An estimated 37 million U.S. adults have chronic kidney disease, or CKD, and millions more are at increased risk, according to the National Kidney Foundation. Early detection can help prevent the progression of kidney disease to kidney failure.
Troubling hallmarks of the American lifestyle, which include high consumption of processed and sugary foods, low physical activity levels and chronic sleep deprivation, are fueling an increased prevalence of high blood pressure, metabolic syndrome and diabetes. And these risk factors can contribute to chronic kidney disease.
The two main causes of CKD are diabetes and high blood pressure, which are responsible for up to two-thirds of U.S. cases. About 1 of 3 adults with diabetes and 1 of 5 adults with high blood pressure may have CKD, according to the U.S. Centers for Disease Control and Prevention (CDC).
“It is vital that you control these two conditions and their effect on your kidneys by seeing your doctor regularly, monitoring your blood pressure, eating a healthy diet, reducing salt intake and taking any medications as prescribed,” says Gabriel Solti Grasz, M.D., an internal medicine physician with Baptist Health Primary Care.
National Kidney Month March is National Kidney Month, and Thursday, March 11th, is recognized as World Kidney Day. Both observances involve campaigns to educate the public on the importance of reducing the frequency and impact of kidney disease.
The kidneys function as the body’s filtration system. But when they don’t work properly, the body may struggle to eliminate fluid and waste. In extreme cases, chronic kidney disease, or CKD, can lead to the need for dialysis or a kidney transplant over time.
If you are at increased risk for chronic kidney disease, your primary care doctor will likely monitor your blood pressure and conduct two simple tests to detect early signs of abnormal kidney function. One of them is a urine test to that detects persistent protein in your urine. When your kidneys are damaged, they do not properly filter protein, causing it to leak into your urine. The other is a blood test to check for creatinine, a waste product that comes from muscle activity. The results are used to estimate your glomerular filtration rate (GFR) – a measure of your kidney function.
Another important sign that doctors look for is hematuria, the presence of blood cells in the urine.
“Often people don’t have symptoms,” said Juan Kusnir, M.D., a nephrologist with Baptist Health South Florida. “They don’t have anything that raises a red flag at them and they say, ‘Oh I need to go see a kidney doctor.’ ”
However, adds Dr. Kusnir, there are symptoms that people should know. “They may get swelling (especially in the feet and ankles). They may have a sudden elevation in their blood pressure. They may have blood in their urine. Or they may notice that their urine is changing. The urine may become very foamy, very bubbly.”
