Prof. Dr. Selim Sarı: Why Are Small Gallstones More Dangerous?

Gallstones are hardened deposits of digestive fluid (bile) that can form in your gallbladder, located just under your liver. Small stones, in particular, are considered much more dangerous medically because they carry a high risk of slipping into the bile duct, causing a blockage and potentially life-threatening pancreas inflammation. Experts emphasize that when these small, risky stones are present, surgical intervention is usually inevitable, provided the patient's general health allows it.

• Gallstones are mostly formed by the accumulation of cholesterol or bilirubin.
• Small stones carry a higher risk of falling into the main bile duct and causing blockages compared to larger stones.
• The most common symptom is a severe, agonizing pain starting in the upper right abdomen and radiating to the back and right shoulder.
• Diagnosis is usually simple, painless, and made within minutes using a radiation-free abdominal ultrasound.
• The gold standard in treatment is the complete removal of the gallbladder using a closed (laparoscopic) method.

What Are Gallstones?

Positioned just beneath the liver, the gallbladder is a small, pear-shaped, muscular organ. Its primary job is to store the bile continuously produced by the liver and release it into the duodenum—especially when you eat fatty foods—to aid digestion. When the chemical balance of the fluid inside is disrupted, cholesterol or bilirubin crystals precipitate and merge over time, forming gallstones (cholelithiasis).

These stones can be as small as a grain of sand or, rarely, grow to the size of a golf ball. Often, they can sit silently in the gallbladder for years without causing any symptoms. However, serious health problems begin when the stones move and block the exit of the gallbladder or the bile ducts. This condition, which is quite common in the community, is directly related to dietary habits, age, gender, and genetic predispositions.

Why Are Small Gallstones More Dangerous?

Patients often think that large stones are more frightening, but the medical reality is quite the opposite. As Prof. Dr. Yavuz Selim Sarı, General Surgery Specialist at BHT CLINIC İstanbul Tema Hastanesi, points out, having many small stones in the gallbladder is much riskier than having a single large one. The main reason for this is entirely anatomical.

A large stone is usually trapped inside the gallbladder because it is too big to pass through its narrow duct. However, millimeter-sized small stones can easily drop into the main bile duct when the gallbladder contracts. A stone that falls into the main bile duct completely stops the flow of bile into the intestine, creating a bile duct obstruction. Even more dangerously, these stones can block the opening of the pancreatic duct, leading to a potentially life-threatening condition called acute pancreatitis (inflammation of the pancreas). In such a case, a special endoscopic procedure (ERCP) entered through the mouth is required to reach the duodenum, widen the duct, and remove the stone. For the patient, this means a second, challenging procedure in addition to the standard surgery.

Causes and Risk Factors

Although it is not completely known why gallstones form, a very high concentration of cholesterol in the bile is the most common cause. When the liver secretes more cholesterol than the bile can dissolve, this excess cholesterol crystallizes and turns into stones. Similarly, the excessive production of bilirubin in conditions such as liver cirrhosis or certain blood disorders triggers stone formation. Furthermore, if the gallbladder loses its ability to contract and cannot empty completely, the bile becomes concentrated, leading to stones.

Looking at the risk factors, the incidence is much higher in individuals over forty and in women compared to men. Hormonal changes during pregnancy, obesity, a sedentary lifestyle, and a family history of gallstones significantly increase the risk. Following crash diets for rapid weight loss or fasting for long periods are also major factors that pave the way for stone formation by disrupting the working rhythm of the gallbladder. Since the risk of gallstone formation can also increase during the rapid weight loss period after gastric sleeve surgery, these patients are closely monitored under a doctor's supervision.

Symptoms of Gallstones

Stones in the gallbladder are often called "silent stones" and are discovered by chance when a person goes to the doctor for another complaint and has an ultrasound. However, when the stone begins to block the bile duct, gallstone symptoms appear suddenly and severely. The most typical symptom is pain that starts abruptly in the upper right abdomen, rapidly intensifies, and comes in waves.

This pain usually radiates to the back, between the shoulder blades, or to the right shoulder. Pain attacks often start a few hours after a heavy, fatty meal or during sleep at night, and can last for minutes or even hours. The pain may be accompanied by severe nausea, vomiting, and heavy sweating. Many patients may confuse this condition with a severe stomach spasm or a heart attack. Complaints such as bloating after meals, burping, and indigestion can sometimes appear as early warning signs of gallbladder issues.

How Is It Diagnosed at the Hospital?

When you visit the hospital with complaints of abdominal pain or indigestion, your doctor will first perform a detailed physical examination. The gold standard in diagnosing gallbladder diseases is abdominal ultrasonography. The ultrasound procedure is completely painless, contains no radiation, and clearly shows the size and number of stones in the gallbladder, as well as any thickening in the gallbladder wall.

If it is suspected that the stones have dropped into the bile duct, comprehensive blood tests are requested to evaluate liver enzymes, bilirubin levels, and pancreatic functions. If signs of obstruction or infection are seen in the blood tests, a special MRI scan called MRCP (Magnetic Resonance Cholangiopancreatography) can be performed for a more detailed examination of the biliary tract. Thanks to this imaging method, a three-dimensional map of the biliary tract is created, and exactly where the stone is causing the blockage is determined.

Who Needs Gallbladder Surgery?

