What is acute cholecystitis? Acute cholecystitis is sudden inflammation of the gallbladder, most often caused by gallstones blocking bile flow. It typically causes sharp, persistent pain in the right upper abdomen that may radiate to the right shoulder, often with fever, nausea, or vomiting. While it requires prompt medical attention, it is highly treatable.
What are the next steps? Urgent evaluation usually involves an abdominal ultrasound and blood tests, followed by hospital care with IV fluids, pain control, and antibiotics. Early laparoscopic gallbladder removal (cholecystectomy) is the standard treatment when appropriate. Red flags such as jaundice, high fever, or worsening pain warrant immediate emergency care, while surgery may sometimes be delayed based on individual risk factors.
Not sure if your symptoms match? Because cholecystitis shares symptoms with conditions like ulcers, pancreatitis, and kidney stones, identifying it early matters. Take a free, instant, online Acute Cholecystitis symptom check to clarify what you're experiencing and confidently plan your next steps—before symptoms escalate.

Submit your own QuestionA sharp pain on the right side of your upper abdomen can be alarming. One possible cause is cholecystitis, a medical condition that requires prompt attention. Understanding what cholecystitis is, why it happens, and what to do next can help you respond calmly and appropriately.
This guide explains cholecystitis in clear, practical language using medically credible information from established clinical guidelines and research.
Cholecystitis is inflammation of the gallbladder. The gallbladder is a small, pear-shaped organ located under your liver on the right side of your abdomen. Its job is to store bile, a digestive fluid that helps break down fats.
When the gallbladder becomes inflamed, it can cause significant pain and other symptoms. In many cases, cholecystitis happens suddenly (called acute cholecystitis). Less commonly, it can develop gradually over time (chronic cholecystitis).
Acute cholecystitis is considered a potentially serious condition and often requires medical treatment.
The most common cause of cholecystitis is gallstones.
Gallstones are hardened deposits that form in the gallbladder. If a stone blocks the cystic duct (the tube that allows bile to flow out), bile builds up. This blockage causes:
This accounts for about 90–95% of acute cholecystitis cases.
In some cases, cholecystitis happens without gallstones. This is more common in people who:
This type is less common but can be more serious.
Risk factors that increase the chance of developing cholecystitis include:
Having risk factors does not guarantee you'll develop cholecystitis, but it increases the likelihood.
The most common symptom is sharp or steady pain in the upper right abdomen.
Unlike simple gallstone pain (biliary colic), which may come and go, pain from acute cholecystitis usually persists and worsens.
Seek immediate medical attention if you have:
These may signal complications.
Cholecystitis can range from mild to life-threatening.
If untreated, complications may include:
The good news: with prompt diagnosis and treatment, most people recover well.
Doctors use a combination of:
Ultrasound is typically the primary imaging tool because it effectively detects gallstones and gallbladder inflammation.
If you're experiencing persistent upper right abdominal pain and want to quickly assess whether your symptoms might indicate cholecystitis or another condition, try Ubie's free AI symptom checker to get personalized insights in just 3 minutes before speaking with a healthcare provider.
Treatment depends on severity, but most cases of acute cholecystitis require hospital care.
Initial treatment usually includes:
The standard treatment for acute cholecystitis is surgical removal of the gallbladder.
You can live normally without a gallbladder. The liver continues to produce bile, but it flows directly into the intestine instead of being stored.
If someone is too ill for surgery:
Mild inflammation may temporarily improve, but true acute cholecystitis generally does not resolve permanently without treatment.
Delaying care increases the risk of:
It's important not to ignore persistent right-sided abdominal pain, especially with fever.
While not all cases are preventable, you can lower your risk of gallstones and cholecystitis by:
These steps support overall digestive and metabolic health.
You should speak to a doctor promptly if you experience:
Cholecystitis can become serious quickly. If symptoms are severe, go to the emergency department rather than waiting for a routine appointment.
Do not attempt to self-diagnose or treat suspected cholecystitis at home.
Cholecystitis is inflammation of the gallbladder, most commonly caused by gallstones blocking bile flow. It often presents as sharp, steady pain in the upper right abdomen, sometimes accompanied by fever and nausea.
While it can sound intimidating, cholecystitis is treatable—especially when caught early. Most people recover fully after appropriate medical care, often including gallbladder removal.
If you're experiencing concerning abdominal symptoms and want guidance on possible causes and next steps, check your symptoms with Ubie's AI-powered tool to help you prepare for a conversation with a qualified healthcare professional.
Any condition involving severe abdominal pain can be serious or even life-threatening. If symptoms are intense, worsening, or accompanied by fever or jaundice, seek immediate medical care.
Prompt evaluation and treatment make all the difference.
