Vitamin B in general is less damaging to liver function, and for vitamins in general have positive implications for liver function. The liver needs a variety of vitamins in the synthesis of other substances, including vitamin K as well as vitamin B, and other vitamins, and the right amount of vitamin supplementation is beneficial for good liver liver function. For liver function, the patient needs to have blood drawn to check whether glutamate and glutamic oxalacetic transaminase are elevated. If glutamate and glutamic oxalacetic transaminase are elevated, consider the patient to have liver insufficiency and hepatocyte necrosis. If the bilirubin is elevated and the total bilirubin is above 34.2umol/L, the patient should be considered to have liver insufficiency and hepatocellular necrosis, and the cause of liver insufficiency should be further investigated. For example, whether the patient has viral hepatitis, whether the patient has autoimmune hepatitis, and whether the patient has been drinking alcohol and taking medication for a long time, all these conditions can cause liver function damage, and after finding the cause, actively treat the cause and moderate liver protection treatment.
