Abstract

Background: Previous reports have demonstrated a significant incidence of fat-soluble vitamin deficiency after bariatric surgery. The purpose of the present study was to determine the incidence of vitamin A deficiency after Roux-en-Y gastric bypass and to correlate the laboratory findings with ocular symptoms potentially related to vitamin A deficiency. Methods: All patients who had undergone Roux-en-Y gastric bypass were invited to participate in a nutritional screening. The patients completed a detailed survey concerning ocular symptoms and had their vitamin A level evaluated. Results: A low vitamin A level was identified in 7 (11%) of 64 RYBG patients. Ocular xerosis was present in 18 patients (27%), with night vision changes reported in 45 (68%). Visual disturbances were present in 7 patients (11%) found to have low vitamin A levels, with hypovitaminosis A present in 22% of patients with xerosis (P <.05). Conclusion: Low vitamin A levels and frequent ocular complaints that might be associated with decreased vitamin A are common findings in the post-RYBG patient population. Additional study is needed to assess the role of routine vitamin A screening and replacement in the postbariatric surgery patient.
