7 Tips to Safeguard Your Kidney Health

According to the National Kidney Foundation, one in three Americans are at risk of chronic kidney disease. What makes this statistic worrisome is most people don’t know their kidneys aren't working correctly until their symptoms are so advanced they need dialysis or a kidney transplant.

Making the right lifestyle choices to help prevent serious, life-threatening kidney problems is very important, especially as people get older, when the risks of kidney problems and developing kidney stones increase.

What Do Kidneys Do?

The kidneys are two, bean-shaped organs, each about the size of a fist, located just below the rib cage, one on each side of the spine.

In terms of your urinary system, the kidneys are a 24-hour powerhouse of activity. Every day, your two kidneys filter about 120 to 150 quarts of blood to produce about one to two quarts of urine, composed of wastes and extra fluid.

Otherwise healthy people can help keep their kidneys functioning at an optimal level by following these seven recommendations:

1. Drink up. To dilute urine and keep kidneys clear of toxins in the body, drink two liters of fluid a day – about 32 ounces. If someone has a history of kidney stones, we recommend drinking 2.5 liters – about 40 ounces – of water daily to reduce the risk of forming new stones. That’s because kidney stones are made of crystals that form together when their concentration is high. Drinking enough liquids dilutes the urine and prevents the aggregation of those crystals.
2. Shake the salt habit. Too much salt in your body makes your kidneys work extra hard to restore a balance of electrolytes and fluids. Consistently high salt levels damage your kidneys and impair long-term kidney function. The recommended daily salt intake is 1,500 to 2,000 mg of sodium – about one teaspoon – per day. So stay away from hidden salt mines found in deli meats, movie popcorn, frozen meals, fast foods and processed foods.
3. Limit over-the-counter meds. NSAIDs (non-steroidal anti-inflammatory drugs) like Ibuprofen, Aleve, Advil, Celebrex, Voltaren, Motrin IB and higher-dose aspirin don’t pose a serious danger if your kidneys are healthy and if they're only used once in a while. However, consistent, daily use of NSAIDs can cause kidney damage. Unless being medically supervised, it is recommended that people take the recommended dose of an anti-inflammatory drug for only about five consecutive days. After that, it’s time to check with a medical professional.
4. Monitor your blood pressure and sugar levels. High blood pressure and diabetes are two of the top causes of kidney damage. Experts recommend that if you have diabetes and hypertension, your kidney function should be regularly checked. If you are obese and have a family history of kidney disease, your kidney function should be checked routinely as well.
5. No smoking. Smoking can damage blood vessels and reduce the flow of blood to the kidneys, which prevents the kidneys from functioning properly. Smoking can also raise blood pressure and increase the risk of kidney cancer.
6. Exercise regularly. Staying physically fit helps keep your weight low and your blood pressure normal.
7. Eat a healthy diet. Fill your plate with plenty of fresh fruits and vegetables, lean meats, chicken, fish, nuts and whole grains. A nutritious diet will also keep your blood pressure and sugar levels in check.

To keep your kidneys healthy, you must keep your overall body healthy. Making good lifestyle choices, like eating a healthy diet, exercising, watching your weight and staying hydrated, are steps in the right direction.
