Question: My mum is a type 2 diabetic. A recent lab test shows creatinine 1.5 and BUN 11.2. How can we stop creatinine increasing? Any suggestion is appreciated.
Answer: Diabetes is a leading cause of Chronic Kidney Failure, or End Stage Renal Disease (ESRD). When it has caused kidney damage, the creatinine level is generally higher than the normal range (0.5-1.1mg/dL for female and 0.6-1.2mg/dL for male in adults). Creatinine 1.5 indicates that your mother’s kidneys are mildly damaged. At this time, she should pay attention what she eat and drink. Avoid foods containing much salt and protein, because they will burden the kidney and cause more excessive wastes including creatinine to deposit in the blood. As a result,, your mother may have some symptoms like swelling, high blood pressure or proteinuria. Secondly, as your mother is a diabetic, she should also keep her sugar level under control either by a restricted diet or medicines. As for medicines to lower your mother’s blood sugar level, I do not recommend the antidiabetic agents because there are many side effects have been shown, such as hypoglycemia and weight gain. She may as well try some Chinese herbal teas, which are good for reducing high blood sugar level as well as protecting the kidney function.
