Acute cholecystitis is a sudden swelling and irritation of the gallbladder. It causes severe belly pain.

Cholecystitis - acute
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. This is the tube that 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:
- Serious illnesses such as HIV or diabetes
- Tumors of the gallbladder (rare)
Some people are more at risk for gallstones. Risk factors include:
- Being female
- Hormone therapy
- Older age
- Being Native American or Hispanic
- Losing or gaining weight rapidly
Sometimes the bile duct becomes blocked temporarily. When this occurs repeatedly, it can lead to chronic cholecystitis. This is swelling and irritation that continues over time. Eventually, the gallbladder becomes thick and hard. It also does not store and release bile as well.
The main symptom is pain in the upper right side or upper middle of your belly that usually lasts at least 30 minutes. You may feel:
- Sharp, cramping, or dull pain
- Steady pain
- Pain that spreads to your back or below your right shoulder blade
Other symptoms that may occur include:
- Clay-colored stools
- Nausea and vomiting
- Yellowing of skin and whites of the eyes (jaundice)
Exams and Tests
A physical exam will show that it hurts to touch your belly.
Your doctor may order the following blood tests:
Imaging tests can show gallstones or inflammation. You may have one of these tests:
- Abdominal ultrasound
- Abdominal CT scan
- Abdominal x-ray
- Oral cholecystogram
- Gallbladder radionuclide scan
If you have severe belly pain, seek medical attention right away.
In the emergency room, you'll be given fluids through a vein. You also may be given antibiotics to fight infection.
Cholecystitis may clear up on its own. However, if you have gallstones, you will probably need surgery to remove your gallbladder.
Nonsurgical treatment includes:
- Antibiotics to fight infection
- Low-fat diet (if you are able to eat)
- Pain medicines
You may need emergency surgery if you have complications such as:
- Gangrene (tissue death)
- Perforation (a hole that forms in the wall of the gallbladder)
- Pancreatitis (inflamed pancreas)
- Persistent bile duct blockage
- Inflammation of the common bile duct
If you are very ill, a tube may be placed in your gallbladder and through your skin to drain it. Then, once you are feeling better, you may have surgery.
Most people who have surgery to remove their gallbladder recover completely.
- Empyema (pus in the gallbladder)
- Injury to the bile ducts draining the liver (may occur after gallbladder surgery)
- Peritonitis (inflammation of the lining of the abdomen)
When to Contact a Medical Professional
Call your health care provider if:
- Severe belly pain does not go away
- Symptoms of cholecystitis return
Removing the gallbladder and gallstones will prevent further attacks.
