Vitiligo is a de-pigmenting skin disorder that is caused by the selective loss of melanocytes. This loss of melanocytes results in the discoloration of the skin patch. The conditions that lead to the onset of this disease include oxidative stress and environmental factors. This disease is an autoimmune disorder and is not life-threatening itself, but there are chances for vitiligo to be associated with other underlying diseases.

There has been a clinical association detected in the patients of vitiligo and thyroid disorders. The evidence is that T cells that lead to thyroid disorders are found in the periphery of affected lesions of vitiligo patients. Some cases of vitiligo have also been found in association with other endocrine disorders and various underlying diseases.

Is Vitiligo associated with other medical conditions?


One should be highly advised to see a dermatologist if any abnormality or skin discoloration is noticed. There are also a few at-home observations that can be recommended for the diagnosis of vitiligo and its relation with a thyroid disorder and underlying diseases.

The following signs can be detected through self-examination:

  • Faded or dull patches on the skin
  • Swelling of the lymph nodes, especially in the neck area
  • Pain, itching, or lesion formation on the affected areas
  • Discoloration inside the nose’s mucous membrane and mouth

Signs and Symptoms

If there is a suspicion of thyroid disorders in a vitiligo patient, then the next step is to check whether the thyroid disorder is hyperthyroidism or hypothyroidism.

Patients with hypothyroidism and vitiligo will suffer from the following symptoms:

  • Weight gain
  • Hair loss
  • Cold intolerance
  • Dry skin
  • Constipation

Patients with hyperthyroidism and vitiligo will suffer from the following symptoms:

  • Nervousness
  • Heat intolerance
  • Skin Irritation 

Tests for Vitiligo associated with other disorders

Skin biopsy is done to out rule the possibilities of any cancers associated with vitiligo. In this procedure, a small tissue of the skin is extracted and examined under the microscope for the confirmation or exclusion of other underlying diseases such as skin cancers, etc. The following blood tests will be recommended by your medical practitioner for screening of a thyroid disorder:

  • Complete blood count test (CBC)
  • Thyroid stimulation hormone (TSH) test
  • Reverse T3 (RT3)
  • Folate/B12


There are chances of association of vitiligo with other autoimmune disorders, especially thyroid disorders. Once you are diagnosed with this disease, you should seek medical help as soon as possible. Early treatment can control the vitiligo’s spread and severity.
