Why I Couldn’t Lift My Arms—And What It Taught Me About Thyroid Disease

In this deeply personal episode, Dr. Laurie Marbas shares how two “frozen” shoulders became the unlikely clue to a thyroid story decades in the making. After postpartum Hashimoto’s left her on levothyroxine, a later switch to a whole‑food, plant‑based diet unexpectedly made her medication too strong—pushing her into hyperthyroidism and triggering painful adhesive capsulitis in both shoulders. Adjusting the dose thawed her shoulders and stabilized her labs, and the experience reshaped how she thinks about thyroid care.What you’ll learn* Why the thyroid is your body’s “thermostat” and how hypo vs. hyper symptoms differ* The surprising link between thyroid dysfunction and frozen shoulder (adhesive capsulitis)* How major diet shifts can change your hormone needs—and what to watch for if you’re on levothyroxine* The truth about soy and cruciferous veggies (broccoli, cauliflower) when iodine intake is adequate* The lab panel beyond TSH: free T4, total T3, and thyroid antibodies—and how “optimal” can differ from “normal”Resources* Thyroid Reset Worksheet – labs to request, optimal ranges, a food list for thyroid support, and daily healing habits.

Ask about your thyroid—and make sure you get the full picture, not just a TSH.This episode is for educational purposes and is not medical advice.
