ObjectivesTo gain understanding of the nutrition care process for bariatric surgeryTo understand the different types of weight loss surgery procedures. To become informed about different complications and nutrient deficiencies that are commonly associated with bariatric surgeries.

DefinitionBariatric surgery is a surgical procedure designated for weight-loss in severely overweight people. It reduces and bypasses the stomach or small intestine in order to achieve significant and permanent weight loss.

DefinitionOverweight - A body mass index (BMI) 25-29.9Obesity - A BMI ≥ 30A waist circumference of ≥ 40 in. in men, and ≥35 in. in women carries increased risk.Morbid Obesity - BMI ≥ 40

Obesity and the U.S.Between 2005-2006, more than one third of U.S., or over 72 million adults were obese (33.3% for men, 35.3% for women) according to the most recent NHANES study“Recent data show racial and ethnic obesity disparities for women but not for men. Non-Hispanic black and Mexican- American women were more likely to be obese than non-Hispanic white women.”1Ogden CL, Carroll MD, McDowell MA, Flegal KM.

PurposeBariatric surgery performed only on people with morbid obesity or have obesity connected with chronic health disorders that are commonly linked with obesity.Overweight and obesity are significantly correlated with diabetes, high blood pressure, high cholesterol, asthma, arthritis, and poor health status.Researcher’s concluded bariatric surgery could help cure T2DM (Longe J. 2006)http://jama.ama-assn.org/cgi/content/abstract/289/1/76; Longe, J. (2006). The Gale Encyclopedia of Medicine. New York: Gale Cengage.

Who is a Candidate?Obese individuals who do not have any psychological, emotional, or medical problems.Must be between the of 18-60 years of age.Individuals over 100 lbs. of their ideal body weight.BMI ≥ 40BMI ≥ 35 with associated serious health problems such as diabetes and heart disease - due to their excess weight.

Current Bariatric Surgical Procedures

Procedure Classification

Roux-en-Y Primarily Restrictive/ Partially Malabsorptive

,

LaparoscopicGastric Banding Restrictive (Lap-band) Biliopancreatic Diversion Malabsorptive (BPD)

Roux-en-Y Gastric BypassA small (10-

30mL) pouch is anastomosed to a Roux limb of the jejunum. The length of the Roux limb determines the level of malabsorption and weight loss.

Laparoscopic Surgery

Laparoscopic surgery is a minimally invasive surgery.

The pouch created starts off at having the ability to hold 1 oz. of material.

Biliopancreatic Diversion

http://www.obesitysurgeryinfo.co.uk/exports/gb1.jpg

Removal of 70% of the stomach

In comparison to the RYGB, the length from the stomach to the intestine to the colon is much short-promoting malabsorption.

Due to its malabsorptive nature, the BPD requires lifelong follow-up

Optimal Weight Loss ProcedureAccording to clinical research study by the American Journal of Medicine, Roux-en-Y was favorable in comparison to laparoscopic adjustable gastric banding.After 1 year, excess weight loss was considerably greater for those with Roux-en-Y. Excess weight loss at 76% for Roux-en-Y, and 48% laparoscopic banding. Patient satisfaction favored Roux-en-YConcluded, surgery is a cost-effective intervention (Avenell et al. 2004)

General ComplicationsThe obesity epidemic within the U.S. has exponentially increased bariatric procedures performed which as therefore led to an increased awareness of the complications

Anastomatic leakThromboembolismInternal herniaUlcer formationCholelithiasisHemorrhageNutritional complications

Journal of the American Dietetic Association 2006

Surgery OutcomesOn average, morbidly obese patients will lose 60% more of their excess body weight than individuals using conventional weight loss methods (Buchwald et al. 2004)Success of the surgery is measured at losing 50% more of the excess body weight.

Pre-Operative Guidelines

Exercise: Mild exercise (20 min./day 3-4 times/week) Psychological EvaluationBegin healthful diet in order to assist weight loss

Post-Operative GuidelinesFor the first few days, small, frequent servings of water and ice chips (1oz.)

Progress diet as tolerated

LiquidsPureed FoodsSolid Foods

Initial gastric capacity is 30 to 60 mL, with a progression to 120 to 150 mL.

Patients need to eat for 20 minutes or more in order to induce the feeling of satiety and avoid bolus eating.

