How does lipedema relate to varicose veins and venous disease?
Based on currently indexed evidence, lipedema and varicose veins frequently coexist: a cross-sectional study found 45.1% of lipedema patients had varicose veins, and two case reports from India documented bilateral varicose veins in both lipedema patients presented. However, a moderate-grade cross-sectional study found that lipedema patients show elevated serum VEGF-C and increased M2/CD163+ macrophage infiltration without corresponding morphological changes in lymphatic or blood vessels, suggesting that while varicose veins co-occur clinically, lipedema does not appear to produce overt structural venous disease through its molecular vascular changes. A National Inpatient Sample analysis also examined venous thromboembolic outcomes in patients with lymphedema and lipedema, though findings from that study remain unclassified in the current evidence base. Overall, the venous ultrasound examination performed for varicose veins represents a potential opportunity for lipedema screening, but the mechanistic relationship between lipedema and venous disease remains incompletely understood. Evidence quality is low to very low for the co-occurrence data, with the vascular biology findings graded moderate.

What changed in this version
This update added two case reports documenting bilateral varicose veins in lipedema patients, a moderate-grade vascular biology study showing no morphological blood vessel changes despite elevated VEGF-C in lipedema (refining the mechanistic picture), and a National Inpatient Sample study on venous thromboembolic outcomes in lipedema/lymphedema patients (currently unclassified), collectively deepening but also complicating the understanding of the lipedema–venous disease relationship.

Because ~49% of women have varicose veins and ~11% have lipedema, a substantial proportion of women undergoing venous ultrasound for varicose veins also have coexisting lipedema, making the venous exam an opportunity for lipedema screening.

Both reported lipedema cases presented with bilateral varicose veins alongside characteristic disproportionate subcutaneous fat distribution, consistent with a described association between lipedema and varicose veins in the literature.

Lipedema patients show elevated serum VEGF-C and increased macrophage infiltration (predominantly M2/CD163+) without corresponding morphological changes in lymphatic or blood vessels, distinguishing lipedema from lymphedema and suggesting the vascular changes do not produce clinical lymphedema or overt venous disease.

Major uncertainty
The causal or mechanistic relationship between lipedema and varicose veins remains unclear. It is unknown whether shared risk factors (e.g., female sex, obesity, connective tissue laxity) explain co-occurrence, or whether lipedema pathophysiology directly contributes to venous insufficiency. The venous thromboembolic risk in lipedema patients is also uncharacterized from the indexed evidence. Existing co-occurrence data derive from a single vascular-clinic sample and very small case series, limiting generalizability.
