Evidence (1)
- Lipedema in patients after bariatric surgery — Bast et al. (2016) ✓ verified — conflicting · case series · 2016 · reading confidence: high
“Ambos os casos demonstram resistência da gordura lipedematosa à perda de peso por cirurgia bariátrica, confirmando a não-responsividade ao déficit calórico como critério diagnóstico central”
Two case reports directly addressing whether bariatric-induced weight loss alters lipedema fat; both show persistence of lipedema fat despite significant weight loss, contradicting the affirmative that weight loss reduces lipedema fat volum
