Final answer:
Regular exercise (C) can help counter diabetic nephropathy by managing blood sugar levels and improving kidney function. High blood pressure and a high protein diet can worsen kidney damage, whereas maintaining a healthy blood sugar balance and reducing sodium intake are essential in managing the condition.
Step-by-step explanation:
Among the options provided to counter diabetic nephropathy, regular exercise (C) can be beneficial in managing this condition. Diabetic nephropathy is a serious complication of diabetes mellitus characterized by damage to the capillaries in the kidneys' glomeruli. This condition can lead to albumin being excreted in the urine, which is a common indicator of nephropathy. While high blood pressure (A) and a high protein diet (D) can potentially exacerbate kidney damage, regular exercise can help to control blood sugar levels and improve overall kidney function.
Moreover, managing diabetes by keeping blood glucose levels within a target range can help prevent further kidney damage. Reducing sodium intake is also crucial in managing diabetic nephropathy. It's important to note, however, that a low blood sugar level (B) is not something we aim for as a treatment; rather, we strive to maintain a healthy blood sugar balance. Medications may also be prescribed to reduce high blood pressure and protein levels in the urine.
