There are small white spots on my arm

Spots often appear on everyone's skin, and there are many diseases that can cause white spots to appear on everyone's skin. Many people find that a patch of small white spots suddenly appears on their arms, but they don’t know what causes it. If a patch of small white spots appears on the skin, you need to carefully observe the color of the white spots, determine the condition, and use appropriate medication. So, what is the cause of the small white spots on my arms?

1. What is the cause of a patch of white spots on my arm?

1. Vitiligo: This is the most common white spot; it often appears as porcelain white. Many people don’t understand what porcelain white is. Just think about the white color of the damaged part of a porcelain bowl. Yes, it is the extraordinary white color; it can appear on all parts of the body.

2. Idiopathic leukoplakia: It manifests as small white spots on the back of the hands, arms and legs, which are usually smaller than green beans and can appear in large numbers. It is related to aging and is harmless to the human body.

3. Pityriasis alba: This type of pityriasis alba is often manifested as skin lightening. Remember, it is lightening, not whitening. Most of the time, there are white flakes on the surface. This type is often accompanied by the same lesions in other parts of the face.

4. Birthmarks: There is nothing to say about this. Most of them appear at birth or about three months after birth. They will exist for life.

5. Halo nevus: This is usually manifested as a white spot in the middle surrounded by a white ring; this type is often seen as a precursor to vitiligo, but not necessarily;

6. Anemic nevus: The local color becomes lighter, and the local skin color does not change after friction. It can be identified by Wood's lamp;

2. What fruits are good for vitiligo?

When choosing fruits, patients with vitiligo need to pay attention to eating less or no fruits rich in vitamin C. There are many fruits of this type, such as strawberries, grapes, oranges, watermelons, etc. These will not only not improve the skin, but will also make the skin of vitiligo patients whiter, so patients need to pay attention. You can eat more fruits such as bananas, lychees, etc. This type of fruit is rich in protein and tyrosine, especially bananas, which can accelerate the secretion of melanin in patients with vitiligo and have a certain helpful effect on the treatment of vitiligo. Therefore, patients can eat more of them in normal times.

3. What should not be eaten by vitiligo patients?

1. Since the skin of vitiligo patients is more sensitive, they should eat less spicy and other irritating foods to avoid irritating the patient's skin, damaging the body's own immune function, and aggravating the onset of vitiligo. Try to eat less tobacco, alcohol, and foods containing raw garlic, onions, peppers, lamb, and seafood.

2. Although vitamins are good for the body, for patients with vitiligo, fruits rich in vitamin C are absolutely prohibited. For example, hawthorn, grapefruit, tangerine, orange, tomato, etc. should be eaten less, because vitamin C will affect the synthesis of melanin and affect the treatment effect of vitiligo.

3. Many people think that vegetables are harmless to the body, but spinach contains oxalic acid, which can make the affected area itchy and affect the patient's control of the disease.
