Dietary intake and food preferences change after bariatric surgery, secondary to gastrointestinal symptoms and dietitian counseling. The aim of this study was to evaluate the changes in the frequency intake of different foods in patients undergoing sleeve gastrectomy and following a strict dietary control.
Patients and Methods
A prospective observational study of all the morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between 2007 and 2012 was performed. Dietary assessment was performed using the Alimentary Frequency Questionnaire 1991–2002, developed and validated by the Department of Epidemiology of Miguel Hernandez University (Elche, Alicante Spain).
Ninety-three patients were included for analysis, 73 females and 20 males, with a mean preoperative BMI of 46.4 ± 7.9 kg/m2. One year after surgery, excess weight loss was 81.1 ± 8.3% and 5 years after surgery, 79.9 ± 6.4%. Total weight loss at 1 year was 38.8 ± 5.3% and at 5 years, 35.4 ± 4.9%. Postoperatively, a reduction in the intake of dairy products, red meat, deli meat products, shellfish, fried potatoes, sweets, rice, pasta, beer, and processed foods was observed. Vegetables, fruits, and legumes intake increased after surgery. In the first postoperative year, there was a slight intolerance to red meat, fruits, vegetables and legumes, dairy products, pasta, and rice that mostly disappeared 5 years after surgery.
One year after sleeve gastrectomy, calibrated with a 50-French bougie, there are not important problems in the intake of foods a priori difficult to digest. These problems mostly disappeared 5 years after surgery. The decrease intake of other unhealthy foods is mostly based on the dietary counseling.
