Gallbladder stones are mainly seen in adults, more in women than men, and their incidence increases with age after the age of 40. Stones are cholesterol stones or a mixture of cholesterol-based stones and black bile pigment stones. The risk factors for gallbladder stones, mainly cholesterol stones, include: 1. Gender: women are more likely to have gallbladder stones than men. 2. Age: The chance of stones increases with age. Obesity: obese people are more likely to have stones than normal people. 4, pregnancy: pregnant women have an increased risk of gallstones because during pregnancy, the cholesterol content in the bile is higher and the movement of the gallbladder is weakened. 5, birth control pills and hormone therapy: oral contraceptives or hormone therapy can increase the risk of stone formation. 6, rapid weight loss: rapid weight loss can cause the formation of gallbladder stones. 7, high blood triglycerides: gallbladder stones are likely to occur in people with high levels of triglycerides in the blood. 8, Crohn’s disease: people suffering from Crohn’s disease are more likely to develop gallbladder stones. For people with the above risk factors, regular ultrasound examinations are recommended for early detection and early treatment.
