Recognise the Signs
Common Symptoms
These symptoms are often dismissed as 'normal aging' — but they're not. They're signs your thyroid needs deeper investigation.
Chronic Fatigue
Persistent exhaustion that doesn't improve with rest, often worse in the afternoon despite adequate sleep.
Unexplained Weight Gain
Gaining weight despite eating well and exercising, or inability to lose weight no matter what you try.
Hair Loss & Thinning
Diffuse hair loss, thinning eyebrows (especially the outer third), and brittle, dry hair texture.
Brain Fog & Memory Issues
Difficulty concentrating, mental sluggishness, word-finding problems, and poor short-term memory.
Depression & Anxiety
Low mood, irritability, and anxiety that don't respond well to conventional antidepressants.
Cold Intolerance
Feeling cold when others are comfortable, cold hands and feet, and difficulty regulating body temperature.
Beyond the Surface
Root Causes We Investigate
Autoimmune Thyroiditis (Hashimoto's)
Over 90% of hypothyroidism in the US is autoimmune. Standard TSH tests miss the antibodies that reveal Hashimoto's years before TSH becomes abnormal.
Nutrient Deficiencies
Iodine, selenium, zinc, iron, and vitamin D are all essential for thyroid hormone production and conversion. Deficiencies are extremely common and rarely tested.
Gut Dysbiosis & Intestinal Permeability
20% of T4-to-T3 conversion happens in the gut. Leaky gut triggers molecular mimicry that can initiate and perpetuate thyroid autoimmunity.
Chronic Stress & Cortisol Dysregulation
Elevated cortisol inhibits TSH secretion, blocks T4-to-T3 conversion, and increases reverse T3 — creating 'functional hypothyroidism' with normal labs.
Environmental Toxins
Heavy metals (mercury, lead), pesticides, BPA, and fluoride are documented thyroid disruptors that interfere with hormone synthesis and receptor binding.
Blood Sugar Imbalances
Insulin resistance and reactive hypoglycemia create inflammatory cascades that suppress thyroid function and worsen autoimmune flares.
Our Process
The Functional Medicine Approach
We go far beyond TSH. Our comprehensive thyroid investigation gives you the complete picture — and a clear path forward.
Complete Thyroid Panel
We run TSH, Free T4, Free T3, Reverse T3, TPO antibodies, thyroglobulin antibodies, and thyroid ultrasound when indicated — not just the TSH your PCP ordered.
Root-Cause Investigation
We assess gut health (GI-MAP), nutrient status, adrenal function (DUTCH test), inflammatory markers, and environmental toxin exposure to find what's driving your thyroid dysfunction.
Personalized Protocol
Based on your results, we design a targeted protocol that may include dietary modifications, targeted supplementation, stress management strategies, and toxin reduction.
Ongoing Optimization
We retest at 90-day intervals, adjusting your protocol based on objective lab improvements and how you feel. The goal is optimal function, not just 'normal range.'
Patient Stories
Real Results, Real People
"I was told my thyroid was 'fine' for 8 years while I gained 40 pounds and lost half my hair. Dr. Crifase found Hashimoto's on the first visit and within 6 months I felt like a different person."
Sarah M.
Hashimoto's thyroiditis, age 42
"My endocrinologist only tested TSH. Dr. Crifase ran a full panel and found my Free T3 was tanked and my reverse T3 was sky-high. Addressing the root causes changed everything."
Jennifer K.
Hypothyroidism, age 38
