Gallstones / Cholelithiasis

Introduction

If you have been told you have gallstones, you are not alone. Gallstones are one of the most common digestive conditions in the world, and many people carry them for years without ever knowing. For others, gallstones cause sudden, severe pain or lead to complications that need urgent care.

This article is written for people who have been diagnosed with gallstones, or who are being investigated for them, and who want to understand what comes next. It covers what gallstones are, why they form, when they need treatment, what the surgical and non-surgical options look like, and what life is like after the gallbladder is removed.

The medical name for having gallstones is cholelithiasis. You will see both terms used — they mean the same thing.

What Are Gallstones?

The gallbladder is a small, pear-shaped organ that sits just under the liver, on the right side of the upper abdomen. Its job is to store bile, a yellow-green digestive fluid made by the liver. When you eat a meal — especially one containing fat — the gallbladder squeezes bile into the small intestine through a thin tube called the common bile duct. Bile helps the body digest fats and absorb certain vitamins.

Gallstones are hard deposits that form inside the gallbladder. They can range in size from a grain of sand to as large as a golf ball. Some people have one large stone; others have dozens of small ones. Most gallstones fall into two chemical types:

• Cholesterol stones are the most common type, especially in many Western and Asian populations. They form when bile contains too much cholesterol for the bile to keep dissolved.
• Pigment stones are smaller and darker. They form when bile contains too much bilirubin, a waste product from the breakdown of red blood cells. Pigment stones are more common in people with certain blood disorders, liver disease, or chronic infections of the bile ducts.

Many people have mixed stones that contain both cholesterol and pigment material.

Gallstones can stay quietly in the gallbladder for years. Problems begin when a stone moves and blocks the flow of bile — for example, when it lodges in the neck of the gallbladder or slips into one of the bile ducts.

Types of Gallstone Disease

Doctors usually divide gallstone-related problems into a few clinical patterns. Understanding which one applies to you helps make sense of the treatment plan being discussed.

Asymptomatic (Silent) Gallstones

Most people with gallstones never feel them. The stones are often discovered by chance during an ultrasound or CT scan done for another reason. This is called silent or asymptomatic cholelithiasis. Major guidelines, including those from the American College of Gastroenterology, generally do not recommend removing the gallbladder for silent gallstones in otherwise healthy adults.

Biliary Colic

Biliary colic is the classic gallstone pain. It happens when a stone temporarily blocks the gallbladder outlet, usually after a fatty meal. The pain is felt in the upper right abdomen or the centre of the upper abdomen, can spread to the right shoulder or back, and often comes on within an hour or two of eating. It typically lasts from thirty minutes to a few hours and then settles. Nausea and vomiting are common.

Acute Cholecystitis

If a stone stays stuck and the gallbladder becomes inflamed, the result is acute cholecystitis. The pain is more constant, may last more than six hours, and is often accompanied by fever, tenderness in the upper right abdomen, and feeling generally unwell. This usually needs hospital care.

Choledocholithiasis (Stones in the Bile Duct)

A stone can pass out of the gallbladder and become lodged in the common bile duct. This blocks the flow of bile from the liver. Signs include jaundice (yellowing of the skin and eyes), dark urine, pale stools, and itching. If the trapped bile gets infected, the result is a serious condition called cholangitis, which needs urgent treatment.

Gallstone Pancreatitis

The pancreas drains into the same area as the bile duct. A gallstone that blocks this junction can cause the pancreas to inflame. Gallstone pancreatitis causes severe upper abdominal pain that often spreads to the back, vomiting, and a feeling of being very unwell. It is treated in hospital.

Causes and Risk Factors

Gallstones form when the chemistry of bile shifts so that solid material can crystallise. Several factors raise the chance of this happening.

• Female sex. Women develop gallstones more often than men, especially during the reproductive years. Oestrogen raises cholesterol in bile.
• Age. Gallstones become more common after age forty.
• Pregnancy. Hormonal changes in pregnancy slow gallbladder emptying and raise cholesterol in bile.
• Obesity and metabolic syndrome. Higher body weight, especially with insulin resistance, increases gallstone risk.
• Rapid weight loss. Crash diets and the months after weight-loss surgery are particularly high-risk periods.
• Family history. Gallstones run in families, suggesting a genetic component to bile chemistry.
• Diabetes. People with type 2 diabetes have a higher rate of gallstones.
• Diet. Diets high in refined carbohydrates and low in fibre are associated with higher risk; the link with dietary fat alone is less clear.
• Certain medications. Long-term oestrogen therapy and some cholesterol-lowering medicines can increase gallstone formation.
• Blood disorders. Conditions such as sickle cell disease and thalassaemia raise the risk of pigment stones.
• Liver disease. Cirrhosis raises the risk of pigment stones.

