Gallbladder Inflammation (Cholecystitis): Symptoms, Treatment & UK Online Doctor Guide

Cholecystitis is the inflammation of the gallbladder, a small, pear-shaped organ located beneath the liver on the right side of the abdomen. The gallbladder’s primary role is to store bile, a fluid produced by the liver that helps digest fats. In approximately 90% of cases in the UK, cholecystitis occurs when gallstones (cholelithiasis) block the tube leading out of the gallbladder, known as the cystic duct.

When this duct is blocked, bile builds up inside the gallbladder, leading to pressure, irritation, and eventually infection or inflammation. While less common, acalculous cholecystitis can occur without gallstones, often in patients who are already severely ill or recovering from major surgery. According to NHS and NICE guidance, prompt diagnosis is essential to prevent complications such as gangrene of the gallbladder or perforation.

The symptoms of cholecystitis can often be confused with severe indigestion or biliary colic, but the pain associated with inflammation is typically more persistent and severe. Key symptoms include:

• Steady, severe pain: Usually felt in the upper right or centre of the abdomen.
• Radiation: Pain that spreads to the right shoulder or the back between the shoulder blades.
• Tenderness: The abdomen feels very sore when touched, especially in the upper right side.
• Fever and chills: A high temperature (above 38°C) often indicates that an infection has developed.
• Nausea and vomiting: Many patients find they cannot keep food or drink down during an attack.
• Murphy’s Sign: A clinical indicator where pain increases significantly when you take a deep breath while a doctor presses on your gallbladder area.

The most frequent cause is the presence of gallstones. These hard deposits of digestive fluid can trigger inflammation if they become trapped in the neck of the gallbladder. However, other factors can lead to cholecystitis, including bile duct problems, tumours that obstruct bile flow, or certain viral infections.

In the UK, certain groups are at a higher risk of developing gallbladder issues. These include:

• Women: Especially those who have been pregnant, use hormonal contraception, or are on HRT.
• Age: People over the age of 40 are more prone to gallstones.
• Weight: Being overweight or obese increases the cholesterol levels in bile.
• Rapid weight loss: Losing weight very quickly can alter the chemical balance of bile, leading to stone formation.

If you suspect gallbladder inflammation, a healthcare professional will perform a physical examination. In the UK, NICE (National Institute for Health and Care Excellence) recommends specific pathways for suspected gallbladder disease. Diagnostic steps usually include:

Blood Tests

Tests are conducted to look for signs of inflammation (such as a high white blood cell count) and to check liver function. C-reactive protein (CRP) levels are often elevated in cholecystitis.

Ultrasound Scan

This is the primary imaging tool used in the NHS to diagnose cholecystitis. It is non-invasive and highly effective at showing gallstones, gallbladder wall thickening, and fluid buildup around the organ.

MRCP or CT Scans

In more complex cases, a Magnetic Resonance Cholangiopancreatography (MRCP) may be used to look for stones in the bile ducts that an ultrasound might miss.

Most patients diagnosed with acute cholecystitis require hospital admission for initial stabilisation. Treatment typically involves:

• Fast and Fluids: Patients are often kept 'nil by mouth' and given intravenous fluids to rest the gallbladder.
• Pain Management: Strong painkillers, such as paracetamol or non-steroidal anti-inflammatory drugs (NSAIDs), are administered via IV.
• Antibiotics: If an infection is suspected, antibiotics are given to clear the bacteria.

Once the inflammation has settled, the definitive treatment is usually the surgical removal of the gallbladder, known as a cholecystectomy. In the UK, this is most commonly performed as a laparoscopic (keyhole) surgery. Since the gallbladder is not an essential organ, you can lead a perfectly healthy life without it; the liver will simply drip bile directly into the small intestine.

If you are experiencing recurring abdominal discomfort, bloating, or mild pain under your right ribs after eating fatty meals, you should speak to a GP online. An online consultation is a convenient way to discuss your symptoms, review your medical history, and receive advice on the next steps.

While acute cholecystitis is an emergency, many people suffer from 'chronic cholecystitis' or biliary colic, where symptoms come and go. An online doctor can help differentiate between common gut concerns like IBS or acid reflux and potential gallbladder issues. They can provide referrals for blood tests or private imaging and offer guidance on dietary changes to manage symptoms while waiting for specialist review. Accessing an online doctor in the UK allows you to get a clinical opinion without the wait times often associated with local surgeries.
