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.
The most common problem caused by gallstones occurs when a gallstone periodically blocks the cystic duct, which drains the gallbladder. It often causes bouts of pain that come and go as the gallbladder contracts and expands. The bouts of pain are usually severe and steady, lasting from 15 minutes to up to 6 hours.
