Hepatitis is an inflammation of the liver, often caused by viral infections. There are several types, including Hepatitis A, Hepatitis B, and Hepatitis C, each transmitted in different ways. Symptoms can include fatigue, jaundice (yellowing of the skin and eyes), and abdominal pain. In addition to viral causes, hepatitis can also result from excessive alcohol consumption, certain medications, or autoimmune diseases. Early diagnosis and treatment are important to prevent serious complications, such as liver damage or cirrhosis. Vaccines are available for some types, like Hepatitis A and Hepatitis B, to help prevent infection.
