I am at stage 4 kidney disease. My question: If I take a multivitamin, like Centrum Silver, will this hurt my kidneys more?

A multiple vitamin such has Centrum is safe for patients with chronic kidney disease (CKD).

Below are the results of my latest blood work. This was reordered because my potassium on earlier bloodwork was 5.9. Based on below would you suspect some sort of kidney problem and should I consult with a specialist?

I do not identify any kidney disease based on the information that you present.  In some cases, laboratory errors may occur. I suggest that you have urine testing for blood, protein and infection as well as the blood testing.  I … Continue reading

After a kidney stone removal operation, can the scar be a vertical line – running from the lower rib cage to the navel (belly button)? Can you please provide me with photo’s of – or refer me to where I can download photo’s of the scar(s) a patient could have after such a procedure ? Thank you very much for your time.

I am a nephrologist and not a surgeon.  A urologist performs kidney surgery and I have no expertise in surgery and do not know where different incisions may be made for different surgeries.  I suggest that you ask your urologist … Continue reading

I am a healthy 24 year old white male taking 1 gram of Valtrex/day for the last 18 months. I have no symptoms but on a routine blood test my kidney functions were Cr of 1.87, BUN of 27, BUN/Cr ratio of 14 and a eGFR of 49. Urinalysis shows no protein. I discontinued Valtrex 5 days ago and will have a second blood test plus a 24 hr urine collection. My question is: is increasing intake of fluids and possibly consuming cherry juice as it’s done for gout help my kidneys recover from crystal deposition? I have no medical problems, my BP is 110/70.

The testing that you describe, if it remains abnormal for more than 3 months, does suggest that you have chronic kidney disease (CKD).  I am unable to make a specific diagnosis based on the information that you present.  If you … Continue reading

I underwent a nephrectomy on April 3 whereby my left kidney and large tumor was removed. I have had a number of blood tests since then and have noticed that my BUN and creatinine are not within normal ranges BUN (35) creatinine (1.70) and my egfr is currently (June 13,) at 40. Should I be concerned at this point? I assume that without one kidney it would be low.

After undergoing removal of a kidney, your kidney function tests will be abnormal and the estimated glomerular filtration rate (eGFR) will be low.  After removal of one kidney, I would expect the eGFR to be in the range of 50 … Continue reading

Hi Dr. Spry — 39/yo amateur bodybuilder here. I learned a couple years ago that I have kidney dysplasia, one side completely polycystic kidney and the other mildly hypertrophied. I am used to my creatinine running high (over 1.3) and GFR just shy of 60. However some recent labs have disturbed me! Serum Creatinine 2.0 — note that I weigh ~100kg/225lbs largely muscle, this has crept up over time correlated with my weight gain (1.3, 1.5, 1.7, 1.8…) 24 hr urine contained 2.3g protein! — note that I didn’t know not to train, and trained legs (intensely) the day of sample collection eGFR 35-40 — could this be related to creatinine? BUN 44 — Note that I have been on very high protein diet, upwards of 4g/kg (400-450g total) I have been on Losartan for hypertension for about a year and a half. My BP is usually well controlled. Due to some other chronic illness (HIV, well controlled CD4 healthy normal range) I track my lab values in a spreadsheet. I can see a correlation between my weight/muscle gains from 200-220lbs and the increased serum creatinine and reduced eGFR. When I learned that I had the kidney dysplasia I had a proper radioactive measurement, and all I have in my notes is that GFR was fine and healthy for one kidney. Questions: 1. Is it possible/believable that this is all caused by my atypical muscle mass and intense training? (High creatinine, thus low GFR, exercise induced proteinuria) 2. With the kidney dysplasia, do I technically have CKD with basically 50% of a normal person’s kidney function? I am freaked out thinking that I’ve suddenly in the last 9-12 months had some sudden kidney injury!

By definition, you have chronic kidney disease (CKD) because the dysplastic polycystic kidney has been present for at least three months.  Hence, you do have reduced kidney function.  The body building that you are doing will increase the serum creatinine … Continue reading

My labs came back showing creatinine 0.8, no protein in my urine yet it showed my egfr as 73. I am a 54 Caucasian female and was wondering why my GFR shows 84 when I use an online gfr calculator. Why does my labs (blood work) show it much lower?

The online calculator calculates the estimated glomerular filtration rate (eGFR) in units that include your body size and is adjusted to a body surface area (BSA) of 1.73 meters squared.  The number can be changed by either including your body … Continue reading

Good health to you doctor! It’s been 2 months since I go through hemodialysis procedures on the Artis machines. Upon admission to the hospital, urea 26, creatinine 1300. There were no external factors of chronic renal failure. After the procedure of hemodialysis, the legs and feet began to swell for the 5th time. Can you please tell me how to make a hemodialysis program correctly? To me 52 years, the dry weight of 89 kg, body height of 188 cm.

I am unable to recommend dialysis treatment without performing a complete history and physical examination.  I suggest that you discuss your concerns with your nephrologist.  If you still have swelling in your legs and feet, then perhaps more fluid must … Continue reading

I have a kidney eGFR was 38. Then prescribed Metformin 500 mg 1in morning. Now my eGFR is 27. I think it’s because of metformin? Is it possible?

Metformin is a drug used to treat diabetes and should not be used with an estimated glomerular filtration rate (eGFR) less than 30 milliliters per minute per 1.73 meters squared.  Metformin may cause liver injury with a low eGFR but … Continue reading

Hi, I’m 55 years old. I had a kidney infection back in December and another one two weeks ago both showing blood in urine and decreased kidney function. Last week, blood tests yielded Creatinine 1.15 and GFR Non African American 54. My family doctor said that we should monitor for now and that I am in Stage 1 of renal failure. On charts that I have looked at, the numbers that I have seem representative of Stage 3 renal failure and maybe a change of diet is needed or perhaps a visit to a kidney doctor. Are the numbers truly representative of Stage 1 or Stage 3? Should I see a kidney doctor?

The Stages of chronic kidney disease (CKD) require that a test be abnormal for at least three months before we designate them to be CKD.  We do not refer to them as stages of kidney failure.  Kidney failure implies kidney … Continue reading
