Liver disease refers to any condition that damages the liver and affects its function. The liver is a vital organ responsible for processing nutrients, filtering the blood, and fighting infections. Damage to the liver can result in various health problems, including fatty liver disease, hepatitis, cirrhosis, and liver cancer. Common symptoms include jaundice (yellowing of the skin and eyes), abdominal pain, swelling, and fatigue.

The liver performs hundreds of essential functions, with one of its key roles being the filtration of toxins from the blood. While it is well-equipped for this job, excessive toxins can overwhelm its capacity, leading to temporary or chronic dysfunction.

When discussing liver disease, providers often refer to chronic conditions that progressively damage the liver over time. These conditions can be caused by viral infections, toxic substances, and certain metabolic disorders. Although the liver has a remarkable ability to regenerate, continuous damage can eventually exceed its capacity to repair itself.
