The document discusses conditions affecting the gallbladder. It describes the gallbladder's function of storing and releasing bile to aid digestion. Gallstones are formed when there is too much cholesterol or bilirubin in the bile and can cause blockages. Symptoms of gallstones include pain in the upper abdomen or back. Treatment options include medications to dissolve small stones, surgery to remove the gallbladder (cholecystectomy), or opening blocked ducts endoscopically. Complications arise if gallstones block important ducts, and may require hospitalization.
