Gallstones (cholelithiasis) are hard deposits that form in the gallbladder, often made of cholesterol or bilirubin. Many people have gallstones without symptoms, but when stones block the flow of bile, they can cause episodes of abdominal pain, nausea, or more serious complications such as infection or pancreatitis. Risk is influenced by factors like age, sex, weight changes, and pregnancy. While asymptomatic gallstones may not require treatment, symptomatic or complicated cases often require medical evaluation and, in many cases, surgical removal of the gallbladder.

What Are Gallstones?

Gallstones (cholelithiasis) are hard, pebble-like deposits that form in the gallbladder. The gallbladder is a small organ beneath the liver that stores bile, a fluid that helps digest fats.

Gallstones are usually made of cholesterol or bilirubin. They can range in size from tiny grains of sand to stones as large as a golf ball.

Why Do Gallstones Form?

Gallstones form when bile becomes too thick or out of balance. This can happen when:

• There is too much cholesterol in bile, which can form crystals
• The gallbladder does not empty completely or often enough
• Bile sits in the gallbladder too long and becomes concentrated

Over time, these crystals can grow and harden into gallstones.

Risk Factors for Gallstones

Several factors increase the risk of developing gallstones, including:

• Female sex
• Age 40 and older
• Obesity or rapid weight loss
• Pregnancy
• Diabetes
• Certain blood disorders
• Certain medications
• Family history of gallstones

Symptoms of Gallstones

Many people with gallstones never develop symptoms. When gallstones cause irritation, infection of the gallbladder, or interfere with the normal flow of bile symptoms may include:

• Sudden, intense pain in the upper right or center of the abdomen
• Pain that may radiate to the back or right shoulder
• Nausea or vomiting
• Pain that occurs after eating fatty meals
• Jaundice (yellowing of the skin or eyes) if bile flow is blocked
• Fever or chills if infection develops

Considerations During and After Pregnancy

Gallbladder pain can sometimes be mistaken for pregnancy-related discomfort. Persistent upper right abdominal pain, especially after eating or radiating to the back or right shoulder, is not typical of pregnancy and may indicate gallbladder disease.

If you are pregnant or recently postpartum and experiencing ongoing or unusual symptoms, proper evaluation can help determine whether the gallbladder may be contributing.

How Are Gallstones Diagnosed?

Gallstones are typically identified through a combination of imaging and blood tests, along with a review of symptoms and medical history. These evaluations help determine whether gallstones are present, whether the gallbladder is inflamed or infected, and whether complications may be affecting nearby organs.Which tests are used depends on your symptoms, and our providers can help decide which evaluations are most appropriate.

Complications of Gallstones

While many people with gallstones never develop problems, approximately 1 in 5 individuals will eventually experience symptoms or complications that require treatment.

Common complications include:

• Inflammation of the gallbladder (cholecystitis)
• Gallstones in the bile duct which can lead to infection
• Inflammation of the pancreas (pancreatitis)

If you develop persistent abdominal pain, fever, vomiting, or yellowing of the skin or eyes, seek medical care right away.

What Are The Treatment Options for Gallstones?

Gallstones that do not cause symptoms often do not require immediate treatment. In some situations your physician may discuss whether preventive gallbladder removal could be beneficial.

If gallstones are causing symptoms, even if they come and go, talking with your physician can help determine the best approach for you. Your physician will consider factors such as the pattern and severity of your symptoms, your overall health, and your preferences when recommending a treatment plan.

When gallstones interfere with the normal flow of bile or lead to infection (such as cholecystitis, bile duct blockage, or pancreatitis), the situation becomes urgent and requires prompt medical care, typically including surgery.

Natural and Dietary Approaches

Many patients ask about natural or dietary approaches to managing gallstones. Healthy eating, staying well hydrated, maintaining a stable weight, and avoiding rapid weight loss can support gallbladder health and may help reduce the risk of forming new gallstones. Diets that are lower in saturated fat and include fiber rich foods may also help lessen symptoms for some people.

However, current medical evidence shows that diet and supplements alone do not reliably dissolve or remove existing gallstones. When symptoms continue or complications develop, surgery remains the most effective and dependable treatment option.

Life After Gallbladder Removal

If the gallbladder is removed, most people feel well and resume their normal routines shortly after surgery. Some people may experience changes in bowel habits or mild digestive symptoms after gallbladder removal but, overall, people live comfortably without ongoing limitations, with the body naturally adjusting over time.

Gallstones are common and often go unnoticed. When symptoms develop, thoughtful evaluation and individualized care can help reduce the risk of complications. Our gastroenterology team is here to help guide evaluation and treatment decisions based on your symptoms and personal risk factors.
