Along the lines of looking at diet, one thing to track would be gluten intake and symptoms. There is some research correlating gluten intolerance to gall bladder issues and some that indicate that in some cases the problem wasn't gall bladder at all but undiagnosed gluten intolerance. I have a handful of GF friends who had their gall bladders removed in response to GI issues and major pain only to find the issues continued long after surgery and that resolved on a GF diet. For me personally, my pain/discomfort upon consuming gluten is just below my rib cage/diaphragm area, and is my primary symptom/response.

Gluten free since Nov '11 after non-celiac gluten sensitive diagnosis. Have had great improvement or total elimination of: migraines, bloating/distention, heartburn, cystic acne, canker sores, bleeding gums, eczema on elbows, dry skin and scalp, muscle cramps, PMS, hair loss, heart palpitations, fatigue. I'm amazed.
