Thanks for posting your query
The term "contracted gallbladder" can refer to two different situations. The first occurs following a meal or after maneuvers that cause the muscle of the gallbladder to contract, for example, ingestion of fat or injection intravenously of the hormone that is responsible for causing the gallbladder to contract. In either case, the gallbladder empties, becomes smaller, and is said to be contracted. This is the normal situation. The second situation is when the gallbladder is diseased, specifically when there has been inflammation, for example, due to gallstones, that has resulted in scarring of the gallbladder. Scarring causes the gallbladder to become smaller, for example, contracted, and the gallbladder no longer functions normally. The "contraction" in the latter situation is clearly different from the "contraction" in the first.
