If I may offer one bit of advice here. My significant other had her GB removed 3 years ago this month. After having numerous problems since then, we finally got to a gastro in Chicago who suggested that although the test results on her GB showed that it was only functioning at a 10% level, it didn't necessarily mean that she needed to have her GB removed.
We are both kicking ourselves for not getting a second opinion on her condition and a confirmation on the need for surgery.
Best of luck!
