Nana,

While dumping syndrome may occur with the sleeve, it is generally avoided or minimized because the pylorus is present.  Dumping occurs more commonly with RnY and other gastric bypasses which remove the pylorus.

No matter what surgery we elect, limiting ingestion of simple carbs is a good idea; they can cause those inclined to do so to dump and they can also stall or otherwise inhibit weight loss.  Complex carbs, however, can be nutritious and, for vegetarians and vegans, are often the primary source of protein.

Advantages and Disadvantages of Vertical Sleeve Gastrectomy

Vertical Sleeve Gastrectomy Advantages

• Reduces stomach capacity but tends to allow the stomach to function normally so most food items can be consumed, albeit in small amounts.
• Eliminates the portion of the stomach that produces the hormones that stimulates hunger (Ghrelin).
• Dumping syndrome is avoided or minimized because the pylorus is preserved.
• Minimizes the chance of an ulcer occurring.
• By avoiding the intestinal bypass, almost eliminates the chance of intestinal obstruction (blockage), marginal ulcers, anemia, osteoporosis, protein deficiency and vitamin deficiency.
• Very effective as a first stage procedure for high BMI patients (BMI > 55 kg/m²).
• Limited results appear promising as a single stage procedure for low BMI patients (BMI 30-50 kg/m²).
• Appealing option for people who are concerned about the complications of intestinal bypass procedures or who have existing anemia, Crohn’s disease and numerous other conditions that make them too high risk for intestinal bypass procedures.
• Appealing option for people who are concerned about the foreign body aspect of Banding procedures.
• Can be done laparoscopically in patients weighing over 500 pounds, thereby providing all the advantages of minimally invasive surgery: fewer wound and lung problems, less pain, and faster recovery.

Vertical Sleeve Gastrectomy Disadvantages

• Potential for inadequate weight loss or weight regain. While this is true for all procedures, it is theoretically more possible with procedures that do not have an intestinal bypass. 
• Higher BMI patients will most likely need to have a second stage procedure later to help lose the rest of the weight. Remember, two stages may ultimately be safer and more effective than one operation for high BMI patients. This is an active point of discussion for bariatric surgeons.
• Soft calories such as ice cream, milk shakes, etc can be absorbed and may slow weight loss.
• This procedure does involve stomach stapling and therefore leaks and other complications related to stapling may occur.
• Because the stomach is removed, it is not reversible. It can be converted to almost any other weight loss procedure.
• Considered investigational by some surgeons and insurance companies.

Hey...Carmel...don't want this to get into something that it shouldn't...but remember the Sleeve is fairly NEW and many people did not KNOW that Dumping syndrome occurs...and this side effect is forever.

Remember I am almost 7 years post op and I have MANY FRIENDS that revised over to the Sleeve over the years starting as early as 2008 and ALL REPORT DUMPING SYNDROME...this is not bashing the Sleeve.. ONLY STATING FACTS of side effects of eating certain carb NOT ONLY SWEETS. And it is very  important information for those who may be looking to avoid RNY because it is well documented that RNY's dump and SO DOES SLEEVERS....and many did not know this until they had removed their stomach...some people are ok with this..and MANY are not.

Abstract

BACKGROUND:

Dumping syndrome is a well-known complication after upper gastrointestinal (GI) surgery. There are scarce data in the literature about the incidence of dumping after bariatric operations but, certainly no relation between this syndrome and laparoscopic sleeve gastrectomy (LSG) has been attempted.

METHODS:

We conducted a prospective clinical study in order to evaluate the potential presence, incidence and severity of Dumping syndrome after LSG. Thirty one non-diabetic morbidly obese patients (eight male, 23 female) eligible for LSG were evaluated. Median age was 38 (22-58 years) and mean body mass index (BMI) was 45.55 (± 5.37). The diagnosis of dumping syndrome was based on clinical provocation of signs and symptoms using an oral glucose challenge before and 6 weeks after the operation. The Sigstad's dumping score was estimated in order to separate dumpers from non-dumpers, and the Arts questionnaire was completed to distinguish between early and late dumping. Moreover, blood glucose levels during the oral glucose challenge were measured.

RESULTS:

No patient had symptoms of dumping after provocation preoperatively, whereas after LSG 9 patients (29%) experienced definite dumping and other 5 patients (16%) symptoms suggestive of dumping syndrome. Arts' questionnaire demonstrated that dumping occurrence after LSG was associated with early symptoms. Late hypoglycaemia occurred in one patient.

CONCLUSION:

A significant proportion of patients after LSG experienced dumping syndrome upon provocation. It seems that LSG should no longer be considered as a pure restrictive procedure, and it might be an option for heavy sweeters by changing their food tolerance patterns.

Also if anyone is interested they can just go to the top search bar and type in 'VSG dumping" they will get many post of dumping..its NOT an isolated issue...it is common..along with many other issues I would rather not say.

Many people reporting their dumping experiences

 I dump...but my Gastroenterologist calls it IBS.  Too many carbs will cause rapid heart rate, nausea, shakes, lightheadedness, cramping, diarrhea....this has been happening for a good 20 yrs.  sometimes it's not the surgery, but the individual.

I"m aware of the dumping, I'm not a big carb person and I'm not fond of sweets other than soda. I've already know I need to give that up for other reasons related to bone & vitamin issues I'm having.. But, I've done the research and independenty interviewed over 150 random VSG'ers over the past year. All have given me considerable belief that I'll be able to handle proteins better than with the band, barring any unforseen complicatons or other medical issues.

Thanks for taking the time share and your well wishes.

I'm glad to hear you have a plan. You'll feel so much better once you get the band removed. When it gets to the point where you have chest pain every time you try to eat healthful foods, you know it's got to go.

Wishing the best for you in your removal and/or revision.

Don't listen to the people who try to place blame upon you. That's rude and foolish of them. They're apparently "barriers" (sic) of bad news. Well, I'm the bearer of good news... you WILL feel better without the band. Most of us do.

GOOD LUCK TO YOU! 

Thank you I ignore the nasty people who blame me. I blamed myself for a long time too. Their opinion doesn't' have an affect on me because they don't matter as people to me. As for others that give their opinion and advise in a respectful format, I embrace it and discuss it. It's how I've learned and researched all of this to come to this decision. I'll keep everyone posted.

I'm so sorry to hear of your struggles with the band.

DO NOT allow Naomi to scare you with her little tidbits on dumping. A mere 16% of VSG patients dump, and even then it's not the same effects that are found with RNY dumping. Transit time has more to do with "dumping" symptoms than anything and that is a well-studied, well-documented findings since gastrectomies have been performed for decades upon decades for cancer and ulcer patients.

The sleeve is the best decision I ever made for myself and believe me, every food that got stuck with the band (might I add a barely filled band so that isn't brought up and thrown in my face), has never given me a single issue. It's nice to not puke, slime, productive burp, okay so it's better than nice, It's FLIPPIN' AMAZING ! ! ! 

I work 911 EMS  in a very large urban gang/drug infested city. I worry about being car jacked & shot every work day. I don't scare easily ;). I've done the research, I know the risks. I went in for a filing change once just for cosmetic changes and wound up with the worst root canal of my life. Anything bad can happen at anytime in any procedure. I'm feeling confident. I take the good & bad comments as learning tools, just as long as everyone is polite (and thus far they have been). Thanks so much for your info as well and congrats on that  Nugget!!!

Thanks to everyone and their kind regards, well wishes and information. If I missed replying to anyone I apologize. For some reason I'm not being notified of any replies even though I have that box checked. Thanks again.
