tive dumping was not different between RYGB and SG.
Recent data showed that late dumping scores increased
gradually with time up to 12 months after SG, as well as
hypoglycaemia [21]. Further data report postprandial
hyperinsulinemic hypoglycaemia in some cases up to 2
years after surgery [22]. Therefore, it is possible that
other long-term complications can occur, but are not
emphasized in our analysis, as our data were collected
for one year following the bariatric surgery.
5. Conclusion
Against common assumptions, vitamin and iron deficien-
cies in SG patients are not less frequent in the first post-
surgical year in comparison to RYGB patients. Standard
supplementations should include iron in premenopausal
women: Vitamin D at least 1000 IU per day and vitamin
B12 i.m. administration in case of a deficiency. Regular
oral intakes of vitamin B1 and B6 in addition to routine
multi-vitamin supplementations were found to be inef-
fective in preventing vitamin deficiencies.
