Gallstones Explained: Biliary Colic, Cholecystitis, and When Surgery Is Necessary

Imagine waking up in the middle of the night with a sharp, unrelenting pain under your right ribs. It doesn’t go away when you move, burp, or pass gas. You feel nauseous. Your stomach feels tight. You’ve never felt anything like this before. This isn’t just indigestion. It’s gallstones-and your body is sending a clear signal that something needs to change.

What Happens When Gallstones Block the Flow

Gallstones are hard deposits that form inside the gallbladder, a small organ tucked under your liver. Most are made of cholesterol-about 80% in Western countries. The rest are pigment stones, formed from excess bilirubin. But here’s the thing: most people with gallstones never know they have them. Up to 80% of those with gallstones live their whole lives without symptoms. The problem starts when one of these stones gets stuck.

When a stone blocks the cystic duct-the tube that carries bile out of the gallbladder-you get biliary colic. This isn’t a dull ache. It’s a steady, intense pain that hits suddenly, peaks within an hour, and lasts between one and five hours. It’s usually felt in the upper right abdomen or just below the breastbone. You might feel it radiating to your right shoulder or back. Unlike stomach flu or gas, this pain doesn’t improve with bowel movements or vomiting. And it doesn’t come in waves-it’s constant until the stone moves.

The pain happens because bile builds up behind the blockage, stretching the gallbladder wall. Your body reacts with inflammation and muscle spasms. Once the stone passes or shifts, the pressure drops, and the pain fades. But if the stone stays stuck for more than a few hours, things get serious.

When Biliary Colic Turns Into Cholecystitis

About 20% of biliary colic episodes lead to acute cholecystitis-inflammation of the gallbladder. This isn’t just worse pain. It’s a medical emergency. The gallbladder becomes swollen, infected, and can even rupture if left untreated.

Signs you’ve moved from colic to cholecystitis:

• Pain lasting more than 6 hours without relief
• Fever or chills
• Nausea and vomiting that won’t stop
• Tenderness when pressing on the right upper abdomen
• Jaundice-yellowing of skin or eyes-if the stone has moved into the common bile duct

This is where things get dangerous. Without treatment, up to 30% of people with symptomatic gallstones end up in the emergency room within five years. And once you’ve had one attack, your odds of another are high. More than 90% of people who’ve had a first episode of biliary colic will have another within 10 years. Two-thirds will have a second one within just two years.

How Doctors Diagnose Gallstones

If you’re having symptoms, your doctor won’t guess. They’ll order an ultrasound. It’s quick, painless, and 95% accurate at spotting gallstones. No radiation. No needles. Just a probe moved over your belly.

Sometimes, if there’s concern about stones in the bile ducts, they’ll use a special ultrasound called an endoscopic ultrasound or an MRI called a MRC (magnetic resonance cholangiopancreatography). Blood tests help check for signs of infection or liver stress-elevated liver enzymes or bilirubin can mean a stone has moved into the duct.

But here’s the problem many patients face: diagnosis delays. Nearly half of people with gallstones see three or more doctors before getting the right answer. Pain gets mislabeled as heartburn, food poisoning, or muscle strain. That’s why knowing the pattern matters-if your pain matches biliary colic, insist on an ultrasound.

Surgery: The Only Reliable Fix

There’s no magic pill that reliably gets rid of gallstones for good. Medications like ursodeoxycholic acid can dissolve small cholesterol stones-but only in 30-50% of cases, and it takes months. Even then, half of those stones come back within five years. Shockwave therapy breaks stones apart, but it’s rarely used now because recurrence is too common.

The only treatment that stops the cycle for good is cholecystectomy-removing the gallbladder. And the gold standard today is laparoscopic cholecystectomy. This isn’t the old-school open surgery with a long scar across your belly. It’s four small cuts, a camera, and tiny tools. Surgeons remove the gallbladder through those tiny ports.

Why it’s the best option:

• Most patients go home the same day or the next morning
• Recovery takes about a week, not a month
• Pain is minimal compared to open surgery
• Success rate is over 95%
• Complication rate is under 2% in experienced hands

In the U.S., over 700,000 of these surgeries are done every year. In Australia, it’s one of the most common procedures performed in public hospitals. The NHS reports that 90% of gallbladder removals now use this method.

