%X OBJETIVO: investigar a resist¨ºncia insul¨ªnica imposta pela lipoaspira  o, correlacionando sua intensidade com a extens o da opera  o. M¨¦TODOS: A amostra foi formada de 20 pacientes do sexo feminino sem comorbidades, com idade entre 21 e 43 anos, ¨ªndice de massa corporal entre 19 e 27 Kg/m2, submetidas ¨¤ lipoaspira  o isolada ou associada ¨¤ pr¨®tese de mamas. Foram coletados os indicadores de resist¨ºncia insul¨ªnica no in¨ªcio e t¨¦rmino da cirurgia para o c¨¢lculo do Homeostasis Model Assessment (HOMA-IR). As vari¨¢veis operat¨®rias foram tempo de lipoaspira  o, tempo de pr¨®tese de mamas, ¨¢reas corporais lipoaspiradas e gordura total aspirada. RESULTADOS: O tempo de lipoaspira  o foi 94 a 278 min (m¨¦dia=174 min), tempo de pr¨®tese de mamas de 20 a 140 min (m¨¦dia=65 min), gordura total aspirada de 680 a 4280 g (m¨¦dia=1778 g). A an¨¢lise estat¨ªstica foi realizada por uma linha de corte de 1500 g de gordura aspirada e revelou uma resist¨ºncia insul¨ªnica pelo ¨ªndice de HOMA significativamente mais intensa no grupo >1500 g (aumento de 123%) em rela  o ao grupo d"1500 g (aumento de 53%,) a partir dos dados basais (p=0,02). As demais vari¨¢veis operat¨®rias n o apresentaram correla  o significativa. CONCLUS O: A resist¨ºncia insul¨ªnica apresenta aumento significativo na lipoaspira  o, correlacionada ao volume de gordura aspirado. OBJECTIVE: To investigate insulin resistance imposed by liposuction, correlating its intensity with the extent of the operation. METHODS: The sample consisted of 20 female patients without comorbidities, aged between 21 and 43 years, body mass index between 19 and 27 kg/m2, undergoing liposuction alone or associated with breasts' prosthesis. We assessed insulin resistance at the beginning and end of the procedure by calculating the Homeostasis Model Assessment (HOMA-IR). The operative variables were length of liposuction, breast prosthesis time, body areas submitted to liposuction and total fat aspirated. RESULTS: The liposuction time was 94-278 min (mean = 174 min), duration of breast prosthesis 20-140 min (mean = 65 min) and total fat aspirated 680-4280 g (mean = 1778 g). Statistical analysis was performed by considering a division line of 1500 g of aspirated fat and there was a significantly increased insulin resistance by HOMA index greater in the group > 1500 g (123% increase) than in the group d" 1500 g (an increase of 53 %) from the baseline data (p = 0.02). Other operative variables showed no significant correlation. CONCLUSION: Insulin resistance shows significant increase in liposuction, and it is correlated to the volume of aspirated fa
