Thyroid Dysfunction

What is Thyroid Dysfunction?

Thyroid dysfunction occurs when the thyroid gland — a small, butterfly-shaped gland in the front of your neck — does not produce the right amount of hormones needed to regulate metabolism, energy, mood, and cellular function. The thyroid influences nearly every system in the body, including heart rate, digestion, body temperature, brain function, weight balance, and hormonal signaling.

 

There are two primary types of thyroid dysfunction:

 

  • Hypothyroidism — the thyroid is underactive and produces too little thyroid hormone
  • Hyperthyroidism — the thyroid is overactive and produces too much thyroid hormone

 

Thyroid dysfunction can also include autoimmune thyroid disorders, such as Hashimoto’s (leading to hypothyroidism) and Graves’ Disease (leading to hyperthyroidism).

 

At First Call DPC, we understand that thyroid symptoms are real — even when standard labs are “normal.” We look deeper than basic screening tests to understand your full thyroid function, metabolic response, and symptom patterns. You deserve answers, clarity, and a treatment plan that helps you feel like yourself again.

What Causes Thyroid Dysfunction?

Thyroid dysfunction can be influenced by many interconnected factors, including:

Autoimmunity

Hashimoto’s Thyroiditis is the most common cause of hypothyroidism. The immune system attacks the thyroid and gradually reduces its function.

Chronic Stress & Adrenal Dysregulation

High cortisol levels can block thyroid hormone conversion and uptake.

Nutrient Deficiencies

Low levels of iodine, selenium, zinc, iron, magnesium, and vitamin D can impair thyroid hormone production and conversion.

Hormonal Changes

Shifts in estrogen, progesterone, and testosterone (especially during perimenopause, menopause, and andropause) affect thyroid activity.

Gut Health Imbalances

Poor digestion or dysbiosis can interfere with hormone conversion and immune function.

Environmental Toxins

Exposure to plastics, pesticides, heavy metals, and endocrine disruptors can impair thyroid signaling.

Thyroid dysfunction is rarely caused by one problem — it is an interplay of metabolism, stress physiology, hormones, and immune balance.

And with the right approach, these systems can be supported and restored.

What Symptoms Will I Experience With Thyroid Dysfunction?

Symptoms vary depending on whether you have low or high thyroid function — but many people experience:

Common Symptoms of Hypothyroidism (Low Thyroid Function)

Fatigue or low energy

Weight gain or difficulty losing weight

Cold intolerance

Hair thinning or hair loss

Dry skin

Brain fog or slow processing

Constipation

Menstrual cycle changes

Common Symptoms of Hyperthyroidism (High Thyroid Function)

Anxiety or irritability

Rapid heartbeat or palpitations

Heat intolerance

Weight loss despite normal or increased appetite

Tremors or shakiness

Insomnia

Muscle weakness

Frequent bowel movements

Many patients say:

  • “I knew something was wrong, but I kept being told my labs were ‘normal.’”
  • “I feel tired all the time, no matter how much I sleep.”
  • “My mood and metabolism just aren’t responding like they used to.”

Thyroid symptoms are real — and deserve to be taken seriously.

What Should I Try at Home Before Seeing a Provider?

You can begin supporting thyroid health with simple, daily habits:

Prioritize Protein and Balanced Meals

Stable blood sugar supports thyroid hormone signaling.

Reduce Chronic Stress Where Possible

Even small shifts — such as breathwork, walking, or quiet breaks — help regulate cortisol.

Limit Excess Alcohol and Processed Sugar

Both contribute to inflammation and hormone disruption.

Ensure Adequate Sleep

Your thyroid and adrenal glands rely on deep rest to regulate hormone production.

Add Gentle Movement

Walking, stretching, yoga, or resistance training support metabolism and energy.

If these steps aren’t enough — that’s not a failure. It’s a sign your thyroid system needs targeted medical support.

Best Treatment Options for Thyroid Dysfunction

At First Call DPC, we treat thyroid dysfunction using a root-cause and physiology-based approach, not just medication alone.

Your treatment may include:

Comprehensive Thyroid Hormone Optimization

We evaluate and treat:

  • TSH
  • Free T4
  • Free T3
  • Reverse T3
  • Thyroid antibodies
    We ensure your active thyroid hormone is available and usable in the body — not just present on paper.

Autoimmune Support (if applicable)

 We calm the immune system and support gut health to reduce inflammatory flare patterns.

Nutrient Repletion

Selenium, zinc, iron, iodine (when appropriate), vitamin D, omega-3s, and magnesium are carefully replenished.

Peptide Therapy for Cellular Repair

Certain peptides help support mitochondrial function, immune modulation, and stress recovery.

Hormone + Metabolic Balance

Because thyroid hormone does not operate in isolation — we treat the entire hormonal system.

Lifestyle and Nervous System Support

We help your daily routine align with your healing physiology — not work against it.

Our goal is not just to normalize labs — but to help you feel energized, clear, confident, and strong again.

Our Process for Treating Thyroid Dysfunction

At First Call DPC, we take a thoughtful, evidence-based approach:

Comprehensive Consultation

We start by understanding your symptoms, stress patterns, sleep, lifestyle, and personal goals.

 

Advanced Thyroid & Metabolic Lab Testing

We go beyond standard thyroid screening to understand the full picture.

Clear, Personalized Interpretation

We explain your results in clear, supportive language — so you feel informed and empowered.

Tailored Treatment Plan

Your care is individualized — not formula-based.

Consistent Access & Monitoring

You have direct access to your provider — because healing requires partnership, not occasional check-ins.

At First Call DPC, we bring together modern medicine, precision testing, and human-centered care — because your thyroid affects your whole life, and you deserve support that reflects that. When you’re ready to restore your energy, metabolism, clarity, and confidence — we’re your first call.
