Postpartum Thyroiditis: A Naturopathic Perspective on Supporting Thyroid Health After Birth

Author: Elyse Johnson, Naturopath

The weeks and months after giving birth are a time of major physical and emotional adjustment. For some women, this includes unexpected shifts in thyroid function—something we call postpartum thyroiditis.

From a naturopathic perspective, this condition is more than just a hormonal hiccup. It’s a signal from your body that deeper support may be needed—through nutrition, lifestyle, and care for your immune and nervous systems.

What is Postpartum Thyroiditis?

Postpartum thyroiditis (PPT) is an inflammation of the thyroid gland that typically occurs within 12 months of childbirth. It often presents in two phases:

• First, a hyperthyroid phase (overactive thyroid), where symptoms may include anxiety, irritability, and rapid weight loss.

• Then, a hypothyroid phase (underactive thyroid), marked by fatigue, low mood, and difficulty losing weight.

In most cases, PPT is temporary, but for some, it can progress into permanent hypothyroidism.

Why Does It Happen?

A few key factors contribute to postpartum thyroiditis:

• Immune rebound: After pregnancy, the immune system ramps back up and may mistakenly attack thyroid tissue.

• Nutrient depletion: Nutrients like iodine, selenium, iron, and B vitamins are critical to thyroid function and often become depleted during pregnancy and breastfeeding.

• Stress and sleep deprivation: These can interfere with thyroid hormone conversion and increase inflammation.

• Pre-existing thyroid or autoimmune history: Women with Hashimoto’s, type 1 diabetes, or a family history of thyroid issues are at higher risk.

Is It Permanent?

In many cases, the thyroid function normalises within 6–12 months. However, about 20–40% of women may go on to develop lifelong hypothyroidism—especially if thyroid antibodies are present.

How to Support Yourself Postpartum

Whether you’re currently navigating postpartum thyroiditis or simply want to protect your thyroid health, these foundational naturopathic principles can help:

1. Rebuild Your Nutrient Stores
Include foods rich in:

• Iodine (seaweed, eggs, seafood)

• Selenium (Brazil nuts, mushrooms)

• Zinc (meat, pumpkin seeds)

• Iron (liver, leafy greens)

• B vitamins (whole grains, eggs)

2. Support Your Nervous System
Simple, sustainable practices like breathwork, time in nature, and realistic expectations around rest can help modulate your stress response and support thyroid hormone function.

3. Be Mindful with Caffeine
If you’re feeling jittery or anxious, especially during a hyperthyroid phase, try reducing caffeine and opt for calming herbal teas when appropriate.

4. Nourish Your Gut
A healthy gut helps regulate immune function. Focus on fibre-rich whole foods, fermented foods, and anti-inflammatory herbs under guidance.

5. Work with a Holistic Practitioner
If you’re experiencing fatigue, low mood, or other thyroid symptoms postpartum, seek support. A full thyroid panel (including antibodies) can provide clarity, and tailored nutrition and supplementation can make a big difference—especially while breastfeeding.

You deserve to feel well. Not just for your baby, but for you.
