• Hepatitis :

  • Hepatitis describes an inflammation of the liver. A number of different viruses (e.g. A, B and C ) can cause hepatitis.

  • There are also non-viral forms of hepatitis.

  • Hepatitis can lead to cirrhosis, liver cancer and liver failure.

  • Steatosis :
  1. Fatty liver (steatosis) is an abnormal deposition of certain fats (triglycerides or cholesterol) inside liver cells.

  2. People with fatty liver may feel tired or abdominal discomfort.

  • Cirrhosis :
  • Cirrhosis is the irreversible replacement of a large amount of normal liver cells with nonfunctioning scar cells. It develops in damaged liver conditions.

  • Alcoholism and hepatitis are the most common causes of cirrhosis.

  • Symptoms include poor appetite, weight loss, and feeling weak, sick, and tired.

  • Fibrosis :
  • Liver fibrosis is the replacement of normal liver cells by extracellular matrix proteins like collagen.

  • It occurs in most types of chronic liver diseases.

  • Advanced liver fibrosis results in cirrhosis and liver failure.

  • If damage is acute (sudden) and limited, the liver commonly repairs itself by regenerating new liver cells.

  • However, repeated damage leads to scarring (fibrosis).
