Gallstones are common but cause no symptoms in some people who have them. They cause problems such as pain, jaundice, pancreatitis, and gallbladder inflammation. Surgery is the usual treatment for gallstones .

What are the gallbladder and bile

Bile is a fluid made in the liver. Bile contains various substances including bile pigments, bile salts, cholesterol and lecithin. Bile is passed into tiny tubes called bile ducts. The bile ducts join together (like the branches of a tree) to form the main bile duct. Bile constantly drips down the bile ducts, into the main bile duct, and then into the gut.

The gallbladder lies under the liver on the right side of the upper tummy (abdomen). It is like a pouch which comes off the main bile duct and fills with bile. It is a ‘reservoir’ which stores bile.

The gallbladder squeezes (contracts) when we eat. This empties the stored bile back into the main bile duct. The bile passes along the remainder of the bile duct into the duodenum (the first part of the gut after the stomach). Bile helps to digest food, particularly fatty foods.

Knowing about gallstones

Gallstones occur when bile, which is normally fluid, forms stones. Gallstones commonly contain lumps of fatty (cholesterol-like) material that has solidified and hardened. Sometimes bile pigments or calcium deposits form gallstones. Sometimes just a few small stones are formed; sometimes a great many. Occasionally, just one large stone is formed.

About one in three women, and one in six men, form gallstones at some stage in their life. Gallstones become more common with increasing age. The risk of forming gallstones increases with pregnancy, obesity, rapid weight loss, having a close relative with gallstones, diabetes and if you take certain medicines such as the contraceptive pill. Being vegetarian and drinking a moderate amount of alcohol may reduce the risk of forming gallstones.

Hazards on having gallstones

Probable challenges

Most people with gallstones develop symptoms or problems. Symptoms are more likely to develop in smokers and women who have had babies. Symptoms include:

Biliary colic. This is a severe pain in the upper abdomen. The pain is usually worst to the right-hand side, just below the ribs. It is caused by a stone that gets stuck in the cystic duct. This is the small tube that takes bile from the gallbladder to the bile duct. The gallbladder then squeezes (contracts) hard to dislodge the stone, and this causes pain. The pain eases and goes if the gallstone is pushed out into the bile duct (and then usually out into the gut), or if it falls back into the gallbladder.

Pain from biliary colic can last just a few minutes but more commonly, lasts for several hours. A severe pain may only happen once in one’s lifetime, or it may flare up from time to time. Sometimes less severe but niggly pains occur now and then, particularly after a fatty meal when the gallbladder contracts most.

Inflammation of the gallbladder. This is called cholecystitis. This can lead to infection in the gallbladder. Symptoms usually develop quickly and include abdominal pain, high temperature (fever), and being generally unwell. You will normally be admitted to hospital and have your gallbladder removed soon if you develop this problem

Jaundice. This is an uncommon complication of gallstones. It occurs if a gallstone comes out of the gallbladder, but gets stuck in the bile duct. Bile then cannot pass into the gut, and so seeps into the bloodstream. This causes one to become yellow (jaundiced). The stone may eventually be passed into the gut. However, it is common to need an operation to remove a gallstone, which has become stuck in the bile duct. (Note: there are many other causes of jaundice apart from gallstones.)

Pancreatitis. This is an inflammation of the pancreas. The pancreas makes a fluid rich in enzymes(chemicals which digest food). The pancreatic fluid travels down the pancreatic duct. The pancreatic duct and bile duct join together just before opening into the duodenum. If a gallstone becomes stuck here it can cause pancreatitis, which is a painful and serious condition.

Other complications. These occasionally occur, such as severe infection of the bile duct, obstruction of the gut (bowel) and other uncommon gut problems.

Identification of gallstones

In many cases one’s symptoms, combined with tenderness in the upper right side of your tummy (abdomen), will alert the doctor that this is likely to be gallstones. However, tests are sometimes needed to rule out other conditions such as stomach ulcers, irritable bowel syndrome and tumours. Ultrasound scan and blood tests are the most common investigations done. Other investigations including different types of scans may sometimes be required.

Therapeutics for gallstones


Once gallstones start giving symptoms, surgery is the best treatment. However, one may be given painkillers and antibiotic medication through a drip if the gallbladder gets infected. Current eveidnce is for surgery on same admission unless there are strong contraindiaction.

Taking a medicine called ursodeoxycholicacid may sometimes dissolve small stones. This may take years of treatment, is not usually successful, and therefore not commonly used. However, it may be used to prevent gallstones developing when there is a high risk of them forming. For example, in people who lose weight rapidly following surgery for obesity.


An operation to remove the gallbladder is the usual treatment if one has symptoms caused by gallstones. Different techniques to remove the gallbladder may be recommended depending on its site, size, and other factors.

Keyhole surgery is now the most common way to remove a gallbladder. The medical term for this operation is laparoscopic cholecystectomy. It is called keyhole surgery, as only small cuts are needed in the tummy (abdomen) with small scars remaining afterwards. The operation is done with the aid of a special telescope that is pushed into the abdomen through one small cut. This allows the surgeon to see the gallbladder. Instruments pushed through another small cut are used to cut out and remove the gallbladder. Keyhole surgery is not suitable for all people.

Some people with gallstones need a traditional operation to remove the gallbladder. This is called cholecystectomy. In this operation a larger cut is needed to get at the gallbladder.

Other surgical procedures may be needed if a stone gets stuck in the bile duct.

On removal of a gallbladder

One does not need a gallbladder to digest food. Bile still flows from the liver to the gut once the gallbladder is removed. However, there is no longer any storage area for bile between meals. The flow of bile is therefore constant, without the surges of bile that occur from a gallbladder when one eats a meal.

One can eat a normal diet without any problems after one’s gallbladder is removed.
