Acute liver failure is loss of liver function that occurs quickly — in days or weeks — usually in a person who has no preexisting liver disease. It's most commonly caused by a hepatitis virus or drugs, such as acetaminophen. Acute liver failure is less common than chronic liver failure, which develops more slowly.
Liver failure can develop slowly or rapidly, depending on the cause and the condition of the liver. Chronic liver failure: The most common type of liver failure is chronic, which can take months or years to develop.
Stage 1: Inflammation
In the early stages of liver disease, the liver will become swollen or inflamed as the body's natural response to injury. Liver inflammation, or hepatitis, can also occur when there are more toxins in the blood than the liver is able to manage. The earlier the diagnosis, the better.
It takes upwards of ten years for alcohol-related liver disease to progress from fatty liver through fibrosis to cirrhosis to acute on chronic liver failure. This process is silent and symptom free and can easily be missed in primary care, usually presenting with advanced cirrhosis.
The liver damage associated with mild alcoholic hepatitis is usually reversible if you stop drinking permanently. Severe alcoholic hepatitis, however, is a serious and life-threatening illness.
Long-term intake of more than 30 g of absolute alcohol per day increases the risk of alcoholic liver disease; liver disease is nearly certain in long-term consumption in excess of 80 g of absolute alcohol per day.
A person can remain asymptomatic for years, although 5–7% of those with the condition will develop symptoms every year. Decompensated cirrhosis: People with decompensated cirrhosis already experience symptoms and complications.
The risk of disease was twice as high in women than men, but only in the dose range 3–8 drinks/day. Only 4% of individuals consuming more than 6 drinks daily had cirrhosis and only 10% had any evidence of liver disease at all.
So what does liver pain feel like? It manifests in different ways, but a common form is a dull throbbing. For some people, it occurs as a sharp, stabbing pain. Sometimes the pain migrates to other nearby areas, such as the right shoulder blade and the back.
As the liver becomes more severely damaged, more obvious and serious symptoms can develop, such as: yellowing of the skin or whites of the eyes (jaundice) swelling in the legs, ankles and feet caused by a build-up of fluid (oedema) swelling in your abdomen caused by a build-up of fluid known as ascites.
Acute liver failure can develop quickly in an otherwise healthy person, and it is life-threatening. If you or someone you know suddenly develops a yellowing of the eyes or skin; tenderness in the upper abdomen; or any unusual changes in mental state, personality or behavior, seek medical attention right away.
Your liver can keep working even if part of it is damaged or removed. But if it starts to shut down completely—a condition known as liver failure—you can survive for only a day or 2 unless you get emergency treatment.
During stage 1, cirrhosis is so mild it's often difficult for physicians to detect. The most common symptom is fatigue. The cirrhosis is still reversible during this stage, but not enough liver tissue has been damaged to produce obvious symptoms of disease.
Over time, liver disease can cause cirrhosis (scarring). As more scar tissue replaces healthy liver tissue, the liver can no longer function properly. Left untreated, liver disease can lead to liver failure and liver cancer.
Acute liver failure strikes fast. You can experience loss of liver function within weeks or even days. It may happen suddenly without showing any symptoms. Common causes of acute liver failure include poisoning from mushrooms or drug overdose, which can occur from taking too much acetaminophen (Tylenol).
People with cirrhosis in Class A have the best prognosis, with a life expectancy of 15 to 20 years. People with cirrhosis in Class B are still healthy, with a life expectancy of 6 to 10 years. As a result, these people have plenty of time to seek sophisticated therapy alternatives such as a liver transplant.
Myth: I might have cirrhosis, but the liver will regenerate and heal itself naturally. Fact: The liver is a highly regenerative organ but only if it's still healthy enough to do so and doesn't have extensive scar tissue. Once cirrhosis is present, your liver's regeneration becomes very limited.
Often, cirrhosis is first detected through a routine blood test or checkup. To help confirm a diagnosis, a combination of laboratory and imaging tests is usually done.
The liver is part of the body's natural detoxification system, which helps filter out toxins. Foods that support liver health include berries, cruciferous vegetables, beans, whole grains, nuts, and fatty fish. Coffee and green tea contain antioxidants that are helpful for liver health.
Severe drinking may require three months to a year to fully regenerate the liver to its original capacity and functionality. Over time, the liver can heal itself from damages caused by alcoholic fatty liver disease and hepatitis.
