It is vital for patients to do the right thing to protect their kidney no matter how advanced their kidney disease is. Doing something precaution in the early stage of CKD may help you avoid painful and expensive measures like dialysis. Here are some measures that can help preserve residual renal function.

A regular exercise will help you control your blood pressure and your body weight; if you have diabetes, exercise will also help you manage it. You don’t need to join a gym. Walking can be excellent, low-impact exercise.

The most effective drugs are Angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs). Aside from reducing blood pressure, ACEIs and ARBs prevent protein loss in urine and consequently swelling of the body. These drugs can also be prescribed for diabetes-induced renal disease.
