Will high blood sugar lead to diabetic nephropathy?

Diabetic nephropathy is a chronic microvascular complication of diabetes. This disease will not occur until diabetes develops to a certain stage. Diabetic nephropathy is relatively hidden in the early stage. Its main manifestation is increased foam in the urine. Urine examination can find an increase in the ratio of urine microalbumin to urine creatinine. At this time, the disease is usually reversible. On the contrary, if the disease is not effectively controlled at this stage, long-term continuous leakage of proteinuria will cause a decrease in plasma albumin levels, causing eyelid and lower limb edema, and then renal failure, or even uremia.

Diabetic patients should pay more attention to the following conditions:

1. Foam appears in the urine, and it increases intermittently or continuously over time;

2. Abnormal urine test, increased ratio of urine microprotein to urine creatinine;

3. Eyelid and lower limb edema occurs;

4. Increased serum creatinine and cystatin C. The first two are early warning indicators of diabetic nephropathy. Once they appear, you should go to a kidney specialist for treatment in time.
