Cholecystitis - chronic
Chronic cholecystitis is long-standing swelling and irritation of the gallbladder.
Chronic cholecystitis is usually caused by repeated attacks of acute cholecystitis. This leads to thickening of the gallbladder walls. The gallbladder begins to shrink and eventually loses the ability to perform its function, which is concentrating, storing, and releasing bile.
The disease occurs more often in women than in men. The incidence increases after age 40. The main risk factors include the presence of gallstones (in which case, the symptoms are due to gallstones).
