Welcome to our Thyroid Series of blog articles. This article covers hyperthyroidism and how to address it using Functional Medicine and diet.

Hyperthyroidism: Hyperthyroidism, or overactive thyroid, is when the thyroid produces too much thyroid hormones.

1.2% of people in the US have hyperthyroidism, which is approximately 1 person out of 100 (National Institutes of Health, 2016). Hyperthyroidism is less common that underactive thyroid or hypothyroidism.

Women are 2 to 10 times more likely than men to develop hyperthyroidism (National Institutes of Health, 2016).
