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.

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.

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.

RYGB patients benefit from specialized multivitamins

2019-12-09T14:49:50+00:00

After a Roux-en-Y gastric bypass (RYGB), patients are advised to take lifelong supplementation to reduce the risk of developing deficiencies. Standard multivitamin supplements (sMVS) are proven to be ineffective to restore deficiencies in the long term. To adjust to the needs of RYGB patients, a specialized bariatric multivitamin supplement (WLS Forte) was developed in 2010. Earlier studies in a smaller group of patients concluded that use of this WLS Forte results in significantly less postoperative deficiencies after 1 and 3 years. The objective in this study was to examine the efficacy of WLS Forte in a bigger population in the long term.

Iron deficiency prevention after RYGB

2020-01-06T08:06:48+00:00

The choice of approach to prevent iron deficiency after RYGB Iron deficiency is very common after Roux-en-Y Gastric Bypass (RYGB). Despite the standard prescription of iron supplements post-RYGB, the optimal approach to prevent iron deficiency, or the differences in absorption rate between various supplements, have not yet been evaluated. Iron absorption: tablet versus solution To assess the differences in iron absorption between a full tablet form and a solution form, twenty-four female patients were included. 1 week before and 1 month after RYGB, twelve patients received a single dose of 600 mg ferrous fumarate in [...]

Compliance for long-term deficiency prevention

2019-12-09T15:07:02+00:00

Lots of studies have been done on deficiencies and the efficacy of supplementation after RYGB. Most studies have a limited follow-up period. However, some deficiencies may be revealed only many years after surgery, and supplementation compliance is known to drop over time.

The efficacy of vitamin B12 supplementation methods

2020-01-06T08:11:38+00:00

Vitamin B12 deficiencies are very common among obese and Roux-en-Y Gastric Bypass (RYGB) patients. Conventional treatment includes regular intramuscular vitamin B12 injections. The objective in this study was to investigate whether oral supplementation increases and normalizes low vitamin B12 concentrations in RYGB patients as compared to intramuscular injections.

Iron and calcium supplementation after Roux-en-Y Gastric Bypass

2019-12-09T15:10:15+00:00

To prevent vitamin and mineral deficiencies after malabsorptive and restrictive bariatric surgery, lifelong nutritional supplementation is recommended. However, since several tablets have to be taken separately and scheduled in time to avoid potentially competitive absorption of iron and calcium, compliance is difficult. A retrospective study was conducted to determine whether a combined multivitamin supplement with both iron and calcium still prevents deficiencies in patients after a Roux-en-Y Gastric Bypass (RYGB).

Long-term effect of WLS Forte for RYGB patients

2020-01-06T12:33:15+00:00

After a Roux-en-Y Gastric Bypass (RYGB), patients are advised to take lifelong food supplements to reduce the risk of developing deficiencies. To adjust to the specific needs of RYGB patients, a specialized bariatric multivitamin supplement (WLS Forte) was developed in 2010. A previous study has shown the efficacy of WLS Forte on the nutritional status of RYGB patients in the first year after surgery: iron deficiencies were lowered by 88% when using WLS Forte. The present study builds on the initial evidence by evaluating the longer-term effects and safety of WLS Forte, 3 years after RYGB.
