❤️❤️❤️

There’s something special about caring for the people who protect our community every single day. ❤️🌊

We are proud to provide the annual physicals for our incredible Navarre Beach Lifeguards. These men and women train hard, stay ready, and put others first — and it’s an honor to help make sure they’re healthy, strong, and prepared for another safe season on our beaches.

Thank you for what you do to keep Navarre safe. We’ve got your back — just like you’ve got ours. 💪🏼🏖️

Why Stress Can Block Thyroid Hormone

(Bonus Post)

How High Cortisol Interferes with Thyroid Function

Your body doesn’t just make thyroid hormone — it has to convert it.

• T4 = storage form (inactive)
• T3 = active form your cells actually use

When stress is chronic, the body releases cortisol.

High cortisol can block the conversion of T4 → T3 and instead push T4 into Reverse T3 (rT3).

🔁 Reverse T3 is inactive and blocks T3 receptors, slowing metabolism even more.

⚠️ Why This Matters

You can have:
• Normal TSH
• Normal T4
• Normal labs on paper

…and still feel:
• Exhausted
• Foggy
• Cold
• Depressed
• Inflamed
• Unable to lose weight

This is especially common in:
• Chronic stress or burnout
• Trauma history
• Overtraining
• Calorie restriction
• Chronic illness
• Perimenopause & menopause

🧪 When a Reverse T3 Lab Is Helpful

Reverse T3 testing may be useful when:
• TSH is “normal” but symptoms persist
• Free T3 is low-normal
• Cortisol is elevated or dysregulated
• The patient is on T4-only medication and not improving

📌 Reverse T3 helps explain WHY the hormone isn’t working, not just whether it exists.

🧩 The Big Picture
This is why thyroid care is not just about prescribing T4.

Supporting thyroid function often means:
• Addressing stress & cortisol
• Supporting adrenal health
• Optimizing sleep
• Correcting nutrient deficiencies
• Reducing inflammation
• Individualizing medication strategy

✨ Treat the stress physiology, not just the TSH.

💊 How to Take Thyroid Medication Correctly

(Post 7 of 7)

Proper use makes a huge difference.

Best practices:

• Take first thing in the morning
• Empty stomach
• Wait 30–60 minutes before food
• Separate from iron, calcium, magnesium by 4 hours
• Take consistently, same time daily
• Dose adjustments should be guided by labs + symptoms

📌 More medication isn’t better — the right dose is.

📣 If you’re exhausted, gaining weight, losing hair, or just don’t feel like yourself — don’t accept “everything looks normal” as the final answer.

💊 How Is Hypothyroidism Treated?

(Post 6 of 7)

Treatment depends on symptoms, labs, and the individual.

Options may include:

• T4-only therapy (levothyroxine)
• Combination T4/T3 therapy
• T3-only therapy (selected patients)
• Lifestyle & nutritional support
• Treating autoimmune triggers

👉 Medication replaces hormone — it does NOT treat autoimmunity.

🛡️ Can Hypothyroidism Be Prevented or Slowed?

(Post 5 of 7)

Not all cases are preventable, but progression can often be slowed.

Helpful strategies:
• Reduce chronic inflammation
• Support gut health
• Address nutrient deficiencies (iron, selenium, iodine, zinc)
• Manage stress & sleep
• Avoid unnecessary immune triggers
• Monitor labs regularly

✨ Treating the root cause matters.

I will never stop recommending an anti-Inflammatory diet, exercise, sleep, sunshine, and stress reduction!

🧪 How Do We Test for Hypothyroidism?

(Post 4 of 7)

Diagnosis requires more than one lab.
Important tests:
• TSH (often elevated)
• Free T4
• Free T3
• Thyroid antibodies (TPO, TgAb)
• Iron, B12, vitamin D (often overlooked)
• Inflammatory markers (when indicated)

📌 A “normal” TSH does NOT always mean optimal thyroid function and most providers only order a TSH.

What Causes Hypothyroidism?

(Post 3 of 7)

The most common causes include:

• Autoimmune thyroid disease (Hashimoto’s)
• Thyroid removal or radioactive iodine
• Iodine deficiency or excess
• Certain medications
• Chronic inflammation or infection
• Postpartum thyroid changes

👉 Hashimoto’s is an immune issue first, hormone issue second.

Comment Hashimoto’s, if you'd like more information on autoimmune thyroid disease.

⚠️ Symptoms of Hypothyroidism
(Post 2 of 7)

Common symptoms include:
• Fatigue or exhaustion
• Weight gain or difficulty losing weight
• Cold intolerance
• Depression or low motivation
• Brain fog & memory issues
• Hair loss or thinning eyebrows
• Dry skin & brittle nails
• Constipation
• Heavy or irregular periods

📌 Many women are told “it’s just stress, aging, or hormones.”

Often—it’s the thyroid.

LET’S TALK HYPOTHYROIDISM

(Post 1 of 7)

What Is Hypothyroidism?

Hypothyroidism happens when the thyroid gland is underactive and does not produce enough thyroid hormone (T3 and/or T4).

Your thyroid affects:
• Metabolism
• Energy
• Mood
• Weight
• Heart rate
• Hormones

When it slows down, everything slows down with it.

This ⬇️⬇️⬇️

Most people are told to take iron the moment ferritin drops.

Fatigue, hair loss, pregnancy, heavy cycles. The reflex is iron.

But iron is not a neutral nutrient. It is a redox active metal. Unbound iron participates in the Fenton reaction and generates hydroxyl radicals. Those radicals damage lipids, vascular endothelium, and mitochondria.

Hemoglobin reflects oxygen delivery. If hemoglobin is normal, oxygen transport is intact. Ferritin is a storage protein and also an acute phase reactant that shifts with inflammation. A low ferritin in isolation does not automatically mean impaired oxygen delivery.

Dr. Thomas Levy, board certified cardiologist, stated clearly that with a normal hemoglobin, iron cannot be too low, and he does not advocate high iron foods. His framework centers on oxidative injury and catalytic iron.

Genetics matter here. Variants in HFE can increase iron absorption. Transferrin and ferroportin variants influence transport and export. Hepcidin regulation shifts iron distribution during inflammation. Low ceruloplasmin impairs copper dependent iron mobilization. In some individuals, iron accumulates more easily and increases oxidative load even when labs appear borderline.

Iron corrects true anemia. It should not be supplemented reflexively.

Before adding iron, evaluate hemoglobin, ferritin, transferrin saturation, TIBC, CRP, and copper status. Consider genetic handling of iron. Iron should restore physiology, not increase oxidative stress in the process.

Metabolic syndrome Post 1: What Is Metabolic Syndrome (and Why You’ve Probably Never Been Told You Have It)

🧠 Metabolic Syndrome isn’t a disease—it’s a warning system.

It’s a cluster of metabolic abnormalities that dramatically increase your risk for:
• Heart disease
• Type 2 diabetes
• Stroke
• Fatty liver disease

🚩 Most people with metabolic syndrome feel normal—until they don’t.

📌 It’s not about weight alone.
📌 It’s about how your body handles blood sugar, fat, and inflammation.

💬 Comment “WARNING” if you’ve never heard this explained before.
