What is the Origin of Perimenopausal Fat Redistribution?

This term is a clinical description based on epidemiological and body composition studies correlating hormonal changes with anthropometric measurements during the menopausal transition. The underlying cause is the loss of estrogen's protective effect on peripheral fat storage. Understanding this redistribution is vital for targeted intervention strategies aimed at mitigating cardiometabolic risk in aging women.

What is the Mechanism of Perimenopausal Fat Redistribution?

Estrogen receptors are widely distributed in adipose tissue, and estrogen typically promotes a gynoid (pear-shaped) fat distribution, which is metabolically less harmful. As estrogen levels decrease, this protective effect wanes, allowing androgens and cortisol to exert a greater influence, favoring the deposition of visceral (android, or apple-shaped) fat. This visceral fat is more metabolically active, releasing inflammatory adipokines and free fatty acids that contribute to systemic metabolic dysfunction.

Perimenopausal Fat Redistribution

Meaning

Perimenopausal fat redistribution describes the clinically observed shift in body fat storage patterns that occurs in women during the transition to menopause, characterized by a movement of adipose tissue from the hips and thighs toward the central, visceral abdominal area. This change in body composition is primarily driven by the decline and fluctuation of ovarian estrogen levels. The resulting increase in visceral fat is a critical metabolic concern, as it is strongly associated with a higher risk of cardiovascular disease and insulin resistance.
