The liver is one of the most important digestive organs in the body, but liver lesions are often overlooked in their early stages. Because many people do not understand how hepatitis is contracted and how it is diagnosed and treated, there are many misconceptions about diagnosis and treatment. Timely checkups are very important for the prevention and treatment of hepatitis. Normal people should have regular medical checkups for early detection of liver lesions, and patients with liver disease should actively do regular follow-up examinations to prevent recurrence of liver disease. The onset of viral hepatitis is very insidious and most patients have mild or no symptoms and need regular medical checkups to detect the condition. For patients with viral liver disease, the first and foremost examination is biochemical and virological, and the routine tests include hepatitis B five, hepatitis C antibody test, liver function, kidney function, blood sugar, blood lipids, cholinesterase. Those who have liver function tests should avoid drinking alcohol at dinner the day before and not eat after 9 p.m. No breakfast or water on the day of the test, and blood should be taken on an empty stomach. Patients with liver disease should have regular checkups, but some people have problems with no, few or missed tests, which prevents doctors from accurately determining changes in the patient’s condition. In terms of treatment, some patients do not think they need treatment if they have no symptoms of hepatitis B because they do not have enough awareness. In the case of small triplets with normal liver function, for example, many patients and even doctors believe that no treatment is needed. However, clinical findings show that some patients with small triplets have normal liver function but the virus is still replicating, which can aggravate liver damage if left untreated. Only standardized treatment and persistent follow-up can achieve satisfactory results. Some patients blindly treat their disease, and seek medical help in an emergency or abuse prescriptions, which not only cannot reduce the lesions, but also may cause serious liver damage. Blind medication or neglected treatment may accelerate the trilogy of liver disease development: hepatitis, cirrhosis and liver cancer. Only through expert diagnosis, formulation of targeted standardized treatment plan and follow-up monitoring, patients can obtain satisfactory clinical results.
