Liver failure occurs when the liver loses its ability to function properly. This vital organ helps process nutrients, filter toxins, and produce important proteins. When the liver is damaged, it can lead to a buildup of harmful substances in the body, causing serious health issues. There are two main types of liver failure: acute and chronic. Acute liver failure happens suddenly, often due to factors like viral infections or overdose of medications. Chronic liver failure develops gradually, usually as a result of long-term conditions such as alcohol abuse or hepatitis. Early diagnosis and treatment are crucial for better outcomes.
