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.

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.
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).
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.
Since iron, vitamin B12 and folic acid deficiencies often occur after a Roux-en-Y Gastric Bypass (RYGB), patients are advised to take daily food supplements. Based on literature and pilot studies, FitForMe developed WLS Forte in 2010, a bariatric multivitamin supplement customized to the needs of RYGB patients. In a triple-blind randomized controlled trial, the effectiveness and safety of WLS Forte was evaluated over 12 months.
A Biliopancreatic Diversion without (BPD) or with Duodenal Switch (BPD/DS) is performed relatively infrequently. The risks and benefits are still debated, since only minimal data on the long-term efficacy and safety of BPD/DS are available. To investigate the long-term effects, a retrospective cohort study was conducted among 100 BPD or BPD/DS patients.
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).
Although bariatric surgery effectively treats obesity and comorbidities, nutritional deficiencies put patients a risk of developing other health issues. Bone loss is often encountered, due to changed bone metabolism and nutrient malabsorption. Vitamin D deficiencies are common after bariatric surgery and are seen as the main cause for postoperative bone loss. However, this has not fully been investigated, nor has the efficacy of vitamin D supplementation.
Nutritional deficiencies are common after bariatric surgery. Not much is known though about deficiencies after sleeve gastrectomy (SG) in the long term. To assess the prevalence of deficiencies after SG, a prospective cohort study was conducted evaluating the nutritional status of 176 SG patients over a 5-year follow-up period.
Not much is known about the long-term nutritional impact of the Sleeve Gastrectomy procedure. In a retrospective cohort study, the nutritional deficiencies in 537 patients before and after this operation were monitored over a 5-year follow-up.
