Hashimoto’s vs. Hypothyroidism: What’s the Difference?

Many people—including some doctors—don’t fully understand the difference between Hashimoto’s vs. hypothyroidism. But knowing the distinction is crucial for proper treatment. So, what is the difference?

When it comes to thyroid disorders, Hashimoto’s vs. hypothyroidism is one of the most common confusions. Hypothyroidism is when the thyroid doesn’t produce enough hormones, while Hashimoto’s is an autoimmune disease that attacks the thyroid. Since Hashimoto’s often leads to hypothyroidism, they are closely linked—but they require different treatment approaches.

Over 90% of people with hypothyroidism have Hashimoto’s, so it’s my approach to treat people as if their immune system isn’t functioning optimally, and go from there.

What Is Hypothyroidism?

Hypothyroidism happens when the thyroid gland doesn’t produce enough thyroid hormone and can be caused by iodine deficiency, stress, or lifestyle habits.

A lack of thyroid hormone will lead to a sluggish metabolism, weight gain, and fatigue among other symptoms.

What Is Hashimoto’s?

Hashimoto’s is an autoimmune disease where the body attacks healthy thyroid tissue which can ultimately lead to hypothyroidism.

Since the body is under attack from the immune system this can lead to increased inflammation and symptoms that fluctuate from hypo to hyper. When people are hypo, they have a sluggish metabolism and fatigue, but they can get some hyperthyroid symptoms too like heart palpitations, anxiety and insomnia.

Key Differences Between Hashimoto’s & Hypothyroidism

Why It Matters for Treatment

Unlike standard hypothyroidism treatment, Hashimoto’s requires more than just hormone replacement. Supporting the immune system through lifestyle changes is key. Some strategies include:

✔️  An anti-inflammatory diet (like gluten-free, dairy-free, and nutrient-dense foods)

✔️ Acupuncture for immune regulation and stress reduction

✔️ Managing stress levels, as cortisol fluctuations can trigger flares

✔️ Addressing gut health, since 70% of the immune system is in the gut
