White patches and vitiligo have clear distinctions.

White patches primarily refer to localized hypopigmentation on the skin, a type of macule where pigment loss occurs due to a reduction in function or number of melanocytes. White patches can appear on the skin due to various reasons or diseases, including post-inflammatory hypopigmentation, tinea versicolor, and pityriasis alba.

Vitiligo, on the other hand, usually refers to a specific skin condition. The causes of vitiligo are multiple and can be related to psychological factors, autoimmune dysfunction, leading to the destruction and reduction in melanocytes. The appearance of white patches in localized skin areas is called vitiligo, and its typical lesion is also a localized white patch, which is a type of white patch.

Therefore, diseases causing white patches could potentially include vitiligo or other conditions. Vitiligo is just one possible cause of white patches.

What should I do about vitiligo?

Vitiligo belongs to a category of pigmentary disorders, which can affect social interactions and psychological well-being to some extent, but does not affect health and growth. Therefore, it is necessary to approach this condition with scientific rationality. First, it is important to prevent skin trauma, rest adequately, stabilize the body's immune status, and manage sun protection. Symptomatic treatment includes oral administration of drugs such as compound glycyrrhizin tablets and folic acid tablets. Tacrolimus ointment should be applied externally to the lesions. Treatment can also be supplemented with traditional Chinese medicine, including Bai Ling tablets and Qu Bai Ba Bu Qi tablets, although liver and kidney functions must be monitored. Additionally, therapy may include 308 nm excimer laser irradiation, two to three times a week, for a total of 10 to 14 sessions per treatment course.

Can late-stage vitiligo be life-threatening?

Generally speaking clinically, vitiligo does not have a concept of a late stage, but if the disease has been present for a long time and covers a large area, treatment can be troublesome. Vitiligo poses no harm to life and health; even if the affected area is large, it does not threaten life, but treatment can be troublesome, requiring long-term commitment and substantial costs. Once detected, it is best to seek formal treatment at a dermatology department of a standard hospital. Generally, doctors will formulate a treatment plan based on the individual's condition. The combination of oral medication, topical medication, and 308 laser therapy is currently the most effective method for treating vitiligo. During the treatment period, it is also important to strengthen physical exercise to enhance immunity, helping to prevent the complete loss of melanin after it is deposited.

Why do babies get vitiligo?

There are many factors contributing to the formation of vitiligo, and the most common factors related to its onset include reduced immunity, genetic heredity, copper deficiency in the body, or localized trauma, but the specific cause of the disease is difficult to determine and is currently an international challenge. The appearance of vitiligo in children may be related to a copper deficiency or low immunity. It is advisable to visit a dermatologist at a formal hospital to determine the appropriate treatment. The most conventional treatment generally includes oral medications and topical drugs, combined with 308 laser therapy. It is also advisable to get moderate sun exposure, consume more black-colored foods, and avoid excessive intake of vitamin C-rich foods. Additionally, children should engage in appropriate exercise to enhance their immunity.

Can people with vitiligo eat peaches?

People with vitiligo can eat peaches. Peaches are rich in vitamins and also contain a substantial amount of iron. In traditional Chinese medicine, peaches are said to nourish yin, generate fluids, moisturize the intestines, and facilitate bowel movements. They are considered a good fruit symbolizing fortune, prosperity, and longevity. Although long-term excessive intake of vitamin C is one of the triggers for vitiligo, vitamin C also acts as an antioxidant. It helps the body eliminate free radicals, which, when in excess, can damage our body's melanocytes. Therefore, appropriately consuming fruits that contain vitamin C, such as peaches, does not affect vitiligo.

Is a white patch on the face vitiligo?

White patches on the face are common, with the most typical being pityriasis alba or pityriasis versicolor. These conditions are generally related to a lack of vitamins, trace elements, or fungal infections on the skin's surface. These types of patches are usually vague, with unclear boundaries and may also have some fine scales on them. The second type of white patch is vitiligo, which is usually much whiter. When examined under a Wood's lamp, they appear bright white and have irregular edges, with a tendency for the patches to expand over time. Another type of white patch is the nevus depigmentosus, which is congenital and present from birth. These patches generally do not expand and are not particularly white. If there is any uncertainty, it is best to consult a dermatologist at a reputable hospital and have it confirmed with a Wood’s lamp or a dermatoscope.
