Gallstones are one of the most common digestive problems in the United States, yet many people have them without ever knowing it. The clearest way to know you have gallstones is when they block the flow of bile and cause sudden, severe pain in the upper right part of your belly. This pain, often called a gallbladder attack, is the hallmark symptom that leads most people to seek medical help. If you have never had this specific type of pain, you may still have gallstones, but they are considered silent and usually do not require treatment.
What Exactly Are Gallstones?
Gallstones are hardened deposits of digestive fluid that form inside your gallbladder. The gallbladder is a small, pear-shaped organ located just beneath your liver on the right side of your abdomen. Its main job is to store bile, a fluid your liver produces to help digest fats.
Most gallstones are made primarily of cholesterol. When your liver secretes more cholesterol than your bile can dissolve, the excess can crystallize and form stones. Another type, pigment stones, form when there is too much bilirubin in the bile. Bilirubin is a waste product produced when your red blood cells break down.
Stones can be as small as a grain of sand or as large as a golf ball. You can have one large stone, many small ones, or a mixture of both. None of this matters much unless a stone moves into a duct and causes a blockage.
How Do U Know If You Have Gallstones: The Classic Symptoms
The most reliable way to know you have gallstones is to experience a gallbladder attack. This is not a vague stomachache. It is a distinct, often unforgettable type of pain.
The pain typically hits suddenly and intensifies quickly. It is usually located in the upper right portion of your abdomen, directly under your ribs. The pain can also radiate to your right shoulder blade or between your shoulder blades. Many people describe it as a sharp, cramping, or gnawing sensation that does not let up.
Attacks often follow a heavy or fatty meal, especially one eaten in the evening. The pain usually lasts from 30 minutes to several hours. If the pain lasts longer than a few hours or is accompanied by a fever, that is no longer a simple attack — it is a sign of a complication and requires immediate medical attention.
Nausea and vomiting can accompany the pain. Some people also notice bloating or indigestion, but these symptoms alone are too common and nonspecific to reliably point to gallstones.
What a Gallbladder Attack Feels Like
If you have never had one, it helps to understand the quality of the pain. People who have experienced gallbladder attacks often say the pain is severe enough that they cannot sit still. They may pace, shift positions, or find it hard to get comfortable. This is different from a typical stomach ulcer or gas pain, where lying still often helps.
The pain is caused by a stone temporarily blocking the cystic duct, the tube through which bile leaves the gallbladder. When the duct is blocked, the gallbladder contracts against the obstruction, building up pressure. That pressure is what creates the intense pain. When the stone passes or falls back, the pressure releases and the pain fades.
Because the pain can mimic a heart attack, especially when it radiates to the chest or back, it is wise to have any severe upper abdominal pain evaluated promptly.
When Gallstones Become an Emergency
Gallstones are dangerous when they cause complications. A stone that fully blocks the flow of bile can lead to inflammation of the gallbladder, a condition called acute cholecystitis. This is a medical emergency.
Seek emergency care immediately if you have any of these warning signs:
- Pain so severe you cannot sit still or find a comfortable position
- Fever or chills
- Yellowing of your skin or the whites of your eyes (jaundice)
- Clay-colored stools or dark tea-colored urine
- Persistent vomiting
- Pain that lasts longer than five hours
Fever with abdominal pain is especially concerning. It suggests an infection has developed, which can spread rapidly if not treated. Jaundice indicates that a stone has moved into the common bile duct, blocking bile flow from the liver. Both situations require urgent medical care, often with surgery or endoscopic procedures.
Silent Gallstones: When You Have Them But Feel Nothing
Most people with gallstones never have symptoms. Studies consistently show that the majority of gallstones are found incidentally — during an ultrasound or CT scan done for an unrelated reason. These are called silent gallstones.
Having silent gallstones does not mean you need treatment. Current medical guidelines do not recommend surgery for asymptomatic gallstones. The risk of a silent stone becoming symptomatic is relatively low — roughly 2 to 3 percent per year in the first decade after discovery. Many people live their entire lives with gallstones and never know it.
