Study Notes
Fatty Liver (Steatosis)
- The main pathological change in fatty liver (steatosis) is the accumulation of excess triglycerides in liver cells.
Causes of Fatty Liver
- Fatty liver has two main categories of causes:
- Nutritional: resulting from overconsumption of carbohydrates and fats
- Metabolic: resulting from disorders such as diabetes, obesity, and insulin resistance
VLDL Synthesis and Fatty Liver
- When the liver's capacity to synthesize very low-density lipoprotein (VLDL) is exceeded, excess triglycerides accumulate in the liver, contributing to fatty liver.
High Carbohydrate Diet and Fatty Acid Synthesis
- A high carbohydrate diet stimulates fatty acid synthesis in the liver, leading to an increase in triglyceride production and accumulation.
Overfeeding and Fatty Liver
- Overfeeding of carbohydrates and fats leads to fatty liver as the excess energy is converted to triglycerides, which are stored in the liver, causing its dysfunction.
Test your knowledge of fatty liver (steatosis) with this quiz. Explore the causes, pathological changes, and implications of abnormal fat accumulation in liver cells. From understanding the percentage increase in fats to identifying the progression to fibrotic changes and impaired liver function, this quiz covers key aspects of fatty liver.
