Everything You Need to Know About Gallstones 2025

What exactly are gallstones?

Imagine the gallbladder as a small pouch that stores a special liquid called bile, which helps us digest fats. Sometimes, this liquid becomes like "sludge" and forms small stones. It's like when you leave salt water in the sun and crystals form, but inside your body.

These "stones" (which doctors call cholelithiasis) can be as small as a grain of sand or as large as a ping-pong ball. Many people have them without knowing it, because they don't always cause problems. In fact, between 10 and 15 out of every 100 people have gallstones, but most don't even realize it!

Interesting Fact

Most gallstones are made primarily of cholesterol (like what we have in our blood), not calcium as many people think. Only some are made of bilirubin, which is what gives our skin a yellow color when we have jaundice.

The important thing to understand is that having gallstones is not automatically dangerous. It's like having freckles on your skin: they're there, but they only matter if they start bothering you. Among digestive disorders, gallstones are one of the most common and best treatable.

Why do they form? The most important risk factors

We doctors have identified several factors that make it more likely for gallstones to form. It doesn't mean that if you have any of these factors you'll definitely get them, but your risk is a bit higher. Think of it as factors that "increase your chances" in a raffle.

Being female

Women have twice the probability as men. This is because female hormones (especially estrogens) make bile have more cholesterol.

Fact: Pregnancy and birth control pills increase this risk even more.

Age

Starting at age 40, the risk increases. It's as if the gallbladder were "aging" and not working as well as before.

Fact: After age 60, up to 1 in 4 people may have stones.

Overweight and obesity

When we have extra weight, especially in the belly, our body produces more cholesterol and the gallbladder doesn't empty as well.

Important: Losing weight very quickly can also cause stones.

Family history

If your mom, dad, or siblings have had gallstones, you're more likely to have them too.

Fact: Genes influence how we handle cholesterol in bile.

Other important factors to consider

• Diabetes: High blood sugar can favor stone formation
• Sedentary lifestyle: Not exercising makes the gallbladder move less
• Very fatty diets: Especially those rich in saturated fats
• Liver diseases: Like hepatitis or cirrhosis
• Crohn's disease: Especially if there have been intestinal surgeries
• Bariatric surgeries: Rapid weight loss can trigger stones

How do I know if I have gallstones? The symptoms

Here comes something very important: most people with gallstones have no symptoms. They're called "silent stones" and can stay there their whole life without causing problems. It's only when stones get "stuck" or the gallbladder becomes inflamed that symptoms appear.

Reassuring fact

Approximately 80% of people with gallstones never develop symptoms. Only 1 in 5 people will have discomfort requiring treatment.

The main symptom: biliary colic

When stones do cause problems, the most typical symptom is what we call "biliary colic." Don't be scared by the name, it has nothing to do with baby colic. It's a pain that:

Where it hurts: In the upper right part of the abdomen (below the ribs) or in the "pit of the stomach." Sometimes it extends to the back or right shoulder.
How long it lasts: Between 15 minutes and several hours. If it lasts less than 15 minutes, it's probably not the stones.
What it's like: An intense, constant pain (doesn't come and go like intestinal cramps). Many describe it as "a knife stuck in."
What triggers it: Often appears after fatty or large meals, especially at night.

Other symptoms that may accompany

Digestive symptoms

• Nausea and vomiting
• Feeling of bloating
• Intolerance to fatty foods
• Frequent burping

Warning signs

• Fever (indicates infection)
• Yellow color in eyes or skin
• Very dark urine
• Very light or gray stools

When to go to the emergency room?

You should seek immediate medical attention if you have:

• Severe pain that doesn't subside with normal painkillers
• High fever (over 101.3°F/38.5°C) along with abdominal pain
• Yellow color in skin or eyes (jaundice)
• Persistent vomiting that prevents you from taking liquids
• Chest pain along with abdominal symptoms

When do I need surgery? Surgery indications

This is probably the question my patients ask me most. The answer is clear: not all gallstones need surgery. In fact, if you have no symptoms, you'll most likely never need to be operated on.

Fundamental principle

Surgery (cholecystectomy) is indicated when stones cause significant symptoms or complications. If there are no symptoms, there's no indication to operate. It's that simple.

