Laparoscopic sleeve gastrectomy (LSG) is one of the most common surgical procedures in obesity treatment. After LSG, a lack of protein due to decreased oral intake can be seen. In our study, we investigated the effects of protein support on weight loss, muscle metabolism, and quality of life after LSG.
Materials and Methods:
Sixty-eight patients were included in the study. In the protein group, 1.2 g/kg/day protein support was given for the first month after LSG. The control group received the standard diet. Muscle volume was measured by anthropometric measurements and ultrasonography at 1 month postoperatively. Bioimpedance analysis was performed at 1, 3, and 6 months. In addition, quality of life was assessed with Short Form 36.
Results:
Free fat mass (FFM) was significantly lower in the protein group than in the control group at the preoperative and 1-month assessments (p < 0.05). Sarcopenia decreased as the protein intake approached the recommended level. Role-physical and role-emotional were significantly increased in the protein group at the sixth month (p < 0.05).
Conclusions:
We think that protein support in the first month after LSG prevents FFM loss, thus decreasing sarcopenia and improving quality of life in the long term.
