At present, there is no evidence to prove to what extent high blood glucose can harm the liver and kidneys. Clinical evidence suggests that when diabetes is severe, it may have a certain impact on liver and kidney function, resulting in damage to liver cells as well as kidney function, especially in diabetic patients whose metabolic function has already been disturbed. If the diabetes condition continues to develop, the examination will show that the urine protein is increased, and there may also be red blood cells, indicating that the kidney function has been impaired. When diabetes affects the liver, jaundice may be induced, and high bilirubin and other markers may be detected in the examination. It is impossible to tell exactly how high blood glucose affects the liver and kidneys, but it depends on the individual’s condition and the effect of blood glucose control. It is recommended that people with high blood sugar need to cooperate with the doctor to control their condition with reasonable medication, and consult the doctor promptly if they feel unwell.
