Introduction
Causes of Gallstones:
1. Sedentary lifestyle with minimal physical activity—reduces gallbladder muscle contractility;
2. Obesity—individuals with excess body weight represent the highest-risk population for gallstone formation;
3. Multiple pregnancies—hormonal and physiological changes during pregnancy predispose women to biliary dysfunction;
4. Skipping breakfast—leads to increased bile concentration due to prolonged fasting;
5. Frequent snacking after meals—impairs digestion, nutrient absorption, and bile excretion;
6. Cirrhosis—results in diminished gallbladder contractile function.
Gallstones, also known as cholelithiasis, refer to the formation of stones within the biliary tract—including the gallbladder or bile ducts—and biliary tract infections are relatively common. So, what are the causes of gallstones? Below is an explanation.
Causes of Gallstones
1. Sedentary Lifestyle
Insufficient physical activity and exercise lead over time to decreased contractility of the gallbladder smooth muscle, delayed bile emptying, bile stasis, and precipitation of cholesterol crystals—conditions conducive to gallstone formation. Additionally, elevated estrogen levels in women affect hepatic formation of glucuronidated bilirubin, increasing unconjugated bilirubin. Estrogen also impairs gallbladder emptying, promoting bile stasis and thereby facilitating stone formation. Postmenopausal women receiving estrogen therapy exhibit a significantly higher incidence of gallstones.
2. Obesity
Regular consumption of high-fat, high-sugar, and high-cholesterol beverages or snacks directly contributes to weight gain. Obesity is a major risk factor for gallstone disease. Research indicates that individuals whose body weight exceeds the normal standard by more than 15% have a fivefold higher incidence of gallstones compared with those at healthy weight. Women aged over 40 who are overweight constitute the highest-risk group for gallstones, partly because estrogen promotes greater cholesterol accumulation in bile.
3. Multiple Pregnancies
During pregnancy, biliary function often becomes dysregulated, resulting in impaired smooth muscle contraction and bile retention within the gallbladder. Concurrently, serum cholesterol levels rise during gestation, increasing the likelihood of cholesterol precipitation and gallstone formation. Women with multiple pregnancies face an even higher risk.
4. Skipping Breakfast
Many people today skip breakfast. Prolonged omission of breakfast leads to increased bile concentration, fostering bacterial proliferation and promoting gallstone formation. Conversely, consistent breakfast consumption stimulates partial bile release, reduces the viscosity of overnight-stored bile, and lowers the risk of gallstone development.
5. Snacking After Meals
The habit of sitting and snacking after meals may be one reason behind the rising incidence of gallstones in China. When seated in a curled position, intra-abdominal pressure increases and gastrointestinal motility is restricted, impairing digestion, absorption, and bile excretion. Prolonged sitting after meals hinders reabsorption of bile acids, disrupting the cholesterol-to-bile acid ratio in bile and predisposing cholesterol to precipitate and deposit.
6. Cirrhosis
In patients with cirrhosis, reduced hepatic estrogen inactivation results in elevated systemic estrogen levels. Combined with diminished gallbladder contractility, impaired gallbladder emptying, varicose biliary veins, and elevated serum bilirubin, these factors collectively promote gallstone formation.
The above outlines the primary causes of gallstones. We hope this information is helpful to you.
