Vitiligo is a pigmented skin disorder caused by impaired melanocyte function, which is simply a loss of melanin in the skin.

The pathogenesis of vitiligo is very complex, specifically can cause vitiligo are mainly the following reasons:

1, autoimmune dysfunction. Individuals with low autoimmunity have an increased likelihood of developing vitiligo.

2, melanocyte function is damaged. The main function of melanocytes is to form melanin, once the function is impaired, melanin formation will be reduced or stopped, it will cause vitiligo.

3, genetic factors. Vitiligo has the possibility of heredity, it is worth noting that the probability of heredity is not 100 percent.

4, microcirculation disorder. Related research that, like pants belt tight waist and abdomen and other parts of the skin prone to vitiligo, the main reason is the pressure parts of the microcirculation disorder.

5, the lack of trace elements. Copper, zinc, calcium, magnesium and other trace element deficiencies may also induce vitiligo.

6, chemical substance stimulation. For example, long-term exposure to phenolic compound products like plastic and rubber may induce vitiligo.

7, strong ultraviolet exposure. Skin blisters may appear after exposure to sunlight, and some patients will develop vitiligo after the blisters subside and local skin pigmentation is lost.

8, mechanical friction and trauma. Long-term pressure, friction areas, as well as skin trauma, are vitiligo susceptible areas.

9, long-term psychological pressure. Mental stimulation, excessive brain use is a common cause of vitiligo, even in the first place among many causes.

According to clinical evidence, with the increase of vitiligo treatment means, many patients have achieved better results.

In the initial stage of vitiligo, the treatment is relatively easy. For patients with vitiligo in the developmental or stabilized stage, there are treatments such as pills, smears, phototherapy, epidermal transplants, etc. However, it is still necessary to go to a regular hospital to look at the patient's specific condition to develop a treatment plan.

　　Vitiligo affects people's normal life, the symptoms of vitiligo is mainly in the form of white spots, the number of white spots is not certain, can rarely change or fade away, but most cases show that the white spots gradually increase, expand, adjacent white spots fused into irregular large pieces, and even flooded the whole body. Vitiligo patients in each of the onset of the different performance, the following we come to understand the specific details of it.

　　1, latent period: vitiligo development process is relatively slow, the first period of vitiligo, this time vitiligo disease has a latent period, latent time has half a year or decades, in the latent process, the disease position basically did not to the serious development in a longer period of time the development of the disease did not change significantly, patients generally have no obvious self-conscious symptoms.

　　2, stationary period: the onset of the area is no longer to the serious development, and a small number of light patients with the phenomenon of self-healing, mainly because of changes in the work environment or the factors of the enhancement of their own immunity. This is the early clinical manifestation of vitiligo.

　　3, the initial period: vitiligo first point-like type onset, the development is very slow, in 1-3 months without obvious disease development, the onset of the site of light pigmentation.

　　4、Progressive stage: the disease is a continuous process of development, in 1-3 months the disease develops rapidly, about the disease position develops to 1-3 times, there are a few people can infringe on the skin more than 50%, the onset of the site is irregular, the edge of the unclear, irregular, the symptoms will slowly become serious.

　　The clinical manifestations of vitiligo are easy to spread, so it is necessary to receive treatment at an early stage. Only if we have enough knowledge about the manifestations of vitiligo, we can predict the occurrence of vitiligo, and then we can actively treat vitiligo, in addition to the treatment at the same time planning I we also need to actively prevent.

Vitiligo is caused by a lack of melanin to form white patches, and there are many causes of vitiligo.

1. TraumaThe skin has a series of traumatic injuries such as burns, frostbite, etc., resulting in damage to the cells at the wound, which in turn leads to dysfunction of the neuroendocrine system in the body, greatly reducing melanin synthesis and metabolism, which can lead to the emergence of vitiligo.

2. Dietary problemsDisease enters by the mouth" is a very reasonable saying, in addition to other diseases, often eat rich in vitamin C, stimulating and hair products will irritate the skin, will increase the occurrence of vitiligo.

Vitiligo is a stubborn chronic disease that will spread easily if not treated in time. The condition if delayed for too long, the patient's physical and mental health hazards more and more, the treatment difficulty will be more and more difficult. Therefore, patients must be timely diagnosis and treatment, reasonable improvement of protection and conditioning methods. There are a lot of factors that induce vitiligo, different conditions, individual differences, treatment methods are also different, it is recommended that the patient to the regular hospital comprehensive system to be examined clearly, to find out the cause of the disease and then symptomatic treatment, in order to achieve the desired therapeutic effect.

The causes of vitiligo are complex, such as stress, trauma, decreased immunity, endocrine disorders, tyrosine. Copper ion relative lack, heredity, infection and so on. Often a simple causative factor is difficult to trigger vitiligo, the general onset of the disease is mostly caused by the combined effect of several causative factors.

In addition, vitiligo patients should pay attention to not eat spicy food and avoid staying up all night!
