2. Nausea And Vomiting
Since the gallbladder is involved with the digestive process, it stands to reason that any imbalance in the gallbladder can cause nausea. Conversely, not every bout of nausea has the gallbladder as its root cause. Also, not every bout of nausea occurs closely following a meal.
Vomitus from a gallbladder attack will be dark and green or yellow. Whole, undigested chunks of food will be included in the vomitus.
This means the bile never got close enough to the food to process the fats and cholesterol in it. Thus, it came right back up again.
