Uncontrolled blood sugar can cause kidney problems in diabetes (diabetic nephropathy).What makes it worse is that patients may remain unaware of the development, as in early stages the kidney disease does not produce any symptoms. Therefore, timely detection of kidney disease is imperative for it to be checked as early as possible.
According to National Kidney Foundation guidelines kidney disease can be detected earlier in diabetics as well as other high-risk cases (such as those having high blood pressure, or family history of diabetes or high blood pressure or chronic kidney disease) by performing 2 simple tests to check the blood creatinine levels and protein in urine.
It is advisable for diabetics to keep a check on their blood levels of creatinine. An increased creatinine (waste product excreted in urine) level in blood shows that the kidneys are damaged and hence not able to clear creatinine from the blood efficiently. At the same time even small amounts of protein in urine indicate early kidney damage. These tests not only help to detect early signs of kidney disease but also help in knowing whether your treatment is working effectively or not. Hence, by getting these investigations done religiously you can prevent or delay damage to your kidneys.
It is also important that diabetes patients keep their blood sugar levels within normal limits and take the prescribed medications regularly to prevent and check damage to the kidneys
