I had RYN 11/12/07 and I have had many of the same complications as you have described.... I have had 3 small bowel obstructions, gall bladder removal, hernia removal and the last 2 surgeries I had perforated holes in my intestines and Ecoli leaked into my blood stream.  Since then I have been in and out of the hospital with vomiting, nausea, and this burning pain in my stomach.  All my test come back negative...... It makes you feel as if your making the whole thing up. 

My life is so stressful......I was a person that never called off sick and now I don't have anytime left on my job.  I cant make plans to do anything with my family because I stay sick more than I'm okay.   It seems that if I eat anything seasoned or with a little bit of grease it will trigger a bad attack that last for hours at a time.  Sorry for rambling on and on, but boy do I feel your pain....  I never knew things would be like this!

I had severe problems with nausea after my surgery that never went away.  I had several EGDs, Gallbladder removal, and was on SEVERAL medications for nausea all at once. (My surgeon actually told me that he thought it was all in my head at first, so you are doing good if your surgeon isn't saying this.)  I had two feeding tubes... let me give you some advice on that one..

I don't know what they are giving you through your tube, but there are several types of formula.  Some of them cause you to dump more than others.  I KNOW this doesn't make sense because it is going into your old stomach, but TRUST ME... You still dump.  I tried several different kinds of formulas with my tube, and I still dumped.  My doctor ordered a pump.  I pumped continuisly through the night.  The dumping went away.  I am sure that it was because i slept through it, but that is all that matters.

I am surprised that this is an option that they are giving you so fast.  They usually wait for at LEAST a year.  I had a reversal done 10/23/09.  Even after the reversal.... I thought I was going to live with the nausea forever.  Now I VERY rarely have problems.  There is hope.  If they do reversal, it will not go away over night.  Your stomach has not been used for a little while.  I was a lot further out before they offered reversal to me, so it won't be AS BAD for you.  It is kind of like when you had you origional surgery..  Your stomach will have to get used to food all over again.  You can eat "normal food" a lot faster than before.  The longer out you go, the more your stomach will adapt.  I will still have some dumping, but I don't have to worry about eating away from home anymore.

Good luck.
