Doc, Three years ago I had kidney failure. My creatinine level was 10. I had no pain or illness, just out of my mind. Kidney Doc determined use of NSAIDs, Aleve, metformin, lisinopril made a perfect storm. Since, my creatinine levels have remained 1.0-1.04. No higher. I’m a 58 yo male, 5’9” 150 pounds. I’ve haven’t taken anything NSAIDs, metformin, and only 5mg lisinopril daily. I’m Type 2 diabetic. I have to take morphine sulfate 15mg x 3 and 10mg Oxycodone x 2 daily for chronic pain due to combat injuries. My kidney doc stated he moved me to stage 2 two years ago only because he couldn’t just move me from 3 to 1 automatically. Can I be considered cured? I long to drink a cold beer on a hot day.

After an episode of acute kidney injury, there is often residual kidney damage that has been done. I cannot determine if your kidney function is back to normal based on the information that you present. I suggest that you continue … Continue reading

I am unable to comment on treatment without performing a complete history and physical examination. The decision to start dialysis must be made by the physicians who are evaluating your son. There are specific indications for starting dialysis but the … Continue reading

Hi Doctor, I am a CKD patient and my creatinine levels and GFR keeps fluctuating. My last reports were Creatininine 1.4 & GFR 49 and report after that was 1.6 and GFR as 40. I don’t know what went wrong. Please help me. I am 30 years old married woman living in SFO.

The variation in your serum creatinine and your estimated glomerular filtration rate (eGFR) could just be normal laboratory variation. The laboratory measurement of creatinine can vary by 0.2 milligrams per deciliter (mg/dl) from day to day. I am not able … Continue reading

How do I lower my creatinine in urine?

The creatinine concentration in the urine is a reflection of your hydration. Hence, the more water that you drink, the lower the creatinine will be in your urine. This is not a reflection of kidney function but rather a reflection … Continue reading

I just received a blood test result and was shocked to see an eGFR result of 47. Quest did my blood tests. I had a test in March and the result was 66. On the 7th of June, the result was 63. On the 19th of June, the result was 47. In that period, the Creatinine number moved from 1.11 in March, 1.15 the 7th of June and then to 1.17 on the 19th of June. My BUN numbers have been steady between 15 -17. I received stents in my heart in February and was given Crestor at 10 mg per day. I stopped taking the Crestor on Wednesday and today is Friday, so the Crestor remaining in my body should be about 1 mg. I hope so much that by stopping the Crestor that the Creatinine number will drop. I am 72 years old. I am not fat at all. I do 40 minutes of cardio at the gym every day and walk 40 minutes a day briskly. Just within the last 30 days, I added 1.5 – 2.5 hours of Yoga a day. This has put stress on my knees and muscles in general. I have had frequent urination for years, but have no back pain or change in color of urine. Can you give me any thoughts you might have if this condition may go back to what it was before? One added thought is that the Lab is Quest. They changed their normal range for Creatinine from normal extending to 1.18 to normal only extending to .93. I am wondering if part of this dramatic change might be in the formula that Quest is using.

I am not able to make a specific diagnosis based on the information that you provide. The creatinine test is subject to some variability and may vary by 0.2 milligrams per deciliter and still be within the range of normal … Continue reading

Hello Doctor, my creatinine levels are high. Is there any medication to bring it down and cure my kidneys?

There are no medications that directly lower the serum creatinine. The medical approach to kidney disease is to establish a specific diagnosis as to the cause of the kidney disease. Once the diagnosis is made, then treatment is directed to … Continue reading

I need your expertise. I had my physical in March (turned 50). Had the complete exam as well as the entire blood panel (included everything). In March the Serum Creatinine came back at 1.07, all other results in the normal range. Then went back May 1st to get a BMP. Creatinine came back at 1.09 and the eGFR came back at 59 so my doctor sent me in for a Urinalysis and the Urine Creatinine, Urine Albumin and ALB/Creat Ratio all came back normal as did the Kidney Ultrasound. I don’t have Diabetes or High Blood Pressure (all normal) so would like to get your thoughts on the results. I was taking birth control and stopped taking it on May 1st. I don’t have any symptoms of any kind nor do I take any medication. I don’t even take aspirin. I exercise daily (strength training/cardio). I drink plenty of water and green tea. Rarely eat red meat either. Looking forward to hearing back from you. I submitted a question earlier today and am still waiting for his response. I wanted to give him another blood result #. Back in March my creatinine came back at 1.07 and my eGFR was at 61. In April my creatinine was 1.09 and my eGFR was at 59. According to my ranges the creatinine was in the normal range but the eGFR was not. All other tests have come back normal (i.e. urinalysis no protein in urine and kidney ultrasound nothing found, kidneys in good shape). I have no symptoms and feel great! I workout daily and have quite a bit of muscle but am not a bodybuilder. I do not take any supplements, vitamins or medications. I do not even take aspirin. I stopped taking my birth control (Gianvi) on May 1st. Please advise. Thank you!!!

I am not able to make any specific diagnosis of kidney disease based on the information that you provide. The laboratory test for serum creatinine has some variability. The two results that you describe are within laboratory error. The serum … Continue reading

Hi doc, I am diabetic patient. My creatinine is 9 and I am also anemic. What would you recommend to reduce creatinine level?

A serum creatinine of 9 milligrams per deciliter (mg/dl) suggests very advanced chronic kidney disease (CKD). There are no medicines that lower the serum creatinine. I recommend that you consult with a nephrologist in your country. These laboratory results suggest … Continue reading

I am 63 y/o F w/ multiple endocrine problems to include diabetes T2 & strong family history of both diabetes & CV issues. Maternal GF died of kidney failure secondary to diabetes. 11/17 Creat was 2.3 & this past April BUN=26, Creat=1.30, & GFR=44. PCP concerned when Creat=2.3, but does not appear to be worried with April’s results. What are your thoughts & should I be more proactive in pursuing this? Thank you.

The fall in your serum creatinine from 2.3 milligrams per deciliter (mg/dl) to 1.3 represents an improvement in your kidney function. That is certainly a welcome finding. I would also recommend that you have testing of the urine for blood, … Continue reading

I have seen the Doc recently for occasional gray/whitish stool. She ordered a bunch of labs. Most came back normal, a few were slightly high or low. I was googleing (not a good idea) the results and noticed the GFR was a bit low. I have a follow-up in a few weeks, but do these results look concerning at all or just low/high normal? I am 34 years old, male, 5’8″ and weigh 205. I exercise regularly and do not take any vitamins, supplements, or medications. I also have an ultrasound scheduled for thyroid (one side is larger than the other) and gallbladder area pain. I don’t expect you to provide any diagnosis, but anything to be concerned about or specific things I should bring up to my doctor? Calcium 10.1 mg/dL (Higher Than Normal) Creatinine 1.40 mg/dL (Higher Than Normal) Hematocrit 39.7 % (Lower Than Normal) RBC 4.23 x10(6) (Lower Than Normal) Eosinophils 3.6 % (Higher Than Normal) GFR 65.1 mL/min

I am not able to make any specific diagnosis based on the information that you present. Your creatinine test is higher than I might expect and your estimated glomerular filtration rate (eGFR) is in the low normal range but it … Continue reading
