This integrative review proposes that menopause acts as a critical inflection point in lipedema progression via estrogen receptor imbalance (downregulated ERα and upregulated ERβ in affected tissue), increased local intracrine estradiol production through elevated aromatase (CYP19A1) and 17β-HSD1 with deficient 17β-HSD2, and progesterone resistance, reframing lipedema as an estrogen-dependent disorder.

• Menopause as a Critical Turning Point in Lipedema: The Estrogen Receptor Imbalance, Intracrine Estrogen, and Adipose Tissue Dysfunction Model — Pinto da Costa Viana et al. (2025) ✓ verified — consistent · narrative review · 2025 · reading confidence: high
  “No lipedema (histologia): ERα DOWNREGULADO e ERβ UPREGULADO nas regiões afetadas — alteração na sensibilidade estrogênica local confirmada [Katzer 2021]”
  The article is a narrative/integrative review that synthesizes mechanistic evidence on estrogen receptor signaling and hormonal (menopausal) influence on lipedema onset and progression, directly supporting the hormonal component of the ques [QUALITY: narrative review PROPOSING a mechanistic model (estrogen-dependency); no primary data; light peer-review venue — very low evidential weight.]

Context (PECO)

Answers these questions

• Do hormones and heredity influence the onset of lipedema? consistent
• Do hormonal factors (puberty, pregnancy, menopause, estrogen) trigger or influence lipedema onset? consistent

Gaps & caveats

Hypothesis/model paper (narrative review), not primary evidence; light-review venue. Treat as mechanistic context, not as establishing the association.
