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

Kidney function at 40 and have chronic diarrhea due to gastric bypass. Have taken massive amounts of Imodium to control bowels. Was suggested by family doctor as safe. Now I find out that this can damage kidney function. What OTC medication for diarrhea is safe for my kidneys?

Imodium (loperamide) is safe for patients with kidney disease.  I am unaware of any damage that Imodium causes to kidneys.  Patients who have gastric bypass and diarrhea are prone to kidney stones and also can have kidney damage from oxaluria … Continue reading

My father had a kidney transplant 2 years ago. He is suffering from urine infection and BKV virus from long time. Yesterday creatinine report was 3.5 and hemoglobin was 6.5. He is also a path of diabetes and BP. Please help what to do? Why creatinine is increasing ?

Patients who suffer from BK virus infection in the urine often develop chronic transplant glomerulopathy and this can lead to transplant failure.  Treating chronic BK virus infection is very difficult. I can only recommend that your father continue to follow … Continue reading

I am a 55 year old white female. I have been on blood pressure meds, cholesterol meds, anxiety meds, and Nexium for approx 15+ years. I recently had a screening and discovered that my GFR is 54. I have started drinking more water, but I have to urinate constantly during the day and night. I have been having back pain over the past couple of weeks – not just lower back, but also mid & upper back along my spine. What tests do I need to have done to determine whether or not my back problems are stemming from my kidneys? Also, if the pain is coming from my kidneys, is there anything that can be done for that? I have an appointment with my primary care physician tomorrow – do I need to see a nephrologist right away?

Pain is not a common symptom related to kidney disease.  Stone disease and infection may present with pain but chronic kidney disease (CKD) is most commonly without symptoms.  The best test you can have is to be examined by your … Continue reading

I am a 54 Caucasian female, 5’5″ with BMI 20. For the past few years, my GFR has been in the 70’s. my most recent GFR was 62. My most recent creatinine was 1.03. I have had microscopic for 10+ years, which I have attributed to multiple small stones in each kidney. I started having kidney stones at least 20 years ago. I have no known CKD risk favors. Question: Can having chronic small kidney stones influence GFR?

Chronic kidney stone disease is a risk factor for chronic kidney disease (CKD).  You may need to be evaluated by a nephrologist to determine the cause of your recurrent stone disease and see if the stones can be prevented.

Hello Doctor, My query is for my Mom. She is around 55 yrs of age, having diabetes and BP. Recently we took CT scan, and we came to know that she is having kidney stone in her left side. The report says “39×28 mm sized large branching calculus is seen in left renal pelvis, extending into lower calyx. Upper and middle calyxes are dilated and clubbed.” My query is what type of treatment required to remove it? Is it possible to remove the stone using “Lithotripsy”? Pls comment on it. She is diabetic but due to a controlled diet she is having 128 value after 2 hrs of breakfast. Though sugar is under control, would like to avoid going to surgery or Tunnel Surgery (Percutaneous Nephrolithotomy). Advance thanks for your reply.

The question that you ask is a urological question.  I am a nephrologist and have no expertise in regards to the surgical treatment of kidney stone disease.  I suggest that you consult with a urologist, who is a surgeon. For … Continue reading

Hi Doctor, I’m a 27 year old, Korean, healthy, female. My blood pressure is always very low and I’ve maintained good health for the most part. For more than a year, I have experienced kidney pain and tenderness the night of and day after I drink alcohol. I’ve always thought it was nothing to worry about since I had ingested alcohol and thought this was my body’s normal reaction. There was a time when I didn’t have these symptoms, but it’s been a long time. Recently, I went to my PCP because my kidney pain lasted a few days after I had drank alcohol. My doctor did a UA and my results came back as follows: GLUCOSE, UA Negative mg/dL; KETONES, UA 80 (2+) mg/dL; SPECIFIC GRAVITY, UA 1.027; UA HGB 0.03 (1+) mg/dL; PH, UA 5.0; PROTEIN, UA 30 (1+) mg/dL; NITRITE, UA Negative; LEUKOCYTE ESTERASE, UA Positive; UROBILINOGEN, UA, QL Negative; BILIRUBIN, UA Negative…. WBC’S, UA/HPF 6-10 HPF; RBC, URINE HPF 4-10 HPF; MUCOUS, UR SED, QL, AUTOMATED COUNT Present HPF; HYALINE CASTS, URINE SEDIMENT, AUTOMATED COUNT, QUAL 5-10 LPF. In July, my GFR was 86 mL and my Vitamin D levels were 16ng/mL. I have not repeated a blood test since July. When I spoke with my doctor regarding my results, she stated she ruled out a UTI and a Kidney Infection. She referred me to a Urologist and Radiology for an ultrasound. I have had a kidney infection previously in 2012. I can’t get into my urologist until April, so naturally – I’m scared. Do these results lean toward a kidney stone being present? Could it have been present for over a year and only agitate when I drink alcohol? Or do these seem to point toward diseased kidneys? I’ve lost about 12 pounds in the last couple months (108lbs, 5’3″) and have (in the last week) a decreased appetite. In the last four days, I have been experiencing a low grade fever and chronic, dull pain/heaviness in my kidneys. Since I have experienced a kidney infection before, I am reluctant to go to the ER to see a specialist sooner. Are these symptoms something I need to address sooner than April?

I am unable to provide a specific diagnosis based on the information that you provide.  I am a nephrologist and I cannot make a diagnosis of kidney disease based on the information that you describe.  I agree that you should … Continue reading

I am unable to make a specific diagnosis based on the information that you provide.  I suggest that you consult with your physician about having specific kidney function tests.  An estimated glomerular filtration rate (eGFR) of greater than 60 milliliters … Continue reading

I was just dx with CKD and calculus kidneys my lower back hurts all the time. Pain in the right side in my lower back and lower left in the back. Is this normal and of course I have fatigue and will go to my nephrologist on April 4. I hurt whether I have a kidney infection.

If there is a stone (calculus) in your kidney, then this must be evaluated and treated by a urologist, not a nephrologist.  I suggest consultation with a urologist. For more information on kidney stones click here:
