the health of the patient, it is also a bitter symptom, but because it often occurs on the face and other exposed parts, it affects the appearance, affects the appearance, and makes the patient often feel distressed.

In severe cases, it can spread throughout the whole body, which will affect the physical and mental health of patients to a certain extent.

(1) Vitiligo caused by unreasonable diet

If we don't pay attention to our diet in life, it is easy to cause some diseases in the upper body, among which vitiligo is one of them. For example, many young people often go out to drink, get drunk and unconscious, and eat spicy strips and seafood can cause vitiligo patients to expand and aggravate the condition. There are also some foods that contain phenols, which also affect melanocytes.

2) Inflammation of the body causes vitiligo:

Vitiligo is very harmful, what causes vitiligo? If there is inflammation in the body, especially ** inflammation, and relevant nursing measures are not taken, it is easy to cause vitiligo. The first is because of the many substances released in the inflammatory response, which can harm melanocytes.

Patients can improve the body's immunity through physical exercise, prevent the onset of inflammation in the body, and have an excellent effect on preventing vitiligo. When there is inflammation in the body, it is especially necessary to pay attention to the cleaning and care of the body, and you should also eliminate your own inflammation as soon as possible.

3) Causes caused by the external environment:

With the destruction of the living environment and the pressure of daily life, the chance of vitiligo is also increasing, so friends should pay attention to prevent the occurrence of vitiligo due to external factors. With the arrival of summer, it is important to pay attention to sun protection, and it is very important to prevent exposure to the sun, whether it is about the prevention or treatment of vitiligo.

The occurrence of vitiligo can be caused by a reasonable diet, the destruction of melanocytes themselves, the lack of trace elements, the lack of formal treatment of trauma, the infection of wounds and mental disorders, etc., and cause a normal white white pigment symptoms due to the loss of melanocytes in the normal human body.

1. Characteristics of vitiligo in the development stage.

When vitiligo enters the development stage, the patient's own white spots will gradually begin to enlarge, and some adjacent white spots will begin to merge into a large area, and even some ** parts may have new white spots. However, due to the spread of the disease, the patient's own white patches may gradually become more blurry, and at the same time, the patient may also feel a slight itching sensation in the white patches. In this regard, if the above conditions are found, the patient should pay more attention, which is likely to be a sign that vitiligo is about to spread.

2. Changes in physical functions during the development period.

Patients in the developing stage may have some subtle changes in their own body, at this time, due to the influence of the lesion, the patient's own endocrine and immune conditioning ability may be disordered, and because the lesion will begin to develop, the melanocyte function in the patient will be further lost. In addition, some patients with weak constitution may have some trace element deficiencies, and the effects of these aspects may quickly aggravate the development of vitiligo.

1. Early manifestations of vitiligo: white patches are milky white or white. The shape is nearly round, oval, or irregular. Some margins are wound with bands of pigment. Some new leukoplakia has a slightly arched inflammatory dark red strip on the margin.

2. Manifestations of vitiligo in the middle stage: vitiligo patients in the middle stage of the disease, the surrounding cities of the disease site appear, a depigmented ring, its color is slightly darker than the white spots, lighter than the normal skin color, the dispersion ring is intact ring, the white spots on the edge of the dispersed ring are striped, and the surrounding skin is scattered in the shape of rays.

3. Manifestations of advanced vitiligo: The white spots on patients with advanced vitiligo are usually in the shape of a map. The white patches have ceased to develop, the number and area have ceased to increase, and the color of the white patches has gradually deepened, and the boundary with the surrounding skin has become clear, making it easy to identify.

The white spots appear porcelain-white in color, and the melanocytes are simply lost.

1. In the early stage of vitiligo, the manifestations are not particularly obvious. Because the white spots of vitiligo are relatively light in color and light white, mainly because the loss of melanin in the first is not very serious, so the white spots will not be obvious, but the early stage is the best time, and patients should pay attention to grasp this time period in time.

2. Entering the development stage, the disease will continue to worsen. The area of vitiligo will also increase, mainly because the loss of melanin in ** is becoming more and more serious, which will lead to the fusion of small areas of vitiligo to form a large area of vitiligo, in this period of the development of vitiligo, vitiligo will enter the progressive stage, in this period, vitiligo is larger, so ** can not be ignored.

3. Vitiligo leukoplakia will reach a stable period, and the vitiligo leukoplakia will no longer change during this period. The vitiligo will not increase, the area of vitiligo will not increase, and the melanin will stop loss, and the vitiligo will not change for half a year before it can be regarded as a stable period.

At the beginning of vitiligo, the color of the white spots is lighter, the area is smaller, the white spots are mostly milky white or cloud white, and with the development of the disease, it will evolve into porcelain white, and then it is more difficult. The shape of the vitiligo, sometimes porcelain white mung bean to the size of a nail or a coin, the shape is irregular, or round, or oval, the edge of the vitiligo is darker, often surrounded by a pigmentation band, and the normal ** clear demarcation, it is best to go to the hospital for diagnosis, can be detected by slides and wood lamps, and vitiligo is earlier **the easier **, we must actively cooperate with the doctor**, usually maintain a good attitude and good living habits, **vitiligo can be done early**, can be early**.

In the early stage of vitiligo, the skin lesions are depigmented and form white spots or plaques, which are generally round, oval, or irregularly shaped; The plaques vary in size and have a smooth surface. White patches are usually not painful or itchy, but they are sensitive to sunlight, which means redness after sun exposure**, and erythema, blisters and burning sensations will appear after sun exposure. At the same time, vitiligo has a homomorphic reaction, that is, after inflammation or trauma, white spots will begin to appear locally or make white spots expand.

Vitiligo is a hyperpigmentary disease caused by autoimmune dysfunction, which is mainly manifested by hypopigmentation caused by various reasons to form white spots on the body.

At present, it is understood by the medical community that it is a multi-factor ** abnormal pigmentation, and the specific and direct cause is not clear, but it is related to many triggers, such as autoimmune dysfunction, genetics, diet, thyroid dysfunction, trauma, etc.

I hope my answer will be helpful to you: Hello, there are many causes of vitiligo, trauma is one of them, trauma will cause damage to melanocytes and autonomic nerve structure, resulting in melanin synthesis disorders, resulting in vitiligo, **There are thousands of drugs for this disease, but each drug has certain indications, the medication is not right, it is easy to cause the spread of vitiligo, and the condition is aggravated. Good luck soon**!

Hello, glad to answer for you.

Vitiligo is mainly the loss of melanin, and there are dozens of triggers, such as stress, emergency situations, trauma, decreased immunity, endocrine disorders, tyrosine, relative lack of copper ions, heredity, infection, post, etc., there are dozens of triggers, so **don't be blind**, to find out where the root of the disease is**.

Usually, don't have too much psychological pressure.

Mental anxiety, nervousness, unpleasant life events, etc. can trigger this disease, so it is recommended that patients usually do an appropriate amount of exercise to reduce mental stress, relieve tension, and maintain an optimistic, positive, and relaxed attitude. This is very good for relieving the disease.

You can also provide me with a detailed medical condition for targeted guidance**, I wish you soon**!