Gallstones are common in South Asia, and population studies suggest the rate has been rising in India alongside changes in diet and body weight. North Indian populations historically show higher rates than South Indian populations.

Signs and Symptoms to Watch For

If you already know you have gallstones, the most useful symptoms to recognise are those that suggest a complication is developing. The hallmark of gallstone pain is upper right or upper central abdominal pain, often coming on after meals, sometimes spreading to the back or right shoulder. Nausea and vomiting often go with it.

The following signs are more concerning and usually mean you need to seek medical care promptly rather than wait:

• Pain that lasts longer than a few hours or is severe
• Fever or chills along with abdominal pain
• Yellowing of the skin or the whites of the eyes (jaundice)
• Dark, tea-coloured urine and pale, clay-coloured stools
• Persistent vomiting and inability to keep fluids down
• Confusion or feeling very unwell

These can be signs of cholecystitis, a blocked bile duct, cholangitis, or pancreatitis — all of which need urgent assessment.

How Gallstones Are Diagnosed

Most gallstones are diagnosed with simple, non-invasive tests. Your doctor will combine your symptoms, examination findings, and imaging.

Abdominal Ultrasound

Ultrasound is the first test for suspected gallstones. It is painless, uses no radiation, and is highly accurate for stones in the gallbladder itself. You will be asked not to eat for several hours before the scan so that the gallbladder is full and easier to see.

Blood Tests

Blood tests check for signs of inflammation, infection, and bile duct or pancreas involvement. These typically include a full blood count, liver function tests (bilirubin, ALT, AST, alkaline phosphatase), and amylase or lipase if pancreatitis is suspected.

MRCP (Magnetic Resonance Cholangiopancreatography)

If a stone in the common bile duct is suspected but not clearly seen on ultrasound, an MRCP gives a detailed picture of the bile ducts using MRI. It does not involve radiation or contrast injection into the ducts.

Endoscopic Ultrasound (EUS)

EUS combines endoscopy with ultrasound and is very accurate for small stones in the lower bile duct. It is performed under sedation.

ERCP (Endoscopic Retrograde Cholangiopancreatography)

ERCP is both a diagnostic and treatment procedure. A flexible scope is passed through the mouth into the small intestine, and dye is injected into the bile ducts. If a stone is found, it can often be removed during the same procedure. Because ERCP carries some risk, it is generally used when treatment is likely, not for diagnosis alone.

HIDA Scan

A HIDA scan uses a small amount of radioactive tracer to study how well the gallbladder fills and empties. It is sometimes used when gallbladder disease is suspected despite a normal ultrasound, or to look at the bile flow after surgery.

CT Scan

CT is not the best test for gallstones themselves but is helpful when complications such as pancreatitis or abscess are suspected.

Treatment Options

Treatment depends on whether your gallstones are causing symptoms, what complications (if any) have developed, your overall health, and your preferences. The major options are described below.

Watchful Waiting for Silent Stones

If gallstones are found by chance and have never caused symptoms, doctors generally recommend leaving them alone. Most silent gallstones never cause problems. Major societies, including the American College of Gastroenterology, support a watchful approach in healthy adults with no symptoms.

Exceptions exist. Doctors may consider surgery even in the absence of symptoms in particular situations — for example, in people with very large stones, with a calcified (“porcelain”) gallbladder, with sickle cell disease, with certain anatomic variations, or who are about to undergo bariatric or transplant surgery. The decision is individual and made with a surgeon.

Cholecystectomy (Gallbladder Removal Surgery)

For people with symptomatic gallstones, removal of the gallbladder is the standard treatment. Once gallstones have caused pain or a complication, the chance of further problems is high if the gallbladder is left in place. Removing it is currently the most reliable way to prevent further attacks.

Cholecystectomy is one of the most common operations performed worldwide. The body manages well without a gallbladder — bile simply flows continuously from the liver into the small intestine instead of being stored.

There are two main surgical approaches.

Laparoscopic Cholecystectomy

Most people go home the same day or the day after, and return to light activity within one to two weeks. Recovery is faster, scars are smaller, and complication rates are lower than with open surgery in routine cases.

Open Cholecystectomy

In open surgery, the gallbladder is removed through a single larger cut, usually about ten to fifteen centimetres under the right rib cage. Open surgery may be needed when the gallbladder is severely inflamed or scarred, when there is significant bleeding, when the anatomy is unclear, or when a laparoscopic operation cannot be completed safely. Surgeons sometimes start with laparoscopy and convert to open surgery if needed; this is a sign of safe judgment, not a complication.

