A study published in Nature Medicine analysed over 300 million lab test results from one million women and revealed abrupt step-like changes in bodily health near menopause.
Researchers at the Weizmann Institute of Science identified alterations in 52 out of 90 lab tests covering skeletal, hepatic, renal, and lipid systems around the final menstrual period.
These shifts were preceded by accelerating sex hormone changes beginning over a decade prior, offering an extended window for potential preventive care.
