To review the literature for nutritional, fluid, and exercise recommendations in patients who have undergone bariatric surgery.
Data sources: PubMed (1980 - October 2008). The bibliographies of selected literature were reviewed for additional sources. A systematic review of the literature is presented. There is little high-quality evidence to support any recommendations currently. Most recommendations are expert opinion. Nutritional deficiencies are common. Routine screening and nutrient replacement is adequate for most deficiencies. Increased physical activity before surgery is associated with improved quality of life. Walking is adequate as a primary activity after surgery. Pedometers may serve as a useful tool to help guide exercise recommendations. There is need for further research upon specific exercise recommendations.
