DUMPING?

I dump

When I have foods with too much fat/sugar my heart accelerates, my hands shake, I get a general feeling of unwellness (hard to describe) and I HIGHLY regret eating whatever I ate.

1/2 a fiber one pop tart - AWFUL
8 oz of a campbells tomato "soup at hand" ..... DREADFUL
10 g of sugar if it is a high fructose corn syrup will do me in, but straight up table sugar doesn't affect me as much. Particularly if it has no fat as part of the combination.

If I consume high sugar content foods I also get "late dumping" which is reactive hypoglycemia and that is ten times worse....

My heart accelerates way more than regular dumping (once I recorded it at 240 bpm)
I become soaked in sweat
My hands become vvery shaky
My ability to think clearly goes right out the window
I get nauseous and have no desire to eat (and MUST eat if I do not want to pass out) 

Dumping and Reactive Hypoglycemia are ..... I CONSIDER.... BAD complications of RNY and when I'm having a bad bout with both (as they go together) I really regret this surgery.

I am pre-op and a "know nothing"  :)  so please don't take this as argumentative... but isn't dumping part of the reason RNY works?  My NUT said the malabsorption is just part of it, the lifestyle enforced by dumping is another.  So it wouldn't be a complication, right?

  I am scared to death of dumping. I can't even imagine the severity of the RH.... *shiver*

I don't think I've dumped but I'm only about 5 months out.

There are times after I've eaten that I've felt 'ick' or lethargic but haven't had any of the shakes/sweats...

I'm sure it will happen one day, it makes me a bit nervous tho.
