Generally speaking, during pregnancy, due to reduced immunity, hormonal changes, or deficiencies in vitamins and trace elements, vitiligo can spread and worsen. Using oral and topical medications during this period is troublesome, and pregnant women are generally advised against taking medications. It is advisable to visit the dermatology department of a regular hospital for localized 308 laser treatment, which does not affect pregnant women. It is essential to seek treatment at a reputable medical institution where a doctor can diagnose and provide a treatment plan. During pregnancy, it is recommended to consume more black-colored foods such as black rice, black beans, black sesame, wood ear mushrooms, and mushrooms, while avoiding consuming too much vitamin C-rich food like strawberries, oranges, tomatoes, pineapples, and mangoes.

The causes of vitiligo

The main causes of vitiligo are related to decreased immunity, hereditary factors, or a deficiency in copper within the body. Additionally, local injuries in some individuals may also lead to the development of vitiligo. The causes are complex and may vary from person to person. Once diagnosed, it is essential to seek treatment at a reputable hospital; otherwise, the condition may worsen, expanding the affected area and making treatment more difficult. It is advisable to avoid spicy and irritating foods, not to stay up late, to exercise regularly, and to enhance immunity, which can also be beneficial in treating this disease. Generally, it is good to eat foods that are rich in black pigmentation and to avoid consuming too much food rich in vitamin C, as well as to prevent local injuries.

Can people with vitiligo eat lychees?

People with vitiligo can indeed eat lychees. Lychees have benefits such as stimulating the appetite, nourishing the blood, dispersing clumps, regulating qi, and relieving pain. Concerns about eating lychees mainly arise from their vitamin C content. It has been suggested that prolonged consumption of vitamin C supplements, such as taking more than 1-3 grams daily for several months, may potentially trigger vitiligo. However, normally consuming moderate amounts of vitamin C-rich foods or fruits does not significantly affect vitiligo. Moreover, it is now believed that reactive oxygen species within the body are one of the factors contributing to the development of vitiligo, and vitamin C, as an antioxidant, can help clear these reactive oxygen species from the body and protect melanocytes. From this perspective, eating vitamin C-rich foods normally does not have any adverse effect on vitiligo.

What are the advantages of epidermal grafting for vitiligo?

Epidermal grafting is suitable for vitiligo in its stable phase, where patches on the body have not changed for at least six months and have not improved with treatment. At this stage, one can opt for epidermal grafting, which involves relatively minor trauma and is not too costly. The local growth of melanin is rapid, and the results tend to be favorable for patients in the stable phase. During the treatment period, it's essential to avoid spicy and irritating foods, consume more black-colored foods, avoid excessive intake of vitamin C-rich foods, enhance physical exercise to boost immunity, and keep the treated area dry and free from friction to prevent melanin loss.

The term "progressive stage of vitiligo" refers to a phase in which the skin condition vitiligo is actively spreading, with new patches forming and existing patches expanding.

The progression phase of vitiligo, also known as its development phase, is characterized by the enlarging and whitening of the skin patches. This phase primarily signifies that the patches are expanding and becoming more pronounced in color. Vitiligo is related to factors such as reduced immunity, genetic heritage, copper deficiency in the body, or local injuries. Through proper treatment, the progression phase can gradually shift into a recovery phase, where melanin increasingly covers the white patches. Some patients may enter a stationary phase where neither medication nor lack of treatment changes the condition of the vitiligo; typically, if there’s no change for over a year, it enters this stationary phase. If it is determined that the vitiligo is in the progression phase, prompt treatment is crucial to prevent the condition from worsening, which could make treatment more difficult.

Will vitiligo recur after skin grafting?

Vitiligo generally enters a stable phase after which skin grafting is quite effective. The stable phase is typically reached when, after about a year of treatment, there are basically no changes, no worsening or improvement in the condition, which is referred to as the stable phase. Using the method of skin grafting to directly implant melanocytes into the depigmented regions tends to be effective. Generally, after skin grafting, melanin quickly proliferates and extensively covers the depigmented areas. However, the factors causing this disease are quite complex. Some individuals, especially those with lower immunity, might experience recurrence even after a successful graft. Therefore, personal health status and clinical evidence should be considered individually.
