Hashimoto's thyroiditis is an autoimmune disease which is associated with high serum levels of anti-thyroglobulin (anti-Tg) and anti-thyroid perosxidase (anti-TPO) antibodies in serum. My sister has had Hashimoto since several years ago and has got dermatomyositis (polymyositis associated with skin rashes) since one year ago. she has elevation of anti-Tg during each episode of detoriation of muscle weakness. Is there any experince to remove thyroid gland for controling muscle weakness?
