Liver Failure — A Medical Emergency

When the liver can no longer perform its essential functions, life is at risk. Liver failure — acute or chronic — requires immediate specialist evaluation and may require a liver transplant. Know the signs.

What Is Liver Failure?

Liver failure is a life-threatening condition in which the liver loses its ability to perform vital functions — detoxifying the blood, synthesising proteins (including clotting factors), regulating blood sugar, producing bile, and processing nutrients. When these functions fail, every organ system in the body is affected.

Liver failure is not a single condition. It has three distinct clinical presentations with different timelines, causes, and treatments:

Acute Liver Failure (ALF)

Rapid collapse of liver function in a previously healthy person. Develops within days to weeks. Medical emergency.

Acute-on-Chronic Liver Failure (ACLF)

Sudden severe decompensation in a patient with known chronic liver disease, often triggered by infection or bleeding.

Chronic Liver Failure (Decompensated Cirrhosis)

Gradual failure over years as cirrhosis progresses. Complications accumulate.

Causes of Liver Failure

Acute Liver Failure (most common causes in India)

  • Viral hepatitis: Hepatitis E is the leading cause of acute liver failure in pregnant women; Hepatitis A and B cause severe acute hepatitis in susceptible individuals
  • Drug-induced liver injury (DILI): Paracetamol (acetaminophen) overdose; herbal remedies, ayurvedic preparations, and unregulated supplements are increasingly implicated
  • Alcohol: Acute alcoholic hepatitis superimposed on cirrhosis
  • Wilson's disease: Copper overload — can present dramatically as acute liver failure in young patients
  • Autoimmune hepatitis
  • Budd-Chiari syndrome: Hepatic vein thrombosis

Chronic Liver Failure (Decompensated Cirrhosis)

Any cause of chronic liver disease that progresses to cirrhosis can lead to decompensation — alcohol, Hepatitis B/C, MASLD, autoimmune, cholestatic diseases. Triggers for decompensation include gastrointestinal bleeding, infection, medications, surgery, or alcohol.

Emergency Warning Signs — When to Call Immediately

Go to Emergency or Call +91 88846 94233 if you notice:

  • Sudden confusion, disorientation, or inability to wake up (hepatic encephalopathy)
  • Vomiting large amounts of blood (variceal haemorrhage)
  • Rapidly worsening jaundice over hours to days
  • Severe abdominal swelling with pain and fever (spontaneous bacterial peritonitis)
  • Dramatic drop in urine output (hepatorenal syndrome)
  • Unexplained bruising and spontaneous bleeding

Do not drive yourself — call an ambulance or family member immediately.

Understanding the MELD Score

The MELD Score (Model for End-Stage Liver Disease) is the standard tool to measure how severe liver failure is and to prioritise patients on the transplant waitlist. It is calculated from three blood tests: creatinine (kidney function), bilirubin, and INR (clotting).

What Your MELD Score Means

<10 Low severity. Medical management. No immediate transplant indication.
10–15 Moderate. Begin transplant evaluation and listing discussions.
15–25 High. Transplant strongly recommended. Active listing warranted.
>25 Severe. High 90-day mortality without transplant. Urgent evaluation.

Treatment of Liver Failure

ICU / Medical Management (Bridge Therapy)

  • Lactulose and rifaximin for hepatic encephalopathy
  • N-Acetyl Cysteine (NAC) for paracetamol-induced acute liver failure
  • Antibiotics for spontaneous bacterial peritonitis
  • Terlipressin + albumin for hepatorenal syndrome
  • Coagulopathy management (FFP, vitamin K, platelets)
  • Nutritional support (high calorie, controlled protein)
  • Paracentesis for tense ascites
  • Endoscopic band ligation for variceal bleeding; Sengstaken tube as emergency temporising measure

Liver Transplantation — The Only Cure

For irreversible acute liver failure meeting King's College Criteria, and for decompensated chronic liver failure with MELD >15, liver transplantation is the only definitive treatment.

Dr. Srinivas Bojanapu performs both Living Donor Liver Transplant (LDLT) and Deceased Donor Liver Transplant (DDLT) at Kauvery Hospital, Electronic City. In urgent cases, the living donor pathway can be completed in 5–7 days from evaluation to surgery.

Frequently Asked Questions — Liver Failure

How quickly does liver failure progress?
Acute liver failure can progress from jaundice to coma within days. Acute-on-Chronic Liver Failure (ACLF) has a 28-day mortality of 30–50% without intervention. Chronic liver failure (decompensated cirrhosis) may progress over months to years. All forms require urgent specialist review.
Can the liver repair itself in liver failure?
The liver has remarkable regenerative capacity. If the cause of acute liver failure is removed early (e.g., stopping a hepatotoxic drug, treating Hepatitis E), the liver can recover fully in some cases. However, once decompensated cirrhosis develops, the structural damage is permanent and cannot be reversed without transplantation.
What happens in the last stages of liver failure?
Advanced liver failure leads to: severe jaundice, coagulopathy (uncontrolled bleeding), renal failure (hepatorenal syndrome), encephalopathy (confusion and coma), severe infection, and ultimately multi-organ failure. Without transplantation, end-stage liver failure is fatal. Identifying and listing patients before this stage is critical.
Is there a dialysis equivalent for the liver?
MARS (Molecular Adsorbent Recirculating System) and SPAD are liver support systems used as a bridge to transplant or to buy time for the liver to recover in acute liver failure. They are not a substitute for transplantation and are available only in select centres. They do not replace liver function long-term.
