Low thyroid function is one of the most commonly missed diagnoses in conventional medicine — often dismissed when standard labs fall within "normal range."
Standard TSH testing has a wide "normal" range that can overlook meaningful dysfunction. Many patients with clear symptoms are told their labs are fine.
Dr. Kellman uses a highly precise thyroid test to detect low thyroid function more definitively — a test often unknown and underutilized elsewhere — combined with the gut-thyroid connection central to Microbiome Medicine.
Thyroid issues are most often caused by autoimmune attack (Hashimoto's disease), nutrient deficiencies, chronic stress, and gut microbiome imbalance, which can impair thyroid hormone conversion and regulation.
Common signs include persistent fatigue, weight gain resistant to diet and exercise, brain fog, hair thinning, cold intolerance, and low mood.
Standard TSH testing has a wide reference range that can miss meaningful dysfunction. More precise, comprehensive thyroid testing can reveal issues standard bloodwork overlooks.
Treatment may include bio-identical thyroid hormone therapy, addressing gut microbiome imbalance, and targeted nutrients — personalized to the root cause identified through advanced testing.
