Why a small stone in your gallbladder can trigger a life-threatening emergency

In short: Cholecystitis is more than just a stomachache. When a gallstone blocks the duct leading from your gallbladder, trapped bile causes dangerous pressure and inflammation. If left untreated, this can lead to tissue death, organ rupture, and systemic infection, turning a common digestive issue into a critical medical crisis.

The gallbladder is a small, pear-shaped organ tucked under the liver that stores bile, a fluid essential for digesting fats. Acute cholecystitis occurs when the flow of this bile is obstructed, most commonly by a gallstone—a hardened deposit of cholesterol and salts. In about 95% of cases, this blockage occurs at the cystic duct, the gallbladder's main exit. As bile builds up, the organ swells, causing intense, persistent pain in the upper right abdomen that often radiates toward the right shoulder.

While calculous cholecystitis (caused by stones) is the most frequent form, a rarer and often more severe version called acalculous cholecystitis can occur without stones. This type is typically a complication of serious illness, major surgery, trauma, or burns, where reduced blood flow or systemic infection damages the gallbladder tissue. Regardless of the cause, the condition is diagnosed through physical exams like Murphy’s sign—where pain spikes during deep inhalation—and confirmed via ultrasound.

If not treated promptly with fasting, intravenous fluids, and antibiotics, the consequences can be dire. Severe inflammation can lead to gangrenous cholecystitis, where tissue dies, or perforation, where the gallbladder tears and spills infected material into the abdominal cavity. Emergency surgery, or cholecystectomy, is often required to remove the organ entirely. While the gallbladder is useful for digestion, it is not essential; the liver continues to produce bile, allowing most patients to lead a normal life post-recovery.
