They cannot pass through your organs into the rest of the body. There is a small duct from the gallbladder to the small intestines. Small stones can form in this area and grow in size over time, possibly forming a block that inhibits the gallbladder from secreting bile into your digestive tract.

Large gallstones will get stuck in this duct and cause severe pain, amongst other symptoms. This requires medical attention.
