Cirrhosis is a complication of liver disease which involves loss of liver cells and irreversible scarring of the liver. Typically, the disease comes on slowly over months or years. Early on, there are often no symptoms.  As the disease worsens, a person may become tired, weak, itchy, have swelling in the lower legs, develop yellow skin, bruise easily, have fluid build up in the abdomen, or develop spider-like blood vessels on the skin. Cirrhosis is most commonly caused by alcohol, hepatitis B, hepatitis C, and non-alcoholic fatty liver disease. Non-alcoholic fatty liver disease is due to a number of reasons, including being overweight, diabetes, high blood fats, and high blood pressure.  Cirrhosis is characterized by the replacement of normal liver tissue by scar tissue. These changes lead to loss of liver function. Diagnosis is based on blood testing, medical imaging, and liver biopsy.  Image illustrates hepatic steatosis and chronic hepatitis.  Trichrome stain

Wet rough asphalt black bitumen road pavement surface abstract grunge texture close-up top view background banner.\nBitumen is a sticky, black, highly viscous liquid or semi-solid form of petroleum. In the U.S., it is commonly referred to as asphalt. It may be found in natural deposits or may be a refined product, and is classed as a pitch. Before the 20th century, the term asphaltum was also used.\nTarmacadam is a road surfacing material made by combining crushed stone, sand, and tar. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces. The terms \
