What are the causes of your gallbladder to be inflamed?

Possibly stones: Gallstones can cause gallbladder inflammation--but also things like cholesterol buildup in the wall or bacterial infection. If an ultrasound doesn't show stones a nuclear scan--hyda scan--can show if it's working like it should.

Stasis: Problems with the gb emptying whether it is due to obstruction from stones or lack of inherent contractility, it is bile sitting in the gb and not draining properly that can set a patient up for inflammation. Stones sitting in the gb will also cause bile to build up in the gb and can contribute to stasis without causing overt obstruction.
