Study redefines menopause as a physiological shift
A recent study published in Nature Medicine on October 12, 2026, describes menopause as a "physiological shift," highlighting significant biological changes around the last menstrual period. The research, based on more than 300 million laboratory tests from over a million women, uses a computational framework to analyze biological trajectories in two independent cohorts.Menopause defined by the absence of menstruation
Menopause is typically defined as the definitive cessation of menstruation, diagnosed after 12 consecutive months without menstruation, in the absence of another evident cause. Common symptoms include hot flashes, sleep disturbances, mood changes, and vaginal dryness.Biological changes extend beyond fertility
The study found that 52 of the 90 laboratory tests in the American dataset revealed a sudden and statistically significant change. These changes affect multiple systems beyond fertility, including sex hormones, bone health, liver and kidney functions, blood biochemistry, and blood lipids.Research highlights systemic impact of menopause
The findings suggest that menopause is not just a reproductive event but a complex transition involving various body systems. This insight could lead to better understanding and management of menopause-related health issues.
