Long-term success of bariatric surgery begins with a comprehensive nutrition assessment designed to evaluate signs and symptoms related to the obesity problem unique to the individual. A food and nutrition history of eating habits, weight history, and family-related medical issues helps identify counseling needs for eating behavior changes and attitude about dietary supplement use.
Anthropometric measurements are needed to assess the diagnosis and treatment options. A presurgery diet for modifying portions and food choices—ketogenic low-carbohydrate diet, Mediterranean or dietary approaches to stop hypertension (DASH) diet, or low-glycemic diet— assists the candidate in preparing for surgery. A dietary supplementation regime helps bariatric surgery patients replete themselves with nutrients prior to surgery and develops a regular habit of supplementation intake postsurgery.
Objective measures of nutrition health are critical to determine a candidate’s understanding of nutrition requirements pre- and postsurgery. These include the following:
- • Anthropometric measurements
- • Daily food habits or diet history
- • Medication and dietary supplement intake
- • Medical history
- • Weight history
- • Clinical nutrition examination
- • Psychological support
- • Physical activity
Since biochemical assessments are usually not available, past medical history information regarding anemia, dyslipidemia, and blood glucose management needs to be obtained during the assessment.
