The treatment of diabetic nephropathy also depends on the specific stage the patient is in. During stages one to three, the main clinical treatments include controlling blood sugar, blood pressure, and lipids. Patients with diabetes often also have these metabolic disorders, including hypertension and hyperlipidemia, which can damage the kidneys. In addition, in the early stages, some medications are often chosen to reduce the pressure on the glomeruli. For example, using ACE inhibitors or angiotensin receptor blockers (ARBs) and inhibitors of the sodium-glucose cotransporter, these drugs can also slow the progression of kidney failure. However, if the patient's condition has progressed to stage five, which is essentially equivalent to the state of uremia, the patient will then need dialysis treatment.

Is stage three diabetic nephropathy severe?

Stage three of diabetic nephropathy refers to patients who have persistent microalbuminuria, indicating a relatively mild state of the disease at this time. In fact, diabetic nephropathy is divided into five stages. During the first and second stages, patients generally do not exhibit specific symptoms clinically and may even test negative for proteinuria; however, an increase in kidney size and glomerular filtration rate may occur. By the third stage, patients begin to exhibit small or micro amounts of urinary albumin. The pathological damage to the kidneys at this stage is not considered particularly severe. Patients may experience hyalinization of small arteries and nodular lesions in the glomeruli. Within the staging of diabetic nephropathy, this does not constitute a particularly severe phase; however, the condition of the patients may continue to progress, leading to significant proteinuria and even renal failure.

How to supplement for anemia in diabetic nephropathy?

Patients with diabetic nephropathy who exhibit anemia are often in a state of chronic renal failure. This anemia caused by chronic kidney disease is mainly due to the decreased secretion of erythropoietin by the kidneys. Therefore, treatment involves the use of erythropoietin to stimulate bone marrow hematopoiesis. In addition to this medication, patients generally also need to supplement with iron preparations, such as ferrous succinate, sucrose iron, etc., and take oral folic acid, all of which are raw materials for blood formation. Furthermore, if patients have severe malnutrition, they should also supplement with foods rich in protein, such as eggs, milk, chicken, duck, fish, etc. (Please use medications under the guidance of a doctor.)

Does diabetic nephropathy hurt?

Diabetic nephropathy generally does not cause painful symptoms. Diabetic nephropathy refers to the kidney damage that results from long-term diabetes, caused by factors such as hyperglycemia, oxidative stress, and an increase in advanced glycation end products. In the early stages, patients may experience an increase in kidney size and an increased glomerular filtration rate. As the condition progresses, proteinuria may occur, and it could eventually lead to severe renal failure. Throughout this process, patients typically do not experience pain because the kidneys do not have nerve innervation and therefore do not feel pain. Thus, including diabetic nephropathy, various kidney diseases and nephritis generally do not manifest with pain.

How to check for diabetic nephropathy?

For the examination of diabetic nephropathy, patients first need to undergo routine urinalysis and check for the urinary albumin excretion rate. Generally speaking, one characteristic of diabetic nephropathy is the presence of urinary protein. A urinary albumin excretion rate between 20 and 200 µg/min is an important basis for diagnosing early diabetic nephropathy. If a patient’s urinary albumin excretion rate consistently exceeds 200 µg/min, significant diabetic nephropathy is often considered. Of course, this is under the assumption that the patient has had diabetes for at least ten years and has diabetic retinopathy. A kidney biopsy is needed for confirmation. Of course, to assess the impact of diabetic nephropathy on kidney function, blood tests for serum creatinine and urea nitrogen are necessary.
