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 first attack of gallstone symptoms is often not severe. Serious complications (such as a blocked duct) rarely occur. So you and your doctor may decide to delay treatment to see whether symptoms go away on their own. This is especially true if your doctor is not sure that the symptoms were caused by gallstones.
