Learn About Gallstone Treatment Options and What to Expect

Understanding Gallstones and Why Treatment Matters

Gallstones are hard deposits that form inside the gallbladder, a small organ located beneath the liver on the right side of your abdomen. The gallbladder stores bile, a digestive fluid that helps break down fats from food. When bile becomes imbalanced, cholesterol and other substances can crystallize and form stones. These stones range in size from tiny grains of sand to as large as golf balls.

According to the National Institutes of Health, about 10 to 15 percent of adults in the United States have gallstones, though many people never know they have them. Gallstones develop more commonly in people over age 40, women, those who are overweight or obese, and people with a family history of gallstones. Some research suggests that rapid weight loss and certain medications can also increase risk.

What makes gallstones important to understand is that while many people carry them without problems, others experience significant pain and complications. When a gallstone blocks the bile duct, it can trigger a painful attack. These attacks often happen after eating fatty foods and can last from 30 minutes to several hours. Beyond pain, blocked bile ducts can lead to inflammation of the gallbladder (cholecystitis), infection, or pancreatitis—inflammation of the pancreas—which are serious medical concerns.

The decision to pursue treatment depends on whether you have symptoms. People with "silent" gallstones—those that cause no pain or problems—may never need treatment. However, understanding your options helps you and your doctor make informed decisions about your health. Treatment ranges from lifestyle changes to medication to surgery, and each approach has different benefits and considerations.

Practical takeaway: If you have been diagnosed with gallstones, keep a record of any symptoms you experience, including when attacks occur and what foods trigger them. This information helps your doctor determine which treatment approach may work best for your situation.

Watchful Waiting: When You Might Not Need Immediate Treatment

Watchful waiting, also called conservative management, is an approach where you and your doctor monitor gallstones without starting active treatment. This strategy is appropriate for most people with silent gallstones—those that do not cause pain or other symptoms. Research published in medical journals shows that only about 2 to 3 percent of people with silent gallstones develop symptoms each year, meaning many may never need intervention.

During watchful waiting, your doctor may recommend periodic ultrasound exams to check that stones remain stable and have not caused complications. You would also report any new symptoms that develop. This approach allows time to see whether your body tolerates the stones without problems. For some people, watchful waiting lasts for years without any need for further intervention.

However, watchful waiting is generally not recommended for certain groups. People with diabetes and gallstones face higher risks of serious complications, so doctors typically recommend treatment even if symptoms have not yet appeared. Similarly, if gallstones are unusually large (greater than 3 centimeters), if the gallbladder wall has become calcified ("porcelain gallbladder"), or if gallstones are found alongside bile duct stones, active treatment usually becomes necessary. People who plan to have weight loss surgery may also benefit from having gallstones treated first, since rapid weight loss after surgery can increase gallstone formation.

The watchful waiting approach reduces unnecessary medical procedures and allows your body to function normally if it can. Many people never experience symptoms and live their entire lives without knowing they had gallstones or requiring treatment.

Practical takeaway: If your doctor recommends watchful waiting, ask about warning signs that would mean you should seek care right away—such as severe right-sided abdominal pain, fever, yellowing of skin or eyes, or persistent nausea. Knowing these signs helps you catch complications early.

Medication Options for Gallstone Management

Certain medications can dissolve gallstones, though this approach works in only a limited number of cases. Ursodeoxycholic acid (also called ursodiol) is an oral medication that works by reducing the amount of cholesterol your liver produces and by helping to dissolve existing cholesterol stones. This medication only works on stones composed mainly of cholesterol, not on pigment stones or calcified stones. Studies show that ursodeoxycholic acid successfully dissolves gallstones in about 30 to 50 percent of patients who take it, though the process typically takes six months to two years.

Medical literature indicates that medication works best for people who meet specific criteria: gallstones smaller than 20 millimeters in diameter, a functioning gallbladder that contracts normally, and liver function that is normal. Patients must be able to take the medication consistently, often for extended periods. The drug is taken by mouth, usually in divided doses throughout the day, which makes it convenient compared to surgical approaches.

A significant limitation of medication-based treatment is that gallstones often return after the drug is stopped. Studies suggest that about half of people who had their stones dissolved by medication will develop new stones within five years. For this reason, some people stay on a maintenance dose of the medication long-term. Ursodeoxycholic acid can also be used to prevent gallstone formation in people at high risk—such as those undergoing rapid weight loss—though this preventive use is not its primary application.

Other medications may help manage symptoms during watchful waiting. Anti-inflammatory drugs and antispasmodics can reduce pain during gallstone attacks, though they do not treat the underlying stones. Your doctor can discuss which medications might be appropriate for your specific situation.

Practical takeaway: If medication is being considered, work with your doctor to confirm that your stones are the type that respond to medication treatment. Ask about the expected timeline for results and what to do if stones return after treatment ends.

Extracorporeal Shock Wave Lithotripsy: Breaking Stones Without Surgery

Extracorporeal shock wave lithotripsy (ESWL) is a procedure that uses focused sound waves to break gallstones into smaller pieces. The word "extracorporeal" means the procedure occurs outside the body, and "lithotripsy" refers to stone-breaking. This approach offers an alternative to surgery for people who want to avoid operating room procedures or who may not be good candidates for surgery due to other health conditions.

During an ESWL procedure, you lie on a table while a device called a lithotripter directs high-energy sound waves at your gallstones. The sound waves create shock waves that pass through your skin and body tissue to reach the gallstones, breaking them into smaller fragments. The procedure typically takes 45 minutes to an hour. Most facilities perform ESWL as an outpatient procedure, meaning you go home the same day. Local anesthesia or sedation is usually given to keep you comfortable during the procedure.

Success rates for ESWL vary depending on stone characteristics. The procedure works best for people with a small number of stones that are not too large and are not calcified. According to medical data, stone clearance rates range from 50 to 80 percent depending on patient selection. After ESWL, the broken stone fragments typically pass into the small intestine through the bile duct. Some patients take ursodeoxycholic acid medication after ESWL to help dissolve remaining fragments.

ESWL is not widely available because many hospitals and imaging centers have discontinued offering it as other treatment options have become more refined. Additionally, gallstones can recur after ESWL treatment. Insurance coverage varies significantly by region and insurance plan. Possible complications include pancreatitis and bile duct obstruction, though these are uncommon when the procedure is performed correctly.

Practical takeaway: If ESWL interests you, first determine whether facilities in your area offer this procedure and whether your insurance covers it. Ask your doctor whether your stone type and size make you a good candidate.

Gallbladder Removal Surgery: The Most Common Definitive Treatment

Cholecystectomy—removal of the gallbladder—is the most common treatment for symptomatic gallstones. Once your gallbladder is removed, gallstones cannot form, making this a permanent solution. According to the American College of Gastroenterology, approximately 800,000 cholecystectomies are performed annually in the United States, making it one of the most frequently performed surgical procedures.
