Thyroid and Adrenal Treatment
Your doctor checked your TSH and said your thyroid is fine. But you're still gaining weight, losing hair, freezing cold, and exhausted. TSH alone misses most thyroid dysfunction. We run a full panel: free T3, free T4, reverse T3, thyroid antibodies. And we test cortisol patterns because thyroid and adrenal function are inseparable.
Your Thyroid Isn't 'Fine'
Thyroid dysfunction is the most underdiagnosed condition in America. Hashimoto's thyroiditis alone affects an estimated 14 million Americans, most of whom don't know they have it. Why? Because the standard screening test (TSH) doesn't catch it until the gland is significantly damaged.
TSH can be "normal" while your free T3 (the active thyroid hormone) is low, your reverse T3 is high (blocking thyroid activity), or your antibodies are elevated (your immune system is attacking your thyroid). All of these produce symptoms: fatigue, weight gain, hair loss, cold intolerance, brain fog, constipation, depression. And all of them are invisible on a standard TSH test.
The adrenal glands compound the problem. When you're chronically stressed, cortisol stays elevated. High cortisol suppresses thyroid hormone conversion (T4 to T3) and increases reverse T3. So even if your thyroid gland is working, the hormone can't get into your cells. Treating the thyroid without addressing cortisol is like pushing the gas pedal with the parking brake on.
“These glands have a complex relationship with each other. In conventional medicine there's this idea that the thyroid is off on an island, the adrenal glands are off by themselves, and the ovaries are separate. All of these hormones are in the blood together.”

Full Thyroid and Adrenal Evaluation
Our thyroid panel includes TSH, free T3, free T4, reverse T3, TPO antibodies, and thyroglobulin antibodies. We also assess cortisol patterns, sex hormones (which interact directly with thyroid), and nutrient cofactors (iodine, selenium, zinc, iron, vitamin D).
- Hashimoto's identification. Thyroid antibodies tell us if your immune system is attacking your thyroid. This changes the entire treatment approach. Conventional medicine waits until the gland fails. We intervene early.
- T3 optimization. Many patients convert T4 poorly to active T3. We identify conversion issues and address them through nutrient support, stress management, and when needed, T3 supplementation.
- Reverse T3 patterns. Elevated reverse T3 blocks thyroid receptors even when other numbers look normal. This is a stress and inflammation pattern that requires a different approach than standard thyroid medication.
- Cortisol restoration. HPA axis dysfunction (adrenal fatigue) impairs thyroid function at every level. We assess cortisol patterns and restore healthy adrenal function.
- Autoimmune triggers. If Hashimoto's is present, we look for triggers: gut permeability, gluten cross-reactivity, infections, and toxin exposure that drive the immune attack.
Treatment is personalized. Some patients need thyroid medication. Others need gut repair and stress management. Most need a combination. We monitor and adjust until symptoms resolve and labs optimize.
What Causes Thyroid Problems That Your Doctor Keeps Missing?
The standard thyroid screening in conventional medicine is a single test: TSH. That's a signaling hormone from the pituitary gland. Checking TSH alone is like checking whether your thermostat sent a signal, without looking at whether the furnace actually turned on, whether the heat reached the rooms, or whether someone left the windows open.
A full thyroid evaluation requires six markers, not one:
- TSH. The signaling hormone. Useful but incomplete on its own.
- Free T3. The active thyroid hormone. This is what actually drives your metabolism, energy, temperature regulation, and mental clarity. It can be low while TSH sits in "normal" range.
- Free T4. The storage form that must be converted to T3 to work. Many patients make enough T4 but convert it poorly.
- Reverse T3. A blocking hormone. When your body is under chronic stress or inflammation, it converts T4 into reverse T3 instead of active T3. Your thyroid numbers look fine on paper, but the hormone can't get into your cells.
- TPO Antibodies. Detects Hashimoto's thyroiditis, where your immune system attacks your thyroid. Affects an estimated 14 million Americans, most undiagnosed.
- Thyroglobulin Antibodies. A second autoimmune marker that confirms or rules out immune-driven thyroid damage.
We run all six on every patient. In our experience treating over 3,000 patients, roughly half the people who were told their thyroid was "fine" have a pattern that shows up only on the expanded panel. Subclinical hypothyroidism, poor T4-to-T3 conversion, elevated reverse T3, or early Hashimoto's with antibodies climbing while TSH stays within range.
If you've been told your thyroid is normal but you're still gaining weight, losing hair, freezing cold, and exhausted, your doctor probably only ran one test. Read more about what a full thyroid panel reveals.
Is Adrenal Fatigue Real, and How Is It Treated?
The medical establishment says "adrenal fatigue" isn't a real diagnosis. They're half right. Your adrenal glands don't get tired. But HPA axis dysfunction (the technical term) is real, measurable, and well-documented in the research.
The HPA axis is the communication loop between your hypothalamus, pituitary gland, and adrenal glands. It controls your cortisol rhythm: high in the morning to wake you up, gradually dropping through the day, lowest at night so you can sleep. Chronic stress, poor sleep, inflammation, and gut dysfunction can break this rhythm.
Patients with HPA axis dysfunction describe the same pattern over and over. Dragging themselves out of bed. A brief window of feeling okay mid-morning. Crashing hard around 2 to 3pm. Then getting a second wind at 10pm when they should be winding down. Their doctor says their cortisol is "normal" because they ran a single morning blood draw, which misses the pattern entirely.
What makes this especially frustrating is that adrenal and thyroid function are inseparable. High cortisol suppresses the conversion of T4 to active T3. It increases reverse T3. It depletes the nutrients your thyroid needs to function (selenium, zinc, iodine). You can take thyroid medication and still feel terrible if the HPA axis is dysregulated. That's why we always evaluate both systems together.
Treatment depends on the pattern. Some patients need cortisol support with adaptogens like ashwagandha and rhodiola. Others need gut repair because chronic gut inflammation is driving the cortisol elevation. Nutrient repletion (vitamin C, B5, magnesium) supports adrenal recovery. And in cases where thyroid medication is needed, addressing the adrenal side first often makes the thyroid medication work better.
Dr. Sasha Rose manages most thyroid and adrenal cases at our Maine clinic. The evaluation is thorough, the treatment is personalized, and progress is tracked with follow-up labs, not guesswork.

