Name: What “you’re a little young for that” actually means.
Creator: Dr. Maya Okonkwo

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.

Key takeaways so far

01Perimenopause usually starts 4–8 years before the final menstrual period, placing onset for many women squarely in their 40s, with a substantial minority beginning in the early 40s.
02Telling a woman in her early-to-mid 40s that she is "a little young" for perimenopause is not supported by SWAN data and often reflects a training gap rather than a clinical assessment.
03A proper workup for perimenopausal-type symptoms in the early 40s should include thyroid function tests (TSH ± free T4 and anti-TPO), CBC with ferritin to assess for iron-deficiency anaemia, and consideration of PCOS, functional hypothalamic amenorrhoea, and—if under 40 or with markedly elevated FSH—premature ovarian insufficiency.
04Racial and ethnic differences in onset and symptom duration are well documented: African American and Hispanic women tend to experience vasomotor symptoms earlier and for longer than white women, so age-based dismissal can be especially misleading for women of colour.
05FSH fluctuates widely in perimenopause, so a single normal FSH does not rule it out; major guidelines (e.g., NAMS, Endocrine Society) support diagnosis based primarily on age, cycle pattern, and symptoms rather than one lab value.
