I had my gallbladder taken out 13 years ago and I still have minor pain and "dumping" issues.
The worst pain that I have occurs when I bend completely over toward the front and I have a sharp, stabbing pain right where my gallbladder used to be. So, I just don't bend completely over unless I have to. I can go for a while, then I forget about it, sit down and bend over to tie my shoes or something and there it goes! It really is like a bad pain and charlie horse combined. Doctors have never figured out what causes it.
As for the dumping. I have more issues with sugar and raw foods. Fat doesn't seem to bother me that much. But I don't eat much meat and I never eat mayo (didn't before the surgery, either)...so they may very well cause me some problems if I ate more of those things.
I have recently begun having strange "reactions" (I hesitate to call it a full blown allergy) to certain preservatives and seasonings. I can't eat anything spicy unless I want a dumping episode. (and I live in Louisiana of all places...it's hard to explain at restaurants sometimes that you don't want ANY seasoning).
My biggest problem has been weight gain and trying to lose weight. It takes very little for me to gain weight and major effort to lose even a little. I gained 50 lbs. within 2 months of having my gallbladder removed and I haven't been able to get rid of it in the 13 yrs. since. Doctors are also baffled by this.

At least I haven't really gained any more weight in those years, I just can't lose what I need to.
Sorry I don't have any answers for you. Just wanted to let you know that others have these issues after gallbladder surgery and the doctors (at least the ones I've dealt with) seem to have the attitude that you should just be glad to be rid of it, that it didn't kill you, the pain and dumping are minor things, etc.
Hope you feel better soon.
