Gallstones: Why They’re Being Diagnosed More Often and What You Need to Know

Have you ever experienced a sudden pain in the upper part of your tummy after a meal? Perhaps it felt like a sharp ache beneath your right ribs, or the discomfort travelled towards your back and shoulder.

While digestive discomfort can have many causes, one possibility is gallstones.

Gallstones are a common condition affecting the gallbladder. They can develop quietly without causing any symptoms, or they may lead to episodes of significant abdominal pain that interfere with everyday life.

In recent years, gallstones have received more attention, with clinicians reporting that they are seeing more patients, including younger adults. Changes in lifestyle, weight patterns and increased use of medical imaging may all contribute to this trend. However, research does not yet establish a consistent rise in gallstone prevalence across Australia.

Understanding gallstones, their risk factors and the symptoms to look out for can help you make informed decisions about your digestive health.

What Are Gallstones?

The gallbladder is a small, pear-shaped organ located beneath your liver on the right side of your abdomen.

Its main role is to store bile, a digestive fluid produced by the liver. Bile helps your body break down fats from the food you eat.

Gallstones form when substances within bile, such as cholesterol or bile pigments, harden into small stone-like deposits.

These stones can vary in size. Some are as small as grains of sand, while others may grow much larger. A person may develop a single gallstone or several.

Not everyone with gallstones experiences symptoms. In many cases, they are discovered incidentally during an ultrasound or another medical investigation. (Healthdirect Australia)

Are Gallstones Becoming More Common?

Gallstones are already a common digestive health condition. Some Australian clinicians have reported seeing them more frequently, including in younger patients.

Several factors may contribute to the pattern:

• Changes in dietary habits

• Increasing rates of overweight and obesity

• Metabolic conditions such as diabetes

• Rapid weight loss associated with certain diets or weight-loss treatments

• An ageing population

• Greater use of ultrasound and other imaging tests, leading to more incidental diagnoses

It is important to distinguish between a condition becoming more common and a condition being diagnosed more often.

A recent international systematic review involving more than 32 million participants found that the overall prevalence of gallstones had remained relatively stable over the previous two decades, although incidence may be increasing. Australian-specific trends are not definitively established. (PubMed – Global Epidemiology of Gallstones)

Regardless of whether prevalence is rising nationally, gallstones remain an important health issue because they can cause pain and, in some cases, serious complications.

What Causes Gallstones?

Gallstones do not develop for one single reason. They can form when the balance of substances in bile changes or when the gallbladder does not empty as effectively as it should.

Some factors can increase the likelihood of developing gallstones.

Age and Gender

Gallstones become more common with age and are more frequently diagnosed in women than men.

Hormonal factors can influence how cholesterol is handled in the body, which may contribute to the increased risk in women.

Weight and Metabolic Health

Living with overweight or obesity can increase the risk of cholesterol gallstones.

Conditions such as diabetes and other metabolic disorders may also be associated with a higher risk.

Rapid Weight Loss

Losing weight quickly can increase the likelihood of gallstone formation.

This may occur following crash diets, rapid weight-loss programmes or certain bariatric procedures.

Gradual, sustainable weight management is generally a better approach than extreme dieting.

Pregnancy

Hormonal changes during pregnancy can affect the gallbladder and bile composition.

Some women may develop gallstones during pregnancy, although not all will experience symptoms or require treatment.

Family History

If close family members have had gallstones, your risk may be higher.

Dietary Habits

Dietary patterns may play a role in gallstone risk. Diets high in saturated fat and low in fibre, along with irregular eating patterns, may contribute to poor metabolic health.

However, gallstones are not simply caused by eating one particular food. Their development is influenced by several factors, including genetics, hormones and overall health. (Healthdirect Australia)

What Are the Symptoms of Gallstones?

Many people have gallstones without ever knowing it.

When symptoms do occur, they often happen when a stone temporarily blocks the flow of bile from the gallbladder.

This can cause a type of pain known as biliary colic.

Common symptoms include:

• Sudden pain in the upper right abdomen

• Pain beneath the ribs or in the middle of the upper tummy

• Pain that spreads towards the back or right shoulder

• Nausea or vomiting

• Discomfort following a meal, particularly a fatty meal

• Episodes of pain lasting from minutes to several hours

The pain may come and go. Some people describe it as a deep ache, while others experience intense, sharp discomfort.

It is worth noting that not every episode of upper abdominal pain is caused by gallstones. Conditions such as reflux, gastritis, ulcers and other digestive problems can cause similar symptoms.

If you experience repeated episodes of abdominal pain, speak with your GP rather than assuming the cause.

When Can Gallstones Become Serious?

