Hepatitis is swelling and inflammation of liver. Hepatitis is most commonly caused by viral infection. Other causes of Hepatitis include autoinmune hepatitis (a Disease occuring when the body makes antibodies against the liver tissue) and hapatitis that occurs as a secondary result of medications, drugs, toxins and alcohol. Viral infections of the liver that are classified as hepatitis are: hepatitis A, B, C, D, and E viruses. Hepatitis A is a milder version of the disease, whereas hepatitis D is more severe. Treatment options vary depending on what form of hepatitis is diagnosed, and what caused it. Some forms of hepatitis are preventable. Causes of Non-viral Hepatitis is Alcohol and Autoimmune disease. Hepatitis can be caused by liver damage from excessive alcohol consumption. This is sometimes referred to as “alcoholic hepatitis.” The alcohol causes the liver to swell and become inflamed. Other toxic causes include overuse of medication or exposure to poisons. The immune system may mistake the liver as a harmful object and begins to attack it, hindering liver function. Signs and symptoms of acute hepatitis appear quickly. They include: fatigue, flu-like symptoms, dark urine, pale-colored stool, abdominal pain, loss of appetite, unexplained weight loss, yellow skin and eyes (may be signs of jaundice).
