Vitiligo and Diabetes


Vitiligo manifests as an acquired depigmentation disorder, marked by the loss of cutaneous melanocytes. In contrast, diabetes mellitus is a metabolic condition that results in elevated blood sugar levels. Moreover, both vitiligo and diabetes, particularly type 1, are known to be autoimmune diseases, therefore, individuals with vitiligo may have a heightened risk of developing diabetes type 1 or vice versa.

However, to dive deeper into the in-depth details of the association between vitiligo and diabetes mellitus, keep on reading the article.

What is Diabetes Mellitus?

Diabetes mellitus is a metabolic disorder affecting carbohydrate metabolism, characterized by elevated blood glucose levels (hyperglycemia). It occurs due to inadequate insulin production (type 1 diabetes) or ineffective cellular response to insulin (type 2 diabetes). Insulin is a hormone, released by the pancreas, which is vital for facilitating the transportation of blood glucose into cells.

Do Vitiligo and Diabetes Share Common Symptoms?

Vitiligo primarily involves depigmentation of the skin, leading to white patches, while diabetes manifests as high blood sugar levels, and can lead to increased urination, thirst or unexplained weight loss. However, both conditions share a potential link at an immunological level.

Symptoms of Vitiligo

  • Loss of skin color, leading to the appearance of white patches
  • Patches commonly appear on the face, hands, wrists, feet, and areas exposed to the sun
  • Hair within the affected skin areas may lose its natural color
  • It can often occur on both sides of the body symmetrically
  • The color of the retinal layer inside the eyes may change

The Association Between Vitiligo and Diabetes

Research suggests a potential association between diabetes and vitiligo. The emergence of vitiligo and diabetes simultaneously could indicate autoimmune mechanisms within the same individual. Due to prolonged diabetes mellitus, the melanocytes could be impaired, leading to the formation of anti-melanocyte antibodies and the destruction of melanocytes subsequently, resulting in vitiligo. One notable aspect of the association between vitiligo and diabetes mellitus may stem from a shared pathogenesis involving the autoreactive cytotoxic T cell, causing destruction in both cases.

In another research, it was found that vitiligo exhibits connections with various autoimmune diseases such as autoimmune thyroid disease and adult-onset type 1 diabetes mellitus. Individuals with vitiligo and their immediate family members display a susceptibility to this cluster of autoimmune conditions, indicating a shared genetic foundation. However, another study found that individuals with vitiligo had a risk of developing diabetes mellitus 3.30 times higher, emphasizing the interlink between these two conditions. Given that vitiligo is considered an autoimmune disease like type 1 diabetes, diabetics may face an elevated risk of developing vitiligo compared to those without type 1 diabetes.

Treatment for Vitiligo

There are various therapies that are aimed at restoring skin tone such as topical medications, certain drugs to slow down autoimmune response, and light therapy. One notable prevention strategy can be protecting oneself from UV rays, including sunlight. Additionally, ongoing research by clinical research organizations is seeking potential treatment options that could offer potential solutions for vitiligo management.


The link between vitiligo and diabetes appears to be complex, involving potential autoimmune mechanisms and shared genetic factors. It is crucial for dermatologists to consider these associations, which can potentially help in the early detection of health issues in individuals with vitiligo. Additionally, individuals with vitiligo must be cautious when it comes to monitoring indicators such as blood glucose levels, blood pressure, and BMI. Seeking healthcare professional consultation is crucial in times of abnormal changes in these indexes.
