Comparing deficiency prevalences

2020-03-24T13:47:48+00:00

Deficiencies in micronutrients after bariatric operations are frequent. Theoretically, prevalence depends on the kind of surgery and which parts of the gastro-intestinal system are bypassed. In a non-randomized prospective trial, the deficiency prevalence after Roux-en-Y Gastric Bypass (RYGB, 86 patients) was compared with Sleeve Gastrectomy (SG, 50 patients) for up to 3 years after surgery. Postoperatively, all patients were prescribed daily multivitamin supplements.

Guideline on nutritional deficiencies after Roux-en-Y Gastric Bypass

2020-03-06T13:23:07+00:00

The Roux-en-Y Gastric Bypass (RYGB) is commonly associated with nutritional deficiencies and requires life-long supplementation. To bring guidance into nutritional healthcare for this patient group, a literature review was conducted. This review lead to a guideline on the approach to prevention and management of nutritional deficiencies after RYGB.

Deficiencies after Biliopancreatic Diversion

2020-01-23T09:28:15+00:00

Worldwide use of the Biliopancreatic Diversion (BPD) as a bariatric procedure to treat obesity is still limited due to its relative technical difficulty and demanding follow-up. However, BPD achieves better results than other bariatric operations in the long term of 10-15 years. This study extends the long-term results with another 5 years and reports the 20-year outcomes of 2615 patients undergoing open BPD with Duodenal Switch (DS).

Iodine absorption after bariatric surgery

2020-01-06T15:12:27+00:00

Bariatric surgery is often accompanied by malnutrition of several vitamins, minerals and trace elements. Iodine is a trace element, needed for synthesis of thyroid hormones. Since iodine is absorbed from the intestinal tract, patients after bariatric surgery are hypothetically at risk of malabsorption. This study aimed to estimate the daily absorption of iodine for patients after bariatric surgery in which several parts of intestine were bypassed.

Revisional procedures after Sleeve Gastrectomy

2020-03-23T07:26:15+00:00

For a long time, professionals have stated that a Sleeve Gastrectomy (SG) procedure has minimal impact on the nutrient status. However, studies have found that deficiencies are as common in SG patients as in Roux-en-Y Gastric Bypass patients. To prevent vitamin and mineral deficiencies after an SG, lifelong supplementation is recommended. In 2009, FitForMe developed a specialized multivitamin supplement specifically for SG patients, based on scientific research: The first version of WLS Optimum.

Sleeve Gastrectomy patients benefit from specialized multivitamins

2020-01-06T12:31:15+00:00

To prevent vitamin and mineral deficiencies after a Sleeve Gastrectomy (SG), lifelong supplementation is recommended. However, standard multivitamin supplements (sMVS) are proven to be ineffective in the prevention of nutritional deficiencies. Therefore, FitForMe developed WLS Optimum, specifically for SG patients. In a retrospective analysis including 970 SG patients, the effectiveness of WLS Optimum on deficiencies was compared to a standard multivitamin for a period of five years.

Timing of pregnancy after bariatric surgery: preliminary results

2019-12-09T14:46:35+00:00

Current recommendations indicate to avoid pregnancy 12 to 18 months postoperatively due to active weight loss and increased risk of nutritional deficiencies. However, no high-quality evidence supports this recommendation. A study was conducted to examine the association between surgery-to-conception interval and pregnancy and neonatal complications, gestational weight gain and nutritional status.

Long-term supplementation after a Sleeve Gastrectomy

2019-12-09T14:47:39+00:00

The Sleeve Gastrectomy (SG) has become the most frequently performed bariatric procedure worldwide. Patients undergoing an SG are at risk for developing micronutrient deficiencies in the short term after surgery, due to limited oral intake, food intolerances and malabsorption. To assess their long-term nutritional status, a retrospective study was conducted collecting data of the nutritional status of 1793 SG patients over a 5-year follow-up period.
