Food intake recall and biochemical and anthropometric measurements were used to determine protein, iron, and folate nutritional status of 12 patients before and four months after gastric bypass surgery. Post-surgery intake of the nutrients was significantly lower than the Recommended Dietary Allowances. Highest levels of serum folate were observed after surgery, while serum iron levels showed no significant changes. Deficit protein intake, very low creatinine-height index, and significant changes in anthropometrics all indicated the loss of body mass. Serum transferrin levels did not differ significantly, suggesting visceral proteins were intact.
通过食物摄入量回忆以及生化和人体测量学指标，来确定12名患者在胃旁路手术前及术后四个月的蛋白质、铁和叶酸营养状况。术后这些营养素的摄入量显著低于推荐膳食摄入量。术后血清叶酸水平最高，而血清铁水平无显著变化。蛋白质摄入不足、极低的肌酐身高指数以及人体测量学指标的显著变化均表明体重减轻。血清转铁蛋白水平无显著差异，提示内脏蛋白完好无损。
