gallstones introduction

The gallbladder, a tiny pear-shaped organ underneath the liver, forms gallstones. The gallbladder stores liver-produced bile and releases it into the small intestine to help digest lipids.

Cholesterol or bilirubin—a pigment released when red blood cells break down—make up gallstones. They range from sand grains to golf balls. Gallstones may be single or clustered.

Several causes induce gallstones, but their aetiology is unknown. These are:

Gallstones may arise from excess cholesterol in bile.

Concentrated bile: Inadequate fluid intake or excessive bile water absorption might cause gallstones.

Decreased gallbladder motility may cause bile to stagnate and produce gallstones.

Obesity: High cholesterol and gallbladder motility enhance gallstone risk.

Rapid weight loss: Crash diets and bariatric surgery may alter bile components and cause gallstones.

Hormonal factors: Pregnancy and some contraception might increase gallstone risk.

Gallstones are commonly found during medical imaging testing for unrelated illnesses in people who have no symptoms. Biliary colic occurs when gallstones obstruct the bile ducts, causing severe abdominal discomfort. Nausea, vomiting, jaundice, and clay-colored faeces may occur.

Symptoms and consequences determine gallstone treatment. Asymptomatic gallstones may not need treatment. If symptoms emerge or problems like gallbladder inflammation or bile duct blockage occur, treatment options include medication, minimally invasive treatments to remove or dissolve stones, or cholecystectomy.

Gallstones may cause major consequences if ignored, therefore it’s important to see a doctor.


Gallstones develop for unknown reasons. Several variables influence their growth. Gallstone causes:

Excess cholesterol in bile: Cholesterol stones are the most prevalent gallstones. Cholesterol-rich bile may form crystals that become gallstones.

Concentrated bile: Liver-produced bile aids fat digestion. Gallstones may occur if bile becomes excessively concentrated owing to insufficient fluid intake or excessive bile water absorption.

Reduced gallbladder emptying: The gallbladder stores and releases bile for digestion. When the gallbladder doesn’t empty or contract adequately, bile may stagnate and create gallstones.

Obesity: Obesity increases gallstone risk. Obesity increases bile cholesterol and decreases gallbladder motility, which encourage gallstone development.

Rapid weight loss: Crash diets and bariatric surgery may disturb bile component balance and increase gallstone risk.

Hormonal factors: Pregnancy and hormonal contraception may increase gallstone risk. Oestrogen increases bile cholesterol and decreases gallbladder motility.

Gallstones are more frequent in elderly people, particularly those over 40. Hormonal considerations make women more prone to gallstones than males.

Family history: Gallstones are more likely in families. Gallstones may be genetic.

It’s important to note that although these characteristics contribute to gallstones, not everyone with them will have them, and those without them may still get them. Some people with gallstones have no symptoms, while others suffer difficulties. If you think you have gallstones or are at risk, see a doctor.


Gallstones may or may not produce symptoms. Gallstone size, position, and obstruction or inflammation affect symptoms. Gallstone symptoms include:

Gallstones most often cause biliary colic. Biliary colic is severe, episodic abdominal discomfort. The discomfort is abrupt, lasts a few minutes to many hours, and may spread to the back or right shoulder. After a fatty meal or at night, biliary colic ensues.

Gallstones may produce nausea and vomiting, particularly during or following biliary colic.

Jaundice: Gallstones clog bile ducts, causing skin and eye yellowing. Dark urine and pale faeces may also occur.

Gallstones may cause abdominal bloating and pain. Some people have moderate stomach pain.

Gallstones may cause indigestion, gas and belching.

Changes in bowel movements: Gallstone-related blockage or inflammation may disrupt bile flow into the gut. Bile pigments reaching the intestines diminish, making stools clay-colored or pale.

These symptoms might be caused by other illnesses than gallstones. If you have any of these symptoms, see a doctor for an appropriate diagnosis. Gallstones may cause cholecystitis, infection, pancreatitis, or choledocholithiasis, which need immediate medical intervention.


