7. BARIATRIC SURGERY
Bariatric surgery is more effective
than nonsurgical treatment for weight
loss and control of some comorbid
conditions in MORBID OBESE patients

8. PRE-SURGERICAL
EVALUATION.

9.  Prior to surgery candidates should be carefully
assessed by a specialized multidisciplinary team
including:
 Bariatrician (MD specializing in the care of the obese)
 Surgeon
 PCP
 Social Worker/ Psychologist
 Dietitian
 Nurse

10. • During active weight management,
multicomponent interventions that are
delivered through multidisciplinary care may
be more effective than interventions delivered
by individual health professionals (Flodgren et
al. 2010; Tsai & Wadden 2009).

IN
BARIATRIC SURGERY
IN
MORBID OBESE
TREATMENT

12. Pre-Surgical Goals
 Improvement of nutritional status
• Correct vitamin/nutrient deficiencies (most common include:
iron, vitamin B12 and vitamin D)
Achievement of better control of nutrition- related
comorbidities
Development of lifestyle and eating habits that will
promote positive post-weight loss surgery outcomes
and weight loss maintenance
Promote 5-10% weight loss to reduce surgical risks

13. Post-Surgery
Nutrition Guidelines
• Dietary consult ordered upon admit
– Complete nutrition assessment
– Review diet progression with patient
– Work with in-patient team to identify & minimize
complications post-op
• For all procedures patients will follow the
same diet

14. Post Surgical Diet
Progression

15. Diet advanced from NPO to Stage 1 Bariatric Diet on
Post op Day 1
• Stage 1 - Water
– Typically start day of surgery; Duration < 1 day
– Nursing staff to administer 1oz water per hour via
medicine cup
• Instruct patient to sip slowly & stop if feeling full or
nauseous
– All medications to be administered in liquid/chewable
form
– IV Fluid until tolerating liquids
– Patient to begin tracking fluid intake on Patient Intake
Diary (provided by healthcare team)

16. • Stage 2 - Bariatric Clear Liquids
– Starts Post op Day1; Duration 1-2 days
– Non-carbonated liquids without calories, sugar, or
caffeine; includes broth, sugar-free (SF) ice pops, SF
gelatin, water, & ice chips
– Priority is hydration
– Instruct to sip slowly & stop if feeling full or nauseous
(avoid straws)
– Will receive 3oz Bariatric Clear Liquids 3 times a day on
meal trays
– Instruct to sip 2-4 oz Bariatric Clear Fluids per hour
between meals
– Will be expected to track intake on Patient Intake Diary

17. Stage 3 - Bariatric Full Liquids
• Starts Post op Day 1-2; duration 2-4 weeks
• Will receive 3oz Bariatric Full Liquids 3 times a day on meal trays
• Low-fat protein-rich liquids with (exp. Low-fat (LF) broth, LF milk,
protein shakes; light/LF yogurt, LF cottage cheese; LF/SF
pudding) juven/beneprotein
• Priority on hydration and protein intake (minimize loss of lean
body mass)
• Instruct to sip slowly & stop if feeling full or nauseous
• Instruct to sip 2-4 oz fluids per hour between meals
• Note: Patients will go home on this stage. You may not see
other stages unless patients are re-admitted

18. Stage 4 - Soft and Moist Protein
• Start 2 weeks post-op; Duration 4-6 weeks
As tolerated replace full liquids with soft & moist protein
foods (avoid dry or tough meats); ~2-4oz per meal
• May need to continue with protein shakes to meet protein
needs
• Instruct not to drink fluids with meals; wait 30 min before &
after each meal to have beverages
• If meeting protein goals may add well-cooked soft fruits &
vegetables
• Will begin taking chewable vitamin & mineral supplements

