Most people with gallstones never know they have them. About 10% of adults in Europe carry gallstones, and in the U.S., over 20 million people between ages 20 and 74 have them. The majority of these stones sit quietly in the gallbladder without causing problems. So the real question isn’t just whether you have gallstones, but whether your symptoms point to gallstones that need attention.
What Gallstone Pain Actually Feels Like
The hallmark symptom is a specific type of pain called biliary colic. It’s a severe, gripping pain in the upper right side of your abdomen, just below your ribs. It often radiates to your back, between your shoulder blades, or to the lower tip of your right shoulder blade. Some people feel it more in the center of the upper abdomen, and in rarer cases, it can mimic chest pain or even show up on the left side.
This pain typically lasts between 20 minutes and 6 hours. That duration is one of the most useful clues. Pain that comes and goes in seconds or minutes is unlikely to be gallstones. Pain that persists beyond 12 hours suggests something more serious, like an inflamed gallbladder (cholecystitis) or a stone stuck in the bile duct. Nausea and vomiting frequently accompany the pain, and episodes often follow meals, particularly fatty ones. The pain can also wake you up in the middle of the night.
One important distinction: biliary colic isn’t really “colic” in the way most people think of it. The pain doesn’t come in sharp waves like intestinal cramps. It builds to a steady, intense plateau, holds there, then gradually fades. Many people describe it as the worst pain they’ve ever felt, strong enough to keep them from sitting still or finding a comfortable position.
How Gallstone Pain Differs From Other Conditions
Upper abdominal pain has many possible causes, and sorting gallstones from acid reflux or ulcers is something people commonly struggle with. A few patterns help.
Acid reflux produces a burning sensation behind your breastbone that often creeps up toward your throat. It gets worse when you bend over or lie down and is triggered by a wider range of foods: citrus, chocolate, coffee, alcohol, and spicy dishes. Gallbladder pain concentrates in the upper right abdomen and radiates to the back or shoulder, not up toward the throat. It’s provoked by fatty meals specifically, not by body position.
Stomach ulcer pain tends to be a gnawing or burning ache in the center of the upper abdomen. It often improves temporarily with eating (especially with antacids), then returns. Gallstone pain doesn’t respond to antacids and typically starts after eating rather than being relieved by it. If your pain follows this “eat, feel better, pain returns” cycle, an ulcer is more likely than gallstones.
Who Is Most Likely to Have Gallstones
Your risk profile can help you gauge whether gallstones are a plausible explanation for your symptoms. The traditional shorthand is the “four Fs” (female, forty, fertile, fat), but the actual picture is broader. Women develop gallstones at roughly twice the rate of men overall, and three times the rate during their reproductive years. By age 65, about 30% of women have gallstones. By 80, the prevalence reaches 60% in both sexes.
In Western countries, about 75% of gallstones are cholesterol stones, driven by metabolic factors: obesity, insulin resistance, diabetes, high-fat and high-sugar diets low in fiber, and physical inactivity. Rapid weight loss is a well-established trigger because it saturates bile with cholesterol, and prolonged fasting reduces gallbladder contractions, letting stones form. Hispanic individuals and Indigenous Americans have notably higher rates, with some Indigenous populations reaching 70% prevalence. Genetics, hormonal factors, and even the gut microbiome all play a role.
How Doctors Confirm Gallstones
If your symptoms suggest gallstones, the first test is almost always an abdominal ultrasound. It’s painless, fast, uses no radiation, and is remarkably good at its job. Ultrasound picks up gallstones with 100% sensitivity in clinical studies, meaning it catches virtually every stone that’s there. A CT scan, by comparison, only detects about 79% of gallstones because many stones don’t show up well on CT. This is why ultrasound is the standard first step, not a CT scan, even though CT is often the default imaging for abdominal pain in emergency settings.
Your doctor will also likely order blood work. These tests don’t detect gallstones directly, but they reveal whether a stone is causing trouble. When a stone blocks the bile duct, levels of bilirubin (which causes jaundice), alkaline phosphatase, and an enzyme called GGT rise in a pattern that signals obstruction. Within 24 hours of a blockage, liver enzymes also spike. If your doctor suspects a stone has triggered pancreatitis, they’ll check lipase levels. A lipase reading at three or more times the normal upper limit strongly suggests acute pancreatitis.
If ultrasound is inconclusive or your doctor suspects stones in the bile ducts rather than the gallbladder itself, two additional imaging options come into play. An MRCP is a specialized MRI that provides detailed images of the bile ducts without any needles or dye injections. A HIDA scan takes a different approach entirely: it tracks a small amount of radioactive tracer as it moves through your liver, bile ducts, and gallbladder, revealing whether the gallbladder is functioning normally. HIDA scans are particularly useful when cholecystitis is suspected but ultrasound hasn’t been definitive.
What Happens During a Physical Exam
Before ordering any imaging, your doctor will likely perform a hands-on check called Murphy’s sign. While you take a deep breath in, the doctor presses on the right side of your abdomen just below the ribs. If your inflamed gallbladder descends during the breath and contacts the examiner’s hand, you’ll feel a sharp pain and instinctively stop breathing in. A positive Murphy’s sign is highly suggestive of acute cholecystitis, with one study showing it was 97% sensitive and correctly predicted an inflamed gallbladder 93% of the time. It’s less reliable in people over 70, where its sensitivity drops to around 48%.
Silent Gallstones and Whether to Treat Them
Many people discover gallstones incidentally during imaging for something else entirely. If those stones have never caused symptoms, current guidelines are clear: surgery offers no benefit. The World Gastroenterology Organisation has laid out the math explicitly. Out of 10,000 people with silent gallstones, roughly 200 would develop serious complications over 10 years, leading to about 15 deaths. But if all 10,000 had their gallbladders removed preventively, between 10 and 50 would die from surgical complications. The risk of surgery matches or exceeds the risk of leaving the stones alone.
Even a single uncomplicated episode of gallstone pain doesn’t automatically mean you need surgery. The decision depends on how frequent and severe your episodes are, whether complications have developed, and your overall health.
Warning Signs That Need Immediate Attention
Most gallstone episodes, while painful, resolve on their own. But certain symptoms signal complications that require emergency care: pain so severe you can’t sit still or find any comfortable position, yellowing of your skin or the whites of your eyes, and high fever with chills. Jaundice means a stone is blocking the bile duct. Fever with chills suggests infection. And sudden, severe pain in the center of your upper abdomen that bores straight through to your back, especially with vomiting, may indicate a stone has triggered pancreatitis. Any of these combinations warrants an emergency room visit, not a scheduled appointment.
