Hepatitis B is an uninvited guest who always comes to us unannounced. Since it is here, we can only receive it openly. Most importantly, we need to find out the true nature of this uninvited guest and minimize the damage caused by its visit. What will the arrival of hepatitis B bring to us? 1, post-hepatitis cirrhosis Hepatitis cirrhosis is developed from viral hepatitis, and in China, the vast majority of patients with cirrhosis are of this type. Chronic hepatitis B is the culprit of cirrhosis, and current statistics show that cirrhosis caused by hepatitis B accounts for about 80% of the total number of patients with post-hepatitis cirrhosis. Why does viral hepatitis lead to cirrhosis? It turns out that in the human blood, there is a kind of cell involved in the body’s immune function, which is like a body guard that can fight with the enemy and defend our health. This cell can actively attack the hepatitis B virus that invades the liver cells. However, this attack is somewhat destructive and after the attack, although the hepatitis B virus is destroyed, the liver cells are also damaged. This is the same as the fish death. After the liver cells are destroyed, the fibrous tissue goes to fill the vacancies of the destroyed normal liver cells, and as time passes, the fibrous tissue inside the liver cells increases, making the liver harden, reducing the number of liver cells, shrinking the shape of the liver, and decreasing the function, forming cirrhosis. The main threat caused by cirrhosis to human body is that it produces a series of complications, which are often fatal, for example, primary peritonitis, upper gastrointestinal bleeding, hepatic encephalopathy, hepatorenal syndrome, etc. 2.Primary liver cancer China is a high incidence area of liver cancer, and most of them are related to chronic hepatitis B. Liver cancer is a disease with high malignancy, and although there are multiple methods to treat it, the survival rate is low. The presence of liver cancer can often be detected by fetoprotein, ultrasound, CT and MRI. 3.Chronic heavy hepatitis Chronic hepatitis B patients can cause heavy hepatitis under the induction of some adverse factors (such as overexertion, long-term alcohol abuse, re-infection with hepatitis A, C or E virus). Severe hepatitis is a manifestation of massive necrosis of liver cells, which is critical and has a high mortality rate, and must be treated promptly. In the early stage of severe hepatitis, jaundice deepens day by day and develops rapidly, and serum bilirubin rises by more than 1 mg daily. Patients show intolerable abdominal distension, facial and lower limb edema, and necrotic atrophy of the liver. Infection, peritonitis, gastrointestinal bleeding, and hepatic encephalopathy are often stimulated. In the later stages of severe hepatitis, kidney function impairment such as oliguria or anuria may also occur, which is medically known as hepatorenal syndrome. The development of hepatorenal syndrome portends a very poor prognosis and a high mortality rate. As the saying goes, if you know yourself, you will never lose a hundred battles. Although hepatitis B is an uninvited guest, we have to accept it openly because, accept it or not, its arrival has become a reality. The only way we can accept it, understand it, know it, and get along with it in the most scientific and reasonable way is to minimize our losses and continue to live a healthy life.
