New Research Reveals Menopause as Abrupt, Body-Wide Physiological Shift, Not Gradual Aging
A new study published in Nature Medicine, led by researchers from the Weizmann Institute of Science, challenges the long-held belief that menopause is a gradual aging process. Analyzing over 300 million laboratory test results from more than 1 million women in the United States and Israel, the study found that menopause is marked by a sudden, 'cliff-like' physiological transition across numerous bodily systems. These abrupt changes were observed in 52 out of 90 laboratory tests, affecting areas such as bone health, liver and kidney function, blood chemistry, and blood fats.
