Your microbiome isn’t just about digestion. �It helps regulate inflammation, immune balance, and even neurotransmitters in the gut.
Antibiotics can be necessary, but they also shift this delicate balance by reducing microbial diversity.
When key species are lost, it can open the door for problematic bacteria or yeast to take over.

This is part 2 of my series on rebuilding the gut after antibiotics. Stay tuned all week as we talk about how to support your microbiome the right way.

Antibiotics save lives, but they can leave your gut vulnerable. This week we’re talking about how to rebuild your gut after antibiotics and reduce risks like C. diff and yeast overgrowth. Follow along!

3 Reasons Your Thyroid Might Be Low

Low thyroid is rarely random. Most often, it comes down to:�

1️⃣ Nutrient deficiencies – missing key “groceries” like selenium, iodine, and tyrosine.
�2️⃣ Autoimmune activity – antibodies can attack your thyroid years before labs show a problem.�
3️⃣ Chronic stress – high cortisol can block thyroid function and hormone conversion.

Understanding why your thyroid is low is the first step to feeling better.

Stress is a root cause of so many health issues, which is why learning how to regulate the nervous system is essential. Deep breathing helps signal to the body that it’s safe by activating the parasympathetic nervous system.
Even if you have anxiety or take medication, this still matters. Deep breathing may not feel effective at first, but that doesn’t mean you should stop. You’re building muscle memory and retraining the system. Your body’s own GABA response from slow, intentional breaths is powerful.
Even nine deep breaths an hour can make a difference.

In addition to iodine and selenium, Tyrosine is a key amino acid needed to build thyroid hormone. It comes from protein, especially animal foods, and it’s also the precursor to dopamine. When stress is high, the nervous system and the thyroid compete for tyrosine, often leaving the thyroid short.
Low thyroid can be about intake, absorption, and stress all at once.

3 Reasons Your Thyroid Might Be Low

Low thyroid is rarely random. The three most common root causes I see are lack of key nutrients (especially selenium for T4 to T3 conversion), inflammation from the immune system, and chronic stress disrupting hormone signaling.

Supporting the thyroid means looking beyond labs and addressing nutrition, inflammation, and the stress response.

Let’s talk about what your thyroid actually needs.

Iodine is essential for thyroid function. It’s the rate-limiting nutrient for making T3 and T4—meaning without enough iodine, your thyroid simply can’t produce these hormones efficiently.

While iodine deficiency isn’t talked about much, it can be more common than we think. Iodine-rich foods like certain fish, seaweed, kelp, and sardines aren’t everyday staples for most people. Add to that the reality of depleted soil, and even vegetables that once provided trace minerals may not anymore.

When iodine intake is low, thyroid function can suffer. This is one of the key reasons functional medicine looks at nutrient status when evaluating low thyroid function, because sometimes the issue isn’t the thyroid itself, but what it’s missing.

How to test your thyroid properly:

A full thyroid panel gives a much clearer picture than a TSH alone. While TSH is often used as a basic screening tool, it doesn’t tell the whole story.
When you’re doing a deeper dive, a comprehensive panel typically includes TSH, Free T3, Free T4, Reverse T3, and thyroid antibodies. These markers help reveal how well your thyroid hormones are being produced, converted, and used by the body.
This kind of testing is often ordered by an endocrinologist, naturopathic doctor, functional medicine practitioner, or a primary care provider trained in thyroid health. When you’re looking for root causes, you usually need to go beyond a cursory TSH.

Hypothyroid symptoms often show up quietly and build over time. Common signs include unexplained weight gain, persistent fatigue, hair thinning or hair loss, constipation, and dry skin. Many people also notice low mood, low energy, and a lack of motivation that just doesn’t lift.
These fatigue-based symptoms together can paint a classic picture of low thyroid function. If this sounds familiar, it may be a sign your body is asking for a deeper look, beyond just surface-level symptoms.

Let’s talk about your thyroid.
Your thyroid is a major metabolic regulator, guiding how your body uses energy, repairs tissue, and turns over cells. It plays a central role in how you feel day to day.
But it doesn’t work alone. The thyroid is closely connected to the pituitary, the adrenals, and your hormones. These systems are constantly balancing each other.
That’s why in functional and naturopathic medicine, we don’t look at the thyroid in isolation. To understand low thyroid function, we look at the whole system, because that’s where the real answers are.
