WHAT CAUSES A GALLBLADDER ATTACK The pain can come from a stone making its way down the biliary duct or bile tube toward the duodenum of the small intestine. It can also be caused by a back up of bile in the gallbladder (with or without stones) that causes it to swell from fullness causing discomfort.
Gallstones that do not cause symptoms are called asymptomatic, or silent, gallstones. Silent gallstones do not interfere with the function of the gallbladder, liver, or pancreas. If gallstones block the bile ducts, pressure increases in the gallbladder, causing a gallbladder attack.
