A scoping review of 25 studies reports that lipedema symptom onset clusters at reproductive hormonal milestones (puberty/adolescence in 62.2-72.0% of cohorts, worsening in pregnancy in 53.0% and menopausal transition in 67.9%), with elevated hormone-sensitive comorbidities (PCOS 12.6-17.1%, autoimmune thyroiditis up to 35.5%) and molecular findings including loss-of-function variants in AKR1C1/AKR1C2, aromatase (CYP19A1) upregulation in adipose tissue, and altered estrogen receptor balance.
