To evaluate the adherence to nutritional monitoring and the evolution of the nutritional parameters of patients submitted to bariatric surgery, in consultations with the nutritionist of the multidisciplinary team of a Federal Public Hospital of Rio de Janeiro.
Methods : Retrospective study was performed in a cohort of patients submitted to gastric bypass surgery at y-roux from 2013 to 2018. The frequency of consultations and the parameters of the evolution of nutritional status (BMI,% loss total protein, albumin, vitamin 25 OH-D and vitamin B12) in the 1st year of the postoperative period, in the 1˚, 3˚, 6˚ and 12˚ months, totaling 4 consultations in this period. Descriptive statistics were calculated.
A total of 64 patients with a mean age of 43.6 ± 9.72 years were followed, with 92% (n = 59) females and 8% (n = 5) males. The BMI avarange was 47.86 ± 7.13 kg / m2. Patients' attendance at the 1-year postoperative visits was 95.5% in the first month, 86.4% in the third month, 72.7% in the sixth month, and 57.5% in the twelfth month. Each patient presented an average of 2.9 ± 0.4 visits, corresponding to 72.5% of the total proposed for this nutritional monitoring in the multidisciplinary team. When evaluated individually, a frequency of less than 75% of the scheduled appointments was observed. In relation to the nutritional status parameters: BMI and% of weight loss, it was observed in the 1st month (41.5 ± 5.7 kg / m2 and 10.8% ± 9) and 12˚ months (30 , 3 ± 5.4 kg / m2 and 0.3% ± 1.4), respectively. The biochemical parameters, the mean serum levels of total proteins, albumin, ferritin and vitamin B12 were: 1˚ (7.13 g / dl ± 0.92, 4g / dl ± 0.40, 34.9ng / ml ± 13 , 5; 552.6pg / ml ± 268.0) and 12˚ (7.07g / dl ± 0.73, 4.0g / dl ± 0.29, 31.3ng / ml ± 11.4, 309pg / ml ± 169.6).
Adherence to treatment and monitoring of the patient's nutritional evolution postoperatively is necessary to reduce possible complications, such as nutrient deficiency or body weight regain.
