What Thyroid and Hormone Labs Should You Get Before and After Explant Surgery?
(Based on a recent interview with Dr. Amie Hornaman discussing thyroid and hormone health in the context of implant-associated symptoms and explant recovery - https://www.youtube.com/watch?v=iKYsT12qRGI)
Patients preparing for explant surgery ask me some version of the same question constantly: why do I feel so off, even when my regular bloodwork comes back "normal"? On a recent podcast episode, I brought on Dr. Amie Hornaman, founder of the Better Thyroid and Hormone Institute and creator of the Fixer supplement line, to walk through exactly this. Nearly every patient she sees who reports systemic symptoms has some layered combination of hypothyroidism, testosterone suppression, and estrogen imbalance, and standard lab panels routinely miss all three. Dr. Amie's own path into this work started with her personal thyroid and hormone struggles, which is part of why her approach to patients leans so heavily on individualized testing rather than a one-size-fits-all protocol.
Chronic Inflammation, Not a Single Diagnosis
Implant-associated symptoms do not have a dedicated diagnostic code, which makes them easy to dismiss in a standard 15-minute appointment. I think of it as chronic inflammation, the kind we see across many patient populations, that can become more complex once a medical device is involved. My team recently reviewed 700 of our explant specimens and found bacterial contamination in roughly 29 to 30 percent of them, a rate consistent with our published PCR research (Whitfield et al., Microorganisms 2024), the largest PCR-tested explant capsule series published to date. That level of contamination has been linked, in laboratory and clinical literature, to a more active immune response in some patients.
Thyropause: The Shift Dr. Amie Sees Constantly
Dr. Amie uses the term thyropause to describe the hormonal transition many women go through starting in their 40s, when thyroid symptoms often begin surfacing whether or not a formal diagnosis follows. She estimates this shows up in the majority of the women she treats, many of whom have been told their labs are "normal" for years without anyone reassessing which labs were actually run.
To explain how autoimmune conditions like Hashimoto's develop, Dr. Amie frames it as a three-legged stool. The first leg is genetic predisposition, a family history of autoimmune conditions such as type 1 diabetes, psoriasis, Crohn's disease, celiac disease, or Hashimoto's itself. The second leg is baseline gut inflammation and permeability, something everyone carries to some degree depending on diet, lifestyle, and how much gut health has already been addressed. The third leg is a triggering stressor, which can be a hormonal shift, pregnancy, perimenopause, starting or stopping birth control, a major life stressor, or a medical device being placed in or removed from the body.
Dr. Amie describes it as a light switch: genetic risk can sit dormant for years in the off position until a trigger flips it on. That is why so many women can trace their symptom onset back to a specific moment, whether that was after a first pregnancy, after turning 40, after a move, or after a surgical procedure. As I noted in our conversation, autoimmune conditions were described in medical literature well before the first breast implants were placed in 1962, so this is not a simple cause-and-effect story. It is one contributing piece among several, including genetics and other environmental triggers.
Why Thyroid Dosing Can Shift After Surgery
This is a detail patients are rarely warned about. As inflammation resolves after a procedure, thyroid medication (synthetic or desiccated) can become more bioavailable, meaning a dose that was well matched before surgery may become too strong afterward. I have seen this shift be significant enough to require hospitalization for thyroid storm in a small number of cases. Anyone on thyroid medication should watch symptoms closely after surgery and get labs rechecked rather than assuming a pre-surgical dose still applies.
The Thyroid Panel Dr. Amie Actually Recommends
A standard primary care thyroid panel usually stops at TSH and sometimes free T4. Dr. Amie recommends going further:
- Free T3, the active, unbound thyroid hormone that reaches cellular receptors. Every cell in the body has a receptor site for T3 specifically, which is part of why this marker matters so much. Many patients on T4-only medication continue feeling unwell because T4 monotherapy works for a much smaller share of patients than commonly assumed, meaning most people need some combination of T4 and T3, or T3 alone, to feel fully optimized.
- Reverse T3, the body's survival hormone. Dr. Amie explained that reverse T3 exists for a reason: in a true survival scenario, injured or fighting for your life, the body does not need to burn fat, think clearly, or digest food efficiently, so reverse T3 rises to shut those systems down. The problem is when reverse T3 stays elevated without a true survival trigger, often due to chronic inflammation, insulin resistance, or estrogen dominance. In that case, patients can be given more and more T4 without ever feeling better, because the extra hormone keeps getting diverted toward the survival pathway instead of the active one.
