In my case I was found to have a gallstone - I was having occasional bouts of serious pain in the upper right abdominal region that were becoming more frequent. Ultrasound revealed gallstone.

But in the couple of weeks before I could get the ultrasound I was essentially eating a vegan diet because I wasn't sure what was causing the pain and I wanted to just concentrate on only eating plants to minimize possible triggers. And then when the results came back and the surgeon told me it was time to schedule the surgery, I realized that I hadn't had any pain on my minimal diet. And so decided to give veganism a try for a month or so to see what would happen - and I continued to have no pain.

I think what it comes down to is that some animal fats cause the gallbladder to contract more vigorously - especially red meat, eggs and dairy in my case would trigger pain. I've heard about the issue you're talking about as it's been suggested that since you no longer have vigorous contractions of the gallbladder the gall tends to pool up there. On the other hand I've also heard bitter foods and beets help with this issue.
