Biliary Dyskinesia and Right-Side Back Pain After Eating – What Causes What?

Hi! I’ve been struggling with pain on the right side of my back that often occurs after eating. All my imaging shows no stones or inflammation in the gallbladder, and my bloodwork is completely normal, which makes this even more confusing.

I’ve been diagnosed with EPI (exocrine pancreatic insufficiency) and SIBO (small intestinal bacterial overgrowth), but I suspect I might also have issues with my gallbladder, possibly biliary dyskinesia. The problem is, I haven’t been able to do a HIDA scan since it’s not available in Sweden.

I’m trying to understand what’s causing what:

Could EPI cause biliary dyskinesia, or is it the other way around?

Is SIBO playing a role here?

Could biliary dyskinesia be the root of my issues, even without stones or inflammation?

I’m feeling really frustrated and stuck, as I can’t seem to solve this puzzle. Has anyone experienced something similar or have advice on how to investigate this further?

Thanks in advance!
