Why I am passionate about treating patients with hypothyroidism.
When we address not just the numbers, we can see how our thyroid is a symptom of the whole system, and when we care for the whole system, we not only improve the numbers, but also help patients feel more energized, and more empowered and engaged in optimizing their own lifestyle.
My approach to treating hypothyroidism is...
We are not just take 1 pill to treat the numbers. We start by addressing the person, the symptoms that's bothering them, they health outcomes they want to see, and then, we learn together what the thyroid does and what autoimmunity is. From there, we figure out what factors positively and negatively affect our immune system and our thyroid, and then we support healing through good medication practices, nutrient support and good lifestyle habits.
