Dumping ?
Grim is correct. Fats may cause digestive upset (I am nearly 7 years out and am more sensitive to fat than to sugar), but they do not cause dumping. Dumping is a very specific physiologic reaction to to much unprocessed sugar/carbs in the lower intestine due to the bypassing of the upper intestine. You may eat something that causes you to develop digestive upset that includes some of the same symptoms that are found in dumping, but it is not technically dumping.
You cannot dump from water! That is possibly THE most ridiculous thing I have ever read here.

You don't drown by falling in the water. You drown by staying there.
I never set out to test the waters, but have had a few experiences where I mindlessly started eating candy and then had the pounding heart and dizziness. For me it has been eating sugar on an empty stomach and no****ching the amount I was eating.
I would not dump from one candy bar, or one cookie, or one piece of cake. It is from quickly eating a lot of sugar at one time.

Real life begins where your comfort zone ends
While on vacation 6 weeks after surgery, I grabbed the wrong yogurt from the fridge. As I finished my last spoonful, I noticed it had 26 grams of sugar. Within 15 minutes, I found out I DUMP! I will never eat anything without reading the label again. In a way, I'm glad. Just another tool to use to make good choices.
CEEMREE--26gm??? Bless your heart!! I bet some peeps would say "Didn't she notice it TASTED good"??...but not ME...some of those new low sugar/low fat yogurts are dang..esp some of the new greek ones (Dannon, I think were the last ones I had)..
I could TOTALLY make the same mistake...ONCE anyway!

At first, dumping was immediate. I could be at a restaurant, eat something then run for the bathroom. Dumping is not the same as gastric discomfort. Dumping is the sudden onset of profuse sweating, rapid heartbeat and rapid respiration. It makes me dizzy, and the really sick feeling that overcomes one is indescribably frightening. It lasts, usually, about 20 minutes for me but depending on what caused it I can usually minimize the distress. If something had too much fat, I can drink water and try to dilute. Same with sugar. Drink as much water as you need to try to dilute whatever it is you ingested that caused you to dump. Start with 4oz and go from there. You'll start to feel better as soon as you strike the right balance and your gut is able to move the bad stuff or dilute it down. Everything has the potential to cause dumping but early in you'll probably have more trouble from not chewing long enough or taking too big of a swallow and that feeling is pretty bad. You feel nauseous instantly and your body's attempt to clear the food causes mucous to form which creates a *foam* that you have to keep spitting out. It's pretty nasty. All you need is common sense and good resources. Mistakes happen, expect them to happen to you and know what to do if you make one :)
Foamies are NOT DUMPING! You've been around long enough, you should know this.
Foamies are from eating too much, or not chewing something well enough, and getting stuck.
Not dumping!
Dumping happens withing 30 minutes of eating, usually much quicker. Some refer to "late dumping," which is entirely different. The proper term for late dumping is reactive hypoglycemia. Not the same as early dumping, or rapid gastric emptying, at all.
Common sense and good resources to not reside in your response at all.
Every gastric distress is not dumping.

Don't forget about "delayed dumping". At 12 years out, I still get it..sometimes BIG time...rarely immediately, and never intentionally, of course. Curling up on the cold floor of restaurant stall floors is never a fun time (even though I guess it IS a NSV to be able to FIT in the stall)....
