Severity
Uncommon
Category
Serious / Rare
Why It Happens
Rapid weight loss is a well-known risk factor for gallstone formation. When the body breaks down fat rapidly, the liver secretes extra cholesterol into bile, which can crystallize into stones. Reduced food intake also means the gallbladder contracts less frequently, allowing bile to stagnate and stones to form. This risk exists with any method of rapid weight loss.
Timeline
Risk increases during periods of active, rapid weight loss — typically the first 6-12 months of treatment. Gallstones may be asymptomatic or can cause sudden, severe pain. Risk persists as long as weight loss is ongoing.
Management Tips
Do not skip meals — regular eating stimulates gallbladder contraction
Include small amounts of healthy fats in your diet to keep bile flowing
Stay hydrated
Maintain a moderate rate of weight loss when possible
Report any upper right abdominal pain to your doctor promptly
Some doctors may recommend ursodiol (ursodeoxycholic acid) for prevention in high-risk patients
When to See Your Doctor
Seek immediate medical attention for severe pain in the upper right abdomen (especially after eating), pain that radiates to the right shoulder or back, nausea and vomiting with abdominal pain, fever with abdominal pain, or yellowing of skin or eyes (jaundice)

Can Ozempic cause gallstones?
GLP-1 medications do not directly cause gallstones, but the rapid weight loss they produce is a well-known risk factor for gallstone formation. Clinical trials for semaglutide reported gallbladder-related events in 1-3% of patients. This risk exists with any method of significant weight loss.
What are the signs of gallstones on GLP-1 medication?
Watch for sudden, intense pain in the upper right abdomen (often after eating fatty foods), pain radiating to the right shoulder blade, nausea and vomiting with abdominal pain, and in severe cases, fever or jaundice. Many gallstones are asymptomatic.
How do you prevent gallstones while losing weight on GLP-1?
Eat regular meals (do not skip), include small amounts of healthy fats to stimulate bile flow, stay hydrated, and aim for steady rather than extremely rapid weight loss. Your doctor may prescribe ursodiol for prevention if you are at high risk.
