In short
Gallstones are extremely common and often cause no trouble at all, but when they block the flow of bile, the resulting pain and lab changes usually prompt a conversation about surgery.

What Gallstones Are and Who Gets Them
Gallstones are hardened deposits, usually made mostly of cholesterol or sometimes bilirubin, that form inside the gallbladder, the small organ that stores bile used to digest fat. They range from tiny, gravel-like particles to stones the size of a golf ball, and many people have them without ever knowing.
Risk rises with age, being female, obesity, rapid weight loss, pregnancy, a family history of gallstones, and certain medications including some hormone therapies. People with diabetes or conditions affecting bile composition also carry higher risk. Most gallstones, though, form for reasons that combine several of these factors rather than one clear cause.
02
When Gallstones Cause Symptoms
Many gallstones stay silent for a lifetime and are found incidentally on imaging done for another reason. When they do cause trouble, it's typically because a stone blocks the duct leading out of the gallbladder, causing sudden, intense pain in the upper right or center of the abdomen, often after a fatty meal, sometimes spreading to the back or right shoulder blade.
Nausea, vomiting, and pain lasting more than a few hours are common with a blocked duct. If a stone blocks the bile duct further down, on the way to the intestine, it can also cause jaundice, a yellowing of the skin and eyes, along with dark urine and pale stools, which signals a more urgent problem.
03
How Doctors Confirm It
Ultrasound of the abdomen is the standard first test and reliably shows gallstones sitting in the gallbladder. Blood tests add important context: bilirubin and alkaline phosphatase tend to rise when a stone is blocking bile flow, and sgpt/ALT can rise if the liver itself is under strain. Lipase is checked as well, since a gallstone can occasionally trigger pancreatitis if it blocks the shared duct near the pancreas.
The pattern across these tests, rather than any single number, helps a clinician judge whether a stone is simply present or actively causing a blockage that needs prompt attention. Additional imaging, such as an MRI-based scan of the bile ducts, is sometimes used when the picture isn't fully clear from ultrasound alone.
04
When Surgery Comes Up
Gallstones that never cause symptoms usually don't need treatment at all. Once they cause pain or a blockage, though, removing the gallbladder, most often through a minimally invasive laparoscopic procedure, is the standard recommendation, since gallstones that have caused one episode are likely to cause another. The gallbladder is not an organ the body needs after it's removed; digestion adapts.
If a stone is blocking the main bile duct, a procedure to remove it endoscopically is often done before or alongside gallbladder removal. Medication to dissolve stones exists but works slowly and only for specific stone types, so it's used far less often than surgery, mainly for people who aren't good surgical candidates.
05
Living With or Without a Gallbladder
Anyone with known, silent gallstones can generally eat normally, though a very fatty meal occasionally triggers mild discomfort in some people. Sudden, severe abdominal pain, fever, or yellowing skin should prompt urgent evaluation rather than waiting, since a blocked bile duct can lead to infection if left unaddressed.
After gallbladder removal, most people resume a normal diet within weeks, sometimes with looser stools for a period as the body adjusts to bile flowing more continuously rather than being stored and released. Long-term restriction of fatty foods usually isn't necessary once recovery is complete.
