Experts: 'Nature Medicine' Study on Abrupt Menopausal Shift

Neptune, N.J. - October 14, 2026 - A new study published in Nature Medicine is shattering the long-held perception that menopause is primarily a gradual reproductive transition characterized by the end of menstruation. According to the research, the loss of sex hormones triggers an abrupt, systemic biological shift that not only impacts a woman's reproductive system but also alters a woman's blood chemistry, lipid levels, liver and kidney function, as well as bone health.

Study authors developed a method to obtain a cross-section of menopause dynamics from two large medical datasets. The method was applied to more than 300 million laboratory tests from more than one million women. Approximately two decades of data examining menopausal-aged women who were prescribed menopause hormone therapy (MHT) or self reported MHT were used.
