When the gallbladder becomes inflamed, a digestive system disease called cholecystitis can occur. There are two common types of cholecystitis: acute and chronic. Acute cholecystitis is manifested by rapid inflammation of the gallbladder, chronic is when the gallbladder remains inflamed for a long period of time. Sometimes the gallbladder has a sensitivity to certain foods such as full-fat dairy products, red meat, fatty or fried foods. The gallbladder can become inflamed due to several factors. Tumors can cause cholecystitis because they can push against the gallbladder or cause blockage of the cystic duct. An acute injury to the gallbladder can also cause cholecystitis. Road accidents and abdominal trauma can damage the gallbladder, causing it to swell. Certain types of bacteria can cause infection and inflammation of the gallbladder, including: strep, E-coli, and salmonella are some of the most common. These bacteria can also cause an infection within the gallbladder that needs to be treated. Although injury, infection, and pressure can cause cholecystitis, 80 percent of people develop cholecystitis due to gallstones. The gallbladder is responsible for producing bile which aids in digestion. Bile contains both fat and cholesterol. When the bile in the gallbladder contains too much fat or cholesterol, it can harden into small, stone-like pebbles. Additionally, when a gallbladder has abnormal function, it can cause it to slowly empty its contents. This can cause the cholesterol to harden into small, stone-like pebbles. These stones can become large enough to block the gallbladder ducts causing them to swell. Stones can also build up in the gallbladder and reduce its efficiency in digesting fat.
