Gallstones Without Symptoms: Do You Still Need Surgery?
General information only: This article provides general educational information about asymptomatic gallstones. It does not replace personalised advice from your GP or surgeon. Management depends on individual circumstances. Seek urgent medical care for severe upper abdominal pain, fever, jaundice, or persistent vomiting — these may indicate a complication of gallstone disease requiring prompt assessment. |
Found on an Ultrasound — Now What?
Gallstones are one of the most common incidental findings on abdominal ultrasound in Australia. A person undergoes a scan for an unrelated reason — back pain, a check-up, a pregnancy ultrasound, or investigation of another symptom — and the report comes back noting gallstones in an otherwise normal-looking gallbladder. No pain, no nausea, no symptoms at all.
The natural next question is: do I need to do something about this? The answer is not straightforward. For most people with truly asymptomatic gallstones, current evidence supports watchful waiting. For some, individual circumstances tip the balance toward surgery. And for a minority, the discovery of gallstones — even without typical symptoms — may warrant closer attention.
Dr Devesh Kaushal is a specialist general surgeon at 4 Hyde Parade, Campbelltown, who performs laparoscopic cholecystectomy (keyhole gallbladder removal) for patients across Campbelltown, Liverpool, Camden and South Western Sydney. This article outlines how the decision about asymptomatic gallstones is approached.

What Are Gallstones and Why Do They Form?
Gallstones are solid deposits that form inside the gallbladder — a small pear-shaped organ situated beneath the liver on the right side of the upper abdomen. The gallbladder stores and concentrates bile, a digestive fluid produced by the liver that is released into the small intestine to help digest fat.
Gallstones form when the composition of bile becomes imbalanced — most commonly when bile contains too much cholesterol relative to bile salts, causing cholesterol to crystallise and aggregate into stones. Less commonly, stones form from excess bilirubin (pigment stones), which are more common in patients with haemolytic conditions or chronic liver disease.
Risk factors for gallstone formation:
Risk Factor | Notes |
Female sex | Oestrogen increases cholesterol secretion into bile and reduces bile salt secretion. Risk decreases after menopause. |
Pregnancy | Multiple pregnancies further increase risk. |
Obesity | Increases cholesterol saturation of bile. |
Rapid weight loss | Rapid fat mobilisation increases cholesterol in bile. Paradoxically, weight loss itself can precipitate stone formation. |
Age over 40 | Risk increases with age. |
Family history | Genetic factors influence bile composition and gallbladder motility. |
Diabetes and metabolic syndrome | Associated with altered bile composition and reduced gallbladder motility. |
Certain medications | Fibrates, octreotide, ceftriaxone and others can promote gallstone formation. |
Haemolytic conditions | Increased bilirubin load leads to pigment stone formation. |
The Central Question — Watchful Waiting or Surgery?
The management of truly asymptomatic gallstones is one of the more nuanced decisions in general surgical practice. Current Australian and international guidelines generally support a non-operative approach — watchful waiting — for asymptomatic gallstones in the general adult population. This recommendation is based on the relatively low annual risk of developing symptoms or complications, the risks associated with elective surgery, and evidence that the majority of patients with asymptomatic stones remain symptom-free for many years.
However, this is a general position, not a universal rule. Individual circumstances — including the patient’s age, occupation, access to emergency care, comorbidities, and specific features of the gallstones or gallbladder — can shift the balance toward surgery in selected patients. The decision is made on an individual basis after a thorough consultation.
When watchful waiting is generally appropriate:
- Truly asymptomatic gallstones — no abdominal pain, nausea, vomiting or other symptoms attributable to the gallbladder
- Small to moderate stone burden without specific high-risk features
- Patient is well-informed about the natural history and warning signs that should prompt reassessment
- Patient has reliable access to medical care should symptoms develop
- No other indication for surgery is present
When surgery may be considered even without classic symptoms:
- A single large gallstone (greater than approximately 3 cm) — associated in some studies with an increased risk of gallbladder cancer, though the overall risk remains low
- Porcelain gallbladder — calcification of the gallbladder wall. The relationship between porcelain gallbladder and cancer risk is more nuanced than previously thought and depends on the pattern of calcification; assessment by a surgeon is appropriate
- Gallbladder polyps co-existing with gallstones — polyps above a certain size threshold warrant surgical assessment
- Patient is planning significant weight loss surgery — bariatric surgery may be complicated by symptomatic gallstones in the postoperative period, and prophylactic cholecystectomy is sometimes discussed in this context
- Patient is about to travel to a remote area or country with limited access to emergency surgical care for an extended period
- Patient works in an occupation where an acute gallstone episode could create a safety risk — for example, pilots, divers, or those in remote work settings
- Haemolytic anaemia — such as sickle cell disease — where the risk of complications from gallstones is higher than in the general population
- Patient preference — after full discussion of the risks, benefits and alternatives — for elective removal rather than living with the uncertainty of watchful waiting
Individual assessment matters: These are general considerations, not fixed rules. The decision about whether to proceed with or defer surgery for asymptomatic gallstones should be made after a thorough individual consultation with a surgeon who can review the ultrasound findings, consider relevant personal circumstances, and discuss the full range of options. |
What Are the Risks of Leaving Gallstones Alone?
