First, let us understand the causes of cirrhosis. The most common cause is chronic hepatitis B, which can develop into hepatitis B-related cirrhosis over time. The second is chronic hepatitis C, which can also lead to hepatitis C and cirrhosis in the long term. Another type is alcoholic cirrhosis, which occurs due to long-term excessive alcohol consumption. Cirrhosis involves the hardening of the entire liver, not just parts of it; the whole organ becomes hardened, not just certain sections. Once the entire liver is hardened due to cirrhosis, it is not possible to just remove a part and expect a normal liver to grow back. Thus, unlike what might be suggested in some discussions, it is not feasible to remove a part of a cirrhotic liver with the expectation of regeneration. Liver cirrhosis cannot be partially removed; it is not operable in this way.

Can cirrhosis be detected by ultrasound B?

If there are signs of hardening in the liver, which we call cirrhosis, an ultrasound, specifically a hepatobiliary ultrasound, can detect it. Especially in the middle and late stages, cirrhosis has some characteristic features on an ultrasound. First, one can observe the size of the liver. By the middle and late stages, the liver usually shrinks—a slight enlargement may occur early on, but it generally progressively diminishes. Additionally, the texture of the liver becomes harder, and through the ultrasound, the texture appears uneven with a bumpy feeling, or in other words, there can be seen a diffuse and uneven echo. However, for early-stage cirrhosis, a standard ultrasound may not be as sensitive. Nowadays, there are digital liver ultrasounds specifically designed to measure the degree of liver hardness, which provide objective data to help diagnose more sensitively and objectively. This method can definitely detect the condition.

How long can one live with hepatitis B-related cirrhosis?

We cannot give a definite answer on how long a patient with hepatitis B-related cirrhosis can live, as the life expectancy in late-stage cirrhosis is influenced by many factors including treatment measures, lifestyle adjustments, daily healthcare, and physical condition. Patients in the compensated stage of cirrhosis, if treated and the progression of cirrhosis is halted, with normal liver function and negative hepatitis B virus replication indicators, can work normally. In this state, the quality of life is good, and they can live to 70 to 80 years old. For patients in the decompensated stage of cirrhosis, if untreated and the cirrhosis is allowed to progress, about 70 to 80% may die within 5 years; however, aggressive treatment, including traditional Chinese medicine for liver fibrosis and cirrhosis, combined with antiviral treatment, bleeding prevention, liver protection, and liver transplantation, can significantly increase the survival time of patients.

Is liver cirrhosis with ascites contagious?

Liver cirrhosis in the decompensated stage with ascites present is not inherently contagious. Whether the condition is infectious depends not on the severity of liver function, the degree of liver cirrhosis, or the gravity of ascites, but rather on the underlying cause of the liver cirrhosis. For example, liver cirrhosis caused by alcohol consumption is not contagious. However, if the liver cirrhosis is due to viral hepatitis, such as commonly seen with hepatitis B or C, the condition can be infectious. Therefore, the presence of ascites or liver cirrhosis itself is not an indicator of infectiousness; the crucial factor is whether there is an infectious virus present.

What foods are good for cirrhosis?

The usual diet plays a crucial role for patients with cirrhosis, and it has been confirmed that nutritional therapy is very important for reducing mortality and disability rates in patients with cirrhosis. Generally speaking, easily digestible, high-vitamin nutritional foods should be the main source of food, alcohol must be strictly prohibited, and consumption of vegetables and fruits should be increased. Salt intake can be controlled, and adjustments should be made according to different changes in the condition. Another point to note is that patients with esophageal and gastric varices must avoid consuming hard and rough food, as this could lead to rupture of the varices and cause severe bleeding.

Do you need a liver transplant in the early stages of cirrhosis?

In the early stages of cirrhosis, liver transplant is not necessary. Early-stage cirrhosis requires timely and comprehensive auxiliary examinations to determine the cause of the cirrhosis. This includes determining whether it is due to viral hepatitis, cholestatic hepatitis, or drug-induced hepatitis, among others. Once a patient exhibits early signs of cirrhosis, it is crucial to treat the specific cause and symptoms actively, and undertake proactive liver protection treatments. It is also essential to prevent complications associated with cirrhosis, such as esophageal and gastric variceal bleeding, primary liver cancer, hepatorenal syndrome, liver disease, and ascites.
