Abstract

Background: Nutritional deficiencies have been reported in bariatric surgery patients with inconsistent results. However, scarce data exist for Chinese patients. We aimed to assess nutritional deficiencies in Chinese patients undergoing Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), and to identify predictors of postoperative nutritional status.

Methods: A retrospective review of a prospectively collected database was conducted in the patients undergoing RYGB and SG in our hospital between June 2013 and January 2017. Anthropometric data and nutritional data were collected before surgery, at 6 and 12 months postoperatively.

Results: This study enrolled 269 patients (120 RYGB, 149 SG). Nutritional deficiencies were common in Chinese bariatric candidates, with vitamin D deficiency the most serious (78.8%), followed by vitamin B1 (39.2%), vitamin B6 (28.0%), folate (26.8%), vitamin C (18.0%) albumin (13.4%), transferrin (11.6%), and phosphorus (11.5%). Despite postoperative routine multivitamin and calcium supplements, nutritional deficiencies were still obvious for RYGB and SG patients. The prevalence of hemoglobin and vitamin B12 deficiencies increased remarkably in the RYGB group; the levels of hemoglobin, globin, vitamin B12, and ferritin decreased significantly (P < 0.05). Preoperative hemoglobin, vitamin B12, and ferritin levels were independently associated with postoperative decrease, respectively. Deficiencies of vitamin D, vitamin B1, vitamin B6, vitamin C, and albumin before surgery were predictors for deficiencies 1 year after surgery, respectively.

Conclusion: Nutritional deficiencies are common in Chinese bariatric surgery candidates. Similar deficiencies were also seen after RYGB and SG. Routine evaluation and related corrections of preoperative nutritional abnormity could contribute to postoperative nutrient balance.