Who Should Have Surgery-and Who Should Wait

Not everyone needs surgery right away. But if you’ve had even one clear episode of biliary colic, most doctors will recommend it. Why? Because the next episode could be cholecystitis. Or pancreatitis. Or a blocked bile duct. All of those are far more dangerous-and expensive-to treat.

A study tracking 69 people who avoided surgery found that 64% ended up needing it within 5.6 years. That’s not waiting-it’s delaying the inevitable.

But there are exceptions. For people over 75 with heart disease, diabetes, or other serious health problems, surgery carries more risk. In healthy patients under 65, the 30-day death rate after surgery is less than 0.1%. For those over 75 with three or more conditions, it jumps to 2.8%. That’s why doctors now use risk scores to decide who benefits most.

For high-risk patients who can’t have surgery, a new option emerged in 2023: endoscopic ultrasound-guided gallbladder drainage. It’s not a cure, but it drains the gallbladder without removing it-buying time until the patient is stable enough for surgery.

What to Expect After Surgery

Most people feel better within days. You’ll be up and walking within 4 hours. You’ll sip water within 6 hours. By day two, you’re eating light meals. Most go home within 24 hours.

Some side effects are normal:

• Diarrhea for a few weeks-your body is adjusting to bile flowing directly into the intestine
• Gas and bloating after fatty meals
• Mild shoulder pain from the gas used during surgery

About 12% of people report ongoing diarrhea. A smaller group-around 6%-get post-cholecystectomy syndrome: persistent pain, bloating, or nausea. Often, this is due to undiagnosed issues like bile duct stones or sphincter of Oddi dysfunction-not the surgery itself.

One patient from Cleveland Clinic had 17 biliary colic episodes over 18 months. After surgery, her pain vanished. Within 10 days, she was back to walking her dog. Two weeks later, she returned to work. That’s the typical story.

What’s Changing in Gallstone Care

The field is moving fast. Enhanced Recovery After Surgery (ERAS) protocols are now standard in most hospitals. These include:

• Minimizing fasting before surgery
• Using pain control without heavy opioids
• Getting patients walking within hours
• Starting food immediately after surgery

These changes have cut hospital stays by 30% and reduced readmissions by 25%. Another trend is single-incision laparoscopic surgery (SILS), where the surgeon uses just one small cut near the belly button. But it’s not better-just cosmetic. Studies show it has a 20% higher complication rate than standard laparoscopic surgery.

Meanwhile, rising obesity rates are driving more gallstones. In the U.S., nearly 40% of adults are obese-a major risk factor. Women are two to three times more likely to get them than men. Hispanic populations have a 45% higher risk than non-Hispanic whites.

What You Can Do Now

If you’ve had one episode of biliary colic:

• Don’t wait for the next one. Talk to a surgeon.
• Get an ultrasound if you haven’t already.
• Ask about ERAS protocols-make sure your hospital uses them.
• Don’t be afraid to ask: ‘Is this the right time for surgery?’

If you’re over 75 or have serious health issues, ask your doctor about a risk assessment. Surgery might still be the best choice-but it needs careful planning.

If you’re avoiding surgery because you’re scared of side effects, remember: the pain you’re living with now is the same pain you’ll keep feeling. The surgery doesn’t cause chronic problems-it ends them.

What Happens if You Do Nothing?

You might think, ‘I’m fine now.’ But gallstones don’t disappear. They don’t heal. They just wait. And every time they block a duct, you risk:

• Acute cholecystitis
• Common bile duct obstruction
• Acute pancreatitis
• Perforation or infection

These aren’t just uncomfortable-they’re life-threatening. Emergency surgery for cholecystitis is harder, riskier, and costs three times more than planned surgery. The longer you wait, the higher the chance you’ll need open surgery instead of laparoscopic. And recovery? It takes months.

There’s no safe way to live with symptomatic gallstones. The only way to stop the cycle is to remove the source.
