A typical gallbladder attack lasts anywhere from 20 minutes to a few hours. The pain usually builds quickly, peaks, and then gradually fades as the gallstone shifts and bile starts flowing again. If your pain has lasted more than two hours or comes with a fever, that’s a different situation that needs emergency medical attention.
What Happens During an Attack
Your gallbladder stores bile, a digestive fluid made by your liver. When you eat, especially something fatty, your gallbladder contracts to push bile through a small duct into your small intestine. A gallbladder attack happens when a gallstone gets lodged in that duct during the squeeze, temporarily blocking bile from flowing out.
The pain you feel is your gallbladder contracting hard against that blockage. It’s not really “colic” in the way most people think of cramping that comes and goes. The pain tends to be steady and intense, centered in your upper right abdomen, and it often wraps around to your back. Some people feel it more in the center of their stomach, just below the breastbone. Nausea is common.
Attacks typically strike about 15 to 20 minutes after eating, particularly after greasy or fatty meals. The pain eventually subsides when the gallstone either passes through the duct or falls back into the gallbladder, restoring bile flow. Even after the sharp pain resolves, a mild ache in the area can linger for up to 24 hours.
When Pain Lasts Longer Than a Few Hours
A standard gallbladder attack that resolves on its own is called biliary colic. It’s painful but not dangerous. The concern is when the gallstone stays stuck long enough to cause an infection or inflammation of the gallbladder wall, a condition called acute cholecystitis. This is the critical distinction: biliary colic goes away, cholecystitis gets worse.
With cholecystitis, the pain doesn’t fade after a few hours. Instead, it intensifies and is joined by fever, rapid heart rate, and sharp tenderness in the upper right abdomen, especially when you take a deep breath. If the inflammation continues unchecked, it can lead to serious complications, including a perforation (hole) in the gallbladder wall or an infection that spreads to the abdominal lining. Most people who are treated for acute cholecystitis recover within a few days to a few weeks, but it requires medical intervention.
The two-hour mark is a practical threshold. If constant, severe pain has persisted beyond two hours, or if you develop a fever at any point, treat it as an emergency.
How Often Attacks Come Back
If you’ve had one gallbladder attack, there’s a meaningful chance you’ll have another. Research published in BMJ Open Gastroenterology found that among patients who didn’t have their gallbladder removed after an acute episode, the risk of another gallstone complication was 14% within six weeks, 19% within 12 weeks, and 29% within a year. The gallstones don’t dissolve on their own, so the underlying problem remains.
Attacks often follow a pattern. You may notice they happen after the same kinds of meals, at similar times of day, or with increasing frequency over months. Some people go long stretches between episodes, while others start having them weekly. The unpredictability is part of what makes the condition frustrating.
How Gallbladder Problems Are Diagnosed
An abdominal ultrasound is usually the first test. It can spot gallstones and signs of gallbladder inflammation quickly and without radiation. When ultrasound results are inconclusive, doctors may order a HIDA scan, which tracks the flow of bile from your liver through the ducts and into your small intestine using a small amount of radioactive tracer. A HIDA scan can reveal blockages, poor gallbladder function, or bile leaks that ultrasound might miss.
Blood tests can also help distinguish a simple gallstone episode from cholecystitis or other complications by checking for signs of infection and inflammation.
When Surgery Becomes the Recommendation
Gallstones that never cause symptoms generally don’t need treatment. But once you’ve had a symptomatic episode, surgical removal of the gallbladder (cholecystectomy) becomes the standard recommendation. Guidelines from the Society of American Gastrointestinal and Endoscopic Surgeons state that most patients with symptomatic gallstones are candidates for the procedure as long as they can tolerate general anesthesia.
The surgery is almost always done laparoscopically, through a few small incisions. Most people go home the same day or the next morning and return to normal activities within one to two weeks. Your body adjusts to life without a gallbladder by routing bile directly from the liver to the small intestine. Some people notice looser stools for a few weeks after surgery, but this typically resolves.
The logic behind recommending surgery after even a single attack is straightforward: the gallstones are still there, the recurrence rate is high, and each new episode carries a risk of progressing to cholecystitis or other complications. Waiting doesn’t make the problem smaller.
What to Do During an Attack
If you’re in the middle of what you believe is a gallbladder attack, stop eating and avoid lying flat, which can worsen the discomfort. Some people find that sitting upright or leaning slightly forward helps. Over-the-counter pain relievers can take the edge off mild episodes. Applying a warm (not hot) compress to your upper abdomen may also provide some relief.
Track how long the pain lasts and what you ate beforehand. This information is genuinely useful for your doctor in distinguishing biliary colic from other causes of abdominal pain. If the pain climbs past that two-hour mark, gets significantly worse, or is accompanied by fever, vomiting that won’t stop, or yellowing of your skin or eyes, go to the emergency room.