Recovery from open surgery takes longer — typically four to six weeks before resuming normal activity — and the hospital stay is usually a few days.

Robotic Cholecystectomy

In some centres, gallbladder removal is performed with robot-assisted laparoscopy. The surgical principles are the same as laparoscopic surgery; the surgeon uses a robotic console to control the instruments. For straightforward gallstone disease, robotic surgery has not been shown to give better outcomes than standard laparoscopy, but it is an option in selected cases.

ERCP for Stones in the Bile Duct

When a gallstone has moved into the common bile duct, ERCP is the usual treatment. The endoscopist passes a small cut in the muscle at the opening of the duct (sphincterotomy) and removes the stone with a balloon or basket. ERCP is often done before gallbladder removal surgery if duct stones are seen, or after surgery if a duct stone is detected later. ERCP itself does not remove the gallbladder, so most people who need ERCP for a duct stone also undergo cholecystectomy.

Non-Surgical Treatments

Non-surgical options exist but are rarely used today. They are reserved for people who cannot safely have surgery.

• Oral bile acid medications (such as ursodeoxycholic acid) can slowly dissolve some small cholesterol stones over months to years. Stones often return after the medication is stopped, and the approach is not effective for pigment stones or larger cholesterol stones.
• Extracorporeal shock-wave lithotripsy (using shock waves to break stones) is occasionally combined with oral dissolution therapy. It is not widely available for gallstones today.
• Percutaneous cholecystostomy is a tube placed through the skin into the gallbladder to drain it. It is used for very unwell patients who cannot tolerate surgery, as a temporary measure.

For most people with symptomatic gallstones who can safely have surgery, removal of the gallbladder is the option doctors most often recommend, because it treats the source of the problem rather than the individual stones.

Preparing for Gallbladder Surgery

If you are planning gallbladder removal, the preparation is usually straightforward.

• Your surgeon and anaesthetist will review your medical history, current medications, and any other health conditions.
• You may be asked to stop or adjust blood thinners, some diabetes medicines, and certain supplements before surgery.
• Routine blood tests, an ECG (in older adults), and sometimes a chest X-ray are done in the days before the operation.
• You will be asked not to eat for around six to eight hours before surgery, and not to drink clear fluids in the final two hours.
• Stop smoking as early as possible before surgery. Smoking slows healing and increases the risk of breathing problems after general anaesthesia.
• Plan for someone to take you home and stay with you for the first night after a day-case operation.

What Happens During Surgery

Cholecystectomy is performed under general anaesthesia, meaning you are fully asleep. For laparoscopic surgery, the abdomen is gently inflated with carbon dioxide gas so the surgeon can see and work around the organs. The surgeon identifies the gallbladder, separates it from the liver, ties off and divides the small artery that supplies it and the cystic duct that connects it to the bile duct, and removes the gallbladder through one of the small cuts.

An intraoperative cholangiogram — an X-ray of the bile ducts using dye — may be performed during the operation if there is any concern about stones in the duct or about the anatomy. Practice varies between surgeons and centres.

Most laparoscopic cholecystectomies take between one and two hours. You will wake up in the recovery area, often with a small dressing over each incision.

Recovery and Healing

The First Few Days

Most people feel sore for a few days after laparoscopic surgery, particularly at the incision sites and sometimes in the right shoulder — a typical and harmless effect of the carbon dioxide gas used during surgery, which resolves within a day or two. Paracetamol with or without a short course of stronger pain relief is usually enough.

You can usually eat and drink the same day, starting with light foods. Walking around your home from the first day helps prevent blood clots and stiffness.

The First Few Weeks

After laparoscopic surgery, most people return to light, sedentary activity within one to two weeks. Heavier work, lifting, and strenuous exercise are usually delayed for two to four weeks. After open surgery, recovery takes longer — typically four to six weeks before resuming normal activity, and longer before heavy lifting.

Most surgeons see you for a follow-up appointment two to six weeks after surgery to check the incisions and discuss the pathology report on the removed gallbladder.

Diet After Surgery

You do not need a special diet after gallbladder removal. Most people return to normal eating within a week or two. Because bile now flows continuously into the small intestine rather than being released in a concentrated burst with meals, some people find very fatty or very large meals harder to digest in the first few months. Bloating, loose stools, or diarrhoea after fatty foods are common and usually settle as the body adjusts. Eating smaller, more frequent meals and gradually reintroducing fatty foods can help.

