Question 1

What is the Meaning of Liver Steatosis?

Accepted Answer

Liver steatosis, commonly known as fatty liver, refers to the excessive accumulation of lipids, primarily triglycerides, within the hepatocytes, the main cells of the liver. This condition signifies an imbalance in hepatic lipid metabolism, leading to intracellular fat deposits. It represents a deviation from normal liver physiology, impacting cellular function.

Question 2

What is the Context of Liver Steatosis?

Accepted Answer

This hepatic condition is frequently observed within the broader context of metabolic dysfunction, often associated with insulin resistance, dyslipidemia, and systemic inflammation. The liver, a central organ in metabolism, becomes a storage site for excess fat, which can influence its role in glucose regulation, detoxification, and protein synthesis. It serves as a critical indicator of overall metabolic health status.

Question 3

What is the Significance of Liver Steatosis?

Accepted Answer

The presence of liver steatosis holds significant clinical importance as it can progress to more severe forms of liver disease, including non-alcoholic steatohepatitis (NASH), characterized by inflammation and liver cell damage. Untreated, this progression may lead to fibrosis, cirrhosis, and ultimately liver failure, necessitating transplantation. It also correlates with increased cardiovascular risk.

Question 4

What is the Mechanism of Liver Steatosis?

Accepted Answer

The development of liver steatosis primarily stems from an imbalance between the influx and synthesis of fatty acids in the liver and their subsequent oxidation or export. Factors such as increased delivery of free fatty acids from adipose tissue, enhanced de novo lipogenesis within the liver, and impaired very-low-density lipoprotein (VLDL) secretion contribute to triglyceride accumulation. Insulin resistance plays a pivotal role by promoting hepatic lipogenesis.

Question 5

What is the Application of Liver Steatosis?

Accepted Answer

Liver steatosis is a prevalent diagnosis in clinical practice, particularly among individuals with obesity, type 2 diabetes mellitus, and metabolic syndrome. Management strategies typically involve comprehensive lifestyle modifications, including sustained weight reduction through dietary changes and regular physical activity. Addressing underlying metabolic disturbances is fundamental to reversing or stabilizing the condition and preventing progression.

Question 6

What is the Metric of Liver Steatosis?

Accepted Answer

Diagnosis of liver steatosis often involves imaging modalities such as abdominal ultrasound, computed tomography (CT) scans, or magnetic resonance imaging (MRI), which can detect fat accumulation. Transient elastography (e.g., FibroScan) assesses liver stiffness, indicating fibrosis severity. While not direct measures of fat, elevated liver enzymes like alanine aminotransferase (ALT) and aspartate aminotransferase (AST) may suggest hepatocyte injury.

Question 7

What is the Risk of Liver Steatosis?

Accepted Answer

Untreated liver steatosis carries substantial risks, including the potential for progression to non-alcoholic steatohepatitis (NASH), which involves inflammation and hepatocellular injury. This inflammatory process can lead to hepatic fibrosis, eventually advancing to cirrhosis and an increased risk of hepatocellular carcinoma. It also contributes to systemic metabolic complications and elevates cardiovascular disease risk.