Medical history, physical exam, and diagnostic testing are used to identify gallstones. Common gallstone diagnosis techniques include:

Imaging tests: Gallstone detection and gallbladder visualisation need imaging. Tests may include:

a. Ultrasound is the most popular non-invasive gallstone imaging test. Gallstones may be detected, measured, and located using ultrasound.

b. CT scan: A CT scan may provide comprehensive abdominal cross-sectional images. It shows gallstones and problems.

c. MRI: Radio waves and magnetic fields provide detailed pictures of the gallbladder and bile ducts. Inconclusive ultrasound or CT scan findings may prompt its usage.

Blood testing: Blood tests may reveal inflammation and infection in the liver. Liver enzymes and bilirubin may suggest gallstone problems.

Cholescintigraphy (HIDA scan): This nuclear medicine scan injects a radioactive material into the circulation, which the liver absorbs and excretes as bile. Radioactive material migration may indicate gallstones and gallbladder function.

Endoscopic retrograde cholangiopancreatography (ERCP): When gallstones clog bile ducts, ERCP may be done. A camera-equipped flexible tube is inserted into the mouth, oesophagus, and small intestine. Contrast dye is injected to detect gallstones and problems with X-rays.

Other diagnostic procedures: MRCP or PTC may be used to assess the bile ducts and discover gallstones.

Consult a doctor if you think you have gallstones. They will assess your symptoms, run diagnostic testing, and offer an accurate diagnosis to guide therapy.


Gallstones are either cholesterol or pigment stones. Risk factors vary by kind.

80% of gallstones are cholesterol stones. Liver-produced cholesterol makes up these stones. Cholesterol stones are mostly caused by:

A. Excess cholesterol: Too much cholesterol and not enough bile salts may produce crystals that develop into stones.

b. Obesity: Obesity increases cholesterol gallstone risk. Obesity increases cholesterol production and gallbladder function.

d. Crash diets and bariatric surgery may cause cholesterol stones. Rapid weight loss may affect metabolism and bile equilibrium.

Pigment stones, made by bilirubin from red blood cell breakdown, are rare. Pigment stones have two subtypes:

A. Black pigment stones are tiny, firm, and black. They contain a lot of bilirubin and are linked to liver cirrhosis, hemolytic anaemia, and some infections.

b. Brown Pigment Stones: Softer and greasier than black pigment stones. Recurrent biliary infections and parasites induce bile stasis and bacterial infection in the bile ducts.

Cholesterol and pigment stones are treated similarly. Symptoms, stone size and quantity, and consequences determine therapy. Gallstones may be treated with medicine, non-surgical methods to remove or dissolve the stones, or cholecystectomy.

Imaging and lab testing help doctors identify gallstones.


Gallstone therapy varies on symptoms, size, quantity, and risk of complications. Gallstone treatments:

Watchful waiting: Small, asymptomatic gallstones may be left alone. Cholesterol stones are less prone to cause difficulties. Monitoring and lifestyle changes may help control symptoms and prevent problems.

Medication: Most medications dissolve cholesterol stones or treat gallstone symptoms. Ursodeoxycholic acid (UDCA) is most often used. Over months to years, UDCA dissolves smaller cholesterol stones. It is not for everyone, and the stones may return after stopping the drug.

Non-surgical methods:

a. Extracorporeal Shockwave Lithotripsy (ESWL): High-frequency sound waves shatter gallstones into fragments that may flow via the bile ducts. This treatment works for tiny cholesterol stones.

b. ERCP removes gallstones from bile ducts. A camera-equipped flexible tube is inserted into the mouth, oesophagus, and small intestine. Stones may be removed or broken down using certain tools.

Cholecystectomy is the most frequent and effective gallstone therapy. The gallbladder is surgically removed to prevent gallstones. Laparoscopic cholecystectomy uses smaller incisions and less recovery time than open surgery.

The patient’s health, gallstone size and quantity, symptoms, and risk of consequences determine the therapy. A doctor may assess the condition and prescribe therapy.

After gallbladder surgery, bile passes straight from the liver to the small intestine, affecting digestion. Most people may live a healthy life without a gallbladder, although others may have diarrhoea or bloating. Dietary changes may help.


