Sex hormones can have a significant impact on thyroid function. Estrogen and progesterone, in particular, play essential roles in regulating thyroid hormones. Imbalances in these hormones can lead to thyroid dysfunction.
Estrogen, for instance, can increase thyroid-binding globulin (TBG) levels, a protein that transports thyroid hormones in the blood. When TBG levels rise due to higher estrogen levels, it can lead to an apparent increase in thyroid hormones, potentially masking thyroid issues.
On the other hand, fluctuations in sex hormones during menopause or other hormonal changes can sometimes contribute to thyroid problems.
