Newbie question for the guys: RYN vs. DS..What's the difference?
Since you didn't mention a laundry list of medical complications I assume you can take your time in making a decision. It really doesn't matter what other people think about one surgery or the other. I tried to listen to how happy people were with what they had, and I spent all the time I could researching medical literature, asking every doctor I could and scanning the net and reading about failed procedures and failed weightloss. I chose an open RNY after all that, consults with two different surgeons, and several months attendance at WLS support group meetings. Several websites (I think Mayo Clinic is one of them) allows you to watch the surgery performed.
In the end, there isn't any rivalry that matters. There's only living with your decision and your new lifestyle. My surgery is a week from today (God and the Insurance Company permitting). I'm ready!
Good luck to you,

I cut and pasted this from the same discussion the DS forum. I thought it would be helpful for people still in the research phase. I should note that I could care less which surgery someone has as long as they have all the information in front of them to make an accurate decision. There are reasons to have the DS, and there are some reasons to have the RNY (yes there are certain precancerious conditions..i.e. bartletes syndrom that require the RNY over the DS...at least in some doctor's medical opinion) Scott
RNY compared to DS
RNY - expected weight loss
- 50-65% expected excess weight loss (percentage varies in opinion – on average estimate)
- Results may vary
- Regain
- Can regain 50% of weight after 5 years
- 100% regain of weight has been recorded
- RNY must exercise and diet to maintain weight loss after 5 years
DS – expected weight loss
- 85% expected excess weight loss
- Results may vary
- Studies show little to no regain
- 20 lb gain from lowest weight has been recorded
RNY – have a stoma (stomach made into a pouch – size of an egg)
- Size: 2 oz
- Stretch to average size of 6 oz in 2 years (can stretch up to 9-10 oz)
- You can eat more as time goes by.
- Average after 1 year is 1-1.5 cups of food
- Stoma: blind pouch
- doctor evaluation cannot use an endoscope (to find ulcers and tumors)
- cannot take Nonsteroidal Anti-Inflammatory drugs (NSAID).
- NSAIDs are: Advil, Alka Seltzer, Aleve, Anacin, Ascriptin, Aspirin, Bufferin, Coricidin, Cortisone, Dolobid, Empirin, Excedrin, Feldene, Fiorinol, Ibuprofen, Meclomen, Motrin, Nalfon, Naprosyn, Norgesic, Tolectin, Vanquish
- NSAIDs are used for arthritis, bursitis, tendonitis, back pain, headaches, and general aches and pains. This could develop into a bleeding ulcer and interfere with kidney function.
- Possible Problems
- Ulcers (Doctor’s recommend taking Prilosec to try and prevent the ulcers)
- Possibility of a staple line failure
- Narrowing/blockage of the stoma
- Vomiting if food is not properly chewed or if food is eaten too quickly
- No Valves (pyloric valve that opens and closes to let food enter intestines is bypassed)
- This means food empties directly into the small intestines and causes dumping and NIPHS.
- Dumping: food (most commonly sugar but not necessarily just sugar) enters small intestines and causes physical pain (some people believe this pain enforces good eating habits)
- Dumping varies in degree of occurrence and discomfort
- Dumping symptoms:
- Nausea
- Vomiting
- Bloated stomach
- Diarrhea
- Excessive sweating
- Increased bowel sounds
- Dizziness
- Emotional reactions
- NIPHS (insulin over production): “the body overproduces insulin in response to food entering the intestines at a point where food would normally be more digested already - this part of the intestine is not used to coping with metabolizing glucose in the condition it arrives after RNY, and it is suspected that the intestine signals the pancreas for more insulin to aid digestion, causing a MASSIVE overproduction. The change occurs on a cellular level, hard to diagnose. Treatment: Removal of half the pancreas. A couple of folks who've had this done have posted on the message boards in the last 6 months.”
- RNY stoma that is created allows food to go straight through the stomach into the small intestine unrestricted so it does not control the flow. Because of that the body reads that it needs more insulin because the food is moving through so quickly and it thinks there's going to be a lot more food. With the DS, the normal peristalsis works because the pyloric valve is in place and can control the movement of food into the small intestines.
DS – whole stomach (size of banana)
- Whole stomach means 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; 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 NIPHS
RNY – Eating
- Recommended to chew food to liquid (most important early out)
- Foods need to be thoroughly chewed to prevent blockage (hole leaving stomach and into intestine is the size of an eraser).
- To get food unstuck, patients drink meat tenderizer mixed with water.
- 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
- Not encouraged to use a straw
- Low carbohydrates (carbohydrates can slow weight loss)
- Avoid sugars (in fear of dumping and slowed weight loss and/or weight gain)
- Eat protein first
- 60g of protein a day
- 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.
DS – Eating
- Daily intake of 80-100g of protein
- 64 oz of water
- Can drink with meals
- Can use a straw
- Low carbohydrates (carbohydrates can slow the weight loss)
- No dumping syndrome from eating sugar
- Only absorb 20% of fat (do not need to eat low fat)
- DS patients can eat more food than any other type of weigh loss surgery.
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
- Reversible procedure but complicated
- Revision often performed instead of revision
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
- Stinky gas
- Loose stool
- The intestinal bypass is reversible for those having malabsorptive complications
- Stomach portion removed is obviously not reversible
RNY - Diabetes
- RNY does not cure diabetes but puts it in remission.
- Can come back in two or three years--even if the
patient maintains most of their weight loss.
- Even a small weight gain long-term can cause a diabetes
relapse.
- 85% cure
DS – Diabetes
- A 98 percent cure rate for type II diabetes.
DS – Myth or Fact
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
- Vitamins and blood work must be monitored for life.
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
The DS is only recommended for the super morbid obese (bmi over 60) = Myth / Not True
- To be eligible for ANY type of weight loss surgery, a person has to be 100 lbs. over weight or have a bmi of 40 or more.
- BMI’s under 40 have also been approved (usually require a comorbidy/health problem - an example is sleep apnea).
DSers may need to wear a diaper = Myth / Not True
- That is silly
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 grows to adjust to the new digestive system.
Dser’s gas stink = true
- The gas does smell.
- There are products called air fresheners that a person can buy.
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 – so it the fatty food is healthier to eat as a post op than a person without surgery.
- Normal person eats a fatty meat that has 20g of fat, they absorb 20g of fat. A DSer absorbs 4g of fat from the same fatty meat.
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

OK, let's clarify. Neither DS or RNY "cures" diabetes T2. OTOH, both can quickly eliminate or greatly reduce one's need for medicines to keep one's blood sugar in line. Staple line ruptures: A risk in both surgeries. NSAIDs: If they bothered you before surgery, they'll probably bother you after surgery. Wouldn't recommend taking them in the first few months following either surgery.
Nutritional deficiencies: Risk for both surgeries. DS bypasses more intestine than RNY, so more risk, but still controllable. Both surgeries require lifelong supplementation.
Weight Regain: Possible with both. That is to say, once you learn what your new plumbing will tolerate, you can 'eat around' either surgery, and consume a LOT of calories.
In the US, RNY is generally considered the "gold standard" weight loss surgery, but I believe that is mostly the result of having good and consistent long-term results, as supported by a large statistical population of RNY patients. Since RNY is the most-frequently-performed weight loss surgery in the US, the track record is strong.
However, that does NOT mean that RNY is the "BEST" surgery - only the most documented. The "best" surgery for anyone is highly subjective, and highly personal.
We're all heading for the same destination. We needn't all take the same road.