What We Test for This Condition
TSH
The standard screening test. Useful as a starting point but misses most subclinical thyroid dysfunction when used alone.
Free T3
The active thyroid hormone. Low free T3 is the most common finding in patients with 'normal' TSH who still feel terrible.
Free T4
The storage hormone your body converts to active T3. Low T4 with normal TSH indicates central hypothyroidism.
Reverse T3
A blocking hormone that increases under stress and inflammation. Elevated reverse T3 explains why thyroid medication alone doesn't always work.
TPO Antibodies
The primary marker for Hashimoto's autoimmune thyroiditis. Elevated antibodies mean your immune system is attacking your thyroid gland.
Thyroglobulin Antibodies
A second autoimmune marker that catches Hashimoto's cases that TPO alone misses.
Cortisol
Reveals HPA axis dysfunction. A single morning draw misses the pattern. Elevated or flattened cortisol directly impairs thyroid function.
Selenium
Required for T4-to-T3 conversion. Deficiency is common and directly impairs thyroid hormone activation.
Zinc
Supports thyroid hormone production and immune regulation. Low zinc worsens both thyroid and adrenal function.
Iron/Ferritin
Iron is required for thyroid peroxidase, the enzyme that makes thyroid hormone. Low ferritin is a hidden contributor to thyroid dysfunction.

Real Patient Stories
Hear from patients who came to Med Matrix with this condition.
Carla
Carla came to Med Matrix in severe physical distress: heart palpitations, very high blood pressure, extreme muscle fatigue, and pain so bad she could barely walk from one end of her house to the other. Her regular doctor and even the hospital had not addressed the root causes, dismissing her symptoms as age-related. Within a week and a half of her first Med Matrix appointment, she was pain-free, sleeping later, and moving freely. She credits thyroid treatment (T3 alongside T4) as a key piece, and now actively recommends Med Matrix to everyone she knows.
“The first time I remember I actually cried at night when I laid in bed and I thought, 'Oh my gosh, I don't hurt. I don't hurt.' And I kept trying to make myself move and I literally started crying because I just didn't hurt.”
Victoria
Victoria has multiple autoimmune conditions including dermatomyositis, type 1 diabetes, Graves disease, and connective tissue disease. Before Med Matrix, hard prescription medications with significant side effects left her barely able to get off the couch. Through functional medicine, dietary changes, and targeted supplements, her Graves disease thyroid levels returned to normal within roughly five months, her joint pain improved dramatically, and her overall quality of life is nearly back to what it was before.
“It was looking at more of the root cause, not just treating symptoms. That wasn't working for my symptoms with normal medical doctors.”

FAQ
Thyroid and Adrenal Treatment FAQ
Yes. TSH can be normal while free T3 is low, reverse T3 is high, or antibodies are elevated. These patterns produce all the classic thyroid symptoms but are invisible on a TSH-only test. We test the full panel.
Hashimoto's is an autoimmune condition where your immune system attacks your thyroid gland. It's the most common cause of hypothyroidism and affects women 7x more than men. It's diagnosed by testing thyroid antibodies (TPO and thyroglobulin), which most doctors don't routinely check.
The medical term is HPA axis dysfunction. It means your stress response system is dysregulated, typically from chronic stress. Cortisol patterns become abnormal, causing fatigue, poor sleep, afternoon crashes, and impaired thyroid function. It's real, testable, and treatable.
When labs indicate it's needed, yes. We use both T4-only and combination T4/T3 medications depending on your conversion ability. Many patients also benefit from addressing nutrient deficiencies and stress patterns alongside medication.
