Do other diseases commonly occur together with vitiligo?
Comorbidities in Patients with Vitiligo: A Systematic Review and Meta-Analysis
Last reviewed
In short
People with vitiligo more often have accompanying autoimmune diseases such as thyroid disease, alopecia areata, and lupus. Therefore, it is necessary to examine not only the skin but the whole body together.
During consultations, I have noticed that it is particularly common for patients with vitiligo to also have thyroid abnormalities or other autoimmune symptoms. Since vitiligo is rooted in autoimmunity, this may be expected. Still, I wanted to confirm whether my impressions were accurate with actual numbers. Relevant reports are scattered across multiple papers, and there was no compilation that organized them all in one place. Therefore, I gathered all 78 observational studies from around the world and pieced them together into one big picture.
Q1 What conditions commonly occur alongside vitiligo?
Most were autoimmune diseases. Alopecia areata, discoid lupus, Sjögren's syndrome, myasthenia gravis, systemic lupus erythematosus, and rheumatoid arthritis were significantly more common in patients with vitiligo compared to controls. These diseases all share the commonality that the immune system attacks the body itself — a root shared with vitiligo. For example, alopecia areata was about 2.6 times more common in patients with vitiligo than in those without. Among them, alopecia areata had the strongest association with vitiligo.
Major autoimmune diseases with elevated risk in vitiligo patients (compared to controls)
| Comorbid condition | Odds ratio (OR) | In simple terms |
|---|---|---|
| Alopecia areata | 2.63 | About 2.6 times |
| Discoid lupus | 2.54 | About 2.5 times |
| Sjögren's syndrome | 2.50 | About 2.5 times |
| Myasthenia gravis | 2.30 | About 2.3 times |
| Systemic lupus erythematosus | 1.96 | About 2 times |
| Rheumatoid arthritis | 1.82 | About 1.8 times |
Q2 Were there conditions other than autoimmune diseases?
Yes, there were. Thyroid disease, diabetes and metabolic syndrome, as well as sensorineural hearing loss and eye abnormalities, were more common in patients with vitiligo. Pigment cells are present not only in the skin but also inside the ear and in the eyes. For this reason, we believe the immune response in vitiligo may also affect these areas. This shows that vitiligo is not a condition confined to the skin. However, a "slightly higher risk" does not mean it "will definitely occur." There is no need to be overly anxious.
Closing remarks
As a result, vitiligo is no longer dismissed as a simple cosmetic issue. For those who need it, there is now evidence to recommend thyroid function tests or screening for autoimmune symptoms. Because this is the first time scattered pieces have been assembled into clear numbers, it will serve as a reference for guiding treatment direction. Detecting hidden diseases early is as important as treating the white patches.
