What is Hepatitis B? Hepatitis B is the abbreviation of “Hepatitis B”. Hepatitis B seems to be a well-known disease in our country, but to explain in detail what is hepatitis B, not to mention the ordinary people, many doctors who do not specialize in liver disease are afraid that they do not quite understand. Hepatitis, as the name suggests, is the inflammatory response of the liver, inflammatory response is very complex to explain from the pathology, simply put, mainly hepatocytes and their surrounding tissues, degeneration, necrosis, regeneration and the accompanying fibrosis and a series of very complex pathological reactions. The hepatic inflammatory response inevitably leads to destruction and changes in the function and structure of the liver. In the case of acute hepatitis, the patient may essentially recover as before through treatment, and may even go through the entire process without showing any symptoms. Unfortunately, the most common type of hepatitis B is chronic hepatitis, which lasts from six months to decades. Currently there are five known hepatitis viruses, according to the order of discovery, China named type A, type B, type C, type D, type E, other countries are mostly named type A, type B, type C, type D, type E, so the Chinese outside the country is often said “hepatitis B” or simply “Hepatitis B Hepatitis B” or simply “Hepatitis B”, and Hepatitis B is the same meaning. For hepatitis B, non-professionals often have a lot of misunderstandings or conceptual confusion, mainly in the following two cases: 1, hepatitis B is a lifelong cure, very scary? As mentioned above, hepatitis B is divided into acute and chronic, the course of the disease within 6 months for acute hepatitis, more than 6 months for chronic hepatitis. infants and young children under the age of 5 years infected with hepatitis B virus in the vast majority of the development of chronic infection, children or adults over the age of 5 years old infected with the majority of the acute process, can be cured. In addition, most of chronic hepatitis B can be controlled through correct treatment, and a small part of it can be cured. 2.All chronic hepatitis B virus infected people are hepatitis B? The human body can carry hepatitis B virus for life, but only when there is obvious inflammatory reaction in the liver, it is called “hepatitis B”. Chronic hepatitis B virus infected people can have no obvious inflammatory reaction in the liver for a long time or even for a lifetime, and the harm caused by hepatitis B virus to the human body is mainly due to the recurring inflammatory reaction in the liver.
