Vitiligo

Investigating the Causes, Symptoms, and Treatment of Vitiligo

Vitiligo, also known as leukoderma, is a chronic skin disorder that affects pigment-producing cells (melanocytes). It’s important to clarify that vitiligo is not leprosy. While it can cause changes in skin appearance, it’s not contagious.

Vitiligo can understandably affect a person’s self-esteem and cause anxiety. It’s natural to have questions and concerns when diagnosed with this condition. This article aims to address those concerns by exploring the causes, symptoms, and treatment options for vitiligo.

How Does Vitiligo Develop and What Are Its Symptoms?

Our skin gets its color from pigment cells called melanocytes. These cells produce melanin, which determines the color of our skin and hair. In vitiligo, the body’s immune system mistakenly attacks and destroys melanocytes. This loss of pigment causes white patches to form on the skin, known as macules.

Symptoms of Vitiligo:

• White patches (macules): These are the most noticeable symptom, appearing on various body parts, often starting on hands, forearms, feet, and face.
• Hair color changes: Hair growing in the affected areas may turn white or silver.
• Itching: Some people experience itching before white patches appear.

Who Gets Vitiligo?

Vitiligo can affect people of any age, but it often appears before age 30. Here are some factors that may increase the risk:

• Family history: Having a close family member with vitiligo increases your chances of developing it.
• Skin color: People with darker skin tones may show vitiligo more noticeably due to the contrast between pigmented and non-pigmented areas.
• Autoimmune diseases: Certain autoimmune diseases, like those listed below, can be associated with vitiligo:
  • Addison’s disease
  • Pernicious anemia
  • Type 1 diabetes
  • Lupus
  • Psoriasis
  • Rheumatoid arthritis
  • Thyroid disease

Additional points:

• Vitiligo is not contagious.
• While the exact cause is unknown, several factors may increase the risk, which we’ll discuss in the next section.

Types of Vitiligo

There are several types of vitiligo, each with slightly different characteristics:

1. Generalized vitiligo: This is the most common type, causing white patches to appear on various body parts, often symmetrically.
2. Segmental vitiligo: In this type, white patches appear on one side or a specific area of the body, such as the face or an arm.
3. Mucosal vitiligo: This type affects the mucous membranes, which are moist tissues lining certain body parts like the mouth and genitals.
4. Focal vitiligo: This is a less common type characterized by a few small, localized white patches on the skin.
5. Trichome vitiligo: This rare type features a white spot surrounded by a band of lighter pigment and then a band of normal skin color.
6. Universal vitiligo: This is also rare and involves widespread pigment loss, affecting over 80% of the body’s surface.

Vitiligo Treatment Methods

While vitiligo isn’t life-threatening, there are treatment options available to manage the condition and even regain some pigment. It’s important to note that no single treatment works for everyone, and a doctor will recommend the most suitable approach based on your specific case. Here are some common methods:

• Ultraviolet B (UVB) light therapy: This treatment exposes affected skin to controlled doses of UVB rays to stimulate pigment production.
• Depigmentation: This method is considered when a large area of the body is affected. It involves using medications to lighten the remaining pigmented areas, creating a more even skin tone.
• Topical corticosteroids: These steroid creams can help suppress the immune system’s response and potentially slow the spread of white patches, or even promote some pigment regrowth.
• Calcipotriol: This ointment, a form of vitamin D, is sometimes combined with corticosteroids or light therapy for better results.
• Medical tattooing: This cosmetic procedure involves implanting pigment into the skin with specialized needles.
• Skin grafting: In this surgical procedure, healthy skin with pigment is taken from another area of the body and transplanted to the vitiligo-affected areas.
• Psoralen with ultraviolet A (UVA) light therapy (PUVA): Psoralen is a medication that increases skin sensitivity to UVA light. When combined with UVA light therapy, it can promote pigment production.
• Medications: Certain medications may be used to treat small vitiligo patches.
• Dietary changes: While no specific diet cures vitiligo, some believe certain foods rich in antioxidants and vitamins may be beneficial. However, it’s crucial to consult a doctor before making any significant dietary changes.

Dietary Considerations for People with Vitiligo

While diet alone cannot treat vitiligo, some people incorporate certain foods believed to be rich in antioxidants and vitamins that may offer some benefits. It’s important to consult a doctor or registered dietitian for personalized advice, but here are some general dietary considerations:

• Include: Whole grains, fruits (especially pears, cherries, and citrus fruits), vegetables (including root vegetables and leafy greens), nuts and seeds, healthy fats (like olive oil), and plenty of water.
• Consider supplements: Under a doctor’s supervision, you might explore adding folic acid, vitamin B12, vitamin C, pantothenic acid (vitamin B5), copper, and zinc to your regimen.
• Spices: Ginger and turmeric are often used in traditional medicine and may have some anti-inflammatory properties. However, more research is needed to confirm their effectiveness in vitiligo.
• Foods that you should avoid:
• Fats, high salt
• Bread and white flour
• Smoked and fried food
•             Chocolate
•             Dark tea
• Butter and margarine
• Alcohol
•             Coffee
•             Ice cream
• Mustard
•             Tamarind
• Fish and seafood
• Pickled cucumber
• Processed foods

Final word

Vitiligo can be a visually concerning condition, but it’s important to remember that it’s not contagious and there are treatment options available. If you experience any symptoms of vitiligo, such as white patches on your skin or hair color changes, consult a dermatologist, a doctor specializing in skin conditions. Early diagnosis and treatment can help manage the condition and improve your quality of life.
