Gallstones: When They Need Treatment and When They Do Not

The short answer#

Most gallstones need no treatment. Around 8 in 10 people with gallstones have "silent" stones that cause no symptoms, and these are safely left in place. Only about 1 to 2 percent per year ever start causing trouble, and serious complications are rarer still. Treatment matters once stones cause repeated pain or block a duct. The standard fix is keyhole removal of the whole gallbladder (laparoscopic cholecystectomy), not the stones alone. Sudden severe belly pain lasting hours, especially with fever, persistent vomiting, or yellowing of the eyes or skin, is an emergency and should be assessed the same day.

Key points#

• Gallstones are common. They turn up in roughly 1 in 10 to 1 in 7 adults, and most people never know they have them.
• Silent (asymptomatic) stones are usually left alone. The yearly chance of them causing symptoms is low, about 1 to 2 percent, and most people with them never need surgery.
• The classic symptom is biliary colic: steady pain in the upper right abdomen or upper middle belly, often after a large or fatty meal, building over 15 to 60 minutes and easing within a few hours.
• Once stones cause one attack, more attacks are likely, which is why gallbladder removal is offered for symptomatic stones.
• Surgery is standard for symptomatic stones and for complications such as gallbladder inflammation (cholecystitis), duct stones, or gallstone pancreatitis.
• A few asymptomatic situations still warrant surgery, including very large stones (over about 3 cm) or a calcified "porcelain" gallbladder, mainly because of higher gallbladder cancer risk.
• Fever with jaundice and belly pain, or severe pain boring through to the back, points to cholangitis or pancreatitis, both emergencies.

What are gallstones, and why are they so common?#

Gallstones are hardened deposits that form in the gallbladder, a small pouch tucked under the liver that stores bile and squeezes it into the intestine to help digest fat. Stones form when bile holds too much cholesterol or too much of the pigment bilirubin, or when the gallbladder does not empty well. In high-income countries most stones are cholesterol-predominant. Pigment stones are more common when red blood cells break down faster than normal, a link we cover in our wider library on kidney, digestive, and blood health.

They are genuinely common. In the United States gallstones are present in roughly 14 percent of adults, and that figure has climbed over recent decades. Risk rises with older age, female sex, pregnancy, obesity, rapid weight loss, and a family history. The point that drives every treatment decision is simple: having stones is not the same as having a problem from them.

Asymptomatic versus symptomatic: why silent stones are usually left alone#

Up to 80 percent of people with gallstones have no symptoms. Clinicians do not rush to remove every silent stone because the numbers do not support it. Among people with silent stones, only about 1 to 2 out of 100 develop symptoms in a given year. Over five years roughly 10 in 100 develop symptoms, about 15 in 100 over a decade, rising toward roughly 20 in 100 by 15 to 20 years. Serious complications (a blocked duct, infection, or pancreatitis) are much less frequent, on the order of a fraction of a percent up to about 1 percent per year.

Put the other way around: to prevent one future gallbladder problem, you would have to operate on many people who would never have had one, each carrying the small but real risks of surgery and anesthesia. That trade-off, treating a picture on a scan rather than a person with a problem, is the same reasoning that shapes careful screening decisions elsewhere in medicine. See Cancer Screening: Weighing Earlier Detection Against Overdiagnosis for the broader logic. For most silent stones found by chance on an ultrasound or CT scan done for another reason, watchful waiting is the guideline-supported choice.

What does a gallbladder attack feel like?#

A gallbladder attack, or biliary colic, happens when a stone temporarily blocks the gallbladder outlet as the organ contracts. Despite the word "colic," the pain is usually steady rather than coming in waves. It sits in the upper right abdomen or the upper middle belly, can spread to the right shoulder blade or the back, and often begins within an hour of a large or fatty meal, frequently in the evening or overnight. It builds over 15 to 60 minutes, holds for a while, then fades over the next few hours, and is commonly paired with nausea.

Vague, long-running symptoms such as bloating, belching, or general indigestion are often blamed on gallstones but usually come from something else, so removing the gallbladder may not fix them. True biliary colic tends to repeat: after a first attack, most people have further episodes within a couple of years. That pattern is the practical reason to treat symptomatic stones rather than wait.

The useful distinction is colic versus complication.

Do gallstones need surgery, and who needs a cholecystectomy?#

For symptomatic gallstones, the standard treatment is laparoscopic cholecystectomy: keyhole removal of the whole gallbladder, not just the stones. Taking out only the stones does not work, because the gallbladder simply makes more. The operation is one of the more common procedures in adults, is frequently done as day surgery, and most people return to normal activity within about a week. The gallbladder is not essential. Bile flows straight from the liver into the intestine afterward, and any looser or more frequent stools are usually temporary.

Clear reasons to operate include:

• Recurrent biliary colic from stones.
• Acute cholecystitis, a sustained, inflamed, sometimes infected gallbladder.
• Stones that have passed into the common bile duct (choledocholithiasis), which occur in roughly 6 to 12 percent of people with gallstones and raise the risk of pancreatitis and duct infection. These are often cleared with ERCP, an endoscopic procedure that removes the duct stone, followed by gallbladder removal.
• Gallstone pancreatitis, with surgery timed once the acute episode has settled.

A minority of people without symptoms are still offered surgery, mainly to lower gallbladder cancer risk or where an attack would be especially dangerous. Examples include stones larger than about 3 cm, a calcified "porcelain" gallbladder, some gallbladder polyps, and specific settings such as people with hemolytic anemia having their spleen removed, or certain transplant candidates. Medicines that dissolve stones (ursodeoxycholic acid) work only on cholesterol stones, act slowly over months, and stones often return, so they are reserved for people who cannot have surgery.

When is gallbladder pain an emergency?#

Two complications turn gallbladder disease from painful into dangerous.

Acute cholangitis is infection of an obstructed bile duct. The classic combination is fever, jaundice (yellow eyes or skin), and upper right belly pain, known as Charcot triad. When confusion and low blood pressure are added, it signals septic shock. Cholangitis needs urgent antibiotics and prompt drainage of the duct, usually by ERCP. A blocked, jaundiced duct is not always caused by a stone; a tumor can produce the same picture, as discussed in Malignant biliary obstruction, so new painless jaundice always needs assessment.

Gallstone pancreatitis happens when a stone lodges where the bile and pancreatic ducts join, inflaming the pancreas. It causes severe upper belly pain that often bores through to the back, along with vomiting, and it can become life-threatening. It is one of the leading triggers of the wider condition covered in Acute pancreatitis. Both cholangitis and pancreatitis are reasons to go to an emergency department rather than wait for a routine appointment.

When to seek care#

Get urgent, same-day or emergency assessment if you have:

• Belly pain lasting more than about 5 to 6 hours, or pain that is severe.
• Fever or shaking chills alongside abdominal pain.
• Yellowing of the eyes or skin (jaundice).
• Tea-colored urine, or pale, clay-colored stools.
• Persistent vomiting, or being unable to keep fluids down.
• Severe upper abdominal pain spreading to the back.
• Confusion, a racing heart, or feeling faint with belly pain.

Shorter, milder attacks that settle on their own still deserve a non-urgent medical review, both to confirm the diagnosis and to decide whether treatment is needed.

Talk with a licensed clinician about your own symptoms, imaging, and treatment options.