- TPO and TG antibodies, the two markers used to help identify Hashimoto's thyroiditis.
Our Female SHARP Blood Profile (https://www.drrobssolutions.com/products/female-sharp-blood-profile) was built to capture this fuller thyroid and hormone picture in a single draw, rather than the abbreviated version most patients get by default.
The Hormone Panel Worth Requesting
Dr. Amie also outlined the sex hormone markers she considers essential, particularly for women navigating symptoms alongside implant-associated concerns or explant recovery.
Total estrogen, not estradiol alone. Estradiol (E2) is the most potent estrogen and the one most closely tracked in perimenopause and menopause, but Dr. Amie also checks estrone (E1), which becomes more relevant when evaluating growth-related risk, and estriol (E3), which is typically only elevated during pregnancy. Looking at all three gives a fuller picture of how a woman is producing and metabolizing estrogen.
Progesterone, alongside estrogen, to understand the balance between the two rather than looking at either hormone in isolation.
Free and total testosterone, since total testosterone alone does not indicate how much is actually available for the body to use.
DHT (dihydrotestosterone), which in women can be associated with thinning hair at the crown and, in some cases, cystic acne, though not every woman with elevated DHT experiences these effects. Dr. Amie noted that before starting testosterone therapy in a patient with elevated DHT, she will often introduce supportive options like saw palmetto or nettle to help direct testosterone metabolism down a more favorable pathway.
SHBG (sex hormone binding globulin), which shows whether hormones are bound up and unavailable to do their job at the cellular level. A patient can have hormone levels that look adequate on paper while still feeling symptomatic if too much of that hormone is bound to SHBG rather than free to act.
She also pointed out that libido is influenced by far more than testosterone alone, including estrogen levels, stress, and overall self-perception, especially for women. Treating libido concerns as a testosterone-only problem is one of the most common oversimplifications she sees.
Why "This Hormone Doesn't Work" Is Usually a Dosing Problem
Dr. Amie compared poorly run hormone clinics to a rushed cosmetic procedure: a generic protocol applied to every patient, with little follow-up or retesting. She sees the aftermath of that pattern often, patients who were put on the same standardized hormone regimen as everyone else with no individualized testing and no plan to reassess. When a patient says a hormone "isn't working," the more accurate explanation, in her experience, is that the dose or combination has not been matched to that individual's physiology and labs, not that the hormone itself failed. This is also true for thyroid medication. A patient who keeps having their T4 dose raised without ever having reverse T3 checked may keep getting worse instead of better, because the additional hormone is being diverted toward the survival pathway rather than the active one.
This is also why gut health and basic nutritional status come up so often in these conversations. Hormones and thyroid medication cannot be absorbed or converted properly if the gut is not functioning well, which affects sleep, mood, and recovery capacity well beyond the thyroid or reproductive system alone. Addressing gut health is not a separate project from hormone optimization. It is part of the same process.
How the SHARP Framework Applies to This Discussion
Hormonal balance is one of the core pillars of SHARP, my Strategic Holistic Accelerated Recovery Program, alongside immune support, gut health, and structured preparation before and after surgery. Dr. Amie's approach reflects SHARP thinking directly: treating inflammation as a root contributor to symptoms, individualizing lab testing instead of relying on a standard panel, and recognizing that hormone needs shift as inflammation resolves after a procedure. For patients preparing for explant surgery, our pre- and post-surgery essentials collection (https://drrobssolutions.com/collections/pre-post-surgery-essentials) is designed around that same whole-body approach.

Frequently Asked Questions
Why would my thyroid medication need adjusting after explant surgery?
As post-surgical inflammation resolves, thyroid medication can become more bioavailable, so a previously well-matched dose may need to be lowered. Rechecking labs after surgery is important.
What is thyropause?
It is a term Dr. Amie Hornaman uses for the hormonal shift many women experience starting around age 40, when thyroid symptoms often begin appearing.
My TSH and free T4 are normal. Why do I still feel unwell?
Those two markers do not capture free T3, reverse T3, or thyroid antibodies, all of which can explain persistent symptoms even when standard labs look fine.
Is DHT connected to hair thinning in women?
In some women, elevated DHT is associated with thinning at the crown and, in some cases, cystic acne, though not every woman with elevated DHT experiences these effects.
Do implants play a role in hormone or thyroid symptoms?
Some patients with implants report systemic symptoms alongside thyroid or hormone changes. Chronic inflammation associated with a medical device may be one contributing factor among several, and a full evaluation is the appropriate next step for anyone with concerns.
