Potential signs of liver disease include yellowed eyes and skin; swelling in the legs, ankles and abdomen; itchy skin; altered colors of urine and stool; and chronic fatigue, notes the Mayo Clinic. Vomiting, nausea, loss of appetite and bruising unusually easily are also possible signs of liver trouble.
Several different types of conditions lead to liver disease, explains the Mayo Clinic. Viruses and parasites sometimes infect the liver, leading to inflammation and hindered liver function. The most common viruses that attack the liver are hepatitis A, B and C, and they usually spread through semen, blood, close contact with an infected person or contaminated food.
Anomalies in the immune system also affect liver function at times. Primary biliary cirrhosis, primary sclerosing cholangitis and autoimmune hepatitis are all autoimmune diseases that attack the liver, reports the Mayo Clinic. Genetic liver diseases such as Wilson's disease, hyperoxaluria and oxalosis, and hemochromatosis all result from a gene that causes items to aggregate in the liver.
Various types of cancer, including liver cancer, bile duct cancer and such growths as liver adenoma also hinder liver function, according to the Mayo Clinic. Lifestyle-related causes include ongoing alcohol abuse and the aggregation of fat in the liver. Monitoring one's diet allows the avoidance of these last reasons for liver trouble.
