I have 9 items (Bicarbonate, Sodium, Potassium,Chloride,Glucose, Alkaline Phosphate, Bilrubin,Total Protein and Albumin) which have increased in 2 months of testing. I was initially diagnosed at Stage 2 CKD and am seeing a Nephrologist near his own Dialysis Center. (I am not currently on dialysis) Is this common and normal?

Yes.  It is common for nephrologists to have offices very near dialysis units because as much as 50% of our time is spent evaluating and following up with people who are on dialysis. Having an office adjoining or near a … Continue reading

Hi, My brother is 46 and has been detected with CHF after heart attack last month. His LVEF is 30%-35%. He is Type-2 Diabetes and hypertension. However, these are under control now. He is 5.6″ and weighing around 83 kg currently. He just had a creatinine test and it came 2.4 which was 1.21 three months before. What does this mean and if it is a damage to kidney then can it be reversed? Please suggest. Regards.

I am unable to make a specific diagnosis based on the information that you present.  Your brother will need further testing in order to make a specific diagnosis as to the cause of his kidney problem.  Consultation with a nephrologist … Continue reading

Dear sir I am man and age 51, Bangladeshi. On 30-11-2019 my last creatinine level is 1.55. Is this danger level? How I can control it as 1.2? I am worried. Can you please advise me? How can I control?

In order to complete screening for chronic kidney disease (CKD), you should have a urine test for blood, protein, and infection.  I am unable to make a specific diagnosis based on the information that you present.  You will need to … Continue reading

I don’t have diabetes, high blood pressure or high cholesterol, what may have caused my CKD stage 3? My creatinine is 1.11. Thank you.

I am not able to provide a specific diagnosis based on the information that you present.  The two most common causes of chronic kidney disease (CKD) are hypertension and diabetes as you mention.  There are genetic causes of kidney disease, … Continue reading

I am a 33 year old caucasian male. I have a creatinine level of 1.41 & 1.38 mg/dl (recorded about 1.5 months apart) that was flagged high. Is that of concern? I take a daily protein supplement, physically active, and both these readings were taken in the morning when I didn’t have anything to drink in a 10-12 hours span.

It is difficult to interpret serum creatinine levels when I don’t know the laboratory that performed the test and I don’t know the laboratory normals. These results would likely be above the normal range but I can’t tell for sure. … Continue reading

Hello. I have been battling kidney stones for some time now. I was admitted in the hospital June of 2018 multiple kidney stones. And I just saw on my medical records, I have cyst on both kidneys. My problem is my kidney stays swollen up and hurts even more with any activity and it’s getting worse. What could this be and what should I do? I only make $10 per hr and no insurance. So I can not go to a urologist. I haven’t been back to hospital. I don’t know what to do on this. I just want to know kinda what I’m facing if you could help me here. I would greatly appreciate it. Thank You.

Recurring kidney stones are painful. The best treatment for kidney stones is to adopt a very low salt diet.  I am a strong proponent of the DASH diet. You should not use any salt at the table and no salt … Continue reading

I had right nephrectomy in 2012. I just recently had a sonogram to make sure my left kidney looks OK (and it does). The last lab results show eGFR non-afr. american at 53, creatinine 1.18, albumin 4.6. Urine test is negative for protein. I tried to figure out that albumin/creatinine ratio, but I am not sure if those two numbers should be combined. My question/concern is if, based on the eGFR value itself, I am already considered to be at the Stage 3?! Thanks in advance.

Removal of one kidney will result in a lower estimated glomerular filtration rate (eGFR) and will actually result in an eGFR that is about one-half of normal.  If the normal eGFR is between 90 and 120 milliliters per minute per … Continue reading

Hey Doc, Long time no talk. Quick question for you. I have been doing much better mentally. Seeing a therapist about anxiety and not worried about my kidneys. My 1.4, 1.54, 1.7, 1.4, 1.4, 1.2, 1.3 creatinine really scared me but after seeing two nephrologists, one er doctor, my physician and talking with you I feel confident no CKD. My 136.6 creatinine and no protein helped confirm this. I am eating 90% vegan as well and cut back working out for time being. My question for you is. Why if African Americans are more likely to have CKD than a Caucasian would they have their own formula to consider creatinine is better? I believe this is faulty. Would you agree? For example if it is all muscle mass related and body builders like myself have a much bigger mass than average african american why don’t more doctors realize this?

The CKD-EPI and MDRD formulas for calculation of the estimated glomerular filtration rate (eGFR) were derived from patients populations and it was noted that ON AVERAGE, African Americans have a larger muscle mass and a serum creatinine that is higher … Continue reading

Hi. I am desperately looking for advice. My father had a nephrectomy 11 years ago. Since then his kidney function had varied between 38-44gfr. He also suffers from high blood pressure. Can you suggest anything to regulate these numbers? What are the next steps or questions we should be asking? Regards.

I am unable to make treatment recommendations without performing a complete history and physical examination. I am unable to make a specific diagnosis based on the information that you present. Your father should likely be consulting with his primary care … Continue reading

My 83 year old mother-in-law was advised in January 2019 of a possible cyst on her kidney. She refuses any related medical treatment. Recent blood work shows a GFR of 25. She has some of the listed symptoms of kidney failure, including high blood pressure. She also has extreme food allergies which makes control by diet difficult. She says she’s ready to die – but we’re not ready to let her go yet. How long can she live without treatment? She’s frail but still on top of her mental game. Help!

I am unable to provide a prognosis without performing a complete history and physical examination. Conservative or non-dialysis management of advanced chronic kidney disease (CKD) means that we provide care for as long as we can and that your mother-in-law … Continue reading
