One study found that cholesterol stones in particular might have a more potent ability to stimulate inflammation of the gallbladder epithelial cells.

一项研究发现尤其是胆固醇结石更容易刺激胆囊上皮细胞引起炎症反应。

Also though, obesity is often associated with increased levels of cholesterol, meaning that it's also associated with increased risk of cholesterol stones.

此外，肥胖也经常与胆固醇水平升高有关，这也意味着它与增加胆固醇结石形成的风险相关。

Women are typically more at risk than men, because estrogen increases cholesterol stone formation, which is also why use of oral contraceptive pills that contain estrogen increase the risk of cholesterol stones.

相较于男性，通常女性更易患胆系结石，因为雌激素会促进胆固醇结石的形成，这也是为什么使用含雌激素的口服避孕药会增加女性患胆固醇结石的风险。

Gallstones can be made up of bilirubin, called pigment gallstones, or cholesterol, called cholesterol stones, or maybe they're made up of both, and when they roll around and are in contact with the epithelial cells, they can cause inflammation.

胆石可以由胆红素组成，称为胆色素结石；或者由胆固醇组成，称为胆固醇结石；或者由胆红素和胆固醇两种成分混合组成；当胆石四处滚动，碰撞到上皮细胞，可引起炎症反应。
