Gallstones

Overview

Gallstones are hardened deposits that form inside the gallbladder, a small organ located under the liver. The gallbladder stores bile, a digestive fluid that helps break down fats. Gallstones can be as small as grains of sand or as large as pebbles, and a person may have one stone or many.

Many gallstones do not cause symptoms and may be found by chance during tests for another reason. However, if a stone blocks the normal flow of bile, it can cause pain and may lead to inflammation or infection. Gallstones are a common digestive condition, and treatment depends on symptoms, the size and location of the stones, and whether complications are present.

Symptoms

Some people with gallstones have no symptoms at all. These are sometimes called silent gallstones and may not need immediate treatment. When symptoms occur, they often happen after eating, especially after a heavy or fatty meal.

• Sudden pain in the upper right side of the abdomen
• Pain in the upper middle abdomen, below the breastbone
• Pain that spreads to the right shoulder or back
• Nausea or vomiting
• Bloating or indigestion after meals
• Fever or chills, if infection or inflammation develops
• Yellowing of the skin or eyes, known as jaundice
• Dark urine or pale stools if bile flow is blocked

Gallstone pain can last from minutes to several hours. Severe or persistent pain should not be ignored, as it may indicate a blockage or inflammation of the gallbladder or bile ducts.

Causes and Risk Factors

Gallstones form when substances in bile become imbalanced. Bile contains cholesterol, bile salts, and waste products. If bile contains too much cholesterol or if the gallbladder does not empty properly, crystals can form and grow into stones.

Several factors may increase the likelihood of developing gallstones:

• Being female
• Increasing age
• Pregnancy or hormonal changes
• Family history of gallstones
• Being overweight or losing weight very quickly
• A diet high in fat or low in fiber
• Certain liver or blood conditions
• Diabetes or metabolic conditions
• Reduced gallbladder movement or fasting for long periods

Having one or more risk factors does not mean a person will definitely develop gallstones. Likewise, gallstones can occur in people without obvious risk factors.

Diagnosis

A doctor will usually begin by asking about symptoms, medical history, diet, previous illnesses, and any episodes of abdominal pain. A physical examination may include checking the abdomen for tenderness and looking for signs of jaundice or infection.

Imaging tests are commonly used to detect gallstones. An abdominal ultrasound is often the first test because it can show stones in the gallbladder and signs of inflammation. In some cases, other imaging tests may be recommended to examine the bile ducts or look for complications.

Blood tests may be performed to check for infection, inflammation, liver function problems, or blockage of bile flow. If a stone is suspected in the bile duct, additional specialized tests or procedures may be needed. The choice of tests depends on the person’s symptoms and overall condition.

Treatment Options

Treatment for gallstones depends on whether they are causing symptoms or complications. Gallstones found by chance and not causing problems may only require monitoring and follow-up, depending on the doctor’s assessment.

If gallstones cause repeated pain or inflammation, surgery to remove the gallbladder may be recommended. The gallbladder is not essential for survival; after removal, bile flows directly from the liver into the small intestine. Many people can digest food normally afterward, although some may notice temporary changes in digestion.

Gallbladder removal is often performed using minimally invasive techniques, depending on the patient’s condition and the medical team’s evaluation. In emergency situations or complex cases, different surgical approaches may be needed.

If a gallstone is blocking a bile duct, a specialized endoscopic procedure may be used to locate and remove the stone or relieve the blockage. Treatment may also include supportive care in the hospital if there is infection, pancreatitis, or significant inflammation.

Non-surgical approaches may be considered in selected cases, but they are not suitable for everyone and may take time or be less effective for certain types of stones. A gastroenterologist or surgeon can explain the most appropriate options based on test results and overall health.

When to See a Doctor

Medical evaluation is important if you have recurring upper abdominal pain, especially after meals, or if pain spreads to the back or right shoulder. Even if symptoms come and go, gallstones can sometimes lead to complications.

Seek urgent medical care if you experience severe abdominal pain that does not improve, fever, chills, repeated vomiting, yellowing of the skin or eyes, dark urine, pale stools, or confusion. These symptoms may suggest a blocked bile duct, gallbladder infection, or other serious condition requiring prompt assessment.

For international patients, it can be helpful to bring previous ultrasound results, blood tests, imaging reports, and a list of current medical conditions to the appointment. A specialist in gastroenterology can review the findings and recommend a safe, individualized plan.
