Environmental exposure to lead has been associated with decreases in kidney function. Lead is present in the environment from many things including diesel fuel and coal burning, so even if you aren’t eating lead paint, you are still being exposed. According to a study by Dr. Ha-Liang Lin published in the New England Journal of Medicine: “low-level environmental lead exposure may accelerate progressive renal insufficiency in patients without diabetes who have chronic renal disease.” The American Kidney Association recently changed the guidelines which determine kidney damage, increasing the number of Americans who are diagnosed with it. If you look at recent labwork, and find your eGFR, it will give you staging information about kidney disease and an estimation of how well they are working.
The good news is that in the previously mentioned artice: “Environmental Lead Exposure and Progression of Chronic Renal Diseases in Patients without Diabetes” the authors found that repeated chelation therapy with CaEDTA can improve renal function and retard the progression of renal disease. If you have been diagnosed with impaired kidney function, chelation therapy may be a great option for you to maintain or improve that function over time.
