An ultrasound report that mentions a "gallbladder polyp" can be unsettling, especially when you feel perfectly fine. The good news is that most gallbladder polyps are benign and never cause problems. The harder question is which ones deserve attention. In this guide, I explain how we decide when gallbladder polyps need monitoring and when they call for gallbladder removal (cholecystectomy) for patients in San Jose and Los Gatos.
A gallbladder polyp is a small growth that projects from the inner wall of the gallbladder. They are usually discovered by accident, on an ultrasound ordered for something unrelated, and they typically cause no symptoms. Roughly one in twenty adults has one.
Most polyps fall into a few categories:
An ultrasound cannot always tell these apart, so we rely on size, shape, number, growth over time, and your personal risk factors.
Size is the single most useful predictor of risk. Current society guidelines are broadly consistent, though your surgeon will tailor them to you:
These are guideposts, not rules. A 7 mm polyp in a patient with several risk factors may be treated differently from a 7 mm polyp in a younger patient with a clear history.
Beyond size, I look at the whole picture:
Your evaluation usually starts with a review of your ultrasound and symptoms. Depending on what we see, additional steps can include a repeat ultrasound with careful measurement, endoscopic ultrasound for a closer look at the wall, or contrast-enhanced imaging such as CT or MRI. Because the quality of the original ultrasound varies, I often find it useful to have images re-read or repeated before making a decision. If you are unsure whether your findings need action, a consultation at our San Jose office is a good place to start.
If your polyp is small, has a benign appearance, and you have no major risk factors, surveillance ultrasound is a safe and common approach. The aim is to catch growth early. It is important to keep the follow-up appointments, since a missed ultrasound defeats the purpose of watching.
If a polyp is 10 mm or larger, growing, or paired with risk factors, removing the gallbladder eliminates the question entirely. Because the gallbladder is removed whole, the pathologist can examine the polyp and the wall, which gives a definitive answer. If a polyp is suspected to be cancerous, the approach is more involved and may include additional imaging and, occasionally, a different surgical plan, so it is a decision best made with an experienced surgeon.
Removal is done with minimally invasive laparoscopic surgery, and in selected patients with robotic assistance. It is typically outpatient, meaning most patients go home the same day. Most people resume light activity within days and return to desk work within about a week or two, though timing depends on the patient and the work involved. You can read our practical guide to gallbladder surgery recovery and diet for details. Individual results vary.
Living without a gallbladder is very manageable. The liver continues to make bile, which flows directly into the intestine. A minority of patients notice looser stools or fat intolerance at first, which often settles over time.

Most are not. The majority are benign cholesterol polyps. A small number are adenomas or, rarely, cancers, which is why size, growth, and risk factors guide the plan.
Small cholesterol polyps sometimes appear to resolve or change on follow-up imaging, but you should not count on this. There is no diet or supplement proven to dissolve them, so follow the surveillance plan you and your surgeon agree on.
Usually not. If you have right-upper abdominal pain, the cause is often gallstones or another gallbladder condition, and that evaluation is separate from the polyp itself.
It is among the most common operations performed and is usually done laparoscopically as an outpatient procedure. All surgery carries risk, and your surgeon will review them with you. Individual results vary.
