Gallstones
Gallstones are solid particles that form in the gallbladder, which can vary in size and may or may not cause symptoms. Many individuals may have gallstones without experiencing any issues. Treatment options are available for those who do experience symptoms, but each case is unique.
Digestive System- What causes gallstones to form?MedlinePlusMay 2026
Gallstones form when substances in your bile harden into solid pieces. This usually happens when bile sits in your gallbladder too long or when it contains too much cholesterol or other materials.
- How do gallstones block bile flow?MedlinePlusMay 2026
Gallstones block bile flow by getting stuck in the bile ducts, which are the tubes that carry bile from your gallbladder to your small intestine. When a stone blocks the duct, bile can't flow through, causing pain and other symptoms.
- Can I digest food without a gallbladder?MedlinePlusMay 2026
Yes, you can digest food without a gallbladder because bile has other ways to reach your small intestine. Your liver still makes bile to help digest fat, so your body can work normally without the gallbladder.
- Why am I more likely to get gallstones if I'm overweight?MedlinePlusMay 2026
Extra weight can change how your body makes and stores bile, which makes gallstones more likely to form. People who are overweight are at higher risk for gallstones, along with older adults, women, and certain ethnic groups.
- Will my diet affect gallstone attacks?MedlinePlusMay 2026
Yes, diet can affect gallstone attacks—eating fatty or greasy foods often triggers pain because your gallbladder contracts to release bile when you eat. Eating smaller, healthier meals may help reduce attacks.
