The patient’s urine protein is normal and the low blood creatinine is usually caused by the patient’s thin body size, low activity level, and low protein intake.
Creatinine is a product of creatine metabolism, which is mainly generated by the catabolism of the body’s muscles and the metabolism of proteins consumed in food. Low creatinine is associated with a thin body and less exercise.
People with small body size and less muscle content will have low blood creatinine due to less creatinine production; in addition, if the human body’s recent activity is less, muscle metabolism and creatinine production is also less, there will also be low blood creatinine phenomenon; furthermore, if the human body has recently consumed less protein, the creatinine production will be partial, and there will be low blood creatinine phenomenon.
Patients with normal urine protein and lower than normal blood creatinine should go to the hospital in time for treatment under the guidance of a professional physician.
