Gallstones are one of the most common gallbladder conditions, affecting millions of people worldwide. While some people have gallstones without ever knowing it, others experience sudden, intense gallbladder pain that can significantly affect their quality of life and may require urgent medical attention.
As a licensed Naturopathic Doctor and primary care healthcare provider with nearly 20 years of clinical experience, I frequently help patients identify digestive symptoms, determine whether the gallbladder may be contributing to their health concerns and investigate the underlying factors that increase the risk of developing gallstones.
What are gallstones?
One of the most common questions patients ask is, "What are gallstones?"
Gallstones are hardened deposits that develop inside the gallbladder. The gallbladder is a small organ located beneath the liver that stores bile a digestive fluid produced by the liver that helps digest fats. Gallstones can vary greatly in size, number and composition. Some people develop a single stone, while others may have dozens or even hundreds of smaller stones. Although many people mistakenly refer to them as liver stones, gallstones develop within the gallbladder or bile ducts—not within the liver itself.
Where are gallstones located?
People often wonder, "Where are gallstones located?" Gallstones are most commonly found:
- Inside the gallbladder
- Within the cystic duct
- In the common bile duct (less commonly)
When stones become lodged in one of these ducts, they can block the normal flow of bile and trigger severe symptoms.
Common gallstones symptoms include upper right abdominal pain, nausea, bloating and pain that may radiate to the back or right shoulder, although many people have no symptoms at all.
What causes gallstones?
Many patients ask, "What causes gallstones?" or "What causes gallstones?" The exact gallstones causes depend on several factors, but most develop when the balance of substances in bile becomes disrupted.
Common gallstone causes include:
- Excess cholesterol in bile
- Excess bilirubin
- Poor gallbladder emptying
- Obesity
- Rapid weight loss
- Pregnancy
- Diabetes
- Increasing age
- Family history
- Certain medications
- High-fat, low-fibre diets
Most gallstones develop gradually over many years.
The 4 types of gallstones
Understanding the 4 types of gallstones helps healthcare providers determine possible contributing factors and guide treatment decisions. Although cholesterol stones are by far the most common, there are several recognized gallbladder stone types.
1. Cholesterol gallstones: The most common type, accounting for approximately 80% of cases. These form when bile contains too much cholesterol.
2. Pigment gallstones: These dark stones develop from excess bilirubin and are more common in individuals with liver disease or certain blood disorders.
3. Mixed gallstones: Many stones contain varying amounts of cholesterol, calcium salts, bile pigments and proteins.
4. Calcified (calcium-containing) stones: These contain higher amounts of calcium and may appear more clearly on imaging studies.
What are the symptoms of gallstones?
Many people have gallstones without symptoms. These are called "silent gallstones." When symptoms occur, they often develop suddenly after eating, particularly after large or fatty meals.
Common gallstones symptoms include:
- Sudden upper right abdominal pain
- Pain beneath the breastbone
- Pain that radiates into the back or right shoulder
- Nausea
- Vomiting
- Bloating
- Indigestion
- Pain lasting from 30 minutes to several hours
The classic gallbladder pain often begins shortly after eating and may awaken someone from sleep.
Gall bladder symptoms
Some of the most common gall bladder symptoms include:
- Upper abdominal discomfort
- Sharp or cramping pain
- Nausea after fatty meals
- Burping
- Bloating
- Feeling overly full after eating
- Pain radiating to the right shoulder blade
These symptoms may come and go as stones temporarily block the flow of bile.
Signs of gallstones
Recognizing the signs of gallstones early may help prevent complications. Possible signs include:
- Recurrent pain after meals
- Episodes of nausea
- Pain following greasy foods
- Tenderness beneath the right ribs
- Fever (if infection develops)
- Yellowing of the skin or eyes (jaundice)
If fever or jaundice develops, urgent medical assessment is necessary.
Early signs of gallstones
The early signs of gallstones are often subtle and may include:
- Mild indigestion
- Occasional bloating
- Feeling uncomfortable after fatty meals
- Intermittent upper abdominal pain
- Mild nausea
Because these symptoms overlap with many digestive conditions, proper evaluation is important.
Symptoms of gallstones in women
Although gallstones occur in both men and women, symptoms of gallstones in women are more common because female hormones increase the amount of cholesterol secreted into bile.
Women may experience:
- Pain after eating
- Bloating
- Nausea
- Right upper abdominal pain
- Pain during pregnancy
- Symptoms associated with rapid postpartum weight loss
The increased prevalence of gallbladder conditions in women is thought to be related to estrogen, pregnancy and hormonal changes throughout life.
How big are gallstones?
