Based on currently indexed evidence, both hormones and heredity appear to influence lipedema onset, though the evidence base is predominantly low-to-very-low quality (consensus documents, narrative/systematic/scoping reviews, cross-sectional surveys, GWAS, and case reports), supporting them as contributors rather than proven sole causes. For HORMONAL influence: converging evidence from a 2025 consensus (hormonal triggers/exacerbation rated 4.46), multiple reviews, and cross-sectional surveys consistently reports onset/worsening clustering at female hormonal transitions—puberty (commonly 15.7–72.0%; e.g., 49% perceived trigger in a Saudi cohort, 55% puberty onset in a 67-proband series, mean onset 16±9 in a 209-patient survey), pregnancy/lactation (9.5–63.1%; ~53% worsening), and menopause (~1.9–21% onset, with ~67–67.9% reporting exacerbation)—plus near-exclusive female occurrence (~11% of women) and elevated hormone-sensitive comorbidities (PCOS ~12.6–17.1%, menstrual irregularities ~43%, autoimmune thyroiditis up to 35.5%). A moderate-quality cross-sectional study found 58.8% of hormonal contraceptive users reporting symptom worsening (χ²=213.71, p<0.001; 15.1% reporting onset coinciding with initiation), with acknowledged recall/selection bias. Mechanistic reviews consistently propose tissue-level estrogen dysregulation—an altered ERα/ERβ ratio (reduced ERα, increased ERβ, plus GPER involvement) in gluteofemoral adipose tissue, increased local intracrine estradiol via aromatase (CYP19A1)/17β-HSD enzymes, progesterone resistance, and estrogen effects on ZNF423/PPAR-γ2 in adipose stem cells—reframing lipedema as an estrogen-regulated/estrogen-dependent disorder. A moderate-quality systematic review reinforces that hormonal dysregulation (estrogen metabolism/receptor function, growth-hormone imbalance, adipokine/leptin-related adipose stem cell alterations) underlies four distinct pathophysiological hypotheses, with possible genetic susceptibility. For HEREDITY: multiple reviews and surveys report frequent positive family history (commonly 15–89% across studies, predominantly female first-degree relatives) with patterns most consistent with autosomal dominant inheritance with incomplete penetrance and sex-limited/female-preferential expression; X-linked dominant inheritance was explicitly excluded by linkage analysis (lod < -2) in the largest studied family. Genetic studies have progressed from candidate genes (305 genes via NGS in 162 patients) to genome-wide data: a moderate-quality UK Biobank phenotype GWAS identified ~18 loci (SNP heritability ~5.13%) including RSPO3 (OR=1.24), VEGFA, GRB14-COBLL1, and ADAMTS9, with genetic correlations to body fat, leptin, and age at menopause; a dedicated UK cohort GWAS (n=130) flagged a suggestive replicated locus near LHFPL6; and family-based sequencing (31 individuals, 9 families) supports polygenic heterogeneity (variants across 469 genes, no single Mendelian cause, enrichment in vasopressin-receptor pathways). Rare monogenic findings link hormone-metabolism genes—notably AKR1C1/AKR1C enzymes (progesterone/steroid metabolism), with the AKR1C1 c.638T>A (p.L213Q) variant segregating with disease across an autosomal-dominant family (3 affected with puberty onset, absent in 9 unaffected) and predicted to cause partial loss of 20α-HSD function—plus AKR1C2 Ser320PheTer2, regulatory polymorphisms (rs28571848/rs34477787), and POU1F1A/PIT1 and NSD1 (GH/PRL/TSH; androgen/estrogen-mediated tissue expansion), offering biological convergence between hereditary and hormonal pathways. IMPORTANTLY, the single highest-quality source—a PRISMA-based systematic review/meta-analysis (rid: DOI 10.1055/a-2183-7414, graded high)—found NO significant difference in circulating testosterone or estradiol between patients and controls, indicating systemic sex-hormone concentrations alone do not explain the condition and pointing instead to tissue-level receptor and metabolic mechanisms; this high-quality finding constrains the hormonal claim to local/tissue-level rather than systemic dysregulation.

A systematic review of lipedema pathology found that testosterone and estradiol showed no significant difference versus controls in plasma analysis, while the condition almost exclusively affects females and its fundamental etiology remains largely uncertain despite growing molecular and histological research.

Major uncertainty
Causation and direction remain unproven: nearly all evidence is descriptive, cross-sectional, or mechanistic/hypothesis-generating (very-low to low grade), with the only high-quality source (a PRISMA meta-analysis) finding NO systemic sex-hormone difference vs controls—so hormonal influence is constrained to unproven tissue-level receptor/metabolic mechanisms rather than systemic hormone excess. Onset-timing and family-history data rely heavily on self-report (recall/selection bias) and lack longitudinal/prospective confirmation. Genetics is polygenic and heterogeneous with no single Mendelian cause; GWAS loci reach only modest heritability (~5%) and several signals are merely suggestive or unreplicated, while rare monogenic variants (AKR1C1) derive from single families and have not been broadly validated. The inheritance pattern (autosomal dominant with incomplete penetrance/sex-limitation) is inferred, not established. No interventional or causal study confirms that modifying hormones alters lipedema onset.
