Weight loss and nutritional anemia in patients submitted to Roux-en-Y gastric bypass on use of vitamin and mineral supplementation

Abstract

BackgroundObesity 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.AimTo analyze weight loss progression and nutritional anemia in patients submitted to Roux-en-Y gastric bypass on use of vitamin and mineral supplementation.MethodsRetrospective 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.ResultsPostoperatively, 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.ConclusionsSurgical 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.

Evaluation of systemic conditions, tooth loss, body image, and quality of life of women with obesity and women who underwent gastric bypass surgery

“…In this study, G1 had a higher prevalence of anemia ( P = .040) (Table 1). The most important causes of iron deficiency after bariatric surgery are decreased red meat consumption; decreased gastric proteases and hydrochloric acid (hypochloridria), impairing iron absorption of food; reduction of absorption surface (especially duodenum and proximal jejunum); and blood loss caused by perioperative bleeding 20 …”

“…The most important causes of iron deficiency after bariatric surgery are decreased red meat consumption; decreased gastric proteases and hydrochloric acid (hypochloridria), impairing iron absorption of food; reduction of absorption surface (especially duodenum and proximal jejunum); and blood loss caused by perioperative bleeding. 20 There was an association between tooth loss and obesity; however, due to the lack of longitudinal studies, it was impossible to understand the cause and effect relationship between these factors. 21 In addition, scientific evidence highlights the worsening of the periodontal condition after bariatric surgery, 10 which may lead to tooth loss.…”

Verification of Macro- and Micronutrient Intake in the First Year of Roux-En-Y Gastric Bypass Using MSM Method

“…This absorption is compromised by anatomical changes because of bariatric surgery. The recommendation for zinc supplementation is 50 -60 mg of elemental zinc per day [11].…”

“…Deficiencies in micronutrients postoperatively involve iron, folate, B vitamins (mainly B12), calcium, vitamin D, selenium and zinc [11].…”

Short Assessment of Mini Gastric Bypass on Weight Loss and Diabetes Volunteers Client in Sari’s Avicenna Hospital: A Preliminary Study

“…World health organization has estimated that, in 2015, 2.3 billion people will be overweight and 700 million will be obese worldwide (1). Bariatric surgery is an efficient intervention for patients with clinically severe obesity.…”
