Gallstones are small, hard deposits that form in the gallbladder, a small organ located under the liver. They can vary in size and number, with two main types occurring: cholesterol stones and pigment stones.
In many cases, gallstones do not cause any symptoms and do not require treatment. However, if a gallstone blocks the flow of bile through the bile ducts, it can lead to inflammation or infection of the gallbladder or other serious conditions affecting the liver and pancreas.
The primary cause of gallstone formation is an imbalance in the chemical composition of bile, a digestive fluid produced by the liver. This imbalance can lead to the crystallisation of bile components, forming gallstones.
For cholesterol stones, the imbalance involves an excess of cholesterol in bile, while for pigment stones, it is an excess of bilirubin.
This imbalance can lead to the crystallisation of bile components, forming gallstones.
Asymptomatic Gallstones
Symptomatic Gallstones
When symptoms do occur, they often include:
Sudden and intense pain in the upper right abdomen: Also known as biliary colic, this is one of the most common symptoms of gallstones. The pain can last from a few minutes to several hours, radiating to the back or right shoulder blade.
Nausea or vomiting: These symptoms often accompany the pain from biliary colic, indicative of digestive distress when a gallstone causes an obstruction.
Indigestion: This often presents as discomfort or a feeling of fullness after eating, particularly following meals high in fat.

Ursodeoxycholic acid may be prescribed to dissolve small cholesterol gallstones, working by reducing cholesterol production and synthesis.
However, this option can take several months to years to work, with stones potentially recurring. It is crucial to consult a gallstones doctor to determine suitability, as side effects may occur.
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a procedure using an endoscope to access, break up, and remove gallstones lodged in the bile duct. While effective, potential risks include allergic reactions and inflammation to the pancreas.
Laparoscopic Cholecystectomy: This is a surgical procedure where several small incisions are made in the abdomen to remove the gallbladder using a laparoscope and surgical instruments. The gallstones surgeon performs the operation while viewing a video monitor that displays the internal view of the abdomen. The procedure is minimally invasive, involving less postoperative pain and a shorter recovery time.
Open Cholecystectomy: This is a traditional surgery in which a larger incision is made in the abdomen to access and remove the gallbladder. It may be used in cases where the gallbladder is severely diseased, making removal more challenging, or if complications arise during a laparoscopic procedure.
In some cases, gallstones can lead to several complications:
Cholecystitis: This involves inflammation of the gallbladder, typically occurring when a gallstone blocks the cystic duct, leading to pain and potential infection. For acute cases, immediate medical attention by a gallbladder inflammation specialist is required.
Pancreatitis: If a gallstone blocks the pancreatic duct, the pancreas may get inflamed. Patients often experience severe abdominal pain and require urgent medical attention from a pancreatitis doctor.
Cholangitis: This is a serious infection of the bile ducts, usually resulting from gallstone obstruction, and can cause fever, jaundice, and abdominal discomfort.
Gallbladder Cancer: Although rare, a history of gallstones, particularly large ones, is considered a risk factor for this serious complication.

Dr Thng Yongxian is a dual fellowship-trained Hepatopancreatobiliary & General Surgeon who has performed over 6000 surgical procedures.
He pursued his subspecialty training in Hepatopancreatobiliary surgery first in the Department of Hepatopancreatobiliary Surgery, Singapore General Hospital. Following this, he completed a clinical fellowship in Minimally Invasive Hepatopancreatobiliary Surgery at Seoul National University Hospital in Bundang, South Korea.
Dr Thng set up and pioneered the Minimally Invasive surgery programme for his hospital in complex liver and pancreas cases. His surgeries were featured on live national television, while his surgical videos have been presented at international surgical conferences. He also pioneered the use of capsule colonoscopy for colorectal screening.
Dr Thng has served on various committees at hospital, cluster and ministry level. For example, he was a member of the Ministry of Health (MOH) Laparoscopic Cholecystectomy Clinician workgroup for value-driven care (VDC).
Preventing the formation of gallstones may not always be possible, but some measures can reduce the risk.
Healthy Weight Management: As obesity and rapid weight loss are significant risk factors in the development of gallstones, maintaining a healthy weight can help prevent their formation.
Balanced Diet: Maintain a high-fibre and healthy fats diet while limiting intake of refined carbohydrates and unhealthy fats.
Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic activity, such as brisk walking, each week. Alternatively, engage in 75 minutes of vigorous-intensity activity, like running.
