  "current_answer": "A clinical cohort reported a higher prevalence of celiac-associated HLA-DQ2/DQ8 haplotypes in lipedema, and population (NHANES) analyses found lower gynoid fat in celiac women and an unusual food-IgG pattern. These are single cross-sectional analyses with small case numbers and no demonstrated causal mechanism.",
  "current_answer_pt": "Uma coorte clínica relatou maior prevalência dos haplótipos HLA-DQ2/DQ8 associados à doença celíaca no lipedema, e análises populacionais (NHANES) encontraram menor gordura ginoide em mulheres celíacas e um padrão incomum de IgG alimentar. São análises transversais isoladas, com pequeno número de casos e sem mecanismo causal demonstrado.",
  "major_uncertainty": "No concurrent controls, small celiac case counts, reverse causation not excluded; mechanism unproven.",