19. Stage 5
• Low Fat, Low Sugar, High Protein
• Start 6-8 weeks post-op; Duration lifelong
• Balanced solid food diet with protein, fruits, vegetables, and
whole grains. Can add raw foods as tolerated.
• Goals:
– 60-80 grams protein /day
– 64+ ounces fluid/ day (including protein drinks) sipped
between meals.
• Continue to separate fluids from your meals
• Can advance to supplements in tablet form if tolerated

20. Common Problems
After All Weight Loss
Surgeries

21. • Dehydration
– Monitor for signs and symptoms of dehydration as
patients are at greater risk given their dietary restrictions.
Patients should strive for 64 ounces of liquids per day.
• Nausea and Vomiting
– Eating too quickly or too much, drinking with meals or
drinking too close to meals, not chewing thoroughly, or
advancing the diet too quickly can all lead to nausea
and/or vomiting. Persistent vomiting can lead to thiamin
deficiency.
– Encourage patients to drink and eat slowly, stop if feeling
full or nauseous, and take small bites and chew their foods
thoroughly.

22. • Dumping Syndrome
– Usually occurs ~30 minutes following a meal.
– Symptoms may be similar to the flu and include nausea,
sweating, bloating, abdominal cramps, and diarrhea.
– To avoid these symptoms patients should avoid high fat and
high sugar foods. or example instead of 100% fruit juice; dilute
1:1 with water.
• Diarrhea
– Some patients can develop post-operative lactose intolerance.
Symptoms could include bloating, abdominal cramps, excessive
gas, and diarrhea.
– Treatment includes following a lactose-free diet.

23. Sites of Nutrient
Absorption

24. • 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
Shikora SA, Kim JJ, Tarnoff ME. Nutrition and gastrointestinal complications of bariatric
surgery. Nutr Clin Pract. 2007;22(1):29-40.

25. • 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

27. Common Nutrient
Deficiencies

28. • Gastric Bypass:
– Most common: Iron, Vitamin B-12,
Folic acid, Fat soluble Vitamins A, D, & E
– Thiamin (seen in patients with frequent vomiting)
– Calcium
– Protein malnutrition
• Gastric Banding:
– Except for folate, nutrition deficiencies are less
commonly seen post gastric banding
• Sleeve Gastrectomy
– Possible B-12

29. Iron deficiency and anemia
• As high as 49% of patients
• Multifactorial cause
– Low gastric acid levels prohibit iron cleavage from food
– Absorption inhibited because no nutrient exposure to
duodenum or proximal jejunum
– Decrease in iron-rich food consumption due to
intolerance
• Treat with oral supplementation of ferrous sulfate
or ferrous gluconate

30. Vitamin B12 deficiency
• Up to 70% of patients
• Lack of hydrochloric acid and pepsin in stomach
– Prevents B12 cleavage from food
– Affects secretion of intrinsic factor, thus B12
absorption
• Intolerance to meat and milk
• Oral supplementation usually adequate,
otherwise, IM injections used

31. Folate Deficiency
• 40% of gastric bypass patients
• Complete absorption requires B12
• Absorption dependent on HCl and upper 1/3
stomach
• Deficiency generally caused by decreased
consumption
• Oral supplementation

32. Vitamin D and Calcium Deficiency
• Vitamin D deficiency is common among obese
people
• Calcium absorption decreased because duodenum is
bypassed
• Intolerance to dairy, foods high in calcium
• Vitamin D is required for Ca++ absorption
• Prolonged deficiencies lead to
– Bone resorption, osteomalacia, osteoporosis
• Treat with calcium citrate supplementation and 2
weekly doses of Vitamin D

35. LONG TERM
SOLUTION

36. • Lifelong compliance with vitamin/ mineral
supplementation is important to reduce the
risk of serious nutrient deficiencies
• Self-monitoring intake and avoiding high
calorie foods and beverages to prevent weight
re-gain
• Remaining connected with post bariatric
surgery support groups

37. • Prevention is likely to be the most efficient
and cost-effective approach for tackling
overweight and obesity.
• However, many people already require
treatment, may have comorbidities and are at
risk of further weight gain (NPHT 2009).
