If you've been told your fatigue, joint pain, mood changes, brain fog, and stubborn weight are all "just perimenopause" — there's a real possibility a piece of the picture is being missed.
Hashimoto's, an autoimmune thyroid condition, peaks during the perimenopause years. It shares almost every symptom with perimenopause, which is exactly why it gets missed so often.
The Menopause Society's own clinical guide acknowledges that thyroid symptoms can be confused with menopause symptoms. The same guide notes that the causal link between estrogen decline and musculoskeletal pain is unproven. And the evidence does not support hormone therapy as a treatment for joint pain. New research from 2026 goes further — finding that MHT use in perimenopausal women may actually be associated with higher rates of tendon injuries, including shoulder and elbow tendon injuries.
This week on the blog, I'm walking through the symptoms commonly attributed to perimenopause that may actually be Hashimoto's, the one symptom that helps distinguish the two, and why the order of treatment changes everything when both are happening at once.
