Bariatric patients should undergo continuous vitamin B12 replacement, as well as adequate monitoring by health professionals in the preoperative period, in the immediate postoperative period and throughout life. The objective of this research was to analyze the self-knowledge of patients who underwent bariatric surgery, regarding vitamin B12 deficiency, its symptoms and nutritional education regarding replacement. In methodological terms, this is a research with a quantitative approach, with a cross-sectional nature, in which bariatric patients filled out a questionnaire via Google Forms, on questions related to the proposed objective. From the data collected, a description of the studied sample was carried out, in which it was observed that this was composed mostly of women, with the majority in the age group of 42 to 49 years. In the postoperative period of bariatric surgery, 68% had vitamin B12 deficiency, considering the vitamin deficiency in the first moment. Already 24% reported memory loss and 22% reported frequent fatigue and weakness. As for vitamin B12 replacement, 42% were instructed to replace it orally and 34% did it intramuscularly, but about 36% of the study sample reported not following the recommended replacement. In short, bariatic patients are self-aware of vitamin B12 deficiency and the symptoms of this absence in the body. Furthermore, these individuals begin treatment with replacement, but report not continuing with this follow-up, making it necessary to provide further guidance from professionals related to bariatric surgery in view of the importance of this follow-up being carried out periodically, in order to properly instruct these individuals regarding their food and nutrition education.
