Be aware of your family history. If you have a family history of renal failure, make sure that you get checked by you doctor to find out about your renal function or any existing risks for renal disease.
Check you blood pressure and make sure that you don’t suffer from high blood pressure. If you do, start medical therapy and monitor it closely. Follow a low salt and low protein diet. Drink plenty of fluids, about two liters in air conditioner and about four liters in the heat of the beach, BBQ, etc.
Avoid potential insults to the kidneys such as nonsteroidal anti-inflammatory drugs, antibiotics, penicillins, sulfa drugs, etc.
Have your physician check you for protein in the urine, especially if you find your urine to be foamy. If you should be found to have protein in the urine, make sure the total amount is quantified and the decision is made as to whether you may need a renal biopsy or not.
A history of renal stones or urinary tract infections should alert the patient about the need to monitor further the renal function. Lupus, sarcoidosis, rhematoid arthritis, gout, hepatitis B and C, are all diseases with potential secondary renal worsening implications. Malignant diseases such as colon cancer, lymphoma, renal cell cancer, and multiple myeloma are closely related to worsening of renal function. Your kidneys should be monitored closely should any of these factors be present.