Clear indications for surgery

1. Recurrent biliary colic

If you've had several episodes of typical gallbladder pain (biliary colic) lasting more than 15-30 minutes and interfering with your normal life.

Why operate? Because it's very likely that the episodes will repeat and worsen over time.

2. Acute complications (URGENT!)

These situations require immediate surgery, preferably during the same hospitalization:

• Acute cholecystitis: Inflamed/infected gallbladder
• Cholangitis: Infection of bile ducts
• Biliary pancreatitis: Pancreas inflammation from a stone
• Biliary obstruction: Stone stuck in the main duct

Important: These complications can be serious and life-threatening if not treated promptly.

3. Special situations (individual assessment)

In some rare cases, preventive surgery may be considered:

• Porcelain gallbladder: Calcified walls (cancer risk)
• Large gallbladder polyps: Larger than 1 cm
• Very large stones: Larger than 2-3 cm
• Very high-risk patients: Who couldn't tolerate emergency surgery

What type of surgery is performed?

Laparoscopic cholecystectomy: The gold standard

In more than 95% of cases, we perform surgery by laparoscopy (minimally invasive). This means:

Advantages:

• Only 3-4 small incisions (0.5-1 cm)
• Less postoperative pain
• Faster recovery (2-3 days hospital)
• Return to work in 1-2 weeks
• Lower infection risk
• Minimal scars

The procedure:

• Duration: 30-60 minutes
• General anesthesia
• Complete gallbladder removal
• Stones come out with the gallbladder
• Bile ducts remain intact
• You can live perfectly without a gallbladder

What if I have no symptoms but have stones?

This is a very common situation. The answer is clear according to all international medical guidelines:

Preventive surgery is not recommended in people without symptoms. The probability of developing symptoms is low (only 1-2% per year), and surgery, although safe, always has risks. It's better to wait and watch.

Can gallstones be prevented?

Although we can't change factors like age, sex, or genetics, there are many things you can do to reduce your risk of developing gallstones or prevent the ones you already have from causing problems.

Healthy eating

• More fiber: Fruits, vegetables, whole grains
• Healthy fats: Olive oil, nuts, fish
• Less saturated fats: Limit fatty meats and whole dairy
• Regular meals: Don't skip meals, especially breakfast

Regular physical activity

• Moderate exercise: At least 30 min, 5 days/week
• Walking: One of the best options, easy and effective
• Maintain healthy weight: Avoid obesity but no extreme diets
• Lose weight gradually: Maximum 2-4 lbs per week

Beware of extreme diets

Losing weight very quickly (more than 4-6 lbs per week) can paradoxically increase the risk of forming gallstones. If you need to lose weight, do it gradually and under supervision.

Living with gallstones without symptoms

If you've been found to have gallstones but have no symptoms, it's completely normal to feel some anxiety. However, remember: most people with asymptomatic stones live completely normal lives without needing surgery.

Reassurance: Facts that will help you

• Only 1-2% of people with asymptomatic stones develop symptoms each year
• If you haven't had symptoms in 5 years, it's very unlikely you'll develop them
• You can live completely normally: work, travel, exercise
• You don't need a special restrictive diet
• Routine medical checkups are sufficient

What to watch for if you have stones without symptoms?

Although you don't need to be constantly worried, it is important that you know when to see a doctor:

• New abdominal pain in the upper right part
• Persistent nausea without apparent cause
• Sudden intolerance to fatty foods you previously tolerated well
• Any symptom we described earlier

Final message: Gallstones are more common and less serious than you think

Key points to remember

✅ What IS true:

• Gallstones are very common
• Most never cause problems
• When they cause symptoms, there's very effective treatment
• Laparoscopic surgery is very safe
• You can live perfectly without a gallbladder

❌ What you should NOT think:

• That you automatically need surgery
• That it's urgent if you have no symptoms
• That your life will change drastically
• That you need a very restrictive diet
• That it's something "very serious"

As a specialist in digestive system, I've treated thousands of patients with gallstones. Most arrive very worried, but leave reassured when they truly understand their situation. The most important thing is having correct information and a personalized plan.

Remember: having gallstones is not a serious disease by itself. It's a very common condition that, in most cases, can be managed perfectly well with knowledge, prevention, and when necessary, simple and effective treatment.
