Gallstones are small stones, usually made of cholesterol, that develop in the gallbladder. The gallbladder is a small, pouch like organ located just beneath the liver, which serves to store and concentrate bile produced by the liver to help digest fats. In many cases, these stones do not cause any symptoms and do not require treatment. However, if a gallstone becomes trapped in an opening or a duct inside the gallbladder, it can trigger sudden and intense abdominal pain. In the United Kingdom, healthcare professionals follow specific clinical pathways to identify when these stones require medical intervention or surgical removal. Understanding the nature of gallstones and how they affect the digestive system is essential for patients to recognise when to seek medical advice and how to manage the condition through lifestyle and dietary adjustments.

Gallstones are hard deposits that form in the gallbladder when there is an imbalance in the chemical makeup of bile
The formation of these stones is often linked to high levels of cholesterol or bilirubin within the gallbladder. Gallstones are thought to be caused by an imbalance in the chemical make-up of bile inside the gallbladder. When the bile contains too much cholesterol and not enough bile salts, the excess cholesterol can form into crystals that eventually grow into stones. These deposits can range in size from tiny grains of sand to the size of a large pebble. While the presence of stones is common, they only become a clinical issue when they obstruct the flow of bile, leading to inflammation or infection within the biliary system.
Identifying the symptoms of gallstones
Many people remain unaware that they have gallstones until a stone moves and causes a blockage in the bile ducts. The most common symptom of gallstones is sudden and severe pain in the abdomen that usually lasts 1 to 5 hours. This specific type of pain is known as biliary colic and is often felt in the centre of the abdomen or just under the ribs on the right hand side. The pain may be constant and is not usually relieved by passing wind or going to the toilet. In some instances, the pain can radiate to the side or the shoulder blade, and it may be accompanied by a feeling of sickness or actual vomiting.
Risk factors and preventative measures
Certain factors can increase the likelihood of developing gallstones, many of which are related to metabolic health and lifestyle choices. You are more likely to develop gallstones if you are overweight or obese as excess weight can increase the amount of cholesterol in your bile. Other factors include being female, being over the age of 40, and having a family history of the condition. Rapid weight loss can also trigger the formation of stones because it causes the liver to secrete extra cholesterol into the bile. To reduce the risk, UK health guidelines recommend maintaining a healthy weight through a balanced diet and regular physical activity, focusing on high fibre foods and healthy fats.
Clinical diagnosis and treatment pathways
If gallstones are suspected, UK clinicians utilise specific imaging tests to confirm their presence and assess any complications. The primary diagnostic tool is an ultrasound scan, which uses high-frequency sound waves to create an image of the gallbladder and the surrounding ducts. If stones are causing persistent pain or complications such as cholecystitis, the most common treatment is the surgical removal of the gallbladder. This procedure, known as a cholecystectomy, is frequently performed using keyhole surgery, allowing for a faster recovery. Because the gallbladder is not an essential organ, patients can continue to digest food normally after its removal, as the liver will simply release bile directly into the small intestine.
Conclusion
Gallstones are common deposits in the gallbladder that generally only require treatment if they cause significant pain or complications. Most cases can be managed through monitoring or surgery if an obstruction occurs in the bile ducts. Maintaining a healthy weight and a balanced diet are the most effective ways to reduce the risk of stone formation. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can I dissolve gallstones with diet?
Dietary changes can prevent new stones from forming and manage symptoms, but they cannot usually dissolve existing stones.
What happens if I don’t treat symptomatic gallstones?
Untreated gallstones that cause pain can lead to serious complications such as jaundice, gallbladder infection, or pancreatitis.
Can I live a normal life without a gallbladder?
Yes, the gallbladder is not essential for survival, and the liver will continue to produce bile to help you digest food.
Are gallstones related to kidney stones?
No, gallstones and kidney stones form in different organs and are made of entirely different substances.
Is the surgery to remove gallstones dangerous?
Cholecystectomy is a very common and generally safe procedure, though like any surgery, it carries minor risks that your surgeon will discuss.
Will I need to follow a special diet after surgery?
Most people return to a normal, healthy diet, though some may find that very fatty foods cause temporary bloating or loose stools.
How long does it take to recover from keyhole surgery?
Most patients can return to their normal activities within two to four weeks following a laparoscopic cholecystectomy.
