The main cause of http://gallstones-gallbladder.blogspot.com/2010/06/patients-with-these-problems-are-common.html is gallstones. These are small deposits of minerals that can block the release of bile from the liver. During an attack, the upper part of the abdomen becomes highly painful and can spread to the lower back. A gallstone needs to either be surgically removed or otherwise broken up using various tools such as sonic devices.

Another main cause of gallbladder pain stems from an intolerance to
certain foods. The American Medical Association has shown that a number
of different types of foods will essentially cause allergic reactions.
These include fatty meats, dairy, eggs and highly-acidic fruits. A
person suffering from gallbladder pain should maintain a diet high in
fish, whole grains and green vegetables.

Other forms of digestive system problems can also lead to symptoms
involving the gallbladder. A person who suffers from liver disease often
suffers from gallbladder pain as well. In addition, gallbladder
surgery problems can sometimes be mistaken for other digestive disorders such as
an acute pancreatitis.
