Comparative study of the nutritional status of vitamin A in pregnant women and in women who became pregnant or did not after Roux-en-Y gastric bypass
Abstract Introduction: the changes in digestive physiology after Roux-en-Y gastric bypass (RYGB), as well as pregnancy, maximizes the risk of vitamin A deficiency (VAD) and both can result in harm to the mother and child health. Objective: to compare the nutritional status of vitamin A among women who became pregnant or did not after RYGB and in pregnant women who did not undergo surgery, and to assess the impact of VAD on the mother and child health. Methods: this is a cross-sectional study of the analytical type. The women were divided into: group 1 (G1) with 80 pregnant women; group 2 (G2) with 40 pregnant women who had previously undergone RYGB, both in their third trimester of pregnancy; and group 3 (G3) with 77 non-pregnant women who had previously undergone RYGB. Serum concentrations of retinol and β-carotene, night blindness (NB), gestational and neonatal intercurrences were investigated. The significance level adopted was p < 0.05. Results: RYGB, per se, had a greater impact on the inadequacy of retinol, β-carotene, and on the increased percentage of NB when compared to non-surgical pregnant women. When surgery was associated with pregnancy, more than 75% of inadequacy of retinol and β-carotene was noted, as well as a higher percentage of individuals with NB. G2 also showed increased prevalence ratio for developing gestational and neonatal intercurrences, when compared to G1. Conclusion: RYGB provides greater negative impact on the nutritional status of vitamin A compared to pregnancy, and surgery associated with pregnancy can create even greater risks.
