The liver is a vital organ that plays a central role in metabolism, detoxifying the body from harmful substances, producing bile for digestion, and regulating blood clotting. Diseases such as fatty liver, hepatitis, cirrhosis, and liver cancer can affect these functions and have serious health consequences. Fatty liver is often linked to obesity and unhealthy habits, while hepatitis is caused by viruses. Cirrhosis develops after long-term liver damage and can lead to significant impairment. Maintaining liver health through a healthy lifestyle is crucial in preventing these conditions.
