Normal values for blood creatinine range from 53 to 106 μmol/L for men and 44 to 97 μmol/L for women, and may vary slightly from hospital to hospital. A blood creatinine of 102 μmol/L is either normal or mildly elevated. If it is normal, no treatment is needed. If it is mildly elevated, it can be improved by general treatment such as dietary modification and medication. 1. General treatment: Mildly elevated creatinine can be caused by physiological factors such as short-term consumption of large amounts of protein, strenuous exercise, etc. It can be controlled by adjusting the dietary structure, eating vitamin-rich foods, controlling the intake of salt and protein, and at the same time, paying attention to rest and avoiding physical exertion. 2. Drug therapy: creatinine mild increase can be seen in acute and chronic renal disease, at this time should be further examined to clarify the cause of the disease, commonly used drugs are medicinal charcoal tablets, Haikun kidney capsule to lower creatinine. Commonly used drugs for primary disease include hormones such as methylprednisolone, immunosuppressants such as tacrolimus, and so on. Blood creatinine 102μmol/L is in the normal range or mildly elevated, but the sensitivity of a single indicator is not high, and the judgment of renal function needs to be analyzed in conjunction with the patient’s gender, body weight, age, medical history, and glomerular filtration rate and other laboratory tests. If the blood creatinine continues to increase, or even the clinical manifestation of kidney damage occurs, you should go to the hospital in time, and under the guidance of the doctor to identify the cause and give targeted treatment to avoid aggravation of the condition.
