Hormones and Fat Distribution: Does Testosterone Therapy Help Older Women?
The sudden accumulation of stubborn belly fat during perimenopause and menopause rarely responds to standard caloric restriction. As ovarian follicular activity ceases, systemic circulating estradiol drops by up to 85%, alongside a gradual, steady decrease in free testosterone production. This hormonal cliff destabilizes female metabolic health, shifting how adipocytes handle circulating fatty acids.
Before menopause, estrogen directs excess calories into subcutaneous adipose tissue, primarily around the gluteofemoral region. Subcutaneous fat is metabolically stable and functions as a protective energy buffer. When estrogen plummets, lipoprotein lipase activity redirects lipid storage directly toward deep visceral depots inside the peritoneal cavity. Visceral fat wraps around the liver, pancreas, and intestines, secreting inflammatory cytokines like interleukin-6 and tumor necrosis factor-alpha. This internal shift explains why a patient's weight on the scale might increase only moderately, yet their waist-to-hip ratio and cardiovascular markers deteriorate sharply.