Although many gallstones remain harmless, complications can occur if a stone blocks a bile duct.

These complications may include:

Gallbladder Inflammation

A stone may block the gallbladder's outlet, causing inflammation known as cholecystitis.

Symptoms may include persistent abdominal pain, fever, nausea and vomiting.

This condition requires prompt medical assessment.

Jaundice

If a gallstone blocks a bile duct, bile may build up in the bloodstream.

This can cause yellowing of the skin or the whites of the eyes. You may also notice dark urine, pale stools or itching.

Pancreatitis

Gallstones can sometimes block the drainage pathway of the pancreas, leading to inflammation called gallstone pancreatitis.

This may cause severe upper abdominal pain that spreads to the back, often with nausea and vomiting.

Pancreatitis is a serious condition that requires urgent hospital care. (NSW Health Emergency Care Institute)

Seek urgent medical attention if you experience severe or persistent abdominal pain, fever, repeated vomiting, yellowing of your skin or eyes, or pain that prevents you from eating or drinking normally.

How Are Gallstones Diagnosed?

If your GP suspects gallstones, they may ask about your symptoms, medical history and any patterns you have noticed with meals.

An abdominal ultrasound is commonly used to identify gallstones. It is a non-invasive test that uses sound waves to produce images of the gallbladder and surrounding structures.

Your doctor may also recommend blood tests to assess liver function and look for signs of inflammation or complications.

Depending on your symptoms and test results, further investigations may be needed.

An important point is that finding gallstones on a scan does not automatically mean they are responsible for your symptoms. Your GP will consider the overall clinical picture. (Healthdirect Australia)

How Are Gallstones Treated?

Treatment depends on whether gallstones are causing symptoms or complications.

Gallstones Without Symptoms

If gallstones are discovered accidentally and are not causing any problems, treatment is often not required.

Your doctor may recommend monitoring and discussing what symptoms to look out for.

Dietary Changes

If you experience symptoms, certain dietary adjustments may help reduce episodes of discomfort.

Your GP may suggest:

• Limiting foods that trigger symptoms

• Reducing very fatty meals

• Eating a balanced diet with plenty of vegetables and fibre

• Maintaining regular meals

• Avoiding crash diets

• Aiming for gradual weight loss if appropriate

Dietary changes may help manage symptoms, but they do not reliably dissolve existing gallstones.

Gallbladder Surgery

If gallstones repeatedly cause pain or lead to complications, surgery may be recommended.

The most common procedure is a cholecystectomy, which involves removing the gallbladder.

Many operations are performed using keyhole surgery, also known as laparoscopic surgery. This generally involves smaller incisions and a shorter recovery period compared with open surgery.

You can live a healthy life without your gallbladder. After removal, bile flows directly from your liver into your small intestine.

Your surgeon will discuss whether surgery is appropriate based on your symptoms, overall health and individual circumstances. (Better Health Channel)

Can Gallstones Be Prevented?

There is no guaranteed way to prevent gallstones, but maintaining good overall health may help reduce some risk factors.

A few practical habits can make a difference:

Maintain a healthy weight: If weight management is appropriate for you, aim for gradual changes rather than rapid weight loss.

Choose a balanced diet: Include vegetables, fruit, whole grains, legumes and other fibre-rich foods.

Stay physically active: Regular physical activity supports metabolic health and helps maintain a healthy weight.

Avoid extreme dieting: Very low-calorie diets and rapid weight loss can increase the risk of gallstone formation.

Manage existing health conditions: Conditions such as diabetes may affect your risk. Regular healthcare reviews can help you manage your overall health.

These habits support general wellbeing, but they cannot guarantee that gallstones will not develop.

When Should You Speak With Your GP?

If you have recurring pain beneath your right ribs, unexplained upper abdominal discomfort or symptoms that seem to occur after meals, it is worth speaking with your GP.

Your doctor can assess your symptoms, arrange appropriate investigations and determine whether gallstones or another digestive condition may be responsible.

You should also seek medical advice if gallstones have already been identified on a scan and you are unsure whether they need treatment.

Early assessment can help identify potential complications and guide the most appropriate management.

Understanding Gallstones and Your Digestive Health

Gallstones can be an unexpected finding, particularly when they are discovered during a scan for an unrelated concern.

For some people, they never cause symptoms. For others, they can lead to recurring abdominal pain or complications that require treatment.

While clinicians are reporting more diagnoses in certain settings, the reasons behind the trend are complex. Lifestyle factors, metabolic health and increased use of medical imaging may all play a role.

The most important thing is to understand your symptoms, avoid unnecessary assumptions and seek medical advice when something does not feel right.

Looking after your digestive health starts with paying attention to your body and getting the right support when you need it.
