Therefore, we must attach great importance to the choice of the initial treatment strategy. Because most of them at their own expense, and the best choice for the overall disease burden is relatively light drugs. Conditions permit, shall be noted at the outset, "Prevention of drug-resistant", select the drop-virus capability, a lower incidence of resistance to the high cost of antiviral drugs such as entecavir and so on, to avoid additional financial and time costs.

Expert view: the most commonly used for treating hepatitis B is a nucleoside analogue antiviral drugs, national hepatitis B treatment guidelines to curb or eliminate the hepatitis B virus as a primary goal of chronic hepatitis B treatment. When there is viral replication to be inhibited, the virus load dropped below the detection limit in order to reduce the patient's infectious, delay and prevent disease progression. Not timely review and adjustment of drugs, drug resistance occurs when you can not be timely discovered that an expensive and ineffective treatment delays disease, should be condemned. Note should adhere to a 2-3 months follow-liver function, DNA, a B-reviewed every six months, there are not feeling well should be promptly reviewed.

First of all, when the body is chronically hungry, the body can not get enough oxidation enzymes, will be mobilized to other parts of the body to store fat and protein, and convert it into glucose. This "transit stop" process, so that a large number of fatty acids to the liver.
Secondly, if the needs of choline lipid metabolism, protein and insufficient intake of essential fatty acids can affect the liver, lipid metabolism, leading to a large number of deposition of fat in the liver to form the fatty liver.
Third, the diet will result in the body of sugar, fat, protein, minerals and fiber intake of less than. In this case, the body will produce compensatory, making sugar, protein and so on into fat accumulation to the liver.
Because There is no cure for hepatitis B and complete a one-time effects of drugs come out, hepatitis B treatment more difficult, their treatment is bound to be a long process of the "Battle of Marathon."
