Liz, yes there is a relationship between vitilago and thyroid, and YES, it is important to keep enough calcium in your body. Thyroid hormone (our own, or synthetic) pulls calcium out of our bones faster than we can ordinarily replace it, and puts both men and women at risk for osteoporosis. Weight-bearing exercise is important, and for women, estrogen replacement therapy. Welcome to the group. Leave your e-mail address next time and I’ll put you in touch with another woman who had her thyroid removed when she was three years old.
