The normal reference value of urinary creatinine is 7~18mol/d (800~2000mg/d) for men and 5.3~16mol/d (600~1800mg/d) for women. So urine creatinine 300mg/d belongs to the abnormal situation may be related to physiological phenomenon, renal insufficiency, anemia and so on.
1. Physiological phenomenon: low urinary creatinine can be seen in the dietary disorders of the population, part of the population diet is relatively light, eat less meat, resulting in insufficient protein intake, thus lowering urinary creatinine. The thin and weak people can also have a decrease in urinary creatinine, do not need special treatment, should increase the intake of high-quality protein, optional review.
2. Renal insufficiency: including acute and chronic renal insufficiency, affected by the reduction of glomerular filtration rate, there will be a decrease in blood creatinine excretion, resulting in increased blood creatinine, which leads to low urinary creatinine level.
3. Anemia: As anemia is a chronic wasting disease, it can lead to poor physical condition and insufficient protein in the body, causing low urine creatinine.
Low urinary creatinine can also be seen in other reasons, it is recommended to consult a doctor in time, follow the doctor’s instructions to carry out relevant examinations, with the help of the doctor to clarify the cause, and targeted treatment or treatment.
