It is reported that there are more than 100 million hepatitis B patients in China. The biggest harm of hepatitis B is that the virus continues to infect and replicate, so that the patient’s liver function is constantly impaired, coupled with modern people often work late, run around, lose temper and alcohol abuse, more likely to make the liver fibrosis lesions or malignant changes. Among the patients with malignant changes, most of them have formed cirrhosis or liver ascites from hepatitis B and eventually transformed into liver cancer, while a few of them have developed into liver cancer directly from hepatitis B. The main reason for this is that the patients did not carry out or adhere to the regular treatment for hepatitis B. Since there is no clinical manifestation of malignant transformation in the early stage, many patients are found to have advanced liver cancer. Hepatitis should be treated to prevent malignant change: 1. Those who have symptoms. For example, those with frequent pain in liver area, weakness of limbs and yellowing of eyes, urine and skin, all suggest heavy symptoms; 2. Those with abnormal liver function. That is, the glutamic aminotransferase and glutamic oxalacetic aminotransferase two indicators are more than 40 units; 3, the DNA is positive. This means that there are more than 500 hepatitis B viruses in the body and the virus is constantly replicating; 4. Patients with major triplets. Even if the liver function is normal, the patient must be treated, otherwise the liver function will eventually be damaged as the number of viruses increases. In addition, children and adolescents who develop chronic hepatitis due to vertical transmission must also be treated if their liver function is not normal. In this case, it is important not to let the drugs be used for fear of their toxic side effects. At present, drugs such as lamivudine are more effective in DNA conversion, major triplet to minor triplet and restoration of liver function, and the side effects are relatively small, so patients can choose at their discretion. The hepatitis patients to carry out self-care: 1, careful use of liver-damaging drugs Some drugs directly metabolized by the kidneys is still good, but the need to metabolize drugs through the liver must pay more attention, especially do not blindly take some drugs to improve immunity. 2, less alcohol or no alcohol All drinks containing alcohol should not be consumed. After drinking alcohol about 90% of the alcohol component (ethanol) in the liver metabolism, the toxicity of ethanol will make liver cells degenerate necrosis. In particular, some chronic hepatitis B virus carriers, because the clinical symptoms are not obvious easy to indulge themselves and alcohol, thus increasing the risk of liver malignancy. 3.Diet and nutrition and exercise Balanced nutrition, adequate sleep, moderate exercise and optimism are the keys to prevent liver cancer in hepatitis patients. Avoid spicy diet, otherwise it is easy to make liver and gallbladder wet and hot, which will aggravate the disease; keep enough sleep to avoid mutation when cell division; do some sports activities appropriately to enhance the resistance of the body. Please note that depression, anger and other bad emotions hurt the liver and cause cancer. Doing the above is beneficial to the recovery of liver disease and avoid malignant changes of the liver.
