Cirrhosis is staged in two main ways: by the amount of scarring in the liver (fibrosis stages F0 through F4) and by how well the liver still functions (compensated versus decompensated). Understanding where you fall on each scale gives a clearer picture of what’s happening inside the liver, what symptoms to expect, and what the outlook looks like.
Fibrosis Stages: F0 Through F4
Doctors use a scoring system called METAVIR to grade liver scarring on a scale from F0 to F4. These stages are typically determined through a liver biopsy or a non-invasive scan that measures liver stiffness.
- F0: No scarring at all. The liver is healthy.
- F1: Mild scarring is present, but the overall liver structure is mostly preserved. The liver still works normally.
- F2: Moderate scarring has begun. Scar tissue is starting to build up but hasn’t disrupted the liver’s architecture in a major way.
- F3: Advanced scarring that affects larger areas of the liver and begins to disrupt blood flow through the organ.
- F4: Cirrhosis. Extensive scarring has caused lasting structural damage.
Stages F1 through F3 are considered fibrosis, not cirrhosis. The distinction matters because fibrosis at earlier stages is more readily reversible if the underlying cause (alcohol use, hepatitis, fatty liver disease) is treated. Once the liver reaches F4, the damage is far more severe, though even some cirrhosis can partially reverse under the right conditions.
How Liver Stiffness Is Measured
A common non-invasive tool called FibroScan sends a small vibration through the liver and measures how stiff the tissue is, reported in kilopascals (kPa). The stiffer the liver, the more scarring it has. The exact cutoffs for cirrhosis (F4) depend on the underlying liver disease:
- Alcohol-related liver disease: 19 kPa or higher
- Non-alcoholic fatty liver disease: 14 kPa or higher
- Hepatitis C: 14 kPa or higher
- Hepatitis B: 12 kPa or higher
A healthy liver with no significant scarring typically measures between 2 and 7 kPa regardless of the underlying condition. These ranges are estimates rather than hard boundaries, and your doctor will interpret them alongside blood work and imaging.
Compensated Versus Decompensated Cirrhosis
Once someone has cirrhosis (F4), the next critical question is whether the liver is still keeping up with its workload. This divides cirrhosis into two clinical stages that carry very different outlooks.
Compensated cirrhosis means the liver is scarred but still functioning well enough to handle its essential jobs: filtering toxins, producing proteins, and managing blood clotting. People in this stage have no major complications. Many feel relatively normal, and some don’t know they have cirrhosis at all. The median survival for compensated cirrhosis is more than 12 years.
Decompensated cirrhosis means the liver can no longer keep up. It’s defined by the appearance of one or more serious complications: fluid buildup in the abdomen (ascites), yellowing of the skin and eyes (jaundice), bleeding from swollen veins in the esophagus or stomach (variceal hemorrhage), or confusion and cognitive changes caused by toxin buildup in the brain (hepatic encephalopathy). Median survival drops to roughly 2 years once decompensation occurs. This is the stage where liver transplant evaluation typically becomes urgent.
Early Symptoms of Cirrhosis
In the earliest phase of cirrhosis, you may have no symptoms at all. The liver has significant reserve capacity, and symptoms often don’t appear until the damage is extensive. When early signs do show up, they tend to be vague enough that people attribute them to other causes: fatigue, skin itching, poor appetite, unexplained weight loss, nausea, mild discomfort in the upper right abdomen, and muscle cramps or weakness. Sexual problems and muscle loss are also common early signs.
Because these symptoms overlap with so many other conditions, cirrhosis is frequently caught through routine blood work or imaging ordered for unrelated reasons. By the time more obvious signs like jaundice or abdominal swelling appear, the disease has usually progressed to decompensation.
Child-Pugh Classification: A, B, and C
Doctors further classify the severity of cirrhosis using the Child-Pugh system, which assigns a score based on five factors: the presence and severity of fluid buildup, the degree of confusion from toxin accumulation, and three blood test results that reflect how well the liver is producing proteins and processing waste. The total score places patients into one of three classes.
Class A (mildest) carries a one-year survival rate close to 100% and a five-year survival around 64%. These patients generally have compensated cirrhosis with good liver function.
Class B (moderate) has a one-year survival of about 80% and a five-year survival between 60% and 75%. Liver function is noticeably impaired, and some complications may be present but manageable.
Class C (most severe) has a one-year survival around 45% and a five-year survival between 34% and 50%. These patients typically have decompensated cirrhosis with significant complications. Class C is a strong indicator that transplant evaluation should be underway.
MELD Score and Transplant Priority
When cirrhosis is severe enough that transplant becomes a possibility, the MELD score determines your place on the waiting list. The current version, called MELD 3.0, uses blood levels of bilirubin (a waste product), creatinine (a marker of kidney function), sodium, a blood clotting measurement called INR, and albumin (a protein the liver makes). It also accounts for sex, since earlier versions of the score systematically underestimated severity in women.
Higher MELD scores indicate more urgent need. The score is recalculated regularly, so your position on the transplant list can change as your condition changes.
Can Cirrhosis Be Reversed?
For a long time, cirrhosis was considered permanent. That view has shifted. In a study of 113 patients with biopsy-confirmed cirrhosis, about 12% showed verified reversal of their scarring, dropping by two or more points on the fibrosis scale. Among those whose cirrhosis reversed, the average fibrosis score fell from 4 (full cirrhosis) to 1.7 (closer to mild scarring). Blood markers of liver function, including platelet counts and albumin levels, also normalized in several patients.
The key factor was sustained suppression of whatever was damaging the liver in the first place. In patients with viral hepatitis, successful antiviral treatment drove the reversal. In those with autoimmune liver disease, effective immune-suppressing therapy did the same. Reversal is not guaranteed, and it’s far more likely in earlier cirrhosis than in advanced decompensated disease. But the evidence is clear that the liver retains some capacity to remodel even after reaching F4, provided the ongoing injury stops.
For people with alcohol-related cirrhosis, complete and permanent alcohol cessation is the single most important factor. For those with fatty liver disease, sustained weight loss of 7% to 10% of body weight has been shown to reduce fibrosis. Regardless of the cause, removing the source of injury gives the liver its best chance at partial recovery and, at minimum, can prevent progression from compensated to decompensated disease.