Lifestyle changes may minimise the risk of gallstones or their recurrence following therapy. Preventive measures:

Obesity increases gallstone risk. Thus, eating well and exercising may lower the risk.

Balanced diet: Eat fruits, vegetables, whole grains, lean meats, and healthy fats. High-fat, cholesterol-rich diets may cause gallstones.

Weight loss: Lose 1-2 pounds each week if required. Rapid weight reduction increases gallstone risk.

Maintain a healthy weight and digestion through walking, jogging, or other exercise.

Maintain a nutritious diet: Eat regularly, avoid crash diets, and limit processed carbohydrates and saturated fats.

Stay hydrated: Drink enough water to keep bile flowing and prevent it from concentrating.

Limit alcohol: Excessive drinking might cause gallstones. Moderate or avoid alcohol.

Hormone replacement treatment and cholesterol-lowering medicines may raise gallstone risk. If given such drugs, discuss risks with your doctor.

Manage underlying conditions: Diabetes and liver disorders enhance gallstone risk. Manage these conditions under medical supervision.

Avoid fast weight fluctuations: Gaining and losing weight regularly increases gallstone risk. Maintain your weight.

These steps may lower gallstone risk, but they may not prevent them. For personalised gallstone advice, visit a healthcare expert.


Gallstones, especially cholesterol stones, are treated with medications. Common gallstone medicines include:

Ursodeoxycholic Acid (UDCA) dissolves gallbladder cholesterol stones. It reduces liver cholesterol and increases bile acids. This dissolves cholesterol stones over months or years. UDCA works well for tiny stones and may be advised for non-surgery patients.

Chenodeoxycholic Acid (CDCA) dissolves cholesterol stones too. It reduces cholesterol synthesis and breaks cholesterol stones like UDCA. CDCA is less popular than UDCA owing to side effects and patient characteristics.

Medication treatment for gallstones is usually reserved for those who cannot undergo surgery or prefer non-surgical alternatives. Medication may not completely dissolve gallstones. After discontinuing treatment, recurrence is possible.

The size and quantity of stones, symptoms, and patient preferences determine medication and treatment length. A doctor evaluates the issue and recommends medicine for gallstones.

Medication treatment is not appropriate for pigment gallstones. Bilirubin pigment stones cannot be dissolved with medicine. Cholecystectomy may be advised.

Risk factors

Gallstones risk factors include many. Lifestyle adjustments may address certain risk factors, but not all. Common gallstone risk factors:

Gallstones are more common in women. Oestrogen may raise bile cholesterol and decrease gallbladder motility.

Age increases gallstone risk. Over-40s have more gallstones.

Obesity increases gallstone risk. Obesity raises cholesterol, slows gallbladder emptying, and changes bile composition.

Crash diets and bariatric surgery may raise gallstone risk. The liver releases more cholesterol into the bile when fat is metabolised quickly, raising cholesterol stone risk.

Family history: Gallstones are more likely if a parent or sibling has them. Gallstones may be genetic.

Gallstones are more common among Native Americans, Hispanics, Scandinavians, and Mexicans.

Saturated fats, cholesterol, and refined carbs raise gallstone risk. Fibre, fruits, vegetables, and healthy fats may lower risk.

Sedentary lifestyle: Gallstones are linked to inactivity. Exercise aids digestion and weight management.

Liver illness, Crohn’s disease, and diabetes may raise gallstone risk.

Hormone replacement treatment and fibrates may increase gallstone risk.

Having risk factors doesn’t guarantee gallstones. Some people without risk factors develop gallstones. Consult a doctor for personalised advice and monitoring if you have gallstone issues or risk factors.


Q: Do gallstones dissolve by themselves?
A: Gallstones seldom disappear by themselves. Gallstones usually stay until addressed. Small gallstones may be asymptomatic and not need treatment.

Can diet prevent gallstones?
A: A nutritious diet helps lower gallstone risk, but it cannot prevent them. Eat lots of fruits, veggies, healthy grains, and lean meats. Avoid crash diets and high-fat, cholesterol-rich meals to reduce gallstone risk.

