As a Functional Medicine doctor, I believe that knowledge is power — and well-informed patients tend to have better outcomes. Understanding your condition is the first step toward reclaiming your health.
If you’ve been diagnosed with hypothyroidism or Hashimoto’s thyroiditis, it’s essential to understand what is happening in your body, why symptoms persist despite normal lab results, and how you can support your thyroid naturally.

What is Hypothyroidism and Hashimoto’s?
Hypothyroidism occurs when the thyroid gland is underactive and does not produce enough thyroid hormones.
Hashimoto’s thyroiditis is an autoimmune condition — the most common cause of hypothyroidism — where the immune system mistakenly attacks the thyroid.
This can lead to a gradual decline in thyroid function over time and is often missed or underdiagnosed in conventional care.
Common Symptoms You Might Notice:
Fatigue or exhaustion
Cold intolerance
Weight gain or difficulty losing weight
Brain fog and difficulty concentrating
Constipation
Dry skin and brittle nails
Hair thinning
Menstrual irregularities
Mood changes, such as anxiety or low mood
