Acute cholecystitis is sudden swelling and irritation of the gallbladder. It causes severe belly pain.
Cholecystitis - acute; Gallstones - acute cholecystitis
The gallbladder is an organ that sits below the liver. It stores bile, which your body uses to digest fats in the small intestine.
Acute cholecystitis occurs when bile becomes trapped in the gallbladder. This often happens because a gallstone blocks the cystic duct, the tube through which bile travels into and out of the gallbladder. When a stone blocks this duct, bile builds up, causing irritation and pressure in the gallbladder. This can lead to swelling and infection.
Other causes include:
Some people are more at risk for gallstones. Risk factors include:
Sometimes, the bile duct becomes blocked temporarily. When this occurs repeatedly, it can lead to long-term (chronic) cholecystitis. This is swelling and irritation that continues over time. Eventually, the gallbladder becomes thick and hard. It does not store and release bile as well as it did.

Nonsurgical treatment includes:
You may need emergency surgery if you have complications such as:
If you are very ill, a tube may be placed through your belly into your gallbladder to drain it. Once you feel better, your provider may recommend that you have surgery.
Most people who have surgery to remove their gallbladder recover completely.
Untreated, cholecystitis may lead to any of the following health problems:
