Do You Need Your Gallbladder Removed? Polyps, Symptoms and the Facts

Reviewed by Dr Goutham Sivasuthan, FRACS — June 2026

In short

• The gallbladder stores bile; you can live perfectly well without it.
• Most gallbladder polyps are small and harmless — size is the key factor, with around 10 mm a common threshold for considering removal.
• Surgery is usually recommended for symptomatic gallstones, larger or growing polyps, or other higher-risk features.
• Removal (cholecystectomy) is typically keyhole day surgery with a quick recovery.

“Do I really need it out?” is the question almost every gallbladder patient asks. The answer depends on whether your gallbladder is causing problems now, or carries enough future risk to justify removing it. Here is how surgeons actually weigh that up.

What the gallbladder does (and why you can live without it)

The gallbladder is a small pouch under the liver that stores and concentrates bile, releasing it to help digest fatty meals. When it is removed, the liver simply delivers bile straight to the bowel instead. Most people notice no lasting difference, which is why removal is one of the most common and well-tolerated operations performed.

Gallbladder polyps: when size matters

Polyps are growths on the gallbladder lining, often found incidentally on an ultrasound done for another reason. The great majority are small, benign cholesterol polyps. The decision to watch or remove comes down mainly to size and risk:

Polyp size	Typical approach
Under 6 mm	Usually safe to monitor with periodic ultrasound
6–9 mm	Monitor; remove if growing or other risk factors
10 mm or larger	Removal usually recommended

Other risk factors count too. Rapid growth, age over 50, a single sessile (flat) polyp, gallstones alongside the polyp, or primary sclerosing cholangitis all lower the threshold for surgery, even below 10 mm.

Symptoms that point to a gallbladder problem

• Pain in the right upper abdomen, often after fatty meals, sometimes spreading to the back or right shoulder.
• Episodes of pain lasting from 30 minutes to a few hours (biliary colic).
• Nausea or vomiting with the pain.
• Fever, persistent pain, or yellowing of the skin or eyes — these suggest complications and need urgent review.

Who actually needs surgery

Surgery is generally recommended when the gallbladder is clearly causing symptoms or has caused a complication, and for polyps or stones that carry enough future risk. Removal is usually advised for:

• Symptomatic gallstones (recurrent biliary pain).
• Gallstone complications — infection (cholecystitis), pancreatitis or a blocked bile duct.
• Gallbladder polyps 10 mm or larger, or smaller polyps that are growing or higher-risk.

If your gallbladder is silent — stones or a tiny polyp found by chance, with no symptoms — watchful monitoring is often the right call rather than rushing to operate.

Life after gallbladder removal

A cholecystectomy is almost always done laparoscopically (keyhole) as day surgery, with most people back to normal activity within one to two weeks. A minority notice looser or more frequent stools for a while as the body adjusts; this usually settles, and a lower-fat diet in the early weeks helps. Long term, the vast majority of patients eat normally with no restrictions.

Frequently asked questions

Are gallbladder polyps dangerous?

Most are small, benign cholesterol polyps that never cause trouble. The concern is the small proportion that can be or become cancerous, which is why size and growth are tracked and larger polyps are removed.

What size gallbladder polyp needs surgery?

Around 10 mm is a common threshold for recommending removal. Smaller polyps are usually monitored, but surgery may be advised earlier if a polyp is growing, you are over 50, or there are other risk factors.

Can you live without a gallbladder?

Yes. The liver delivers bile directly to the bowel after the gallbladder is removed, and most people digest food normally. Some notice looser stools at first, which typically settles.

Is gallbladder removal major surgery?

It is a common, well-established operation, almost always done with keyhole surgery as a day procedure. Most people recover within one to two weeks, though it is still real surgery and is only recommended when justified.
