I don't have a gallbladder and was taking elderberry lozenges every day for like a month or more and ate sausages every other day for like a week i have had upset stomach neusea diarrhea since last month could it be elderberry lingering and grease???

Upset stomach: The elderberry is certainly out of your system after a week. Return to a bland diet - rice, bananas, applesauce and toast is a time honored one for diarrhea and let your gastrointestinal system re-equilibrate as it definitely will.

Stomach problems: Difficult to say for sure but possible. Get on a healthy diet with fresh fruits and vegetables and good hydration with water. Exercise regularly. Avoid caffeine, oily food and alcohol until symptoms improve. If symptoms persist please consult a physician.