Choosing watchful waiting is a reasonable and clinically supported option for most people with asymptomatic gallstones. It is, however, not without uncertainty. The following outlines what is known about the natural history of asymptomatic gallstones:
- Annual risk of developing symptoms: Approximately 1 to 2% per year develop biliary colic or other symptoms. Over 5 years, the cumulative risk of symptoms is in the range of 10 to 25%, though studies vary considerably.
- Risk of serious complications as first presentation: A small proportion of patients with previously asymptomatic gallstones present for the first time with a complication — such as acute cholecystitis, cholangitis, pancreatitis or bile duct obstruction — rather than a warning episode of biliary colic. Severe acute pancreatitis related to gallstones can be life-threatening.
- Elective vs emergency surgery: Surgery performed electively — planned, at a time of the patient’s choosing, when they are well — is consistently associated with lower complication rates than emergency surgery performed during an acute attack. This is a relevant consideration for patients with significant medical comorbidities, in whom emergency surgery would carry substantially higher risk.
- Stones generally do not resolve: Gallstones do not dissolve or disappear spontaneously in the vast majority of cases. Oral bile acid therapy (ursodeoxycholic acid) can dissolve small cholesterol stones in selected patients with a functioning gallbladder, but recurrence rates after stopping treatment are high and this is rarely used in current Australian practice.
No urgent decision required: For most patients with asymptomatic gallstones, there is no urgency to make an immediate decision about surgery. A surgical consultation provides an opportunity to discuss the options, understand the individual risk profile, and plan appropriately — without pressure to proceed.
Symptoms to Watch For — When to Seek Assessment
Patients who choose watchful waiting should be aware of the symptoms that indicate gallstone disease has become active. Recognising these early and seeking timely medical review reduces the risk of complications developing.
Symptoms of biliary colic — see your GP:
- Episodic pain in the right upper abdomen or epigastrium — typically occurring after fatty meals
- Pain that may radiate to the right shoulder or shoulder blade
- Nausea associated with the pain episode
- Episodes lasting 30 minutes to several hours, then settling
- Repeated episodes — each episode of biliary colic significantly increases the risk of the next episode and of complications
🔴 Seek urgent care (emergency department or call 000) for:
• Severe, constant upper abdominal pain lasting more than 6 hours — may indicate acute cholecystitis
• Pain with fever and chills — suggests infection (cholecystitis or cholangitis)
• Yellowing of the skin or eyes (jaundice) — indicates bile duct obstruction
• Severe pain radiating to the back with nausea and vomiting — may indicate gallstone pancreatitis
• Inability to keep fluids down due to vomiting
Complications of gallstone disease — particularly cholangitis (bile duct infection) and severe pancreatitis — can be life-threatening and require urgent hospital assessment.
About Laparoscopic Cholecystectomy — If Surgery Is Recommended
If you and Dr Kaushal determine that surgery is the appropriate course of action, the standard operation is laparoscopic cholecystectomy — keyhole removal of the gallbladder. This is one of the most commonly performed operations in Australia.
Aspect
Details
Procedure
Laparoscopic (keyhole) removal of the gallbladder under general anaesthesia through four small incisions in the abdomen.
Duration
Typically 45 to 90 minutes for an elective case.
Hospital stay
Most patients are discharged the same day or the following morning.
Recovery
Return to desk work in 1 to 2 weeks. Full activity including manual work by 4 to 6 weeks in most cases.
Elective advantage
Elective surgery in a patient who is well is consistently associated with lower complication rates than emergency surgery during an acute episode.
