Vitiligo
  • Vitiligo is a chronic skin problem, which causes
    the loss of skin colour resulting in white and
    uneven patches. These blotches can appear
    anywhere on the skin. Vitiligo problem occurs
    when melanocytes cells die. Melanocytes are the
    cells within the skin, which provides skin with
    its original colour and protect it from
    ultraviolet rays. Vitiligo can affect people of
    any age and there is no permanent cure for this
    skin condition, but treatment can help to stop it
    spreading to the other parts of the body. The
    patches once appear may never go for the rest of
    the life. There are more than 1 million cases of
    vitiligo every year in the India. However,
    vitiligo is not a contagious disorder.

Causes of Vitiligo
  • The prime cause of vitiligo is the death of
    melanocytes, the skin cells. Melanin is the
    pigment produced by the melanocytes, which gives
    skin its original color. When melanocytes are,
    destroyed, skin tends to lose its original colour
    as a result, there is a formation of large and
    uneven patches on the skin. However, the exact
    cause of death of skin cells is yet to be
    determined. Some possible causes of vitiligo
  • Hyperthyroidism
  • Autoimmune disorder Immune system of the body
    destroys own body cells.
  • Pernicious Anaemia
  • Chemical exposure
  • Nervous system disorder
  • Genetic

Symptoms
  • Appearance of uneven white patches and the high
    degree of de-pigmentation on the various parts of
    the body is an only symptom of vitiligo. The skin
    starts to lose its colour first from hands, arms,
    feet, lips, and face. As the condition,
    progresses a patient may also start to see white
    patches around the armpits, eyes, abdomen area,
    and nostrils. The skin also loses its ability to
    protect it from ultraviolet rays, which can cause
    excessive sunburn. If, vitiligo is left
    untreated, it may lead to the development of skin
    cancer.

Diagnosis of Vitiligo
  • Before starting the treatment, diagnosis of
    vitiligo is done to know the severity of this
    skin condition. A skin doctor may perform a
    physical examination and asks patients about
    their medical history and other questions such as
    when did condition started or is patient allergic
    to anything. The diagnostic test for vitiligo
    includes 
  • Blood test
  • Thyroid test
  • Biopsy

Treatments
  • There are various medicines and procedures for
    the treatment of vitiligo. A dermatologist will
    choose the best combination of medicines and
    procedures for the treatment of patients with
    vitiligo. The treatment of vitiligo can help in
    the reduction of white spots on the skin. Some
    treatments of vitiligo are listed
    below.  Re-pigmentation- The colour of skin can
    be revived using re-pigmentation. The
    re-pigmentation treatment includes many methods
    such as grafting, dyes, micro-pigmentation,
    phototherapy, and creams with specific compounds,
    which are beneficial for the skin.  Narrow band
    phototherapy- Involves the use of laser for
    minimising the visibility of white
    patches.  De-pigmentation- This treatment is,
    done when there is a considerable affected area.
    De-pigmentation removes the skin pigment from the
    other unaffected areas of the body in order to
    match the whiter area. This is a long-term
    procedure and makes take up to one year before
    completion.
