The liver is a vital organ responsible for numerous functions in our body, including detoxification, metabolism, and the production of essential proteins. When the liver suddenly loses its ability to function properly, it results in a life-threatening condition known as acute liver failure (ALF). In this blog, we will delve into the causes of acute liver failure and explore ways to prevent it.

Understanding Acute Liver Failure

Acute liver failure is characterized by the rapid deterioration of liver function within a matter of days or weeks. It can occur suddenly, without any pre-existing liver disease, making it a critical medical emergency. There are various reasons behind this catastrophic event, and understanding its causes is crucial for prevention. Autoimmune disease and Wilson’s disease can also be the leading causes of Acute liver failure.

What Are The Common Causes of Acute Liver Failure?

Viral Infections

Viral hepatitis, especially hepatitis A, B, and E, can lead to acute liver failure. These viruses can attack and damage liver cells, causing a sudden decline in liver function.

Drug-Induced Liver Injury

Certain medications can harm the liver when taken in excessive doses or inappropriately. Acetaminophen (paracetamol) overdose is a notable example, as it can quickly lead to acute liver failure.

Excess Alcohol Consumption

Chronic alcohol consumption can gradually damage the liver, but acute liver failure can occur if a heavy drinker suddenly stops or significantly reduces their alcohol intake.

Autoimmune Hepatitis

In some cases, the immune system mistakenly attacks the liver, leading to inflammation and rapid liver failure.

Wilson’s Disease

This rare genetic disorder causes the accumulation of copper in the liver, leading to acute liver failure if left untreated.

Budd-Chiari Syndrome

This condition occurs when the blood flow out of the liver is obstructed, often due to blood clots in the liver’s veins.

Metabolic Disorders

Certain metabolic diseases, such as acute fatty liver of pregnancy, can trigger acute liver failure during pregnancy as a result the child could also suffer from Jaundice right after birth.
