Cholecystitis: Symptoms, Causes, Types, Diagnosis and Treatment. Cholecystitis means inflammation of the gallbladder, a small, pear-shaped organ located below the liver. The gallbladder stores bile, a digestive fluid the liver makes that helps the body digest fats.

In most cases, cholecystitis happens when a gallstone blocks the cystic duct, the small tube that carries bile out of the gallbladder. When bile becomes trapped, the gallbladder can swell and become painful.

The pain can be quite severe and may come with nausea, vomiting or fever. Because untreated cholecystitis can sometimes lead to serious complications, persistent or severe upper abdominal pain should be evaluated by a doctor.

What Is Cholecystitis?

Cholecystitis is inflammation of the gallbladder. The most common form, called acute calculous cholecystitis, occurs when a gallstone blocks the cystic duct. The blockage prevents bile from leaving the gallbladder normally. 

This can cause pressure, irritation and inflammation inside the gallbladder. Less commonly, inflammation can develop without gallstones. This is known as acalculous cholecystitis and is more often seen in people who are seriously ill.

Types of Cholecystitis

Cholecystitis can develop suddenly or persist over time.

Acute Cholecystitis

Acute cholecystitis develops suddenly and can cause significant pain in the upper right side of the abdomen. Gallstones are the most common cause.

The pain may last for several hours and can be accompanied by nausea, vomiting or fever. Acute cholecystitis needs prompt medical assessment because complications can develop if the inflammation is not treated.

Chronic Cholecystitis

Chronic cholecystitis develops over a longer period and usually results from repeated episodes of gallbladder inflammation, often associated with gallstones.

Repeated inflammation can thicken or scar the gallbladder wall. Some people may have recurring discomfort after meals rather than one severe episode.

Acalculous Cholecystitis

Acalculous cholecystitis occurs without gallstones. It is less common but can be serious.

It is more likely to occur in people who are severely ill, have experienced major trauma or burns, have had prolonged fasting, or are receiving intensive hospital care.

Because symptoms may be less obvious in someone who is already very sick, doctors may need to use imaging and other tests to identify the condition.

What Are the Symptoms of Cholecystitis?

The symptoms can vary from person to person, but common signs include:

A doctor may also check for Murphy’s sign during a physical examination. This involves gently pressing on the upper right abdomen while asking the person to breathe in. Pain that makes the person stop inhaling can support the diagnosis, but it is not enough on its own to confirm cholecystitis.

What Does Cholecystitis Pain Feel Like?

Cholecystitis commonly causes pain in the upper right part of the abdomen, just below the ribs. The pain may be strong and persistent and can sometimes spread toward the right shoulder or back. It may occur after eating, particularly after a heavy or fatty meal.

Because several conditions can cause similar abdominal pain, including gallstones, pancreatitis, ulcers and appendicitis, severe or persistent abdominal pain should not be self-diagnosed.

What Causes Cholecystitis?

Who Is at Risk of Cholecystitis?

Because gallstones cause most acute cases, factors that increase gallstone risk can also increase cholecystitis risk.

These may include:

Rapid weight loss can increase the risk of gallstones, so crash diets and very restrictive diets are best avoided.

How Is Cholecystitis Diagnosed?

Doctors usually combine your symptoms, physical examination, blood tests and imaging results to determine whether you have cholecystitis.

CT Scan or Other Imaging

A CT scan may be used when doctors need more information or want to look for complications or another possible cause of abdominal pain. If the diagnosis remains uncertain, a HIDA scan (cholescintigraphy) may sometimes be used to check whether bile is flowing normally from the gallbladder. MRI or MRCP may also be used in selected cases.

How Is Cholecystitis Treated?

Treatment depends on the cause, severity of the inflammation and the person’s overall health.

Initial Treatment

If you have acute cholecystitis, you may need hospital treatment. Depending on your condition, doctors may recommend:

These measures help stabilize the person and control symptoms, but they do not remove a gallstone blocking the cystic duct.

Gallbladder Removal Surgery

When gallstones are responsible for acute cholecystitis, surgical removal of the gallbladder, called cholecystectomy, is a common definitive treatment. When appropriate, surgeons commonly use laparoscopic surgery. 

It involves several small cuts rather than one large abdominal incision. Surgery timing depends on the severity of the condition and the person’s overall health.

What Happens If Surgery Is Not Possible?

If someone is too unwell to undergo surgery immediately, doctors may use other approaches to control the inflammation and drain the gallbladder when necessary. 

The treatment plan depends on the person’s medical condition and the cause of the inflammation.

Can You Live Without a Gallbladder?

Yes. The gallbladder stores bile, but it is not an essential organ. After gallbladder removal, the liver continues to produce bile. Instead of being stored in the gallbladder, it flows directly into the small intestine through the bile ducts. Most people can return to a normal diet after recovery, although some people may temporarily notice looser or more frequent stools.

What Are the Complications of Cholecystitis?

Without appropriate treatment, cholecystitis can sometimes lead to serious complications.

These may include:

What Should You Eat If You Have Gallbladder Problems?

Diet can help you manage symptoms, but diet alone cannot treat acute cholecystitis or remove a blocked gallstone.

If your doctor recommends dietary changes, you may find it helpful to:

A healthy eating pattern and gradual weight management may also help reduce the risk of gallstones.

When Should You See a Doctor?

Do not ignore severe or persistent abdominal pain.

Seek prompt medical care if you have:

These symptoms can indicate a gallbladder or bile duct problem that needs medical evaluation. If the pain is severe, sudden or worsening, seek emergency medical attention rather than trying to manage it at home.

Conclusion

Cholecystitis is inflammation of the gallbladder, and gallstones blocking the cystic duct are the most common cause.

The condition can cause persistent pain in the upper right abdomen, nausea, vomiting and sometimes fever. Doctors usually diagnose it using a combination of symptoms, physical examination, blood tests and imaging, with ultrasound commonly used as the first imaging test.

Treatment depends on the severity and cause. Acute cholecystitis caused by gallstones often requires hospital treatment and, when appropriate, gallbladder removal surgery. Getting medical attention early can help reduce the risk of complications.
