The causes of gallstones can be broadly divided into the following three points: 1. Increased cholesterol, which can lead to the inability to drain all the bile, resulting in the accumulation of cholesterol crystals in the gallbladder, which eventually becomes gallstones. Most of these patients are caused by long-term overeating, excessive greasy food intake, and high protein content. 2. bile pigment stones, which cause bile to accumulate in the gallbladder instead of being drained into diabetes, can form gallstones over time. Most of them are due to the fact that most people in society nowadays often do not eat breakfast, irregular diet or long-term disorderly diet, and over time gallstones are formed.
