Liver disease is a broad term that includes a variety of disorders that impact the structure and function of the liver and cause a wide range of symptoms. Fatigue, edema, jaundice (yellowing of the skin and eyes), and abdominal pain are common warning signs. Pale stools, black urine, nausea, vomiting, and appetite loss are also common. There may be bruising easily, itchy skin, and ankle and leg edema. The causes range from fatty liver disease, alcoholism, autoimmune diseases, and viral infections like hepatitis. Stages of liver disease progression include fibrosis and inflammation, cirrhosis, and even liver failure or malignancy. Effective treatment and the avoidance of problems depend heavily on early detection, lifestyle modifications, and medical supervision.
