What are the white spots on my legs?

In our lives, many people suffer from some skin diseases. Most patients have skin diseases because they often do not exercise and have low physical fitness. Some people will grow some small white dots on their skin. At this time, they will be more scared because the small white dots are likely to be vitiligo, and vitiligo is a skin disease that is particularly difficult to treat. So what are the small white spots on the legs?

There are many reasons for the growth of small white spots on the legs. Excessive light, lack of trace elements and traumatic stimulation may all cause small white spots on the legs. Symptoms of pigment diseases such as tinea versicolor and anemic nevus can also cause small white spots to appear. Therefore, if patients find small white spots, they should not take it lightly. They should go to a regular hospital for diagnosis and examination in time to avoid delaying treatment.

1. Excessive light. When the skin is exposed to light, the melanocytes and melanin synthesis process become relatively active, so light can make people darker. However, after receiving excessive light, ultraviolet rays are likely to cause melanocyte hyperactivity and compensatory proliferation. The end result is that melanocytes quickly die, melanin synthesis is interrupted, and small white spots appear.

2. Traumatic stimulation. Some external traumatic stimuli, such as burns, frostbite, surgical wounds, etc., are the causes of small white spots on the patients' hands. Moreover, the appearance of these small white spots often means that the patient has suffered from vitiligo. This should be taken seriously. If it can be discovered and treated early, the possibility of cure is still very high.

3. Lack of trace elements. Trace elements are active substances that participate in the intermediate links of the body's metabolism, such as copper, zinc, selenium, iodine, etc. They are directly involved in the synthesis of melanocytes and also protect melanocytes from damage by heavy metal poisons. Trace element deficiency and imbalance can lead to melanocyte synthesis disorders. The white spots on the calves may be symptoms of vitiligo. The specific symptoms of vitiligo are as follows:

4. The white spots of vitiligo patients can appear on various parts of the human body such as the skin, oral cavity, and external genital mucosa. They vary in shape and size and appear as single or multiple irregular depigmented spots. The area of ​​leukoplakia gradually increases and the number increases as the disease progresses. Although all vitiligo patients show white patches, the color of the white spots varies due to different degrees of pigment loss, appearing as light white, milky white, cloud white and porcelain white. In a small number of patients, the white spots will disappear on their own.

5. Vitiligo is more sensitive to sunlight or ultraviolet rays. If you are a vitiligo patient, the white spots may turn red after sun exposure, and there may be burning and itching sensations. Therefore, patients with vitiligo should avoid direct sunlight and exposure to the sun and try to take preventive measures.

6. In general, there is a clear boundary between white spots and normal skin. In the early stages of vitiligo, the boundary is clear and the surface is smooth. However, during the development stage of vitiligo, the boundary between the white spots and normal skin is blurred, the surface is smooth, and there is no desquamation or scab. The hair of white spots can be white, black, or a mixture of black and white. A few patients experience severe itching, and some patients have white spots

The sweat secreted from the vagina has an odor. The symptoms of vitiligo are small white spots, but the appearance of small white spots does not necessarily mean it is vitiligo. Patients should be careful to distinguish and identify them. Many people say that the causes of vitiligo are complex and difficult to treat. In fact, as long as patients can grasp the key to treating vitiligo, go to a regular professional vitiligo hospital for a scientific and comprehensive examination in time, identify the causative factors, and treat the symptoms, vitiligo can be cured.
