Skin pigmentation

[Harthill42]

Dear friends of Thyroid U.K

I am on holiday and I have noticed around my chest area that there is a visible change

I always use sun screen to protect

The area looks like vitiligo, has anyone had this reaction?

Could this be due to medication? 75 mcg T4

& 15 mcg T3.

I have continued to keep the area out of the sun.

Many thanks

I havnt heard this being tied to medication, but i have seen it as a symptom of b12 deficiency

Thank you.

I do have a B12 deficiency so this could be a cause.
