Why Thyroid Treatment Isn’t Working | McCall McPherson PA-C

The medical system often reduces your thyroid—the engine of your metabolism, mood, and fertility—to a single number: TSH. In this episode, Dr. Natalie Crawford sits down with thyroid expert and Modern Thyroid Clinic founder McCall McPherson to discuss why "normal" lab ranges are leaving millions of women debilitated. McCall shares her own harrowing journey of being gaslit by the medical community while struggling to function, and together, they provide a roadmap for how you can take agency over your hormones and demand better care.

What You’ll Learn:

• The critical distinction between "crude oil" and "gasoline" hormones and why TSH testing alone fails to identify hypothyroidism in many symptomatic women.

• The surprising 10-year gap between the onset of thyroid symptoms and a formal diagnosis, and how frequent full thyroid panels can change your health trajectory.

• How subclinical hypothyroidism and Hashimoto’s disease directly impact unexplained infertility and double the risk of miscarriage during the fertility journey.

• The specific role of low dose Naltrexone (LDN), selenium, and gut health in reducing thyroid antibodies and achieving long-term autoimmune remission.

• Why conventional levothyroxine and Synthroid treatments often leave patients "stockpiling" hormones they can't use, and the importance of thyroid optimization over simple replacement.
