Most women with hypothyroidism from Hashimoto's thyroiditis have elevated thyroid peroxidase



Most women with hypothyroidism from Hashimoto’s thyroiditis have elevated thyroid peroxidasec thyroids, a pattern seen on ultrasound that is compatible with thyroiditis.

Similarly, research has found that women with PCOS have more hypoechogenic thyroids when compared to women without PCOS. Women with PCOS also have higher thyroid antibody levels (for example, TPO antibodies) and are more likely to have a goiter (enlarged thyroid gland).

Overall, this scientific data suggest that perhaps PCOS is a type of autoimmune disease or that women with PCOS are more vulnerable to developing autoimmune diseases.
