Thyroid Treatment When “Normal” Test Results Don’t Explain Your Symptoms
Are you exhausted or fatigued? Struggling with unexplained weight gain? Experiencing cold extremities? Thinning hair? These and more are symptoms of low thyroid function. Possibly you have had your thyroid checked and your doctor told you, “Your thyroid tests are normal?”
Thousands of people suffer from thyroid symptoms while their standard lab tests come back “within range.” The truth is that conventional thyroid testing often misses critical indicators of thyroid dysfunction.
With extensive training and years of experience in Functional Medicine, Bio-identical Hormone Replacement Therapy, weight management, thyroid health, and more, we practice with a forward-thinking philosophy rooted in precision, prevention, innovation, and longevity.
At iRenewHealth we treat thyroid and hormone dysregulation, metabolic dysfunction, and more.
Rather than masking symptoms, our mission is to uncover and treat the root causes—offering advanced, integrative care that empowers long-term wellness.
At iRenewHealth, our comprehensive approach to thyroid health includes more extensive testing to uncover the real causes of your symptoms and provide truly effective solutions.

The Benefits of Thyroid Treatment: A Path to Renewed Energy and Health
1. Increased Energy and Reduced Fatigue
One of the most immediate benefits of treating hypothyroidism is a noticeable boost in energy. Fatigue is a hallmark symptom, and with proper hormone replacement therapy, many patients feel more alert, motivated, and capable in their daily lives.
2. Improved Metabolism and Weight Management
An underactive thyroid slows your metabolism, often leading to weight gain and difficulty losing weight. Treatment helps restore normal metabolic function, making it easier to maintain a healthy weight with proper nutrition and activity.
3. Enhanced Mood and Mental Clarity
Hypothyroidism can lead to depression, anxiety, and brain fog. Balancing thyroid hormones can significantly improve emotional well-being, mental focus, and memory.
4. Healthier Skin, Hair, and Nails
Thyroid hormones play a role in cell regeneration and repair. Treatment often leads to improvements in dry skin, thinning hair, and brittle nails, helping patients feel more confident and vibrant.
5. Better Heart and Digestive Health
Untreated hypothyroidism can raise cholesterol levels and affect heart function. It may also slow digestion, causing constipation. Treatment supports a healthier cardiovascular system and improved gut motility.
6. Support for Fertility and Hormonal Balance
For those trying to conceive, untreated hypothyroidism can disrupt menstrual cycles and ovulation. Proper management can restore hormonal balance and improve fertility outcomes.

We recognize that “normal” isn’t optimal
We treat the whole person, not just the thyroid
Understanding Your Thyroid: Small Gland, Enormous Impact
- Metabolism and weight
- Energy levels
- Heart rate
- Body temperature
- Mood and mental clarity
- Hair, skin, and nail health
- Digestive function
- Sleep quality
Common Thyroid Disorders
Hypothyroidism (Underactive Thyroid)
When your thyroid doesn’t produce enough hormones, your body’s processes slow down, leading to symptoms like:
- Fatigue and low energy
- Weight gain despite not eating more
- Brain fog and poor concentration
- Depression or low mood
- Cold intolerance
- Dry skin and hair loss
- Constipation
- Muscle aches and weakness
Common causes include:
- Hashimoto’s thyroiditis (autoimmune)
- Iodine deficiency
- Chronic stress
- Poor T4-to-T3 conversion
- Radiation treatment
- Certain medications
Hashimoto's Thyroiditis
This autoimmune condition is the most common cause of hypothyroidism in the United States. Your immune system attacks your thyroid, gradually destroying its ability to produce hormones.
Key facts about Hashimoto’s:
- Can be present for years before TSH becomes abnormal
- Often runs in families
- May flare up during times of stress or hormonal change
- Requires testing for thyroid antibodies for proper diagnosis
- May benefit from dietary and lifestyle changes along with medication
Hyperthyroidism (Overactive Thyroid)
When your thyroid produces too much hormone, your body’s processes speed up, causing:
- Unexplained weight loss
- Rapid or irregular heartbeat
- Anxiety, nervousness, irritability
- Excessive sweating
- Heat intolerance
- Tremors in hands
- Sleep problems
- More frequent bowel movements
Common causes include:
- Graves’ disease (autoimmune)
- Thyroid nodules
- Excessive iodine intake
- Thyroiditis (inflammation of the thyroid)
Our Comprehensive Approach to Thyroid Treatment
1. Thorough Diagnosis
Insulin resistance and blood sugar imbalances can:
- TSH, Free T4, Free T3
- Reverse T3
- Thyroid antibodies
- Nutrient testing
2. Personalized Treatment Options
Our functional medicine approach addresses thyroid health through multiple pathways tailored to your unique needs. Beyond conventional treatments, we combine targeted nutritional support, stress management techniques, environmental toxin reduction, and anti-inflammatory dietary strategies that work together to restore thyroid function.
We consider the whole person—not just lab values—and create individualized plans that address root causes while relieving symptoms. This comprehensive strategy allows us to adjust your treatment over time, adapting as your body responds and heals.

Why Standard Thyroid Testing Falls Short
Conversion Problems:
Thyroid Antibodies:
Reverse T3:
Nutrient Deficiencies:
A truly complete thyroid assessment includes:
Your thyroid may be small—just two inches across—but this butterfly-shaped gland in your neck influences nearly every cell in your body. It produces hormones that regulate your:
- TSH (Thyroid Stimulating Hormone)
- Free T4 (Inactive thyroid hormone)
- Free T3 (Active thyroid hormone)
- Reverse T3 (Blocks T3 from working)
- Thyroid Antibodies (TPO and TgAb)
- Nutrient testing (Iron/ferritin, selenium, zinc, vitamin D)
The Thyroid-Adrenal-Gut Connection
Adrenal Function
Your adrenal glands produce stress hormones that directly impact thyroid function:
- Chronic stress can block T4-to-T3 conversion.
- High cortisol can suppress thyroid function.
- Addressing adrenal health is often necessary for complete thyroid recovery.
Blood Sugar Balance
Insulin resistance and blood sugar imbalances can:
- Impair thyroid hormone conversion.
- Increase inflammation.
- Worsen thyroid symptoms.
Gut Health
Your digestive system plays a crucial role in thyroid health:
- About 20% of T4-to-T3 conversion happens in the gut.
- Leaky gut can trigger or worsen autoimmune thyroid conditions.
- Many nutrients essential for thyroid function are absorbed in the gut.

For your appointments, please note that we are an out-of-network provider. This decision allows us more flexibility in providing thorough care tailored to your needs, which often requires more time and varied treatment options than what insurance constraints allow.
If you have a PPO plan, your medical insurance may reimburse a significant portion of your visit costs. Upon request, we can provide you with a superbill for you to submit to your medical insurance for reimbursement. With an HMO plan, your visits may not be covered, but your medical insurance might cover some or all of your laboratory (lab) work expenses. If you want to use any insurance benefits, you will need to check with your insurance company to see if they will reimburse any expenses or cover labs.
Medical insurance policies now often require meeting deductibles before covering any lab costs, often requiring full payment until deductibles are met. To help manage expenses, we have negotiated lower lab prices to ease these costs for our patients and offer substantial savings on lab work costs for self-pay patients.
To understand what your medical insurance covers, contact them and inquire about your coverage for out-of-network medical providers and lab work costs. Depending on their reimbursement rates, our discounted lab program may provide you with significant savings.
We make the best treatment decisions for you, which might not always align with your insurance’s coverage. But we will work with you and do the best we can for you in this respect.