Food should be well chewed and eaten in small volumes

Post-Operative ContinuedLiquids

Not ingested during mealtimeConsume well before mealtime or 30 minutes prior 48 to 64 oz. (6 to 8 cups) daily of non-caloric liquids between meals

Preferably, proteins should be consumed before fats and carbohydrates.Post-operative dietary counseling plays an imperative role in the success of long-term weight loss.

Foods To AvoidCarbonated or Caffeinated BeveragesFried Foods Peanut ButterRaw Vegetables and Fruit Skins (for 3 months)Red Meat (for 3 months)High Sugar Containing Foods

Dumping SyndromeDumping syndrome may occur when concentrated sweets & high fats foods enter your intestine from your pouchOften occurs after individuals ingest high sugar foods such as deserts, sodas, and candy. It can also occur when spicy, fried, or greasy foods are eaten.Two types of dumping:

Early: 30-60 minutes after eatingLate: 1-3 hours after eating

Lifestyle Changes: New Habits

Eat small amountsEat and drink slowlyChew food thoroughlyDrink liquids between mealsTry new foods one at a timeTake your recommended vitamin/mineral supplements

Nutritional Considerations

Gastric Banding surgical patients may develop deficiencies in Iron and vitamin B-12Roux-en-Y procedures may induce nutrient deficiencies in calcium, iron, folic acid. In addition, dumping syndrome can be common in this procedure.Dehydration is a common concern for all of the procedures, along with an increase for gallstones.A vitamin/mineral supplement is generally recommended.

Bariatric Surgery: Nutrient Considerations

Nutrient deficiencies have been observed post bariatric surgery, particularly pertaining to Roux-en-Y surgery.*Iron*Vitamin B12*Folate*Calcium*Vitamin D*Protein

FolateIt is recommended that those with folate deficiencies should take 400 µg of folate consistently on a daily basis.Primary reason for deficiency is decreased folate intake

Malabsorption not at issueFolate can be absorbed over the entire length of the small intestine.

Also common in RYGB patientsAs high as 38% after surgery

CalciumCalcium deficiencies possibly due to:

malabsorption because of bypassing the duodenum and proximal jejunum. intolerance to rich sources of calcium such as milkdefective absorption of vitamin D due to fat malabsorption

Nutrition Care Process (NCP)

ADA considers quality nutrition care to follow these steps:1. Nutrition Assessment

BMI (overweight? obese?) Health historyInterpret data

2. Nutrition DiagnosisOverweight, Obese, Morbid ObesityDetermine contributing factors to patients health/ obesity

3. Nutrition InterventionFormulate plan/goals for the bariatric patient

4. Nutrition Monitoring and EvaluationMonitor success of NCP

Goals for the RDObtain current lab values for the patientSet short and long term goals for the patientDiscuss the pre- and post-operative dietary guidelinesSet-up support groups for the patient to stay actively involved in during their weight loss journey

Weighty Ethical Issues1. Should overweight or very obese individuals be encouraged or forced to gain more weight in order to be an acceptable candidate for weight loss surgery under governing medical and surgical guidelines?2. Should morbidly obese children and adolescents be able to be candidate’s for weight loss surgery?

SummaryThe U.S. population has overweight and obese percentages at epidemic proportions.When diet and exercise have proven to be a failure, obese individual’s can undergo bariatric surgery

Partially Malabsorptive/Primarily Restrictive: Roux-en-Y Gastric BypassRestrictive: Laparoscopic BandingMalabsorptive: Biliopancreatic Bypass

Summary Continued...Vitamin and Mineral, and Macronutrient deficiencies can occur after bariatric surgeryClosely monitoring fluid and food intake, and being careful to not ingest too much in a sitting is imperative in the success of the surgery and to prevent dumping syndromeThe NCP is a vital tool for the R.D. to comprehensively and accurately develop plans and goals for the bariatric patient

In Review...TRUE or FALSE: Biliopancreatic Diversion surgery is the most commonly used bariatric surgery used in the U.S.TRUE or FALSE: Gastric Bypass (Roux-en-Y) has been shown to be the most effective procedure in weight reductionTRUE or FALSE: Surgical patients are able to eat anything they would like once their surgery is complete.

Review...

What syndrome can occur if an individual eats too much sugar too quickly after surgery?When should liquids be consumed?
