I have high blood pressure, well-controlled on medication for >10 years. At my last annual doctor visit, my bloodwork showed a blood sodium level of 125. My BP that day was 110/68. I take 50 mg atenolol and 25 mg hydrochlorothiazide daily, have lost 50 pounds in the last 18 months through diet and exercise. I drink a lot of water daily; the morning of the lab test, I was fasting and had drank 3 liters of water in the course of 4.5 hours. My doctor made me stop the diuretic for 3 weeks and retest; came back 124. Blood pressure shot up to 168/99; doctor was not concerned one BIT with that (or the accompanying edema in my feet, calves and ankles); only wanted me to be admitted to the hospital and referred to a nephrologist. She said I had “severe hyponatremia” and could die! I have ZERO symptoms of hyponatremia; when I refused her recommendation, she fired me from her practice and cancelled all of my prescriptions. Now my NEW doctor says I have “CHRONIC hyponatremia” based on two blood tests; blood sodium in early January of this year was 134. Why would I have zero symptoms if I’m so “sick”? And, would 3.5 months’ time be considered “gradual” or “sudden” onset?

Low blood sodium (hyponatremia) is relatively common in patients who take hydrochlorthiazide and drink an excess of water. The most common symptom of hyponatremia is gait instability and falls. This is more common in the elderly. One of the more … Continue reading

Hello. My now, 5 year old son, when I was pregnant, he had fluid on his kidneys and was born with hydronephrosis. He had his checkups every 6 months up until we moved to another country in 2016. He was doing OK. No problems up until 2 months ago, he had been complaining of back pain, so I took him to get a sonogram to check fluid and he had little, not as much as he had before, and he had blood and urine tests done. The tests came back that he had a kidney infection. He was put on antibiotics. After he finished his medicine, the pain continued so I took him to a kidney specialist and all he did was tell me to go get him a US renal sonogram and get his urine and blood work. So I took him to get the sonogram. Doctor said he had no fluid on either kidney. The right kidney was 86x33x37mm and 10.6mm, his left was 82x33x39mm and 13mm. Doctor said no fluid on his kidneys, which was a relief but she said his spleen was swollen. She told me a child his age should be 105mm but my son was 116mm and she told me to wait for his blood and urine test results to come back to see if it’s from an infection or if not, then it’s normal. I am still waiting on his results but my question is what should I do next? Who should I take him to next? Should I worry with us being in another country? The health care is not anywhere close to the United States and that has me worried. Do I take the results and sonogram information back to the kidney specialist or should I see someone else? Any and all help and information would be very much appreciated. If you need more information or any questions, please contact me.

I am an adult nephrologist and I have no expertise with children. I would offer two recommendations. In most cases, I would have your son evaluated first by a pediatrician, rather than going directly to a kidney specialist. A pediatrician … Continue reading

What are the effects of Stage 3a Kidney Disease? Can high doses of Calcium increase your Potassium level?

Chronic kidney disease (CKD) is generally without symptoms. This is why it is difficult to know whether you have kidney disease unless you get blood and urine testing for CKD. Early stage CKD may result in mild anemia and some … Continue reading

In March 2019 I went to see a naturopathic doctor because I was having panic attacks and my blood pressure would go up and I went to the ER several times. She did different stool/urine/blood tests and turns out I had H Pylori, parasites and worms, in addition to some kind of anemia and vitamin/mineral deficiency. She put me on different supplements to kill the h pylori and parasites/worms and different vitamins minerals I was lacking. I’m starting to feel better and my blood pressure is normal. In mid May 2019 I started noticing some bubbles in my urine. We did more blood/urine tests and it showed urine was cloudy, leukocyte esterase 2+, WBC 40-60, squamous epithelial cells 20-27 and Urea Nitrogen (BUN) 8. There was NO protein, NO nitrite found in urine. She said I had a UTI but I didn’t have any symptoms at that time. Now in June 2019 I did the urine strip test at home and it shows low levels of leukocyte, but everything else seems OK. I’m still seeing bubbles in the urine and I’m getting concerned. Does it sound to you like there could be something wrong with my kidneys or can all the supplements that I’m taking somehow causing bubbles in the urine? Should I see a nephrologist? Thank you for all your help.

I do not think a nephrologist would be helpful. I would suggest that you see an allopathic physician and have a general history and physical examination. I am not able to make a specific diagnosis based on the information that … Continue reading

Hello. I’m a 32 year old female and I’ve been having numbness in my hands and feet that doesn’t go away. I’ve gone to my PCP and she ordered blood work to check blood counts, diabetes, kidney function, liver function. She stated that all the results were normal but I’m concerned about the eGFR rate. The current blood work done on 6/14/19 shows a rate of 75 mL/min/1.73m2 with creatinine of 1.0 mg/dL. But when I had this same blood work done on 4/15/16, the rate was 124 mL/min/1.73m2 with creatinine of 0.60 mg/dL. Should I be concerned about the major drop in the eGFR rate? What would cause it to drop so much?

This may represent laboratory variation. I don’t know the accuracy of the laboratory that measured your serum creatinine. In normal laboratory variation, it is generally recognized that the serum creatinine can vary by 0.2 milligrams per deciliter (mg/dl) from day … Continue reading

Hello Dr. I am a male 36 yrs old, who recently found out he was born with one kidney. Can you tell me what are the guidelines for creatinine levels for a patient with one kidney? Mines is currently 1.4. Thank You.

Having a single kidney should result in approximately one half to two thirds of normal kidney function. This would mean that there would be an estimated glomerular filtration rate (eGFR) in the range of 50 to 75 milliliters per minute … Continue reading

Sir, 6 months back I had a stone in the right kidney, size 11mm. The stone was crushed and removed through urinary tract. That time my creatinine was slightly high, 1.5. After removing the stone, creatinine become normal. After a few days, I had a UTI and my creatinine went to 1.5. I took the medicines for the UTI and the creatinine went back to normal. 16 days later, my creatinine increased; the reading was 1.25 (reference- 0.6 to 1.1) and there was infection in urine. I took antibiotics. After 10 days of antibiotic course, my creatinine is 1.27 (ref- 0.6 to 1.17), and my TSH is 7.98. I have been suffering from High Blood pressure for the last 38 years. At present, I am taking Cilacar M and Cilcar 20 mg at night. Previously I was taking Telmasartin 40 mg + Amlodeepin 5 mg combination. But after the slight increase of creatinine, the medicines have been changed. I always feel dehydrated and burning in my urine. At night, I have to go to bathroom nearly 8 to 10 times to pass the urine, but day time I am OK. Please advise sir. What precautions should I take to protect my kidneys. My BP is around 130/90 or 140/85.

I am a 59-year-old woman with a solitary kidney. I had kidney cancer, and my right kidney was removed 3 years ago. My post surgery bloodwork for the past 2 and 1/2 years has shown my GFR to be in the mid to upper 60’s. But my last blood test 2 weeks ago showed my GFR is down to 46. Creatine is 1.28. My PCP wants to test again in a month. Should I be concerned that my remaining kidney is not functioning properly?

There is always some variability to the estimated glomerular filtration rate (eGFR). This test can vary up and down by 10 milliliters per minute (ml/min) from day to day. With only one kidney, your singe kidney eGFR should generally be … Continue reading
