I am concerned about my kidney function. I am a 56 years old, white male in seemingly good health. About three years ago the doctor measured my GFR at 93. A year ago, my GFR had dropped to 82. I also had a kidney stone removed at that time. My GFR is now at 83. I’m concerned that my creatine levels increased so abruptly. How concerned ought I be about this? Should I have more tests run? What should I do now? FYI: I am generally healthy, except for occasional bouts with constipation (especially on weekends and long holidays). All of my other serum levels are normal (see below). My doctor is tells me I’m healthy, but based on what I found here (looking up GFR), it looks like I have Stage 2 kidney disease. My diet is very similar to the DASH, except that my wife likes to cook with a little more salt than I wish. My weight is good (I’m 5’8″ and 135-145 lbs). Also, my GI doctor had me on Nexium for nearly 3 months for gastritis. Recent Serum levels: SODIUM 137 POTASSIUM 4.5 CHLORIDE 102 GLUCOSE 80 UREA NITROGEN 9 CREATININE 1.01

I do not identify any kidney disease based on the information that you present.  There is some variability to the estimated glomerular filtration rate (eGFR) and the two levels that you mention are within the usual range of variability for … Continue reading

I am taking blood thinners for a clot in my leg. I have stage 3 kidney disease. What are the risk?

Patients with Stage 3 chronic kidney disease (CKD) can take blood thinners but they should be carefully monitored with blood testing and monitored for bleeding.  Most blood thinners are approved for use in Stage 3 CKD.  You should discuss your … Continue reading

I am a female, age 58, no diabetes, or high blood pressure, recently tested GFR 48, down from GFR 68 twenty days ago. I have fluid retention and a lot of back pain with fever 100 – 102. No UTI (but suprapubic pain). Urinalysis: No protein, Leukocyte (70), hemoglobin small, all other normal. Doctors point at creatinine level (1.17) and believe due to dehydration and other symptoms not related to kidney. No referral to urologist, no diagnosis of kidney disease, no treatment offered for symptoms. Any recommendations to treat symptoms — now can’t work/function. Thanks. (p.s. I know need to push for more tests).

I am unable to make a specific diagnosis based on the information that you present.  I agree that you need further testing.  I suggest that you consult with your primary care physician for further testing or referral.  An ultrasound examination … Continue reading

I have type 2 diabetes. My last blood test shows my GFR is 41. My Doctor recommended that I drink 64 ozs of water daily but I see on different kidney websites that liquids should be limited. Should I follow her advice. She is a general practitioner and not a kidney or endocrine specialist.

I would recommend that you continue to drink water and avoid dehydration.  Water should only be limited if you are on dialysis or have significant problems with heart failure.  I do not recommend limiting your water intake with Stage 3 … Continue reading

Hello! I am a 34 year old female. At my last physical my doctor informed me she wants to monitor my kidney functions more & wants me on a diet because my GFR labs were in 2015 or 14 (can’t remember which year she stated) were at 110. My next 6 month checkup my GFR was in the 80’s, my next 6 month checkup the 70’s and now my check up on 3/31/17 my GFR was 63. I do not have high blood pressure but at 5’2″ & 175 lbs I am overweight. I don’t have diabetes although it is in my family history. She plans on seeing me in 6 months as usual and I am dieting & exercising in the meantime, but should my doctor and/or myself be way more concerned with this & see someone about it? My ankles are swollen with pitting edema from the calf down year round without let up. This edema has been since I was 20 and only 124lbs. Any insight you can give me would be greatly appreciated! It seems that my kidneys are functioning at the rate of an elderly person & I am a single,divorced mother of my 3 beautiful children so I really want to stay on top of this.

You physician is doing the proper monitoring.  I would also suggest that you have urine testing for blood, protein and blood.  This should be part of your monitoring in addition to measurement of your estimated glomerular filtration rate (eGFR).  You … Continue reading

eGFR = 159 Creat it on = 61 What does it mean Doctor?

The information about kidney function tests that you provide suggests normal kidney function.  I suggest that you also have urine testing for blood, protein and infection.

Hello Dr., I have CKD, my egfr is about 51-59 and my creatinine is about 1.11. I want to take magnesium, as when I do, it makes me feel good. What type and dosage should I take? Should I take it in combination with calcium and D3?

I am unable to recommend medication without performing a complete history and physical examination. I suggest that you consult with your primary care physician about taking magnesium supplements.  Magnesium can be tolerated by most people but you should always check … Continue reading

My doctor really doesn’t say anything but that I should watch for kidney disease. He said to cut down on desserts and no wine. I don’t drink but I guess the blood test shows something. I do drink Kombucha Tea. I have quit drinking that. My creatine 1.12, BUN 24, glucose 125, alt 45. I have to say my doctor said very little but he has caused me to worry as I am my husband’s caretaker. Can you tell me just how bad my kidneys are?

I do not identify any kidney disease based on the information that you provide.  You can go to our web site and calculate your estimated glomerular filtration rate (eGFR) in order to understand your current level of kidney function.  You … Continue reading

My serum BUN was 27. My eGFR was 56. But because my urine protein was negative the doctor said there was no kidney involvement. Do you suggest any further testing?

I would only suggest that you wait 6 months and see if the estimated glomerular filtration rate (eGFR) improves.  If it improves, then your doctor is correct.

My GFR level is 54. A urinalysis was performed and protein levels came back within normal range. Trying to drink more water causes me to have to go to the bathroom all day and between 3 – 4 times during the night. Should I see a nephrologist or urologist based on this since my GFR level indicates I am in Stage 3 Chronic Kidney Disease?

You may have early stage chronic kidney disease (CKD).  Most primary care physicians (PCP’s) are well capable of providing care for early stage CKD.  I do not usually advocate nephrology referral until your kidney disease progresses to Stage 4 or … Continue reading
