Biliary Colic is typically caused by what?

Biliary colic is characterized by episodes of severe abdominal pain caused by the obstruction of bile flow, most commonly due to gallstones. When these stones form in the gallbladder, they can move and temporarily block the cystic duct or common bile duct, leading to increased pressure and pain in the biliary system. The pain usually occurs in the right upper quadrant and can radiate to the back or right shoulder.

Understanding the pathophysiology of biliary colic highlights the significance of gallstones as the primary cause, as they directly interfere with the normal flow of bile necessary for digestion. Other conditions, such as inflammation of the stomach lining, infections, or appendicitis, do not typically lead to the specific pattern and type of pain associated with biliary colic. This makes gallstone obstruction the clear and correct answer in this scenario.
