What Is Glomerular Filteration Rate?

Posted on Wed, 12 Feb 2014

Question: Hello, I recently had foot detox at a spa facility. The out come was my water turned yellow, indicating (according to the staff there) I may have kidney issues? I don't have high blood pressure or diabetes. No, problems that I'm aware of with my kidneys however I'd like to learn what my GFR is?

Brief Answer: GFR is glomerular filtration rate Detailed Answer: Hi, I appreciate your concern. I personally dont think that you might be suffering from any kidney disease. You dont have any longstanding illness like Diabetes Mellitus or Hypertension , which can predispose you to renal disease. Renal diseases manifest with decreased urine output,pedal edema, breathlessness,uraemic symptoms like nausea , vomiting or loss of appetite etc. In case you are having good urine output , normal appetite and no abdominal complaints, you should not worry. GFR is Glomerular Filteration Rate . It can be calculated by simple equation. It takes into account your age, sex, weight and Serum Creatinine levels. CrCl (male) = ([140-age] × weight in kg)/(serum creatinine × 72) CrCl (female) = CrCl (male) × 0.85 You dont need to worry , if your GFR is above >90 mL/min/1.73 m2. Hope it helps. . Dr. Kavita Paul

I appreciate your reply. Are you familiar with the foot detox I referenced? On occasion I have breathlessness after ascending stairs? May or may not be related? I had a stress test two years ago, it was normal for my age and condition. I have abdominal discomfort as it relates to PMS? As far as I know? I believe in preventive health care because too often when "we" become aware of health issues, its often too late? How can I go about having my kidneys checked just for my peace of mind? Do I need a script of some sort?

Brief Answer: Get your renal function tests Detailed Answer: Hi, Yes i have heard about these detox spas. Personally i dont really believe in them and i give same advisce to my patient, though i do believe that they work on some theory In case you want your kidney examination you can get your Renal Function Tests ,serum uric acid levels , serum electrolytes and complete urine examination along with ultrasound for Kidney size etc. Your local physician will know about this test. If your local doctor doesn't know, he/she can refer you to the specialist who knows about it. Drink plenty of fluids and maintain good hydration. Hope its helpful. Dr. Kavita Paul
