Menopause Biomarker Shifts Are Gradual, Not Abrupt Cliff-Like Events
Challenges the menopause preprint's core assertion of sudden multi-system shifts by citing prospective cohort evidence of gradual perimenopausal change.
The VITALIS claim of an 'abrupt, multi-system physiological step change' at menopause from 300 million lab tests rests on retrospective reconstruction that cannot establish timing precision. Longitudinal data from the SWAN study (J Clin Endocrinol Metab, 2019 and 2022 follow-ups) show estradiol and FSH trajectories declining steadily across a 4–8 year perimenopausal window, with no discrete threshold jump in the majority of participants. NHANES serial cross-sections similarly document continuous, not stepwise, shifts in lipids, bone markers, and inflammatory indices. The preprint's cliff-like pattern likely reflects binning artifacts and loss of individual trajectory resolution rather than biological reality.
Women and clinicians will keep treating menopause as a years-long transition rather than a single switch, leading to earlier and more continuous monitoring instead of last-minute interventions.