Many patients ask, "How big are gallstones?" The answer varies tremendously as a typical gallstone size ranges from:
- As small as a grain of sand (1–2 mm)
- Several millimetres
- Up to several centimetres in diameter
Some rare gallstones may exceed 5 cm. A person's symptoms are not always related to the gall bladder stone size. Small stones may actually pose a greater risk of entering the bile ducts than larger stones.
Which size of gallbladder stone is dangerous?
Patients frequently ask, "Which size of gallbladder stone is dangerous?" There is no single dangerous size; instead, the risk depends on:
- Whether the stone blocks a bile duct
- Whether inflammation develops
- Whether infection occurs
- Whether pancreatitis develops
Even very small stones can cause serious complications if they become lodged in the common bile duct.
What is the normal size of gallbladder stone?
Technically, there is no normal size of gallbladder stone because gallstones are not a normal finding. Gallstones of any size may remain symptom-free for years, while others quickly produce significant symptoms. Healthcare providers consider the patient's symptoms and imaging findings far more important than stone size alone.
How to prevent gallstones
Many patients ask, "How to prevent gallstones?" or "How to prevent gallstone?" While not every case can be prevented, several healthy lifestyle habits may reduce risk.
These include:
- Maintaining a healthy body weight
- Avoiding rapid weight loss
- Eating adequate dietary fibre
- Including healthy fats in moderation
- Exercising regularly
- Managing diabetes
- Eating regular meals rather than prolonged fasting
Supporting overall metabolic health appears to be one of the most effective ways to lower risk.
What to avoid with gallstones
Patients often ask "What to avoid with gallstones?" Although individual tolerance varies, many people benefit from limiting foods that trigger symptoms, including:
- Fried foods
- Highly processed foods
- Large, high-fat meals
- Excess saturated fat
- Heavy cream sauces
- Fast food
- Excessive alcohol
Keeping a food and symptom diary may help identify personal triggers.
Maintaining a healthy weight, avoiding rapid weight loss, eating a fibre-rich diet and staying physically active may help prevent gallstones and support long-term gallbladder health.
How are gallstones diagnosed?
Healthcare providers may use:
- Medical history
- Physical examination
- Ultrasound (the preferred first test)
- Blood tests
- MRI or MRCP
- CT scan in selected cases
Ultrasound is highly effective for identifying gallstones and assessing inflammation.
When should you seek immediate medical attention?
Seek urgent medical care if gallbladder symptoms are accompanied by:
- Fever
- Chills
- Persistent severe pain
- Yellow skin or eyes
- Dark urine
- Pale stools
- Repeated vomiting
These symptoms may indicate a blocked bile duct or gallbladder infection that requires immediate treatment.

FAQ’s
What is the main cause of gallstones?
The main cause of gallstones is an imbalance in bile, the digestive fluid stored in the gallbladder. Gallstones can form when bile contains too much cholesterol, too much bilirubin, or when the gallbladder does not empty properly. Many gallstones are made mainly of cholesterol.
What food is bad for gallstones?
Foods that are high in fat may trigger gallbladder pain in some people, especially fried foods, greasy fast food, processed meats, full-fat dairy, butter-heavy foods, pastries and rich desserts. A lower-fat, higher-fiber eating pattern may help reduce gallbladder attacks for some people. Rapid weight loss or very low-calorie dieting can also increase the risk of gallstones.
What is the most common treatment for gallstones?
Many people with gallstones have no symptoms and may not need treatment. When gallstones cause repeated pain, inflammation, or other symptoms, the most common treatment is gallbladder removal surgery, called cholecystectomy. In some cases, other treatments may be considered, but surgery is commonly used for symptomatic gallstones.
What are the beginning signs of gallstones?
Gallstones may cause no symptoms at first. When symptoms begin, they often include sudden pain in the upper right abdomen or upper middle abdomen, especially after eating a fatty meal. The pain may spread to the back or right shoulder and may come with nausea, vomiting, bloating, or indigestion.
What tests confirm gallstones?
Doctors usually confirm gallstones with a medical history, physical exam, blood tests and imaging tests. An abdominal ultrasound is commonly used first. Other tests may include CT scan, MRI, cholescintigraphy/HIDA scan, or ERCP if a stone is suspected in the bile duct.
Final thoughts
Gallstones are extremely common and may remain silent for years before causing symptoms. Understanding what are gallstones, recognizing the signs of gallstones and knowing what causes gallstones can help you seek appropriate care before complications develop. If you experience recurring gallbladder pain, particularly after meals, it is important to have your symptoms properly evaluated. Early diagnosis can help determine the cause of your symptoms and guide the most appropriate treatment plan.
As a primary care Naturopathic Doctor, I work with patients to identify both the immediate cause of digestive symptoms and the broader lifestyle and metabolic factors that influence long-term gallbladder and digestive health.
