Hepatitis B is not the most afraid of exercise, exercise for hepatitis B patients can enhance physical fitness, but it does not have the role of hepatitis B treatment. Hepatitis B is a contagious disease caused by hepatitis B virus infection, patients need to carry out quantitative testing of hepatitis B dna virus in a timely manner, and need to carry out liver function and liver ultrasound examination. If the hepatitis B virus is significantly higher than normal and liver function is impaired, antiviral treatment with drugs such as tenofovir is needed, and liver-protecting drugs such as diammonium glycyrrhizinate need to be used in conjunction with the treatment; if the hepatitis B virus is within the normal range and there is no abnormality in the liver function, then regular monitoring is sufficient. Appropriate exercise can help enhance the body’s immunity, which is beneficial to the recovery of the disease, but exercise is not the same as treatment, and patients with more serious liver function damage are not suitable for exercise, so the statement that hepatitis B is most afraid of exercise is wrong. Hepatitis B is very harmful to the human body, patients need to go to the regular hospital in time to prevent further progress of the disease.
