Background/Objectives: Recompensation in patients with decompensated cirrhosis has significant prognostic implications. In this study, we aimed to evaluate the incidence and predictors of recompensation in cirrhotic patients, specifically focusing on elucidating the influence of sarcopenia and visceral obesity on achieving recompensation in a cohort of decompensated individuals. Methods: We conducted a retrospective analysis of 195 patients with decompensated cirrhosis from 2021 to 2024. Body composition abnormalities were determined by the skeletal muscle index (SMI) and visceral-to-subcutaneous adipose tissue ratio (VSR) on computed tomography (CT), respectively. Factors related to recompensation, defined using the modified Baveno VII criteria, were identified using multivariate regression. Results: Patients who achieved recompensation exhibited a lower age (62 vs. 67, p < 0.05), a higher body mass index (22.8 vs. 21, p < 0.01), a lower aspartate aminotransferase level (32 vs. 39, p < 0.01), a higher albumin level (35.2 vs. 32.3, p < 0.01), a lower ascites prevalence (60% vs. 74.07%, p < 0.05), a lower Child–Pugh score (6 vs. 7, p < 0.01), and a lower End-Stage Liver Disease score (9 vs. 10, p < 0.05) compared to those with non-recompensated cirrhosis. Body composition abnormalities were significantly more prevalent in non-recompensated patients than in recompensated patients (77.04% vs. 63.33%, p < 0.05), mainly because of a significantly higher prevalence of combined sarcopenia and visceral obesity in non-recompensated individuals (28.29% vs. 6.67%, p < 0.01). Multivariate analysis indicated that combined sarcopenia and visceral obesity was the sole independent risk factor for non-recompensation in this population. Furthermore, in the subgroup of patients aged < 70 years, with normal weight and preserved liver function, differences in recompensation rates among various states of body composition abnormalities were more pronounced. Conclusions: Sarcopenic visceral obesity is an independent risk factor for non-recompensation in patients with decompensated cirrhosis, highlighting the need for targeted interventions to mitigate body composition abnormalities in this vulnerable population.