Not every patient diagnosed with gallstones needs immediate surgery. According to Prof. Dr. Yavuz Selim Sarı's approach, the treatment decision should be made individually based on the patient's age, general health status, and the risks posed by the stone. If the patient is young, has a long life expectancy, and the stones (especially the small ones) have the potential to cause serious complications in the future, gallbladder surgery is planned.

However, if the patient has severe heart failure, chronic kidney failure, serious lung diseases, advanced cirrhosis, or hematological problems that prevent them from receiving anesthesia, surgical intervention can be risky. In individuals with such comorbidities, doctors perform a detailed risk-benefit analysis. The patient's symptoms and whether a life without surgery is possible are evaluated. If leaving the stone in the gallbladder harms the patient more than the existing risks, the surgery is performed with all necessary medical precautions taken.

The Treatment Process and Laparoscopic Surgery

Methods such as dissolving gallstones with medication or breaking them from the outside with sound waves, as is done with kidney stones, are not preferred in current medical practice. Not only do these methods fail to prevent the reformation of stones, but they can also make the situation more dangerous by increasing the risk of broken small fragments falling into the duct. The definitive treatment is the complete surgical removal of the gallbladder (cholecystectomy).

Today, the standard approach is laparoscopic (closed) surgery. The gallbladder is safely removed with the help of a high-resolution camera and special surgical instruments inserted through a few small incisions of 0.5 to 1 centimeter made in the abdomen. Compared to open surgery, closed surgery offers much less pain, a lower risk of infection, aesthetically smaller scars, and a much faster recovery time. If the stones have fallen into the main bile duct, they are cleared using the ERCP method before the surgery, and the gallbladder is removed a few days later.

Post-Surgery Recovery and Nutrition

Patients who undergo laparoscopic gallbladder surgery are usually discharged on the same or the next day and can return to their daily lives within a few days. After the gallbladder is removed, the body continues to produce bile, but the bile now flows directly into the intestine without being stored. As Prof. Dr. Sarı points out, this situation can cause temporary digestive disorders such as bloating or mild indigestion in some patients. However, these are not major complaints; they are easily corrected with simple medications, and the patient continues their comfortable life.

Paying attention to nutrition in the postoperative period to avoid straining the digestive system speeds up the recovery process:

• Stay away from greasy fried foods, heavy tomato-based sauces, and processed meat products for the first few weeks.
• Reduce your portion sizes and try to consume five or six small meals a day instead of three large ones.
• Regulate your bowel movements by gradually adding fibrous foods (boiled vegetables, peeled fruits, whole grains) to your diet.
• When consuming milk and dairy products, opt for low-fat or fat-free options.
• Pay attention to adequate water consumption; drinking at least two liters of water a day greatly contributes to digestion.

Complications and Risk Groups

Untreated stones that block the bile duct can cause life-threatening complications over time. Inflammation of the gallbladder (acute cholecystitis) manifests with high fever, chills, and unbearable abdominal pain. Jaundice (yellowing of the whites of the eyes and skin) can develop as bile mixes into the blood due to the stone blocking the main bile duct.

In addition, serious infections in the biliary tract (cholangitis) and inflammation of the pancreas (acute pancreatitis) are potentially fatal conditions requiring emergency intervention. Diabetic patients, the elderly, and individuals with suppressed immune systems are in the highest risk group for these complications. Since infection symptoms such as fever or pain may be more subtle in these patients, even mild abdominal pain complaints should be taken much more seriously.

When to See a Doctor

Individuals with suspected or known gallstones should seek medical help without delay when symptoms worsen. Waiting for the pain to pass on its own can lead to the infection spreading into the blood or damaging the pancreas. If you experience any of the following warning signs, you should immediately go to an emergency room or call 112:

• Agonizing pain starting in the upper right abdomen that lasts for hours and makes breathing difficult.
• High fever, shivering, and chills accompanying the pain.
• Noticeable yellowing of the whites of the eyes or skin (jaundice).
• Urine turning dark like tea and stool becoming clay-colored.
• Continuously recurring severe nausea and vomiting intense enough to prevent fluid intake.

Frequently Asked Questions

Do gallstones pass on their own?

Unlike kidney stones, it is not possible for gallstones to be expelled from the body through urine. Stones leaving the gallbladder fall into the main bile duct. This does not allow the stone to be expelled from the body; on the contrary, it blocks the duct, leading to life-threatening problems such as jaundice and pancreatic inflammation.

Do you gain weight after gallbladder surgery?

The removal of the gallbladder does not directly cause weight gain. However, the relief of indigestion complaints and an increase in appetite after surgery can lead to weight gain if portion control is not practiced. You can easily maintain your weight with a healthy and balanced diet plan.

Can small gallstones be dissolved with medication?

Although there are some medications used to dissolve gallstones, this method is generally not preferred in modern medicine. Medical treatment takes a very long time, there is no guarantee that the stones will dissolve completely, and they usually reform when the medication is stopped. Furthermore, there is a high risk of small fragments falling into the bile duct during the dissolving phase.

When can I return to a normal diet after gallbladder removal?

A low-fat diet with frequent meals is recommended for the first few weeks after surgery. The body usually adapts to the bile flowing directly into the intestine within 3 to 4 weeks. After this adaptation period, the vast majority of patients can return to their old normal eating habits without any problems.

What is good for gallstone pain?

Severe pain caused by gallstones is usually a sign of duct obstruction or inflammation and does not go away with herbal remedies applied at home or hot water bottles. To relieve the pain, you must visit a healthcare facility and receive medical treatment; waiting at home increases the risk of complications.
