Abstrakt:	Aim: to study the concentration of vitamins in obese patients after bariatric surgery (BS). Material and Methods: A total of 100 obese patients aged 19 to 61 years (78 women, 22 men). 20 patients (mean body mass index (BMI)--41.3 ± 8.2 kg/m²) had adjustable gastric banding (AGB), 40 patients--sleeve gastrectomy (SG) and 40--gastric bypass (GB) (mean BMI Group 41.1 ± 17.8 kg/m², and 45.9 ± 6.2 kg/m², respectively). The control group consisted of 10 healthy subjects (BMI--24.9 ± 3.2 kg/m²). We determined the serum level of vitamins B₁, B₂, B₅, B₆, B₉, B₁₂, C, D, niacin, biotin, and retinol-binding protein (RBP) before surgery and 1 year after it. Results: There was a significant reduction ofvitamins C, B₆, B₅, D and RBP both before and after BS. More than half of patients after SG, also had initial reduction of niacin. A year after BS (AGB, SG, GB) the number of patients with deficiency of these vitamins remained the same or increased. Most patients with normal or even elevated levels ofvitamin B₂, niacin and folic acid, has been declining a year after BO. The concentration of the rest of the vitamins also significantly decreased a year after all operations, but their performance remained within normal limits. Conclusion: Levels of vitamins C, B₆ and D were reduced in more than 70% patients with obesity. The number of patients with low levels of vitamin C D, B₆, B₅, niacin, folic acid and RBP increased after BS. BS does not have a significant effect on the metabolism ofvitamins B₁, B₂, B₁₂ and biotin.
