Creatinine is a waste product in your body. Normally, your kidneys filter creatinine out of your bloodstream. If you have high creatinine levels, this indicates a problem with your kidneys. Kidney function can become impaired from chronic kidney disease or acute kidney failure. If your diagnosis is acute kidney failure, you may be able to recover full kidney function. Chronic kidney failure requires ongoing treatment. To treat impaired kidney function, you'll have to treat the underlying cause of your kidney problems. Kidney function may diminish due to hypertension, diabetes and possibly high cholesterol.
Treat your high blood pressure, if this is the underlying condition causing your kidneys to function abnormally. You may need high blood pressure medication, such as an ACE inhibitor. Your doctor may also recommend a diuretic if your hypertension medication is not sufficient.
Control your diabetes. Diabetes can also cause kidney damage. If you've been unable to adequately control your blood sugar levels through a healthy diet and regular exercise, you may need to take diabetes medication or insulin.
Lower your LDL cholesterol. High cholesterol may also be a factor in decreased kidney function. You'll need to follow a strict, low-fat diet, along with a consistent exercise plan to lower your cholesterol. Your doctor may also recommend cholesterol-lowering medications.
Prepare for dialysis treatment. Dialysis is a process by which your blood is filtered through a machine. This removes toxins and other wastes from your body, because your kidneys are unable to function properly. Talk to your doctor about your dialysis options. You may be able to use dialysis in your home. Nocturnal dialysis filters your blood as you sleep. Or you may need to go to a dialysis centre three times a week for several hours.
Follow your doctor's recommended diet plan or work with a dietitian to develop an appropriate meal plan for you. Impaired kidney function means that you will be unable to eat large amounts of certain nutrients, such as protein. Including too much protein, sodium or potassium levels in your diet will be detrimental to your health, as your kidneys will be unable to filter them properly.
