Disease description:

I went for a medical check-up at my workplace a few days ago and found that my blood creatinine level was low, while other kidney function indicators were within the normal range. I would like to ask what might cause a low blood creatinine level?

Low blood creatinine levels can be mainly attributed to disease-related factors and non-disease-related factors. 1. Regarding disease-related factors, conditions such as anemia, malnutrition, muscle atrophy, leukemia, and diabetes insipidus may lead to abnormal muscle metabolism or impaired kidney function, thereby affecting the normal production and excretion of blood creatinine, resulting in lower levels. 2. Concerning non-disease-related factors, specific populations such as the elderly, underweight individuals, and pregnant women may have relatively lower muscle mass or higher glomerular filtration rates, which are physiological characteristics that can also result in low blood creatinine levels. 3. Individual variations, dietary habits, and other factors may also influence blood creatinine levels to some extent. Low blood creatinine itself may not have direct clinical significance and should be comprehensively analyzed in conjunction with the patient's specific condition. If concerns persist, timely medical consultation is recommended.
