What is the cause of exogenous leukoplakia

Essential**. Autoimmune disorders.

Non-segmental vitiligo is considered an autoimmune disease. In autoimmune diseases, the immune system is disordered, and actions that attack healthy cells and tissues in the body occur instead of being responsible for attacking foreign pathogens like the normal immune system. Patients with non-segmental vitiligo produce antibodies to their own melanocytes mainly due to a disorder of the immune system, which in turn leads to a decrease in melanin production.

Vitiligo can also be complicated by other autoimmune diseases, such as thyroid disease (such as hyperthyroidism), autoimmune polyglandular syndrome, etc., but not all patients with vitiligo will develop these diseases.

Genetic factors. Some patients have familial clustering, which belongs to the category of polygenic diseases.

Neurochemicals.

Segmental vitiligo is thought to be caused by biochemicals released from nerve endings. These substances have a destructive effect on melanocytes, resulting in a decrease in melanin production.

Predisposing factors. Vitiligo can be triggered by a variety of factors:

1. Vitiligo is mostly considered to be caused by autoimmune factors, melanin self-destructive factors, and neurochemical factors.

2. Autoimmune factors: When the patient's body immunity is relatively low, the body cells in the body may produce some of their own melanocyte antibodies, which will lead to a decrease in melanin production and cause vitiligo.

3. Melanin self-destructive factors: if the epidermal melanocytes of the patient's body are hyperfunctional, it will lead to melanin depletion or gradual decline, resulting in vitiligo.

4. Neurochemical factors: If the patient has mental trauma, overwork or excessive anxiety, it may lead to an increase in neurochemicals around the cells of melanin, which inhibits the formation of melanin and causes vitiligo.

5. If there is vitiligo, it is recommended to go to the hospital for a clear diagnosis.

There are many causes of vitiligo, such as: genetics, abnormal immune function, susceptibility to colds and fatigue, etc.; Endocrine and metabolic disorders, melanocyte self-destructive factors, mental stress, high pressure in life and work; There are many reasons for abnormal regulation of the nervous system, trauma, surgery, exposure to chemicals, sun exposure, etc.

There are many predisposing factors for vitiligo, such as chemical, physical, genetic, etc., any part of the body will be affected, and the incidence of exposed parts is high.

1. Industrial pollution, agricultural pollution, endocrine and immune dysfunction, trace element deficiency, and genetic factors.

There are physical, chemical, biological, mental, genetic, etc.

There are many reasons for this, which are generally related to mental, chemical, physical, biological, and genetic factors.

There are many reasons, such as trauma, sun exposure, genetics, excessive mental stress, environmental pollution, and many other aspects.

There are many reasons for inducing, and each person's reasons are different, but the main thing is to increase melanin, and to deal with various situations, it all boils down to one method, which is to keep the generated melanin from being destroyed.
