nowadays, to TREAT Hep B, it is actually make the virus less active.
Therefore, for chronic carrier, if your liver function (e.g. ALT, AST, GGT, AFP) are normal, there are no need to take any medication. You only need to have a good balance on working / resting.
How do you know the Hep B virus are active?
of cause, you may feel more tired, and the liver enzyme go up. Your doctor may order a test for you called HBV-DNA. A high result in the test means the virus is active. By that time, medication is needed. and after treatment, your dr. may still order another HBV-DNA test for you and see if it goes down, i.e. less active.
so if you are a chronic carrier of Hep B, you better keep monitoring your liver enzyme.