Risks and Complications

Cholecystectomy is generally a safe operation, but no surgery is without risk. Discuss your individual risk profile with your surgeon. The possible complications include:

• Bleeding during or after the operation.
• Infection of the wounds or, less commonly, inside the abdomen.
• Bile leak from the area where the cystic duct was clipped. This may need drainage or, occasionally, ERCP.
• Bile duct injury. This is uncommon but serious. The common bile duct can be damaged during surgery, particularly if the anatomy is unclear or the gallbladder is severely inflamed. Repair may require further specialist surgery.
• Retained stones in the bile duct. Occasionally, a stone is detected in the duct after surgery and is usually removed with ERCP.
• Injury to nearby organs such as the bowel, blood vessels, or liver.
• Anaesthetic complications including reactions to medications, breathing or heart problems — more likely in people with significant heart or lung disease.
• Blood clots in the legs or lungs. Early walking and, in some cases, blood-thinning injections during the hospital stay reduce this risk.
• Hernia at an incision site, particularly after open surgery.

A small number of people experience ongoing digestive symptoms after surgery — abdominal pain, bloating, or diarrhoea — sometimes called postcholecystectomy syndrome. Causes vary and include irritable-bowel-type symptoms, retained stones, or other digestive conditions. If symptoms persist beyond a few months, further investigation is reasonable.

Life After Gallbladder Removal

Most people live entirely normal lives after the gallbladder is removed. Liver function is not affected. Digestion of fats continues without a gallbladder, although the bile is delivered more steadily rather than in a burst.

The most common long-term change is mild and short-lived: looser stools or urgency for a few weeks or months, particularly after fatty meals. This usually improves with time. Persistent diarrhoea is less common; if it occurs, doctors may suggest bile-acid sequestrant medications, which can be very effective.

A small number of people develop diarrhoea or other digestive issues that last longer. If you are months past surgery and still struggling, speak with your doctor — treatable causes can usually be identified.

You can resume travel, exercise, alcohol (in moderation), and normal activities. There are no long-term restrictions specific to having had a gallbladder removed.

Diet and Lifestyle

Whether you have had surgery or are managing silent or symptomatic gallstones without surgery, certain dietary and lifestyle patterns are associated with better gallbladder health in general.

• A diet with plenty of fibre, vegetables, fruits, whole grains, and healthy fats (such as those from nuts, olive oil, and oily fish) is associated with lower gallstone risk.
• Diets high in refined carbohydrates and sugary foods are associated with higher risk.
• Maintaining a stable, healthy weight is helpful. Crash dieting and very rapid weight loss are themselves risk factors for gallstone formation.
• If you are losing weight, doing so gradually (around half a kilogram to one kilogram per week) is better for the gallbladder than rapid loss.
• Regular physical activity is associated with lower gallstone risk.
• Staying well hydrated supports digestion in general.
• If you have diabetes, keeping blood sugar well controlled is helpful.

None of these measures reliably dissolves existing stones, but they support general digestive and metabolic health and may reduce the chance of new stones forming if your gallbladder is still in place.

Gallstones in Children

Gallstones in children used to be uncommon but are being diagnosed more often, partly because of greater use of ultrasound and partly because of rising rates of childhood obesity.

Causes in children include:

• Blood disorders such as sickle cell disease, hereditary spherocytosis, and thalassaemia, which cause pigment stones.
• Obesity and metabolic conditions, which can cause cholesterol stones in older children and adolescents.
• Prolonged intravenous nutrition (TPN) in babies and children who cannot eat normally.
• Certain medications, including some used in cancer care.
• Congenital problems of the bile ducts.

The symptoms of gallstones in children are similar to those in adults — upper right or central abdominal pain after meals, sometimes with nausea or vomiting — but younger children may simply seem unwell, fussy, or off their food.

Treatment principles are also similar. Silent gallstones in children are often watched, particularly in those without an underlying blood disorder. When symptoms or complications occur, laparoscopic cholecystectomy is the usual treatment. In children with blood disorders such as sickle cell disease, the threshold for surgery may be lower, because gallstone complications can be more difficult to manage during a sickle cell crisis.

Children recover from laparoscopic gallbladder removal well, often faster than adults, and grow and develop normally afterwards.

Gallstones in Pregnancy

Pregnancy increases gallstone risk, and gallstones discovered or causing symptoms during pregnancy are not unusual. Treatment is individualised. For mild biliary colic, many cases can be managed conservatively with diet and pain relief until after delivery. For acute cholecystitis or other complications, laparoscopic cholecystectomy can be performed safely during pregnancy, most commonly in the second trimester. The decision is made by a team including the obstetrician and surgeon.

