What Are Gallbladder Stones?

Gallbladder stones (gallstones) are hardened deposits—typically of cholesterol or bile pigments—that form inside the gallbladder, a small pear-shaped organ under your liver responsible for storing bile. Medically, this condition is called cholelithiasis.

Most people—about 60% to 80%—with gallstones remain asymptomatic, often never knowing they're there. Symptoms typically occur when a stone blocks the bile duct, leading to a painful episode known as biliary colic.

In this blog, the best multispeciality hospital in Siliguri delves into various aspects of gallbladder stones such as causes, risk factors, symptoms, prevention, and how gallbladder stones lead to cancer. 

Why Are Women at Greater Risk of Gallstones?

Women are generally at a higher risk of developing gallstones, and the primary reason lies in the effect of female hormones. Estrogen increases cholesterol levels in bile, while progesterone slows down the emptying of the gallbladder. This combination makes women more prone to stone formation, especially in their younger years.

Age and hormonal influence: Before the age of 40, women are almost three times more likely to develop gallstones compared to men. Pregnancy further increases this risk. However, as women grow older, the difference in risk narrows, and by age 60, women are only slightly more at risk than men.

Estrogen therapy and oral contraceptives: Hormone therapy, particularly estrogen taken in pill form, significantly increases the risk. Oral contraceptive pills may also raise the risk, especially during the first decade of use.

Obesity and weight loss: Obesity is another contributing factor since excess body fat leads to higher estrogen production. Interestingly, rapid weight loss or very low-calorie diets can also trigger gallstone formation because they disrupt bile balance, causing cholesterol to crystallize. This is why gallstones are common after weight-loss surgery, and in some cases, surgeons recommend gallbladder removal during the same procedure.

Other risk factors: People with diabetes, spinal cord injuries, or other conditions that reduce gallbladder contractions are also more susceptible. In addition, genetic predisposition can play a role in gallstone development.

For women, especially those with risk factors such as pregnancy, obesity, or hormone therapy, early consultation with the best gastroenterologist in Siliguri is crucial. A specialist can provide timely guidance on preventive measures, lifestyle adjustments, and treatment options to protect long-term gallbladder health

Recent Statistics & Trends:

• Gallstones affect between 5% and 10% of people, with higher rates observed in women and those in North India.
• Modern lifestyles are causing gallstones to appear more frequently in younger and working-age individuals.

Causes of Gallstones:

The exact reason gallstones form isn’t always clear. However, they may develop when:

• Excess cholesterol in bile: Normally, bile contains enough substances to dissolve cholesterol released by the liver. But if the liver produces more cholesterol than bile can handle, the excess may crystallize and eventually form stones.
• Excess bilirubin in bile: Bilirubin is a chemical released when red blood cells break down. Conditions such as liver cirrhosis, biliary tract infections, and certain blood disorders can cause the liver to produce too much bilirubin, which contributes to gallstone formation.
• Poor gallbladder emptying: If the gallbladder does not empty completely or often enough, bile becomes concentrated, which increases the chance of stones forming.

Types of Gallstones:

Gallstones can be of different types, depending on their composition:

• Cholesterol gallstones – The most common type, often yellow in color. These are made mostly of undissolved cholesterol, though they may also contain other substances.
• Pigment gallstones – These are dark brown or black and form when bile contains excess bilirubin.

Risk Factors for Gallstones:

Certain factors make some people more prone to developing gallstones, including:

• Age 40 or older
• Being overweight or obese
• Sedentary lifestyle (lack of physical activity)
• Pregnancy
• High-fat or high-cholesterol diet
• Low-fiber diet
• Family history of gallstones
• Diabetes
• Blood disorders (e.g., sickle cell anemia, leukemia)
• Rapid weight loss
• Use of estrogen-containing medications, such as oral contraceptives or hormone therapy
• Liver disease

Symptoms to Watch Out For:

Gallstones may remain silent, but complications can bring on:

• Severe, steady upper right-abdominal pain lasting hours (biliary colic) 
• Nausea, vomiting, and indigestion—especially after fatty meals
• Fever, jaundice (yellowing of skin and eyes), and unusual dark urine—signs of complications like cholecystitis, cholangitis, or pancreatitis

How to Prevent Gallstones:

Gallstones often develop silently, but simple lifestyle choices can greatly reduce your risk. Prevention mainly focuses on maintaining a healthy gallbladder and balanced bile flow.

Maintain a Healthy Weight: 

• Being overweight increases cholesterol levels in bile, which promotes gallstone formation.
• Aim for gradual, steady weight loss (about 0.5–1 kg per week). Crash diets or sudden weight loss increase the risk instead of reducing it.

Follow a Balanced Diet: 

• Eat more fiber: Whole grains, fresh fruits, and vegetables support healthy digestion and bile balance.
• Choose healthy fats: Small amounts of olive oil, fish oil, and nuts can keep the gallbladder contracting normally.
• Limit fried and processed foods: Too much unhealthy fat and refined carbs raise cholesterol in bile.
• Avoid very low-calorie diets, which slow down gallbladder emptying and encourage stone formation.

Stay Physically Active: 

• Regular exercise (at least 30 minutes a day, 5 days a week) helps regulate weight, improves digestion, and reduces gallstone risk.

Stay Hydrated:

• Drink enough water daily, especially in hot climates, to prevent bile from becoming concentrated.

Be Cautious With Hormone Therapy:

• Women on estrogen therapy or oral contraceptives may face higher risk. Always consult your doctor for safer alternatives if needed.

Monitor Health Conditions

• Conditions like diabetes, liver disease, or rapid weight-loss treatments (such as bariatric surgery) raise gallstone risk. Regular medical check-ups help in early detection.

Gallstones can often be prevented through a balanced diet, gradual weight management, hydration, and regular activity. If you are at higher risk — due to family history, obesity, or other health conditions, consulting the best gastroenterologist at the best multispeciality hospital in Siliguri can help you with personalized prevention strategies and timely treatment if needed.

How Gallbladder Stones Can Lead to Cancer

Gallstones are not only painful but can also increase the risk of gallbladder cancer (GBC) — a rare but aggressive cancer. The connection between gallstones and cancer lies in chronic irritation and inflammation of the gallbladder wall.

Chronic Inflammation: When gallstones remain in the gallbladder for years, they constantly irritate and inflame its lining. This long-term inflammation can cause changes in the gallbladder cells, making them more likely to turn cancerous.

Size of Gallstones Matters: 

• Large gallstones (greater than 3 cm) carry the highest risk.
• The longer they remain untreated, the greater the chance of precancerous or cancerous changes.

Mucosal Damage & Cellular Changes: Repeated irritation from stones can lead to:

• Thickening of the gallbladder wall
• Abnormal tissue growth (metaplasia or dysplasia)
• Over time, these abnormal cells may progress into cancer.

Other Contributing Factors: 

• Women with gallstones have a higher risk due to hormonal factors.
• Chronic infections of the bile duct, poor lifestyle habits, and genetic predisposition can add to the danger.

Conclusion:

If you have gallstones or symptoms such as persistent abdominal pain, jaundice, or unexplained weight loss, don’t ignore them. Consulting the best gastroenterologist at the best multispeciality hospital in Siliguri ensures early treatment, lowering both complications and cancer risk.
