Cholecystitis or acute cholecystitis is the inflammation of your gallbladder. If this condition persists for a prolonged period of time or if you have repeated attacks, it is called chronic cholecystitis.
The gallbladder is a small, pear-shaped organ located under your liver. It stores bile made by the liver and sends it to the small intestine via the common bile duct (CBD) to aid in the digestion of fats. The CBD connects the liver, the gallbladder, and the pancreas to the small intestine. Gallstones blocking the CBD are the leading cause of cholecystitis. This blockage means that bile builds up in the gallbladder, and that buildup causes the gallbladder to become inflamed.
This is a serious condition. If not treated properly, the gallbladder could rupture. Treatment usually involves antibiotics, pain medications, or removal of the gallbladder.
