deficiency prevention after RYGB

A high compliance rate for regular supplements does not prevent long-term nutritional deficiencies in RYGB patients

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.

Long-term follow-up on nutritional status

In a retrospective analysis of prospectively collected data, the long-term nutritional status of 51 RYGB patients and their compliance was assessed. 35 of them used a supplement on a daily basis, for at least 6 days per week, and were as such categorized as compliant. 16 non-compliant patients were included. Regular follow-up information was collected and combined with their long-term nutritional status, determined during a follow-up visit.

Lifelong compliance for an optimal nutritional status

During the follow-up visits, deficiencies for iron, vitamin B12 and vitamin D were diagnosed in 35%, 16% and 55% of the patients respectively. Compliant use of multivitamins lowered the risk of developing iron deficiency. Furthermore, supplement compliance improved the patients’ blood values of vitamin B11, B12 and D. Because regular supplements, used by most of the compliant patients, don’t fully meet the advised dosages in the guidelines, deficiencies and hypervitaminosis were not optimally prevented.

Prevention of nutritional deficiencies

This study shows the importance of individualized, optimized food supplements and lifelong compliance, to prevent nutritional complications after bariatric surgery. Some deficiencies are only revealed years after operation, making lifelong follow-up by healthcare professionals a necessity to adequately prevent, diagnose and treat deficiencies.

Heusschen et al. found a relatively high deficiency prevalence for Gastric Sleeve patients, regardless of which type of food supplement was used. Usage of WLS Optimum resulted in higher serum values for folic acid and vitamin B1, compared to patients using a standard food supplement.

Gastric Sleeve patients benefit from specialized supplements

Smelt et al. found higher mean serum concentrations of ferritin, folic acid, vitamin B1 and vitamin D and less deficiencies in vitamin B12, ferritin, folic acid and vitamin B1 in Gastric Sleeve patients using WLS Optimum 1.0, compared to patients using standard food supplements. However, anemia was diagnosed more often in WLS Optimum users.
