I do not have a gallbladder. is nausea sometimes a symptom of not having one?

Nonspecific symptom: Nausea is one of those non-specific complaints that need to be viewed in the context of other symptoms & signs. Nausea may derived from the brain (concussion, brain contusion, subdural hematoma, life-threatening bleed, tumor, seizure), any part of the gut (stomach ulcer, gastroparesis, outlet delay or blockage, infection, etc.), the kidneys/ bladder, the female organs...You get the point. See doc.
