Nutritional deficiencies after sleeve gastrectomy and Roux-en-Y gastric bypass at 10 years: secondary analysis of the SLEEVEPASS randomized clinical trial.

ABSTRACT:

Background

Long-term data on the prevalence of nutritional deficiencies after laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) in RCTs are lacking. The aim of this study was to compare nutritional deficiencies and adherence to vitamin supplements after LSG and LRYGB at 10 years.

Methods

This was a predefined secondary analysis of the Finnish SLEEVEPASS (LSG versus LRYGB for severe obesity) multicentre RCT, with 10-year nutritional laboratory measurements and completed questionnaires on micronutrient supplement use, to assess the prevalence of micronutritional and macronutritional deficiencies and adherence.

Results
