Causes of Gallstones
Gallstones occur when the liver produces bile that is saturated with dissolved substances and has an excess of cholesterol in it. This may be caused by a relative reduction in bile salts.
Excessive cholesterol may be due to factors such as:
- A high cholesterol diet
- Advancing age
- Excessive refined dietary carbohydrates such as white bread, cakes, and low-fibre cereals
- The use of oral contraceptives
- A genetic disorder featuring excessive cholesterol in the blood (hypercholesterolaemia)
- Liver disease that reduces the levels of bile salts.
