ABSTRACT
Background:
Roux-en-Y gastric bypass (RYGBP) has had a positive impact on co-morbidities associated with obesity. However, in the long-term it can induce micronutrient deficiencies.Aim:
To perform a complete nutritional assessment in a group of women previously operated of RYGBP, from different socioeconomic levéis (SEL). Patients andMethods:
Thirty three women (19 high SEL and 14 low SEL), were assessed by dietary recalls, anthropometric measurements, muscle strength, bone mineral density, routine clinical laboratory, serum levéis of vitamin B12, 250H-vitamin D, Mate, calcium, ferritine, ceruloplasmin and indicators ofbone turnover (parathohormone, osteocalcin and urinary pyridinolines). Their valúes were compared to those of 30 control women (18 high SEL and 12 low SEL).Results:
Low SEL operated women consumed fewer vitamin and mineral supplements compared with their high SEL pairs. No cases of vitamin B12, folie acid or copper deficiencies were detected. Frequency of iron deficieney was similar in patients and controls. Vitamin D insufficieney was higher amongpatients than in controls (p =0,04 7), regardless SEL. Patients had also a higher frequency of high serum PTH and osteocalcin and urinary pyridinoline levéis. However, no differences in bone mineral density were observed between operated women and controls.Conclusions:
Vitamin and mineral deficiencies were lower than expected among operated women. However, problems associated with vitamin D deficieney were highly prevalent among patients operated of RYGBP, irrespective SEL. These alterations were only detectable through speciñe markers at this stage, because they did not transíate into lower bone mineral density (BMD) of surgicalpatients, probably due to the higher pre-operative BMD of these morbidobese patients.Palavras-chave
