Dizziness in diabetic nephropathy may be caused by blood sugar causes such as hypoglycemia, hyperglycemia, hypertension, anemia or combined cerebrovascular disease. 1. Blood sugar causes: hypoglycemia or hyperglycemia can lead to dizziness, patients need to adjust the glucose-lowering program under the guidance of specialists. 2. Hypertension: Diabetic nephropathy patients with severe hypertension can cause brain discomfort and dizziness. 3. Anemia: The decline of renal function in patients with diabetic nephropathy will affect the secretion of erythropoietin, and patients may suffer from nephropathic anemia, which will also cause dizziness. 4. Combined cerebrovascular disease: Diabetic nephropathy patients are at increased risk of combined atherosclerotic disease, patients may suffer from cerebrovascular disease such as cerebral infarction, which affects the blood supply to the brain and causes dizziness. If diabetic nephropathy patients have symptoms of dizziness, it is recommended to go to regular hospitals as soon as possible for consultation and examination, to clarify the cause, and take timely treatment measures under the guidance of professional physicians, so as not to delay the condition.
