Chronic liver disease, also known as cirrhosis, is a progressive condition where healthy liver tissue is replaced with scar tissue, affecting liver function. It can result from various factors like chronic alcohol abuse, viral hepatitis, or fatty liver disease. Symptoms include fatigue, jaundice, swelling in the abdomen, and confusion. Complications include liver failure, portal hypertension, and increased risk of liver cancer. Treatment focuses on managing symptoms, addressing underlying causes, and preventing complications. Lifestyle changes such as abstaining from alcohol and maintaining a healthy diet are essential. In severe cases, liver transplantation may be necessary for survival. Early detection and management are crucial for improving outcomes.
