Stage 1: Hepatitis
Liver tissues become inflamed when you have hepatitis. Inflammation is the liver's reaction to harm or poison. It is an effort to get rid of infections and get the healing process going. An instantaneous and transient response such as acute hepatitis often achieves this. However, the inflammation also continues as long as the damage or poisoning. Hyperactive healing brought on by chronic hepatitis eventually leads to scarring (fibrosis).
Stage 2: Fibrosis
Fibrosis is the gradual hardening of the liver caused by the accumulation of narrow bands of scar tissue. Scar tissue decreases blood flow through the liver, limiting its availability to oxygen and nutrients. This is how your liver's vitality steadily decreases. However, some fibrosis can be reversed. Your liver cells can regenerate, and scarring can be reduced if the damage is slow enough to allow for recovery.
Stage 3: Cirrhosis
Cirrhosis is a condition that causes extensive and persistent scarring in the liver. This is the stage at which fibrosis is irreversible. When your liver's healthy cells are depleted, its tissues cannot renew. However, you can still reduce or stop the damage at this point. Cirrhosis will begin to impair liver function, but your body will try to compensate for the loss, so you may not notice at first.
Stage 4: Liver failure
Liver failure occurs when your liver can no longer operate properly to meet your body's needs. This is also known as "decompensated cirrhosis" since your body can no longer compensate for the losses. As liver functions begin to deteriorate, you will see the impacts throughout your body. Chronic liver failure develops gradually but is deadly without a liver transplant. You cannot live without a liver.
