Whether Diabetes Can Damage My Kidneys or Not
The damage course of diabetes on kidneys
Diabetic kidney disease takes many years to develop. In the first few years of their diabetes, in some people, the filtering function of the kidneys is actually higher than normal.
Over several years, people who are developing kidney disease will have small amounts of the blood protein albumin begin to leak into their urine. This first stage of CKD is called microalbuminuria. The kidney's filtration function usually remains normal during this period.
As the disease progresses, more albumin leaks into the urine. This stage may be called macroalbuminuria or proteinuria. As the amount of albumin in the urine increases, the kidneys' filtering function usually begins to drop. The body retains various wastes as filtration falls. As kidney damage develops, blood pressure often rises as well.
The onset of kidney damage is always latent. Once diabetics present symptoms like edema, proteinuria, high blood pressure etc. that means the kidney damage has developed into middle or late stage, while at this stage, it will get harder to treat it. Actually, once diabetes happens, the kidney damage may already starts. Thereby, patients with diabetes should regularly check microalbuminuria in the urine to evaluate the kidney function.
Then how can I protect my kidney:
People with diabetes should
1. Check HbA1C level at least twice a year. The test provides a weighted average of blood glucose level for the previous 3 months. They should aim to keep it at less than 7%.
2. Follow the doctor's suggestions regarding insulin injections, medicines, meal planning, physical activity, and blood glucose monitoring.
3. Measure the amount of protein in the urine at least once a year to check for kidney damage.
4. Measure eGFR at least once a year to learn how well the kidneys are working.
5. Control the blood sugar under the normal range, and have a well planed diet plan.
