When Is a Gallbladder Polyp Dangerous?
Gallbladder polyps are most often detected incidentally on ultrasound. The majority are cholesterol polyps and are benign. The decision is based on size, number, growth on follow-up, patient age, coexisting gallstones and other risk factors. Small unchanged polyps are usually followed; polyps above a certain size or with rapid growth may be treated surgically. This page summarises when follow-up versus surgery is considered.
A gallbladder polyp is a projection from the inner wall of the gallbladder, most often benign. The decision depends on size, number, growth rate, age and risk factors. Small stable polyps are usually monitored with ultrasound; larger or higher-risk polyps may require surgery.
Symptoms
Polyps usually cause no symptoms. If gallstones or cholecystitis coexist, abdominal pain, indigestion or nausea may occur.
How is the diagnosis made?
Abdominal ultrasound is the main test. Size, number and growth on follow-up matter. Endoscopic ultrasound (EUS) or CT/MRI may add information in selected cases.
When is surgery needed?
- Polyps ≥10 mm
- Rapidly growing polyps
- Coexisting gallstones or cholecystitis
- Older age and additional risk factors
- Certain liver conditions such as primary sclerosing cholangitis
Follow-up plan
Small unchanged polyps are followed at regular intervals with ultrasound. Growth or new risk factors prompt reassessment.

| Condition | Symptom | Required test | Possible approach | Urgency |
|---|---|---|---|---|
| Gallstones | Pain after fatty meals, bloating | USG, blood tests | Follow-up or surgery | Depends on symptoms |
| Cholecystitis | Prolonged right upper abdominal pain, fever | USG, CRP, WBC | Urgent evaluation / surgery | High |
| CBD stones | Jaundice, dark urine | MRCP, bilirubin | ERCP ± surgery | High |
| Liver cyst | Usually asymptomatic | USG, CT/MRI | Follow-up or surgery | Low–Moderate |
| Hydatid cyst | Right upper abdominal fullness, pain | USG, CT/MRI, serology | Medication ± surgery | Moderate |
