What is hepatitis B? I believe there is no one who does not know. Hepatitis B, also known as viral hepatitis B, is an infectious disease caused by the hepatitis B virus, with liver function impairment as the main manifestation. It can manifest as a state of hepatitis B virus carrier or chronic hepatitis, or it can progress to cirrhosis or liver function loss. Its symptoms are weakness, fear of food, nausea, abdominal distension, pain in the liver area, spider nevus, etc. Hepatitis B can be classified as mild, moderate and severe. There is no doubt that hepatitis B needs to be treated. But to what extent does hepatitis B develop before treatment is needed? I believe that every hepatitis B patient is concerned about this issue. In principle, as long as the hepatitis B virus is present in the body, the patient needs to receive treatment. However, due to objective and subjective reasons, it is possible to choose the right time for treatment without affecting the deterioration of the disease. The choice of this timing is also extremely important. Generally, when a patient with hepatitis B has some obvious symptoms such as loss of appetite, aversion to grease, bloating and diarrhea, pain in the liver area, nausea and vomiting, loss of energy, yellowing of the face, yellowing of the eyes, yellowing of the urine, etc., he needs to be seen promptly. This is because the appearance of these symptoms indicates that the condition of hepatitis B, has begun to out deteriorate. Any further delay in treatment can be life-threatening. The treatment of hepatitis B needs to start from the following aspects: 1, is good antiviral treatment; 2, is the symptomatic treatment, if the transaminases are elevated, you need to lower the enzyme treatment; if the patient appears jaundice, to reduce jaundice treatment; 3, for the treatment of complications, if the patient appears liver ascites and other symptoms to diuretic, improve albumin. Patients also need to be observed promptly to prevent deterioration of the disease. If hepatitis B is treated properly, although it is said that it cannot be completely cured, it is possible to control the symptoms and not to continue to develop. The treatment of hepatitis B is a long-term process, which requires mental preparation. Currently, vaccination against hepatitis B is the most effective way to prevent hepatitis B virus infection.
