However, data are scarce regarding the nutritional impact of this procedure on Chinese patients. This study aimed to evaluate the prevalence of nutritional deficiency after LSG in Chinese patients.Methods: Eighty-two patients with obesity were recruited from the Second Xiangya Hospital of Central South University, and all patients underwent LSG and completed the visit.Results: Compared with the baseline, the serum albumin levels increased significantly at 1– 12 months (P< 0.001) after surgery, and the hypoalbuminemia rate decreased from 8.5% to 0% throughout the study (P=0.063). Anaemia was present in 7.3% of all patients before surgery, and its prevalence increased to 11.0% at 12 months post-operation (P=0.109). The anaemia rate of fertile females was higher than that of males (21.4% vs 2.3%, P=0.036). No significant changes were found in vitamin B12 deficiency throughout the study (0% vs 3.8%, P=1.0). The increases in the folate deficiency were only discovered in the female group (3.7% vs 20%, P=0.031) and the obese without type 2 diabetes (T2D) group after LSG (27.3% vs 47.1%, P=0.031). A decrease in the ferritin levels and an increase in iron deficiency at 12 months post-surgery were found among all patients.Conclusion: Based on 12 months of follow-up, LSG is effective in controlling metabolic syndrome and has a modest effect on nutritional deficiencies, which suggests that LSG is an effective and comparably safe procedure for Chinese patients considering nutritional deficiencies at 12 months post-surgery.Keywords: anaemia, laparoscopic sleeve gastrectomy, nutrition, obesity
