Hello. I am new here. 17 years post-op RNY.
I dump. There are two types of dumping, 'early stage' and 'late stage':
Early Stage I don't remember the effects because I don't do this much. For me, it only involves brow sweating, usually soon enough to cue me to stop eating. For me, not a big deal. Sorry, my memory isn't what it used to be.
Late Stage (for me) takes about an hour to start. I get lethargic, light headed, sleepy, and whole body flop sweaty. Then intestinal distress, then diarrhea. Recently, one of my meds also caused me to pass out and made every effect worse. All in all an exciting time I could and strive to live without.
After all this time I generally know my body's limits and go months and years between episodes. When it get's me is when I feel under the weather or haven't eaten well for days and I don't notice and adjust.
Hope this helps,
Tek
