Thyroid Imbalance Treatment
Precision Support for Your Metabolism, Mood, and Energy – Dr. Brenda Marshall, MD
The thyroid may be small, but it has a big impact on your body—from how you burn energy and regulate mood to how well you sleep, think, and manage weight. When thyroid function is even slightly off, the effects can ripple through nearly every system.
At Dr. Brenda Marshall’s practice, thyroid care goes far beyond standard lab results. She specializes in identifying and treating both overt and subclinical thyroid imbalances—using a whole-body, root-cause strategy to restore true balance.
Common Thyroid Conditions Treated
- Hypothyroidism (underactive thyroid)
- Hyperthyroidism (overactive thyroid)
- Hashimoto’s Thyroiditis (autoimmune thyroid disorder)
- Subclinical Hypothyroidism
- Thyroid-related weight issues, fatigue, or depression
- Postpartum or perimenopausal thyroid shifts
Symptoms That Could Point to Thyroid Dysfunction
- Fatigue or sluggishness
- Weight gain or difficulty losing weight
- Cold intolerance or always feeling cold
- Constipation
- Dry skin, hair thinning, or hair loss
- Brain fog or poor concentration
- Depression or anxiety
- Menstrual irregularities
- Hoarseness or neck fullness
What Makes Dr. Marshall’s Approach Unique?
Most conventional care relies solely on TSH levels—and may overlook early dysfunction or autoimmune activity. Dr. Marshall’s functional medicine model includes:
- Comprehensive Thyroid Panels: TSH, Free T3, Free T4, Reverse T3, TPO/Tg antibodies
- Nutrient Evaluation: Iron, ferritin, selenium, iodine, zinc, vitamin D, B12
- Adrenal & Cortisol Testing: Because thyroid and adrenal systems work in tandem
- Autoimmune & Inflammation Screening: Especially for Hashimoto’s-related symptoms
- Gut Health Assessment: The majority of T3 (active thyroid hormone) is converted in the gut
Treatment May Include:
- Bioidentical thyroid hormone support (T3, T4, or combination therapy)
- Nutritional therapy to address deficiencies
- Gut healing and detox protocols to support conversion
- Lifestyle coaching to improve sleep, stress, and metabolism
- Addressing triggers like gluten sensitivity, infections, or toxin exposure
“You can’t fix thyroid symptoms by looking at just one number. We have to look at the whole story—and that’s how we get real results.” – Dr. Brenda Marshall
🧠 Education: Hashimoto’s and Autoimmune Thyroid Disease
Up to 90% of hypothyroid cases are autoimmune in nature. If you’ve never had your thyroid antibodies tested, you may be missing a key piece of the puzzle.
Dr. Marshall routinely screens for Hashimoto’s and helps patients calm immune dysregulation through targeted lifestyle and nutritional interventions—not just hormones.

❓ Frequently Asked Questions (FAQs)
Q: My doctor said my thyroid levels are normal, but I still have symptoms. Can you help?
A: Yes. Many patients are told their TSH is “normal,” but still experience classic thyroid symptoms. Dr. Marshall looks at a full thyroid panel, symptoms, and contributing systems like the gut and adrenals to find and treat underlying imbalances.
Q: What is Hashimoto’s, and how is it treated differently?
A: Hashimoto’s is an autoimmune condition that attacks the thyroid. Treating it effectively involves not just hormone support, but also calming the immune system through dietary, gut, and lifestyle therapies.
Q: Will I need to take thyroid medication for life?
A: Not always. Some patients do well with temporary support while the root cause is addressed. Others may need long-term low-dose therapy. Dr. Marshall customizes this based on lab results, symptom response, and patient goals.
Q: Can thyroid issues affect mental health or fertility?
A: Absolutely. Thyroid imbalances are closely linked to anxiety, depression, brain fog, and reproductive challenges. Addressing them can lead to profound improvements in mood and hormonal regulation.
Q: What kind of testing do you offer?
A: In addition to a full thyroid panel, Dr. Marshall may recommend micronutrient testing, adrenal function tests, gut microbiome analysis, and autoimmune markers depending on your history and symptoms.
