McCall McPherson, a physician associate specializing in thyroid and metabolic health, opens the conversation with a striking claim: 80 to 90 percent of hypothyroidism cases are caused by Hashimoto’s, an autoimmune disease that can be reversed—but the resulting hypothyroidism often cannot. The distinction matters because it changes what patients should expect from treatment and how they should evaluate their options.

The Hashimoto’s vs. hypothyroidism confusion

McPherson explains that Hashimoto’s is an autoimmune condition in which the body attacks its own thyroid gland, gradually replacing hormone-secreting tissue with scar tissue. That erosion is permanent—the tissue does not grow back. So even if you put Hashimoto’s into remission (which she has done for herself, and which is measurable via antibody levels), you are often left with persistent hypothyroidism. This is why she pushes back on the popular social media promise of “reversing hypothyroidism.” What people may actually be reversing is the autoimmune attack, not the gland damage itself. The practical implication: if you have Hashimoto’s, the goal is to reduce antibodies and protect remaining tissue, not to expect a full cure.
