I suggest that you monitor your blood pressure and make sure the blood pressure is less than 130/80. I suggest that you eat a low salt healthy diet. I am an advocate for the DASH diet and you can review the DASH diet at: https://www.nhlbi.nih.gov/health/health-topics/topics/dash
I suggest that you maintain a healthy life style and healthy body weight. You should not smoke and not drink alcohol to excess. You should continue to exercise and increase your physical activity. If you are body building, you should not lift excessive weight and avoid power lifting.
You should avoid using non-steroidal anti-inflammatory drugs (NSAID’s) such as ibuprofen and naproxen for pain.
If you do all these things, these are the actions you can take to keep your kidneys healthy.
