This review proposes that dysregulated estrogen signaling in adipose tissue—via an increased ERα/ERβ ratio in gluteofemoral adipocytes or excessive local paracrine estrogen production by adipocyte steroidogenic enzymes—drives the excessive subcutaneous fat accumulation in lipedema, and cites whole-exome sequencing linking lipedema to variants in sex hormone genes, with onset coinciding with hormonal fluctuation periods such as puberty, pregnancy, and menopause.

- Lipedema and the Potential Role of Estrogen in Excessive Adipose Tissue Accumulation — Katzer et al. (2021) ✓ verified — consistent · review · 2021 · reading confidence: high
“The onset of lipedema pathophysiology is thought to occur during periods of hormonal fluctuation, such as puberty, pregnancy, or menopause.”
Narrative/mechanistic review proposing hormonal (estrogen receptor) and genetic bases for lipedema onset, directly addressing both hormonal influence and heredity; supports the affirmative direction but is hypothesis-generating with no orig [grade capped low->very_low per curated Oxford N6]
Context (PECO)
Answers these questions
- Do hormones and heredity influence the onset of lipedema? consistent
- What specific genetic variants or inheritance patterns have been identified in lipedema? contextual
- Do hormonal factors (puberty, pregnancy, menopause, estrogen) trigger or influence lipedema onset? consistent
- Is lipedema onset influenced by heredity and family history? consistent
