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.
A gallbladder attack may occur after a large meal but can also occur from blockage from gallstones. It may start as a feeling of indigestion and move on to more intense pressure in the stomach and in some instances chest pains that may feel like a heart attack. The duration of these symptoms can be a few minutes to several hours.
