Liver disease refers to a range of conditions that affect the liver's ability to function properly. Common types include hepatitis, fatty liver disease, and cirrhosis. These conditions can result from factors such as excessive alcohol consumption, viral infections, or obesity. Symptoms may include fatigue, jaundice, and abdominal pain. The liver plays a crucial role in digestion, metabolism, and detoxification. When it is damaged, it can lead to serious health complications. Early detection and treatment are essential for managing liver disease and preventing further damage. Lifestyle changes, such as a healthy diet and regular exercise, can help maintain liver health.
