Research Article



Based on the reduced gastric volume and the malabsorption produced by Roux-en-Y gastric bypass (RYGBP) and diet therapy, it is essential in the postoperative period to obtain and maintain an adequate nutritional state, with the aim of preventing malnutrition and seeking a healthy life. It is observed that patients have difficulty in understanding the new food choices that must considered, as they have eating habits that are very divergent from those currently proposed. There is often the need for vitamin and mineral replacement after laboratory tests.


This study calculated and evaluated the 24-h eating records of 210 patients, collected in the course of nutritional visits in follow-ups of the first, third, sixth, ninth, 12th, 18th, and 24th months postoperative.


It was possible to observe an increase in the consumption of nutrients in the course of the study period, but it was not regular and significant for all the nutrients. Also, it is noted that the minimal requirements for vitamin A, vitamin C, calcium, iron and B-complex vitamins (except for cyanocobalamin and riboflavin) were not attained. The nutrients in which satisfactory results were obtained were total proteins of high biological value: cyanocobalamin and riboflavin.


This study demonstrated the concern for nutrient supplementation in the postoperative period of RYGBP. Thus, the routine use of multivitamins is deemed necessary after the first month postoperatively, with its maintenance preferably for the rest of the patient’s life, without abandoning periodic clinical and laboratory follow-up.