The exception is for people with certain conditions that raise the risk of gallbladder cancer, such as a calcified gallbladder wall or stones larger than 3 centimeters in diameter. In these rare cases, a doctor may recommend removing the gallbladder even without symptoms. This is a decision made on an individual basis with your physician.
How Doctors Confirm You Have Gallstones
Physical symptoms alone are not enough for a diagnosis. The gold standard for detecting gallstones is an abdominal ultrasound. This painless imaging test uses sound waves to create a picture of your gallbladder and liver. Ultrasound detects gallstones with a high degree of accuracy and is almost always the first test ordered.
If your doctor suspects a stone has moved into the common bile duct, other tests may be needed. These can include a magnetic resonance cholangiopancreatography (MRCP), which is an MRI scan focused on the bile ducts, or an endoscopic ultrasound. Blood tests can also help by showing elevated liver enzymes or bilirubin levels, which suggest bile flow is blocked.
If you experience the classic symptoms, do not try to self-diagnose. Several other conditions can produce similar pain, including peptic ulcers, pancreatitis, and even some heart conditions. A proper medical evaluation is the only reliable way to know for certain.
Who Gets Gallstones and Why
Gallstones are common, affecting roughly 10 to 15 percent of the adult population in the United States. Certain groups face a higher risk. Women are about twice as likely as men to develop gallstones, largely because estrogen increases cholesterol levels in bile. Pregnancy, hormone replacement therapy, and birth control pills all raise the risk for the same reason.
Age matters as well. The likelihood of developing gallstones increases steadily after age 40. Obesity is another major risk factor because it causes the liver to produce more cholesterol. Rapid weight loss, such as after bariatric surgery or a very low-calorie diet, can also trigger stone formation. People with diabetes, cirrhosis, or certain blood disorders like sickle cell anemia are at higher risk too.
Family history plays a role. If a close relative has had gallstones, your own risk is higher. Ethnic background also matters — Native Americans and Mexican Americans have the highest rates of gallstones in the United States.
Treatment Options: What Happens Next
If you have had one gallbladder attack, the likelihood of having more is high. About two-thirds of people who experience a first attack will have recurrent symptoms within two years. For this reason, surgery is the standard recommendation once symptoms have occurred.
The most common procedure is laparoscopic cholecystectomy, which removes the gallbladder through several small incisions. Most people go home the same day or the next day and recover fully within a week or two. Recovery from open surgery, which requires a larger incision, takes longer and is reserved for complicated cases.
You can live a completely normal life without a gallbladder. The organ is helpful but not essential. After removal, bile flows directly from your liver into your small intestine. Some people experience looser stools or digestive changes after surgery, especially after eating fatty meals, but these effects usually improve over time.
Non-surgical treatments exist but are rarely used. Oral medications that dissolve cholesterol stones take months or years to work and have a high recurrence rate. Shock wave lithotripsy, which breaks stones apart using sound waves, is rarely performed today. Surgery remains the definitive and most effective treatment for symptomatic gallstones.
Frequently Asked Questions
Can gallstones go away on their own?
Gallstones do not dissolve or disappear on their own. Small stones can pass through the bile duct into the intestine, but most stones remain in the gallbladder indefinitely.
How long does a gallbladder attack last?
A typical gallbladder attack lasts between 30 minutes and several hours. Pain lasting longer than five hours or accompanied by fever requires immediate emergency care.
What does gallbladder pain feel like compared to gas?
Gallbladder pain is typically a steady, severe ache in the upper right belly that may radiate to the back or right shoulder, while gas pain is usually diffuse and changes with movement or passing gas. Gallbladder pain often makes it hard to find a comfortable position.
Can you have gallstones without a gallbladder attack?
Yes, most people with gallstones have no symptoms at all. Silent gallstones are found incidentally during imaging tests and generally require no treatment.
