Is the chance of developing gallbladder stones increased after gastric sleeve surgery?

Hi Vertedo,
Thank you for your great question — it’s very smart to be thinking ahead as you prepare for your vertical sleeve gastrectomy (VSG), also known as gastric sleeve surgery.
Yes, it’s true that the chance of developing gallstones after gastric sleeve surgery can increase, especially during the period of rapid weight loss. In our practice, we see about 5% of patients develop gallbladder issues after surgery. This happens because rapid weight loss can cause changes in the bile, making it easier for stones to form.
The good news is that when gallbladder problems do occur, they are typically very easy to resolve, often with a simple outpatient gallbladder removal surgery.
If you are concerned about gallstones, you may request a medication called Ursodiol, and we can have a conversation together to see if it’s a good fit for you and your concerns. Ursodiol can be very effective in helping prevent gallstone formation during the rapid weight loss phase.
Most importantly, the health benefits of gastric sleeve surgery — including improved heart health, better blood sugar control, reduced joint pain, and increased energy — far outweigh the small potential risk of developing gallbladder issues. You are making a powerful investment in your long-term health.
Wishing you the very best as you move forward — you’re taking a truly exciting step!

Taking ursodeoxycholic acid helps prevent gallstones, highly recommended, you will not regret it, if you have a family history of stones.

After VSG, there is an increased risk of developing gallstones because rapid weight loss can cause changes in bile composition, making it more likely for stones to form. This happens because the liver releases more cholesterol into bile, and since you’ll be eating less, the gallbladder won’t contract as often, allowing bile to sit longer, which promotes stone formation.
To reduce this risk, doctors often prescribe Ursodiol for about six months after surgery. Ursodiol helps prevent gallstones by lowering the cholesterol content in bile. Staying hydrated, following your surgeon's dietary plan, and staying active after surgery can also help reduce your risk. If you’re concerned, you should talk to your surgeon about whether Ursodiol is right for you and what other steps you can take to prevent stones.
