  1. Nutritional Considerations After Bariatric Surgery Michelle Lee, PhD, RD, LDN Assistant Professor-Nutrition Department of Allied Health College of Clinical and Rehabilitative Sciences ETSU

  2. Objectives: • What are the short-term nutritional implications for individuals receiving bariatric surgery? • What are the long-term nutritional implications for individuals receiving bariatric surgery?

  3. Bariatric Surgery Trends • Between 2003 and 2008, bariatric surgeries peaked in 2004 and has remained steady(1) • Number of weight loss surgeries increased from 103,000 in 2003 to ~220,000 in 2008(2) • Bariatric surgery in NOT a quick fix for morbid obesity • There are nutritional implications for any bariatric surgery

  4. Types of Bariatric Surgery • Restrictive • Laparoscopic adjustable gastric band (LAGB) • Vertical banded gastroplasty (VBG) • Intragastric balloon • Malabsorptive • Bilopancreatic diversion with duodenal switch (BPD/DS) • Jejunoileal bypass • Bilopancreatic diversion (BPD) • Primary Restrictive with a Malabsorptive Component • Roux-en-Y gastric bypass (RYGB)

  5. Laparoscopic Adjustable Gastric Band

  6. Roux-en-Y Gastric Bypass

  7. Nutritional Implications of Various Bariatric Surgeries(3,4) • RYGB • Malabsorption of Vit B12, Vit B1 (thiamin), Vit D, Vit K, Folate, Iron, Calcium • LAGB • Folic Acid deficiency • BPD and BPD/DS • Vit A, D, E, and K deficiency, Protein-Calorie Malnutrition, Malabsorption of Calcium, Zinc, Selenium, Sodium, Potassium, Chloride, Phosphorus, Magnesium

  8. Sites of Nutrient Absorption(4) • Stomach • Water, ethyl alcohol, copper, iodide, fluoride, molybdemum, intrinsic factor • Duodenum • Calcium, iron, phosphorus, magnesium, copper, selenium, thiamin, riboflavin, niacin, biotin, folate, vitamins A, D, E, K

  9. Sites of Nutrient Absorption(4) • Jejunum • Thiamin, riboflavin, niacin, pantothenate, biotin, folate, vit B6, vit C, vit A, D, E, K, dipeptides, tripeptides, calcium, phosphorus, magnesium, iron, zinc, chromium, manganese, molybdenum, amino acids • Ileum • Vit C, folate, vit B12, vit D, vit K, magnesium, bile salts/acids

  10. Macronutrient Concerns • Protein • Carbohydrates • Fat

  11. Micronutrient Concerns • Iron • Calcium and Vitamin D • Vitamin B12 • Folic acid • Thiamin • Zinc

  12. Recommended Daily Supplements(4) • Multivitamin with iron (prenatal vitamin will have adeq amount of folic acid) • Calcium (citrate) with vitamin D (1200-1500 mg calcium with 800-1000 IU vitamin D) • Oral vitamin B12 (500-1000 mcg) • Iron (65 mg/day in elemental form) • Vitamin C (to increase absorption of Iron) • Thiamin (10 mg/day)

  13. Diet Progression After Bariatric Surgery(5) • Clear Liquids • Full liquids • Pureed food • Mechanical soft food • Soft food • Regular diet

  14. Diet Recommendations(3) • Reduce food volume • Chew food very well • Slow pace of eating • No liquids with meals • Encourage fruits and vegetables as diet progresses • Include high protein foods (at least 60g/day); may need protein supplements
