Mays The gallbladder is a small organ that sits underneath the liver. It contains bile and digestive juice, and when you eat, the digestive juice releases from the gall bladder to help digest your food. Gallstones are not actually stones, they're solid material that form within the gallbladder that can lead to symptoms.

Gallstones can develop from patient's genes, their genetic makeup. They're more common in female than male. Other causes of gallstones include obesity and then diet. Whenever you do develop symptoms, the pain in your abdomen, the right upper abdomen, nausea, discomfort after eating, an ultrasound of the gallbladder will help diagnose the gallstones.