Q: Can gallstone patients consume fat?
A: Gallstone sufferers should restrict or avoid greasy meals. High-fat diets cause gallbladder spasms and pain. However, a healthcare practitioner or certified dietitian may tailor nutritional advice to your situation.

Can medicine remove gallstones completely?
A: Ursodeoxycholic acid (UDCA) dissolves cholesterol stones over months to years. However, total disintegration may not be accomplished, and recurrence may occur after treatment discontinuation. Medication treatment is usually recommended for those who are not surgical candidates or prefer non-surgical choices.

Gallstone surgery—is it the only option?
A: Gallstone surgery—cholecystectomy—is the most frequent and effective therapy. Depending on the patient’s health and preferences, medicines or non-surgical methods may be chosen.

Gallstone complications?
A: Gallstones may cause cholecystitis, choledocholithiasis, gallbladder infection, and pancreatitis. Severe stomach discomfort, prolonged nausea or vomiting, or yellowing skin or eyes may suggest gallstone problems.

Can I survive without a gallbladder?
A: Gallbladder-free living is conceivable. After cholecystectomy, bile travels from the liver to the small intestine. Some people may have loose stools or more frequent bowel movements without a gallbladder, but most may live a healthy life without one. These alterations may be managed by eating smaller, more frequent meals and lowering fat consumption.

Myth vs fact

Myth: Fat causes gallstones.
Fact: High-fat diets may induce gallstones, but not exclusively. Genetics, hormones, and bile composition cause gallstones.

Myth: Only elderly people acquire gallstones.
Fact: Children and young adults may develop gallstones, even though the risk rises with age.

Myth: Rapid weight loss eliminates gallstones.
Fact: Crash diets and bariatric surgery increase gallstone risk. Sudden weight reduction may cause gallstones by disrupting bile components.

Myth: Drugs cure gallstones.
UDCA may dissolve cholesterol gallstones over time. However, total disintegration may not be accomplished, and recurrence may occur after treatment discontinuation.

Myth: All gallstones induce symptoms.
Gallstones don’t always hurt. Asymptomatic gallstone sufferers are common. Imaging for various reasons frequently finds gallstones.

Myth: Gallstones need surgery.
Fact: Cholecystectomy, the most frequent gallstone surgery, is not the only choice. Based on the patient’s health and preferences, medications or non-surgical techniques like extracorporeal shockwave lithotripsy (ESWL) or endoscopic retrograde cholangiopancreatography (ERCP) may be explored.

Myth: Avoiding all fats prevents gallstones.
Fact: A high-fat diet may cause gallstones, but restricting fats is unnecessary. Healthy fats like avocados, almonds, and olive oil are essential. A nutritious diet with modest fats is advised.

Myth: Gallstones never return.
Fact: Gallstones may develop again in the bile ducts after gallbladder surgery. Symptomatic gallstones are rarer without the gallbladder.

Gallstones: Cholesterol or bilirubin-based gallbladder deposits. They may induce stomach pain and discomfort.

Gallstones made by cholesterol are the most prevalent. Cholesterol crystallises in bile imbalances.

Pigment stones: Bilirubin-rich gallstones. These darker stones are smaller.

Bile: Liver-produced gallbladder fluid. It helps digest fat. Bile comprises cholesterol, bile salts, bilirubin, and water.

Bile ducts convey bile from the liver to the gallbladder and small intestine. The gallbladder is connected to the common bile duct through the cystic duct.

Cholecystectomy: Gallbladder surgery. It’s the most usual gallstone therapy when symptoms arise.

Cholecystitis: Gallstone-induced gallbladder inflammation. Fever, stomach discomfort, and other symptoms may ensue.

Gallstone-induced biliary colic: severe pain. Biliary colic causes severe stomach cramps after eating.

Choledocholithiasis: Common bile duct gallstones. Bile flow obstruction may induce jaundice, stomach discomfort, and pancreatitis.

ERCP (Endoscopic Retrograde Cholangiopancreatography): A technique that uses endoscopy and X-rays to identify and treat bile duct and pancreatic problems. It removes bile duct gallstones.
