This piece explains that perimenopause commonly begins in the 40s (and not just the late 40s or 50s), that age-based dismissal often replaces proper clinical workup, and that onset and symptom patterns vary significantly by race and ethnicity. It also offers concrete language patients can use to push back when their concerns are minimized, and highlights the importance of ruling out thyroid disease, iron-deficiency anaemia, PCOS, functional hypothalamic amenorrhoea, and especially premature ovarian insufficiency (POI) in younger women.
