👉 Cholecystolithiasis is a condition in which bile stones form within the gallbladder. These stones can block the flow of bile, causing pain or discomfort, nausea, and vomiting.

The symptoms of cholecystolithiasis typically start with a dull, painless feeling in the upper right quadrant of the abdomen (the "right side of your belly")
