| Remark | - Cholesterol is mainly synthesised in the liver and the mucosa of the small intestine. It serves as a starting substance for bile acids, steroid hormones and cell membrane components.
- Hypocholesterolaemia is caused by liver failure (reduced synthesis capacity), malabsorption or maldigestion, acute inflammatory responses, starvation or cachexia.
- Hypercholesterolaemia is caused by cholestasis and liver disease, endocrine disorders (e.g. hypothyroidism, Cushing’s syndrome), obesity and lipid metabolism disorders or dietary factors (high-fat diet).
