The liver is one of the hardest-working organs in the human body. Every day it performs hundreds of important jobs that keep us alive and healthy.
It helps digest food, stores vitamins and minerals, removes harmful substances from the blood, produces proteins that help the blood clot, controls many chemical processes, and supports the body’s immune system. Because the liver is involved in so many vital functions, serious damage to this organ can affect almost every part of the body.
Liver failure happens when the liver has become so badly damaged that it can no longer carry out these essential tasks. This is a life-threatening condition that needs urgent medical care.
In many cases, liver damage develops slowly over many years because of long-term diseases such as chronic hepatitis, heavy alcohol use, or non-alcoholic fatty liver disease. Sometimes liver failure can also happen suddenly because of severe infections, certain medicines, poisoning, or other serious injuries to the liver.
One of the challenges with liver disease is that it often causes very few symptoms in its early stages. Many people do not realize there is a problem until the damage has become severe. As liver function continues to worsen, however, the body begins to show clear warning signs that should never be ignored.
One of the best-known signs is jaundice, which causes the skin and the whites of the eyes to turn yellow. This happens because the damaged liver can no longer remove bilirubin, a yellow waste product produced when old red blood cells break down.
As bilirubin builds up in the bloodstream, the yellow color becomes more noticeable. Dark urine and pale-colored stools may also develop.
Another common symptom is swelling in the abdomen, known as ascites. When the liver becomes scarred, blood flow through the organ becomes more difficult, increasing pressure in nearby blood vessels.
At the same time, the liver produces fewer proteins such as albumin, which normally help keep fluid inside blood vessels. As a result, fluid leaks into the abdomen, causing the belly to become swollen and uncomfortable. Swelling can also affect the legs, feet, and ankles.
As liver failure progresses, harmful substances that are normally removed from the blood begin to build up. One of these substances is ammonia. When ammonia reaches the brain, it can cause a condition called hepatic encephalopathy.
People may become forgetful, confused, sleepy, or have trouble concentrating. Family members may notice unusual behavior, personality changes, or slurred speech. In severe cases, patients may lose consciousness or fall into a coma, making emergency treatment essential.
Digestive problems are also very common. Many people experience nausea, vomiting, poor appetite, and a feeling of fullness after eating only a small amount of food. Because they eat less and their bodies cannot process nutrients normally, significant weight loss and muscle wasting may occur over time.
Extreme tiredness is another major symptom. Unlike ordinary tiredness that improves with rest, the fatigue caused by liver failure can be overwhelming. Even simple daily activities such as getting dressed, walking around the house, or preparing meals may become difficult because of weakness and lack of energy.
The liver also produces many of the proteins needed for normal blood clotting. When these proteins are no longer made in enough amounts, bleeding becomes much easier.
People may bruise after very minor bumps, develop frequent nosebleeds, bleeding gums, or notice blood in their vomit or stools. Internal bleeding can become life-threatening and requires immediate medical attention.
Many people with advanced liver disease also develop severe itching. This happens because substances normally carried away in bile begin to collect in the body and irritate the skin. The itching may become so intense that it disrupts sleep and greatly reduces quality of life.
Kidney problems may also develop in advanced liver failure. This serious complication, known as hepatorenal syndrome, causes kidney function to decline even though the kidneys themselves may not be permanently damaged. Without prompt treatment, this condition can rapidly become life-threatening.
Doctors determine the best treatment based on the cause of liver failure and how advanced the disease has become. Treatment may include medicines to manage complications, draining excess abdominal fluid, improving nutrition, treating infections, stopping alcohol use when appropriate, and carefully monitoring kidney and brain function.
For some patients with severe liver failure, a liver transplant offers the best chance of long-term survival.
The good news is that many causes of liver disease can be reduced through healthy lifestyle choices. Maintaining a healthy weight, limiting alcohol, getting vaccinated against hepatitis when recommended, avoiding unnecessary medicines that can damage the liver, and managing conditions such as diabetes may all help protect liver health.
People with known liver disease should attend regular medical appointments so that any worsening can be detected as early as possible.
Recognizing the warning signs of liver failure is extremely important. Yellow skin, swelling of the abdomen, confusion, severe tiredness, easy bleeding, persistent itching, or sudden kidney problems should never be ignored. Early medical care can improve symptoms, reduce complications, and in some cases save a person’s life.
