Your labs say "normal."
Your body says otherwise.
Fatigue that doesn't lift. Weight that won't move. Hair falling out. Brain fog so thick you can't think clearly. And a TSH that keeps coming back in range. You're not imagining it โ and "normal" isn't good enough. Dr. Alissia Zenhausern-Pfeiffer, NMD, FABNE runs the full picture and treats what's actually driving your symptoms.
"After years of being told my thyroid was fine while feeling terrible, Dr. Zen ran the labs my GP wouldn't order. Within months, I had energy again. I only wish I'd found her sooner."
โ Former Patient, NMD WellnessYou've been dismissed.
You've been told it's stress, or aging, or nothing.
Thyroid and metabolic conditions are among the most under-diagnosed and under-treated in women's health. Most patients arrive here after years of being told their labs are fine โ while living with symptoms that are anything but. If any of these sound familiar, we can help.
"Your TSH is normal" โ but you're exhausted
You sleep 8 hours and wake up tired. Coffee barely works. You drag through your days wondering why no one can figure out what's wrong. The answer is often in the labs that aren't being ordered.
Hashimoto's diagnosis โ no real plan
You were told you have Hashimoto's and given a prescription โ or told to "watch and wait." But no one explained what Hashimoto's actually is, why your immune system is attacking your thyroid, or what to do about it.
Weight that won't respond to anything
You're eating well. You're exercising. The scale doesn't move, or keeps creeping up. This is not a willpower problem โ it's a metabolic one. And it almost always has thyroid and insulin resistance components.
Thyroid and fertility or pregnancy
You're TTC and your thyroid has never been properly optimized. Or you're pregnant and worried about your levels. Thyroid function has profound effects on ovulation, implantation, miscarriage risk, and fetal development.
Brain fog, mood changes, hair loss
You don't feel like yourself. You forget things. You're anxious or depressed in ways that don't match your life circumstances. Hair is falling out in the shower. These are thyroid symptoms โ and they respond to proper treatment.
On medication but still symptomatic
You're already on levothyroxine โ but you still don't feel well. Your doctor says your TSH is fine. But TSH is only one piece of the picture, and T4 medication alone doesn't work for everyone.
If this is your list,
your thyroid deserves a closer look.
The labs your doctor ordered
may only be showing you half the picture.
TSH (thyroid stimulating hormone) is a pituitary signal โ it tells you how loudly the brain is calling for more thyroid hormone. It does not tell you how much thyroid hormone is actually being produced, whether it's being converted into its active form, or whether your immune system is attacking your thyroid. Many women with significant thyroid dysfunction have TSH values that fall within the standard reference range.
The most commonly ordered test โ but a poor standalone measure. TSH measures the brain's signal to the thyroid, not thyroid output. Optimal TSH for fertility and symptom resolution is typically 1.0โ2.0, not just "within range."
The biologically active form that actually enters your cells. Low Free T3 โ even with normal TSH โ causes every classic hypothyroid symptom. Often low in women who don't convert T4 to T3 efficiently.
The storage form of thyroid hormone. Low Free T4 indicates inadequate thyroid hormone production. Often normal in early Hashimoto's while T3 is already declining.
Elevated antibodies confirm Hashimoto's thyroiditis. These are often present for years before TSH becomes abnormal โ meaning the autoimmune attack is underway long before standard labs flag anything. This is one of the most missed diagnoses in women's health.
Insulin resistance worsens thyroid conversion. Inflammation drives Hashimoto's antibody production. These cannot be treated in isolation from thyroid function โ they are part of the same system.
Comprehensive care for every
thyroid and metabolic condition.
Hashimoto's Thyroiditis
The most common cause of hypothyroidism โ an autoimmune condition that attacks the thyroid. We address the autoimmune root cause alongside hormone optimization, not just hormone replacement.
Hypothyroidism
Underactive thyroid from any cause, including Hashimoto's, post-thyroiditis, or primary thyroid dysfunction. We optimize your levels and evaluate whether T4 alone is adequate for your physiology.
Postpartum Thyroiditis
Thyroid dysfunction that develops after pregnancy โ often missed because symptoms overlap with normal postpartum recovery. Can present as temporary hyperthyroidism followed by hypothyroidism.
Thyroid & Fertility
Thyroid optimization is a critical component of fertility care. Suboptimal thyroid function affects ovulation, implantation, and early pregnancy. TSH should be below 2.5 when trying to conceive.
