Background: Folate deficiency bariatric procedures that can contribute to anemia. The prevalence of this deficit after both restrictive and malabsorptive procedures ranges from 9% to 39% in the literature. Our aim was to interrogate the Clinical Practice Research Datalink (CPRD) for folate recordings in this surgical cohort. Method: All patients captured within the CPRD that had Bariatric surgery episodes were interrogated to assess folate level measurements using SPSS 25. Results: There were a total of 6,601 recorded folate measurements for 4414 patients in the bariatric surgery group within the CPRD. There were 1,710(25.9%) recordings pre-operatively and 4,891(74.1%) postoperatively. 31.9% had recordings pre and post-operatively. Readings ranged from 1 to 23 (4.22,SD 4.32) and 1 to 46 (5.87,SD 6.20) post-operatively. Folate was low in 173(10.1%) patients and high in 81 (4.7%) patients prior, while 408(8.3%) and 475 (9.7%) after surgery respectively. Bariatric surgery had a significant effect on the difference of low (p=0.029) and high (p
