The gallbladder is a 4-inch-long, pear-shaped organ found under the liver in the upper right region of the abdomen. It stores bile, a compound produced by the liver to digest fat, and helps the body absorb fat-soluble vitamins and nutrients.
In a healthy gallbladder, this process happens painlessly. However, when blockage occurs in the gallbladder, or it stops functioning correctly, considerable pain and discomfort can occur.
Cholecystectomy is surgery to remove the gallbladder. A gallbladder may need to be removed if the organ is prone to troublesome gallstones, if it is infected, or becomes cancerous.