Life without a gallbladder
The body functions normally without a gallbladder. Bile flows directly from the liver to the small intestine. Most people have no long-term dietary restrictions. A small proportion notice looser stools, particularly after fatty meals.
Frequently Asked Questions
-
My gallstones have been there for years and never caused trouble — should I still be concerned?
The longer gallstones remain asymptomatic, the less likely they are to cause problems — some studies suggest the risk of developing symptoms decreases the longer stones have been present without causing symptoms. However, the risk never reaches zero. The key is to remain aware of the warning symptoms that indicate the stones have become active, and to seek prompt medical review if those symptoms occur. A surgical consultation is a reasonable step to understand your individual risk profile and decide together whether watchful waiting or elective surgery is the more appropriate approach.
Can diet or medication dissolve gallstones?
Dietary changes cannot dissolve formed gallstones, though they may reduce the frequency of symptoms by limiting fatty food intake that triggers gallbladder contraction. Oral bile acid therapy with ursodeoxycholic acid can slowly dissolve small cholesterol gallstones in patients with a functioning gallbladder, but the treatment takes many months, is not effective for large stones or pigment stones, and recurrence after stopping is common. It is rarely used in current clinical practice in Australia. There is no evidence that herbal products, supplements or other non-medical approaches dissolve gallstones.
I am planning weight loss surgery — do my gallstones need to be removed first?
This is an important consideration. Rapid weight loss — which occurs after bariatric surgery — is one of the recognised factors that can trigger gallstone symptoms or accelerate gallstone formation. Patients with known gallstones who are planning bariatric surgery should discuss this with their bariatric surgeon. In some cases, concurrent cholecystectomy at the time of bariatric surgery may be considered. In others, the stones are monitored and surgery planned only if they become symptomatic. The appropriate approach depends on the type of bariatric procedure, the current state of the gallstones, and individual clinical factors.
I have been told I have a large gallstone — is that more dangerous?
The relationship between gallstone size and clinical outcomes is complex. Large stones — particularly those greater than approximately 3 cm in diameter — have been associated in some epidemiological studies with a slightly increased risk of gallbladder cancer compared with smaller stones or no stones. However, the absolute risk of gallbladder cancer remains low, and this alone does not automatically mean surgery is required. A surgical consultation is appropriate to discuss the significance of a large stone in the context of your overall clinical picture.
What happens if I need emergency gallbladder surgery?
Emergency cholecystectomy — performed during an acute episode of cholecystitis, cholangitis or pancreatitis — is technically more challenging than elective surgery because of inflammation, tissue oedema and altered anatomy. It is associated with higher rates of bile duct injury, conversion to open surgery, wound infection, prolonged hospital stay and other complications compared with planned elective surgery. For patients with significant medical comorbidities, emergency surgery carries a substantially higher risk than the same operation performed electively when the patient is well. This is one of the arguments that surgeons consider when discussing elective cholecystectomy with patients who have asymptomatic or mildly symptomatic gallstones.

Gastroscopy — upper endoscopy — is the investigation commonly used in the assessment of suspected bile reflux. It is important to note that endoscopic appearances alone are not diagnostic — the overall clinical picture, including symptoms, histological findings, and where appropriate, additional investigations, should be considered when making a diagnosis. In clinical practice, the endoscopic findings of bile reflux are sometimes described in the literature — findings that may suggest bile reflux when interpreted in the appropriate clinical context:
Endoscopic Finding | What It Means Clinically |
Greenish-yellow bile-stained fluid pooled in the stomach | A small amount of bile in the fasting stomach may be seen in otherwise normal individuals and does not in isolation confirm pathological bile reflux. Significant pooling, in the context of symptoms and other findings, is more clinically relevant. |
Erythematous (reddened) gastric mucosa | Bile acids are capable of contributing to mucosal irritation and inflammation with prolonged exposure. The reddened lining may reflect bile-induced chemical gastropathy, though these appearances are not specific to bile reflux and can be seen in other forms of chemical gastritis. |
Granular or nodular mucosal pattern | A granular or nodular mucosal surface in the stomach, particularly in the antrum, may be seen in bile reflux gastritis but is not specific to this condition — similar appearances can occur in other forms of chemical gastropathy and should always be interpreted in the context of symptoms and histological findings. |
Bile in the oesophagus | When bile refluxes high enough to reach the oesophagus, the oesophageal lining is exposed to a combination of acid and bile — a more damaging combination than either alone. |
