What was done
This was a narrative review synthesizing literature on how estrogen deficiency alters adipose tissue homeostasis, lipid metabolism, and carbohydrate metabolism, with a specific focus on women with premature/primary ovarian insufficiency (POI; menopause before age 40).
What was found
The abstract reports no quantitative values or effect estimates. Qualitatively, it notes that women with POI exhibit increased visceral fat deposition, decreased lean mass, altered adipokine secretion, reduced sex hormone-binding globulin (SHBG), elevated total cholesterol, low-density lipoprotein (LDL) cholesterol, and higher triglycerides compared to age-matched controls, leading to higher risks of insulin resistance, hepatic steatosis, type 2 diabetes, and cardiovascular disease.
Why it matters
It outlines the biological mechanisms linking premature estrogen loss to early-onset cardiometabolic dysfunction, emphasizing the rationale for early interventions such as hormone replacement therapy and cardiovascular risk management in women with POI.
Limits
As a narrative review, it lacks a systematic search strategy, risk-of-bias evaluation, and meta-analytic synthesis. The abstract explicitly acknowledges that clinical evidence directly examining POI populations remains sparse, with much of the metabolic understanding extrapolated from natural menopause studies.
