What is the definition of chronic hepatitis B?

In general, chronic hepatitis B refers to chronic hepatitis B infection. The definition of chronic hepatitis B is a chronic disease caused by persistent infection with the hepatitis B virus for more than six months, leading to varying degrees of inflammation, necrosis, or fibrosis in the liver. Detailed analysis is as follows:

Chronic hepatitis B is primarily caused by infection with the hepatitis B virus. This virus can spread through blood, blood products, broken skin or mucous membranes, and sexual contact. Once infected, the virus replicates within the body and damages liver cells, causing liver inflammation and fibrosis, which may progress to chronic hepatitis B. Additionally, factors such as weakened immune function, genetic predisposition, long-term alcohol consumption, and co-infection with other viruses may also increase the risk of developing chronic hepatitis B. If not effectively controlled, chronic hepatitis B may lead to severe complications such as cirrhosis and liver cancer, significantly affecting the patient's long-term health.

The main symptoms of chronic hepatitis B include general fatigue, digestive disturbances, bleeding tendencies, jaundice, and pain or discomfort in the liver area. The presence of these symptoms is related to the extent of liver damage and individual differences. Some patients may not exhibit obvious symptoms and may only be found to have abnormal liver function during routine physical examinations.

Patients with chronic hepatitis B should follow a diet consisting of light, easily digestible, and nutritionally rich foods. They should avoid consuming excessive fatty, spicy, or irritating foods to prevent additional strain on the liver.
