Creatinine, including blood creatinine and urine creatinine, is an important indicator to evaluate kidney function and is important for the diagnosis of kidney disease. If the patient has a little low creatinine value and other indicators are normal, generally there is no big problem and no need for treatment, it is recommended to just review the creatinine value regularly. Creatinine is usually produced by the metabolism of proteins in the human body, so people with malnutrition, older age, wasting, etc., have lower creatinine than others due to lower protein intake, which is a normal physiological phenomenon, and if it is not accompanied by other abnormal test values or symptoms, there is usually no problem and no other special treatment is needed. Besides, some diseases such as anemia, nephritis, muscular dystrophy, leukemia, etc., may also have low creatinine due to their effects on metabolism or kidney function, and this is when there are some health problems. However, low creatinine cannot be used as an indicator to diagnose these diseases, and a comprehensive analysis is needed based on other symptoms and laboratory indicators, such as whether there are symptoms such as pallor, reduced urine output, weakness of limbs, easy bleeding, and whether other indicators of blood and urine routines are normal. It is recommended to check the creatinine value after a period of time. If there is no obvious change in the value, there is no need to worry too much, as the value may be slightly low due to your own constitution. If the creatinine is significantly low or the value changes significantly, it may be caused by other kidney diseases. It is recommended to cooperate with other examinations to clarify the cause and treat the symptoms.
