Obesity is a chronic disease with high growth in population and bariatric surgery is currently considered the most effective treatment for weight reduction; on the other hand, nutritional deficiencies are observed after this procedure.
To analyze weight loss progression and nutritional anemia in patients submitted to Roux-en-Y gastric bypass on use of vitamin and mineral supplementation.
Retrospective analysis of 137 patients of both sexes, aged between 18-60 years, using supplemental multivitamins and minerals, were included; personal information, anthropometric and laboratory data in the preoperative, 12, 24, 36 and 48 months postoperatively were collected.
Postoperatively, in both sexes, occurred weight loss compared to the pre-operative weight gain at 48 months and maintenance of body mass index. There was a decrease in the percentage of excess weight loss at 48 months postoperatively compared to the time of 12, 24 and 36 months in men and decreased at 48 postoperative months compared to the time of 24 months in females. There was a decreased in serum ferritin in both sexes and increased serum iron at 48 months postoperatively in males. There was a decreased in vitamin B12 and folic acid increased serum at 48 postoperative months in females.
Surgical treatment was effective for reducing weight, body mass index reduction and achievement of success in the late postoperative period along with multivitamin and mineral supplementation on prevention of serious nutritional deficiencies and anemia.
肥胖是一种发病率不断攀升的慢性疾病，目前减肥手术被认为是最有效的减重治疗方法；另一方面，该手术后会出现营养缺乏的情况。
分析接受 Roux-en-Y 胃旁路手术的患者在使用维生素和矿物质补充剂后的体重减轻进程及营养性贫血情况。
对 137 例年龄在 18 - 60 岁之间、使用复合维生素和矿物质补充剂的男女患者进行回顾性分析；收集术前、术后 12、24、36 和 48 个月的个人信息、人体测量数据和实验室数据。
术后，男女患者体重均较术前增加，48 个月时体重减轻且维持了体重指数。与术后 12、24 和 36 个月相比，男性患者术后 48 个月的超重减轻百分比下降，女性患者术后 48 个月与术后 24 个月相比超重减轻百分比下降。术后 48 个月时，男女患者血清铁蛋白均下降，男性患者血清铁升高。术后 48 个月时，女性患者维生素 B12 下降，血清叶酸升高。
手术治疗在减轻体重、降低体重指数以及术后晚期取得成功方面是有效的，同时复合维生素和矿物质补充剂可预防严重的营养缺乏和贫血。
