Hi all! I have noticed that many folks here on TT are not quite clear on what exactly "dumping syndrome" is. So I thought I'd provide a little info on the topic.

"Dumping" is a medical term describing a condition/complication that can occur in someone who has had gastric surgery (usually associated with the removal of the pyloric valve). Some may confuse lactose intolerance, an irritated pouch, inability to tolerate certain foods, and simply diarrhea or vomiting with "dumping". However, true "dumping" involves a specific suite of symptoms that may or may not include vomiting and/or diarrhea and is usually caused by eating sugar, carbs, and to a lesser extent, fats. Dumping does not occur in pre-gastric bypass folks and only occurs in approximately 30% of post-bypass patients. The condition can usually be controlled by avoiding foods high in sugar, carbs and fats, eating slowly, and not drinking with meals. In other words, following our surgeon's recommended plan:)

I have included info on dumping syndrome from the Mayo Clinic website and a bit from Wikipedia.

"Dumping syndrome is a group of symptoms most likely to develop if you've had surgery to remove all or part of your stomach, or if your stomach has been surgically bypassed to help lose weight. Also called rapid gastric emptying, dumping syndrome occurs when the undigested contents of your stomach are transported or "dumped" into your small intestine too rapidly.

Most people with dumping syndrome experience symptoms soon after eating. In others, symptoms may occur one to three hours after eating. In either case, symptoms can range from mild to severe and may include:
  • Nausea
  • Vomiting
  • Abdominal pain, cramps
  • Diarrhea
  • Dizziness, lightheadedness
  • Bloating, belching
  • Heart palpitations, rapid heart rate
  • Sweating
  • Weakness, fatigue
  • Shakiness
  • Feelings of anxiety, nervousness
  • Heart palpitations, rapid heart rate
  • Fainting
  • Mental confusion
  • Low blood sugar (hypoglycemia)
In dumping syndrome, food and gastric juices from your stomach move to your small intestine in an unregulated, abnormally fast manner. This accelerated process is most often related to changes in your stomach associated with surgery. For example, when the opening (pylorus) between your stomach and the first portion of the small intestine (duodenum) has been damaged or removed during an operation, dumping syndrome may develop.
Dumping syndrome may occur at least mildly in one-quarter to one-half of people who have had gastric bypass surgery."

"Rapid loading of the small intestine with stomach contents can lead to rapid entry of water into the intestines.
In addition, people with this syndrome often suffer from low blood sugar, or hypoglycemia, because the rapid "dumping" of food triggers the pancreas to release excessive amounts of insulin into the bloodstream. This type of hypoglycemia is referred to as "alimentary hypoglycemia". (Wikipedia)

I hope this helps clear up some of the confusion over the topic and the use of the medical term, "dumping."

Thank you for this - I just had my 4 month visit with my surgeon. I get really bad shakes if I eat high fat foods and he says this can be dangerous. I have to monitor my sugar levels and eat something bland like fruit or bread to 'come down" as there is the danger of passing out. The best thing however is not to over eat fats!
Thank you again for the article.

Thank you so much. I'm 7+ mos post-op and wondered why I was getting the palpitations when I ate too much of something (ALWAYS with something I shouldn't have eaten).

It hasn't been long since your surgery. Don't worry, there's still hope! Have you tried cutting out dairy for a few days? You may be experiencing some temporary lactose intolerance. It's not uncommon in the first couple of months after surgery. And it often resolves itself so you don't have to avoid dairy forever.

I get a very rapid heart beat, palpitations and shaky. This is if I eat -anything- too quickly (like scarf it down) or if I eat something too high in sugar or even sugar alcohols. The heart racing can last quite a while and tires me out big time. It spikes up past 110 bpm and I have to sit down and rest while it's happening.

I didn't figure out that this was dumping until about 8 months post op. Bananas are the number one food to do it to me.

Like BDM said, it's not ALL the symptoms and it's not only vomiting / diarrhea. Mine is just the heart issues, but it is classic to dumping nonetheless. Watch your bodies, folks, it tells us a lot about what foods are and are not okay to eat anymore.

When I have sugar free stuff or too much sugar, I get so nauseous, my heart beats fast and hard, my head feels weird - a bit confused, I have to lay down and sleep.

I've had a few weird experiences but not vomited (except when I had stuck food once) and diarrhoea once when I over ate (2 egg omelette) and oh my, the stomach pains were horrific!

Is this dumping?

3 hrs after i ate today, I decide it was time to start drinking some water. No problems up to this point. I took a couple of drinks of water and now I am sick. I feel like I need to throw up but can't. I can't swallow my spit either and my nose runs like a fosset. I have to keep spitting the spit out - its almost involuntairy. This is about the 3rd time this has happened to me. It is always several hours after eatting. Only one of the three times did I eat any thing sweet before these episodes but all three times (now that I think about it) i did have small amounts of mashed potatos (approved on my diet right now). Does this mean I can't eat mashed potatos?

That's what happened to me when I had food stuck but I knew something was stuck by the pressure feeling (and it wasn't 3 hours later).

This doesn't sound like dumping. Dumping usually happens pretty quickly after eating. As Sarah mentioned, what you are describing sounds more like what happens when something gets "stuck". It sounds like you tried to drink and it would not go down because the food from earlier was blocking it. This is something you may want to describe to your surgeon. You are in the prime window for a stricture, which is a narrowing of the hole leading from your pouch to your intestines. If that is what is happening, your surgeon will be able to treat it fairly easily.

Thanks for posting this. I've been assuming that I don't dump, even though I get the rapid heartbeat and abdominal pain, and sometimes nausea/vomiting. I somehow thought you had to have the cramping and diarrhea- which I don't get. Still relatively mild, but I'm glad to know that the surgery's working.

I am only 3 weeks out so I am learning more daily.

Is there a difference between sugar dumping and fatty food type dumping?

While eating SF Popsicles , right after surgery, I got the sweats and flue like symptoms along with dizziness. Then straight to the bathroom with diarrhea. That happen twice but now I can eat SF Popsicles without problems. This new type of dumping I have had the pleasure of meeting up with is much more vicious! Three nights ago I ordered plain mashed potatoes at a lounge while listening to a friend perform. No sweats were involved but heavy cramping found its way into my bowels, OMG it hurt. Dizziness and flu like symptoms were there as well as diarrhea. It all lasted about an hour and afterwards I was dead to the world; I slept for about an hour as soon as we got into the car. Last night while watching the Superbowl I had a serving of split pea soup. I have had split pea soup in the past without issue; however, I had pureed the soup in the past. Pureed is the only difference, but I dumped bad last night! I didn't sleep but I was totally exhausted after wards for about an hour and then I started getting my strength back! This past weeks two dumping episodes had no sweating issues but a lot of cramping!

So I ask, is there two types of dumping, one for sugar and one for fats?
