Vitiligo is a skin condition that causes loss of pigmentation, leading to white or light patches on different parts of the body. While vitiligo is not contagious or life-threatening, it can have a deep emotional and psychological impact on those affected.
With the right medical guidance and timely care from experienced specialists like Dr. K. C. Dharam Kumar, individuals can better understand the condition and explore effective treatment options at the Best Dermatology Centres in BTM Layout.
What Is Vitiligo?
Vitiligo is a chronic skin disorder that occurs when melanocytes, the cells responsible for producing melanin (skin pigment) stop functioning or are destroyed. This results in patchy depigmentation of the skin, hair, and sometimes even the mucous membranes.
Vitiligo can affect:
- Face and lips
- Hands and feet
- Arms and legs
- Scalp (causing premature greying of hair)
What Causes Vitiligo?
Although the exact cause of vitiligo is still being researched, dermatologists have identified several contributing factors:
1. Autoimmune Response
The most common theory suggests that vitiligo is an autoimmune condition where the immune system mistakenly attacks melanocytes.
2. Genetic Factors
Vitiligo can run in families. Individuals with a family history of vitiligo or autoimmune diseases may have a higher risk.
3. Oxidative Stress
An imbalance between free radicals and antioxidants in the body can damage melanocytes, triggering vitiligo.
4. Neural Factors
Certain chemicals released from nerve endings in the skin may be toxic to pigment-producing cells.
5. Triggers
Vitiligo may be triggered or worsened by:
- Severe emotional stress
- Skin trauma (cuts, burns, or friction)
- Sunburn
- Hormonal changes
Types of Vitiligo
Dermatologists classify vitiligo into different types based on its pattern:
- Non-Segmental Vitiligo – The most common type, affecting both sides of the body symmetrically
- Segmental Vitiligo – Appears on one side or area of the body
- Focal Vitiligo – Limited to a small area
- Universal Vitiligo – Extensive depigmentation across the body
How Is Vitiligo Diagnosed?
Diagnosis usually involves:
- Detailed skin examination
- Medical and family history
- Wood’s lamp examination
- Blood tests (to rule out autoimmune conditions)
Vitiligo Treatment Options
While vitiligo cannot always be completely cured, modern dermatology offers several effective ways to control and improve pigmentation, including:
- Topical medications
- Immunomodulators
- Phototherapy (NB-UVB therapy)
- Oral medications (when required)
- Surgical options for stable vitiligo