Insulin Resistance & Metabolic Syndrome
Insulin resistance worsens thyroid conversion, drives inflammation, and contributes to PCOS and weight challenges. Treated comprehensively alongside thyroid optimization โ not separately.
Thyroid-Related Weight Challenges
Weight that doesn't respond to diet and exercise when thyroid and metabolic function are suboptimal. We address the full hormonal picture โ not just calorie balance.
Thyroid Nodules & Goiter
Monitoring, nutritional support (including iodine balance and selenium), and integrative co-management alongside your endocrinologist or PCP.
Not just replacing hormones.
Addressing what's driving the dysfunction.
Thyroid care at NMD Wellness goes beyond writing a levothyroxine prescription. We evaluate the full hormonal, immune, nutritional, and metabolic picture โ and build a protocol that addresses all of it.
Full thyroid panel โ not just TSH
TSH, Free T3, Free T4, TPO antibodies, thyroglobulin antibodies, and relevant metabolic markers. Interpreted against optimal ranges โ not just laboratory reference ranges designed to catch severe disease.
Autoimmune root cause evaluation
For Hashimoto's patients, we investigate what's driving the immune attack: gut permeability, food sensitivities (especially gluten), nutrient deficiencies (selenium, vitamin D, zinc), environmental triggers, and chronic infections. Reducing antibody burden is the goal โ not just managing TSH.
Thyroid hormone optimization
When medication is needed, we evaluate whether T4 alone is sufficient or whether T3 support (liothyronine or compounded desiccated thyroid) would better address your symptoms. Many patients feel dramatically better on combination therapy who were told T4 was working because their TSH was normal.
Metabolic & insulin support
Insulin resistance worsens thyroid conversion and drives inflammation that fuels Hashimoto's. We address both systems together โ with targeted nutrition, supplementation, and lifestyle strategies specific to your metabolic picture.
Ongoing monitoring & adjustment
Thyroid function changes with seasons, stress, pregnancy, postpartum, and age. Your protocol evolves with you โ with regular lab monitoring and direct access to Dr. Zen between visits.
What it feels like when
someone finally looks deeper.
"After years of being told my thyroid was fine while feeling terrible, Dr. Zen ran the labs my GP wouldn't order. Within months, I had energy again. I only wish I'd found her sooner."โ Former Patient, NMD Wellness
"After an at-home hormone test, I realized I had low ovarian reserve and was utterly shocked. Dr. Zen not only identified that I had Hashimoto's โ something no one had caught โ her care plan helped me lower my thyroid antibodies, improve my thyroid function, and even improve my AMH levels. We are now 22 weeks pregnant with our daughter."โ Lauren B.
"Dr. Zen uncovered that I had Hashimoto's โ something my OBGYN completely missed. Once we addressed my thyroid, I started getting positive OPKs for the first time. No IVF needed."โ Jessica L.
Dr. Alissia Zenhausern-Pfeiffer,
NMD, FABNE
Dr. Zen is a board-certified naturopathic endocrinologist โ one of a small number nationally to hold the FABNE designation. She specializes in thyroid disorders, Hashimoto's thyroiditis, and the intersection of thyroid health with fertility, metabolic function, and overall hormonal wellbeing.
This work is personal. Dr. Zen's own undiagnosed Hashimoto's was the reason she struggled to conceive her first child. She knows what it feels like to have labs come back normal while your body tells a different story. She knows the confusion of a diagnosis that comes with no real explanation and no real plan. That experience is a large part of why she built a practice specifically designed to find what gets missed โ and why Hashimoto's and thyroid-related fertility are at the center of everything she does.
Her thyroid patients come to her after years of normal TSH results that didn't explain their symptoms, or after starting medication and still not feeling well. She runs the full panel, interprets it against optimal ranges, and builds a protocol that addresses the autoimmune root cause โ not just the number on a lab report.
Questions you might be wondering.
- Thyroid hormone optimization โ ensuring TSH, Free T3, and Free T4 are all at optimal levels, not just within range
- Antibody reduction โ identifying and removing what's driving the immune attack (often gut permeability, gluten sensitivity, nutrient deficiencies, or chronic infection)
- Autoimmune support โ anti-inflammatory nutrition, selenium, vitamin D optimization, stress management, and gut health restoration
You've been living with this
long enough.
A normal TSH doesn't mean your thyroid is fine. It means one number is in range. There is so much more to look at โ and a discovery call is where we start.
