Abstract

Background and Aims

Bariatric surgery is considered to be the most effective treatment of morbid obesity. Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGBP) are the most popular procedures. We evaluated nutritional status, micro- and macronutrient intake, and oral hydration in patients before and regularly during 1 year after RYGBP and SG.

Methods

All patients that had been through bariatric surgery with at least 1-year post-surgery were retrospectively included in the study. All participants were evaluated once during the 2 months before the surgery and at 1, 3, 6, and 12 months after surgery. Clinical and biological evaluations as well as dietary investigations were performed.

Results

Fifty-seven patients were included in this study (28 RYGBP and 29 SG). Patients in the RYGBP group had significantly higher body weight (132.3 ± 22 versus 122.2 ± 22.2 kg, p = 0.039) than patients in the SG group. Before surgery, total energy intake, oral hydration, and vitamin and mineral intakes were not different between the two groups. RYGBP and SG induced significant similar excess weight loss 1 year after surgery, 48.6 29.8% and 57.6 27.6% of body weight respectively. Energy intake significantly decreased 1 month after surgery and slightly increased from 1 to 12 months without reaching baseline intake levels. Macronutrient repartition did not change during follow-up. Oral hydration significantly decreased after RYGBP (− 58%) and showed a trend to be decreased after SG (− 49%). Sixty-five percent of patients still had vitamin D deficiency 1 year after surgery. Whatever the type of surgery, more than 20% had some vitamin deficiency 1 month after surgery.

Conclusions

Calories intake decreases after bariatric surgery, whatever the type of procedure. In addition, the prevalence of vitamin deficiency is high after bariatric surgery. Lastly, oral hydration is importantly decreased after bariatric surgery, especially after RYGBP.
