Diabetes can be called the “root of all evil”, it will damage our blood vessels throughout the body, when the damage to the small blood vessels will appear diabetic retinopathy, diabetic nephropathy, and the current number of people suffering from diabetic nephropathy in China is very large, has been called the most important cause of kidney disease. If you have diabetes for more than 5 years, you should routinely check the fundus, urinary routine, creatinine, urea and other indicators to assess the condition. When diabetic retinopathy occurs, kidney damage often occurs at the same time. Diabetic nephropathy is divided into 5 stages, stage 1 shows increased glomerular filtration rate, stage 2 shows intermittent microproteinuria, stage 3 shows continuous microproteinuria, stage 4 shows massive proteinuria, stage 5 shows hyperalgesia, the key to treatment is early detection and early intervention, before diabetic nephropathy stage 3, you can control blood sugar strictly so that glycated hemoglobin does not exceed 7%, control blood pressure at Before diabetic nephropathy stage 3, we can control blood pressure below 130/80mmHg by strictly controlling blood sugar so that glycated hemoglobin does not exceed 7% and blood pressure is below 130/80mmHg. When the disease progresses to stage 4 and stage 5 of diabetic nephropathy, the above treatment can only delay the deterioration of kidney function, and will eventually progress to uremia, which requires regular dialysis treatment.
