• “Whole working stomach” - meaning the stomach’s outer curvature is removed as opposed to making a pouch/stoma.
  • Part of the stomach removed is where most of the hormone called Grehlin is produced.
  • Grehlin gives the sensation of hunger so by removing most of that section of the stomach a DSer is not as hungry as before.
• Whole working stomach: no blind stomach.  Endoscope can be used.
• Can take NSAIDs
• Do not need to take Prilosec to prevent ulcers.
• Valves are in tack: no Dumping Syndrome or NIPHS

 RNY – Eating

• Eat protein first
  • 60g of protein a day
• Recommended to chew food to liquid consistency (pureed, soft, thoroughly chewed)
  • This is more important for people early out (new pouch stomach will stretch out with time).
  • Food is thoroughly chewed to prevent blockage (the hole/path leaving the stomach and into the intestine is roughly the size of a dime).
  • To get food unstuck, patients drink meat tenderizer mixed with water.
• Low carbohydrates
  • Carbohydrates can slow weight loss and lead to possible regain
  • Avoid sugars in particular (to prevent dumping syndrome)
• Low fat
  • Foods high in fat may cause Dumping Syndrome
  • Fatty foods can lead to slow weight loss or possible regain
• 64 oz of water
  • Stop drinking within 15-30 minutes of a meal
  • Do not begin drinking after a meal for 1-1.5 hours
  • Some doctors do not encourage the use of a straw (pushes food too quickly through the stomach and can cause gas/discomfort)
• Water Loading
  • 15 minutes before the next meal, drink as much as possible as fast as possible. 
  • Water loading will not work if you haven’t been drinking over the last few hours.
  • You can water load at any time 2-3 hours before your next meal if you get hungry, which will cause a strong feeling of fullness.
    • Disclaimer: this is a practice some people use to feel “full” and lose weight. Not a requirement.

DS – Eating

• Eat protein first
  • 80-100g of protein
  • DS patients can on average eat more food than any other type of weight loss surgery.
• Low carbohydrates
  • Carbohydrates can slow the weight loss and lead to possible regain
  • No dumping syndrome from eating sugar (or fat)
• Eat high in fat
  • DS only absorb 20% of fat (do not need to eat low fat)
    • If a taco has 20g of fat, a DSer only absorbs 4g while a person without surgery or RNY absorbs ALL 20g. (this is just an example, measuring absorption is not an exact science)
    • When experiencing a “stall” (slowed weight loss/plateau) a DS patient commonly increases fat consumption to resolve
• 64 oz of water
  • Can drink with meals
  • Can use a straw

RNY – Possible Issues

• Vitamin deficiencies: Must follow a vitamin regime for the rest of your life
  • Common vitamin deficiencies found in vitamins B12, iron, and zinc
  • Calcium must be supplemented for the rest of your life
• Bathroom issues
  • Gas
  • Constipation
  • Dumping in the form of loose stools
• Reversible procedure (Reversals of any surgery is very complicated)
  • Revision often performed instead of reversal
  • Revising to a different type of surgery is possible.

 DS – Possible Issues

• Vitamin deficiencies: Must follow a vitamin regime for the rest of your life
  • Common vitamin deficiencies found in vitamins A, D, and iron
  • “Water soluble”/ “water miscible” / “dry” vitamins absorb best (in other words get vitamins that are not fat/oil based)
  • Calcium must be supplemented for the rest of your life
• Bathroom issues
  • Gas
  • Loose stool (Most common in the first few weeks of surgery. Generally food related)
• Reversible procedure
  • The intestinal bypass is reversible for those having absorption complications
    • revision: lengthening common channel (to stop losing weight and/or to absorb vitamins)
  • Stomach is obviously not reversible (part of stomach was removed)

RNY - Diabetes

• 85% cure rate
  • RNY can put diabetes in remission.
  • Diabetes may come back in two or three years--even if the
    patient maintains most of their weight loss.
  • Even a small amount of weight gain, long-term, can cause a diabetes
    relapse.

 DS – Diabetes

• 98 % cure rate for type II diabetes.

DS – Myth or Fact

The DS is only recommended for the super morbid obese (BMI over 60) = Myth / Not True

• To be eligble for ANY type of weight loss surgery, a person has to be 100 lbs. over weight or have a body mass index (BMI) of 40 or more.
• BMI’s under 40 have also been approved (usually require a comorbidy/health problem - an example is sleep apnea).

The DS is “experimental and investigational” = Myth / Not True

• Medicare approves the DS
• Many insurance companies are starting to cover the DS.
• DS has been performed since the 1970s

DSer will have a problem when they become old = Not True

• We wont need to eat as much when we are older b/c our bodies will adapt
• The little hair-like villa located in the intestines grows longer to adjust to the new digestive system (grows longer to increase absorbtion).

DSer’s gas stink = true

• The gas does smell. (This is true for the DS and RNY)
• There are products called air fresheners that a person can use.
• May take Flagyl or fish zole

DSers may need to wear a diaper = Myth / Not True

• That is silly

Skin color turns yellow or pallor = Myth / Not True

• Patients who follow their regular vitamin regime (keep up with blood work) do not turn pallor
• If someone looks pallor, they could have a vitamin deficiency.  This applies to any type of weight loss surgery. For both RNY and the DS.
• Vitamins and blood work must be monitored for life. For both RNY and the DS.

DSers will have a heart attack from all the fatty food they eat = Myth / Not True

• Cholesterol levels lower after having the DS. 
• 80% of the fatty food is not absorbed – the fatty food is healthier to eat as a DSer than a person without surgery.
• If a taco has 20g of fat, a DSer only absorbs 4g while a person without surgery or a person with the RNY will absorb ALL 20g.  Good meal for the DSer. (this is just an example, measuring absorption is not an exact science)

Dsers don’t need to exercise = Myth / Not true

• DSer’s are aware of the benefits of exercise (body and soul).
• Exercise helps in losing weight and maintaining goal weight 

 *Some practices may not be used by all patients. Some recommendations will differ depending on a person’s surgeon.  Possible issues are just that, “possible; and may or may not occur.  

Not every surgery will be right for everyone. Not every surgery will be covered by insurance. Good luck to everyone and thank you for reading my comparison chart. Hayley F.
