Asheville Thyroid Doctor for Hypothyroidism

If you're struggling with stubborn fatigue, brain fog, weight gain, or mood swings—and your labs keep coming back “normal”—you’re not alone.

At Caring for the Body, we understand how disheartening it can be to feel like something is off in your body, yet your concerns are brushed aside or dismissed by conventional medicine. Many of our patients come to us after years of being told their thyroid is “fine,” despite living in a constant state of exhaustion, frustration, and confusion.

Dr. Cynthia Libert, M.D., a board-certified family physician and certified functional medicine expert in Asheville, takes a radically different approach. She listens closely, digs deeper, and partners with you to uncover the true root causes of your thyroid dysfunction. Whether it’s Hashimoto’s disease, hormonal imbalances, nutrient deficiencies, or hidden inflammation, we look at the whole picture—not just your TSH levels.

Through a thoughtful blend of advanced testing, integrative therapies, lifestyle medicine, and compassionate support, Dr. Libert helps patients not just manage hypothyroidism—but actually heal and feel like themselves again.

What Is Hypothyroidism?

Hypothyroidism—also known as an underactive thyroid—is a condition where your thyroid gland doesn’t produce enough thyroid hormones to meet your body’s needs. These hormones are vital for regulating your metabolism, energy levels, brain function, digestion, temperature control, fertility, and more.

When your thyroid is sluggish, every system in your body can feel like it’s running on low battery. That’s why hypothyroidism can lead to symptoms like fatigue, weight gain, brain fog, constipation, dry skin, depression, and irregular menstrual cycles.

The most common cause of hypothyroidism in the United States is Hashimoto’s thyroiditis, an autoimmune condition in which the body’s immune system mistakenly attacks the thyroid gland. Unfortunately, this root cause is often missed or overlooked in standard care.

Conventional testing often relies on just one marker—TSH (thyroid-stimulating hormone)—which doesn’t give a complete picture of thyroid health. At Caring for the Body, we go beyond TSH to look at thyroid antibodies, free T3, free T4, reverse T3, and more. This comprehensive view helps us identify dysfunction early and tailor your treatment precisely.

Certain factors may increase your risk for hypothyroidism, including:

Being female (especially during perimenopause or after childbirth)
Family history of thyroid or autoimmune disease
Exposure to chronic stress or environmental toxins
Nutrient deficiencies (iodine, selenium, zinc, B12)
Having other autoimmune conditions

Untreated or poorly managed hypothyroidism can profoundly impact your quality of life. But with a holistic, functional medicine approach, it’s possible to restore balance, support your thyroid naturally, and feel vibrant again.

Common Symptoms of Hypothyroidism

Hair Loss or Thinning Eyebrows
Especially thinning of the outer third of the brows

Constipation
Sluggish digestion or infrequent bowel movements

Depression or Anxiety Mood changes, irritability, or lack of motivation

Brain Fog
Difficulty concentrating, forgetfulness, or mental sluggishness

Irregular or Heavy Periods
Hormonal imbalances that disrupt the menstrual cycle

Dry Skin and Brittle Nails
Changes in skin texture and nail strength

Root Causes of Hypothyroidism We Investigate

Hashimoto’s Thyroiditis (Autoimmune)

The most common cause of hypothyroidism, Hashimoto’s is an autoimmune condition where your immune system mistakenly attacks the thyroid gland, leading to inflammation and reduced hormone production.

Estrogen Dominance / Adrenal Dysfunction

Hormonal imbalances, such as too much estrogen or insufficient adrenal function (often caused by chronic stress), can disrupt thyroid function. Estrogen dominance, in particular, can interfere with thyroid hormone metabolism.

Gut Health and Intestinal Permeability

Leaky gut and dysbiosis (imbalanced gut bacteria) are often overlooked but can directly affect thyroid function. Inflammation and immune system activity in the gut can disrupt thyroid hormone conversion and utilization.

Nutrient Depletions

Certain nutrients are critical for thyroid function. Deficiencies in iodine, selenium, zinc, iron, and vitamin B12 can impair the production of thyroid hormones and lead to hypothyroidism.

Epstein-Barr Virus, Mold/Mycotoxins

Chronic infections like Epstein-Barr Virus (EBV) and exposure to mold/mycotoxins can trigger autoimmune responses and damage thyroid tissue, leading to long-term thyroid issues.

Environmental Toxins and Heavy Metals

Toxins in our environment—such as pesticides, BPA, and heavy metals like mercury—can disrupt thyroid hormone production and function, making it harder for your thyroid to do its job.

Chronic Stress and HPA Axis Dysregulation

When you’re under prolonged stress, your body’s hormonal balance (HPA axis) can become dysregulated, which impacts not just your thyroid but other hormones like cortisol and sex hormones, exacerbating hypothyroid symptoms.

Our Comprehensive Healing Approach

Advanced Diagnostic Testing

We utilize cutting-edge lab testing to uncover what standard panels often miss, including:

DUTCH Hormone Testing – for a complete view of cortisol, estrogen, progesterone, testosterone, and their metabolites
GI-MAP (Gut Testing) – identifies gut imbalances, infections, and inflammation that impact thyroid health
Micronutrient & Antibody Panels – to detect deficiencies in key nutrients like selenium, iodine, zinc, and to screen for autoimmune thyroid markers
Environmental & Toxin Screening – including heavy metals, mold/mycotoxins, and endocrine disruptors

Customized Protocols

Once we understand your unique biochemistry, we design a personalized healing plan that may include:

Anti-inflammatory, thyroid-supportive nutrition guidance
Targeted supplementation to correct deficiencies and support hormone balance
Herbal medicine and adaptogens to support the immune system and adrenal glands
