This will cause an inflammation that reduces liver function. The viruses can be spread through blood or semen, contaminated food or water, or close contact with a person who is infected, and the most common types of liver infection are hepatitis viruses, which are Hepatitis A, B and C.

  1. Genetics

Sometimes, these diseases are hereditary. A genetic abnormality can be inherited which can also cause a build-up of substances in the liver that can cause liver damage. Genetic liver diseases include Hyperoxaluria and oxalosis, Hemochromatosis, Alpha-1 antitrypsin deficiency and Wilson’s disease.

Certain lifestyle choices can cause liver disease. Being in the habit of consuming large volumes of alcohol can damage your liver, therefore an alcoholic is at high risk of the disease. Also, individuals with a high-fat consumption or battle with obesity are at risk of having a non-alcoholic fatty liver disease. This is because their body weight can lead to the accumulation of fat in the liver and further damage it.

  1. Cancer

Various cancers and other growths also cause liver disease. This is because cancer and growths negatively affect liver function. Such cancers include liver cancer, bile duct cancer and liver adenoma.

  1. Abnormalities in the immune system