Monitoring and Follow-up

If you have silent gallstones that are being watched, there is no fixed monitoring schedule. You do not generally need repeat scans unless symptoms develop. Knowing the symptoms of biliary colic and complications and seeking care if they occur is the most useful form of self-monitoring.

After cholecystectomy, follow-up is usually a single visit two to six weeks after surgery. Most people then return to routine care. The pathology report on the removed gallbladder is reviewed at this visit. In a very small number of cases, an unexpected finding (such as an incidental gallbladder cancer) is identified on pathology and requires additional follow-up.

When to Seek Urgent Care

If you have known gallstones — or have recently had gallbladder surgery — the following symptoms should prompt urgent medical attention:

• Severe upper abdominal pain that does not settle within a few hours
• Fever or chills along with abdominal pain
• Yellowing of the skin or eyes (jaundice)
• Dark urine and pale stools
• Persistent vomiting
• Confusion or feeling very unwell
• After surgery: increasing pain, fever, redness or discharge from the wounds, swelling of the abdomen, or jaundice

These can indicate cholecystitis, blocked bile duct, cholangitis, pancreatitis, or a postoperative complication, all of which need prompt assessment.

Frequently Asked Questions

Can gallstones go away on their own?

Gallstones almost never disappear on their own. Small stones occasionally pass out through the bile duct into the intestine, but the underlying tendency of the gallbladder to form stones remains. Oral medications can slowly dissolve some small cholesterol stones, but the stones often return when the medication is stopped.

If my gallstones are not causing symptoms, do I need surgery?

For most healthy adults with silent gallstones, current guidelines support not operating. The chance of silent stones causing problems each year is low. Surgery is more often considered when stones cause symptoms or complications, or in specific situations such as sickle cell disease, certain large stones, a calcified gallbladder, or before some other major surgery.

Can I live without a gallbladder?

Yes. The gallbladder stores bile but is not essential to digestion. After it is removed, bile flows continuously from the liver into the small intestine. Most people experience no long-term digestive difference.

Will my digestion change after surgery?

Some people notice that very fatty meals cause bloating or loose stools in the first weeks or months. This usually improves with time and adjusted portion sizes. A small number of people have longer-lasting diarrhoea, which is usually treatable.

How long does laparoscopic gallbladder surgery take to recover from?

Most people return to light activity within one to two weeks and to full activity within two to four weeks. Open surgery takes longer — four to six weeks for normal activity, longer for heavy work.

Will the stones come back after surgery?

Once the gallbladder is removed, gallstones cannot form in it. Rarely, stones can form in the bile ducts after surgery, particularly in people with certain underlying conditions. This is uncommon.

Are gallstones linked to cancer?

Long-standing gallstones, particularly large ones, are associated with a small increase in the risk of gallbladder cancer. Gallbladder cancer is uncommon, but it is more frequent in certain regions including North India. This is one reason that doctors may discuss surgery in selected people with large stones or a calcified gallbladder even without symptoms.

Can diet alone prevent gallstones?

Diet plays a role, but it is one factor among several. A diet rich in fibre, vegetables, and healthy fats and low in refined carbohydrates is associated with lower risk. Maintaining a stable, healthy weight and being physically active also help. None of this guarantees prevention if other risk factors (such as genetics or a blood disorder) are present.

Can I have gallbladder surgery if I have other medical conditions?

Most people, including those with controlled diabetes, heart disease, or other chronic conditions, can have laparoscopic cholecystectomy safely. Your surgeon and anaesthetist will assess your fitness for surgery and adjust the approach if needed. For people who are not fit for general anaesthesia, alternatives such as percutaneous cholecystostomy or, in rare cases, oral medications may be considered.

Is open surgery worse than laparoscopic?

Open surgery is not “worse” — sometimes it is the safer choice. The recovery is longer and the scar is larger, but in situations of severe inflammation, scarring, bleeding, or unclear anatomy, open surgery may be the right operation. Conversion from laparoscopic to open is a sign of careful judgment, not failure.

Conclusion

Gallstones are common, and most people who have them do well. For some, the stones stay silent and never need treatment. For others, gallstones cause pain or complications, and removing the gallbladder is currently the most reliable way to put the problem to rest. Whichever path applies to you, decisions about treatment are best made in conversation with a surgeon and gastroenterologist who know your individual situation — your symptoms, scan findings, other health conditions, and personal preferences.

If you are being investigated for gallstones, planning surgery, or recovering from cholecystectomy, knowing what to expect at each stage — and what symptoms should prompt urgent care — helps you make informed decisions and recover well.
