“The liver is very afraid of infection, hepatitis B patients must pay attention to the prevention of colds in the winter”, cold medicines may aggravate liver damage, hepatitis B patients are best not to buy cold medicines at the drugstore on their own, even if the symptoms are not serious, but also try to find the attending doctor to prescribe drugs. At present, it is the season of colds, viruses, bacteria or other pathogens can easily attack the human body. Prof. Wang Qinhuan said that some toxins in these germs can directly aggravate liver lesions, so the infection itself will make hepatitis B lesions worse. Therefore, hepatitis B patients once a cold but no fever, do not necessarily have to take medication, can drink more water, more rest; if the cold is accompanied by fever, coughing yellow sputum, etc., indicating that the body may have a bacterial infection, need to go to the hospital to do blood tests, if the white blood cells are higher than the normal value, some anti-infective drugs are available. No matter which kind of medicine is used to treat a cold, the prescription for hepatitis B patients must be prescribed by a doctor. The patient can see either a hepatologist, an infectious disease department or a respiratory department. It is important to make sure that the doctor is aware of his or her history of hepatitis B, so that the doctor can choose the right medication that is less damaging to the liver. Whether you have a cold or other diseases that require medication, do not just stop taking anti-hepatitis B virus medication, which should be taken for a long period of time, and unauthorized stopping of medication can easily cause recurrence or aggravation of the hepatitis B condition. In addition, chronic hepatitis B patients have lower immunity, patients should exercise regularly and pay attention to keep warm. For those who have frequent colds, thymidine and other immunity-enhancing drugs can be used appropriately under the guidance of doctors.
