This morning my UREA/SUM LEVEL WAS 8.09, CREATININE 137umol/L, glomerular filtartion rate 48. How bad is this?

This would be consistent with Stage 3 chronic kidney disease (CKD). This level of estimated glomerular filtration would need to be present for at least three months in order to qualify as CKD. You can learn more about the Stages … Continue reading

Doc, my creatinine is 98.9. Is it normal? Please help.

The serum creatinine result that you quote of 98.9 has units of “micromole per liter or umol/L”. The normals for each laboratory is determined by each laboratory. Hence, you will need to check with the normal values published by the … Continue reading

I have pain in my back that continues to get worse. I went to the clinic and they said my tests seem normal and sent me home. My GFR was 97 a year ago and is 64 today. I know that it’s still within “normal” ranges but seems to have declined significantly. I don’t want to wait until it’s way bad if it is my kidneys. Is this something I should be concerned with? It was 94 in March and 88 in April and now down to 64.

The estimating equations that we use to estimate the glomerular filtration rate (eGFR) are not very accurate for eGFR’s greater than 60 milliliters per minute per 1.73 meters squared. Hence, numbers greater than 60 are subject to considerable variation from … Continue reading

Good afternoon. I am a 38 yr old Caucasian female 5’5″ 126 lbs. 1st a bit of history: I had PCOS and Endometriosis which resulted in a total hysterectomy in 2007. Followed by a Hashimoto’s Thyroiditis diagnosis in 2015. Followed by a positive past Lyme and EBV tests 2018. Now my blood tests are getting scarier. Now to current: June 2017 GFR rating was 95, followed by Feb 2018 GFR rating of 76, followed by Aug 2018 GFR rating of 63. High Hematocrit, Creatinine at 1.11, mildly elevated Cholesterol Total and LDL, elevated Albumin. Standard UA screen came back normal. I have pain on right side lower back that will shoot into leg, and arm causing cramping and sharp pains. I itch all over for no reason. I drink at least my body weight in ounces of water each day. I am and have been on a strict Auto-Immune diet which is very balanced. According to kidney.org and davita and a medical journal research article I read, I am currently experiencing CKD Stage 2 about to be Stage 3. It’s not uncommon for early stage to not show in a UA (catch it early). I’m making an appointment for a Kidney Ultrasound and looking for reputable Nephrologist that takes my insurance, that truly cares, is proactive and values a very involved patient. My PCP and I are not sure what is the root cause to the drastic GFR decline in the last year. If anything I’ve gotten healthier this past year with diet, stress reduction, getting my Hashimotos under control etc. I’m at a loss. What are your thoughts, ideas on possibilities, any recommendations etc? I’m young, a mother, a grandmother, a wife, a daughter, a sister and I’m scared.

First of all, Stage 2 chronic kidney disease requires that there be abnormalities of the urine, such as blood, protein or infection that has been present for at least three months. An estimated glomerular filtration rate (eGFR) between 60 and … Continue reading

Hi, I am a 70 year old male and about eight months ago I was told by my physician that I have stage 3 CKD. My GFR was 57 at that time. All other lab blood work was normal. I just had some follow up blood work and the GFR is now 53 (all other labs are normal). Should I be concerned? I have stopped drinking coffee and started drinking tea (usually 4 cups a day). Is it safe to drink tea? Thank you.

The laboratory is unable to reliably differentiate between an estimated glomerular filtration rate (eGFR) of 57 milliliters per minute per 1.73 meters squared and 53. These numbers are essentially the same and within normal laboratory variation. The kidneys likely do … Continue reading

I have had low kidney function for several years, and my last GFR non African was 47.4 the lowest score yet. I won’t be able to see my GP and arrange testing until November. Should I go to a walk-in clinic to request testing in advance? If so, which tests?

I generally recommend followup of chronic kidney disease (CKD) which is in Stage 3 every 6 to 12 months. An estimated glomerular filtration rate (eGFR) between 30 and 59 milliliters per minute per 1.73 meters squared is defined as Stage … Continue reading

I was wondering what insulin/diabetic medicines are the most gentle/safe for a person with one kidney? I had one kidney removed last August due to kidney cancer. Trying to keep my other kidney healthy and was told Metformin and so are some insulin products. Any information would be greatly appreciated. Thank You.

Metformin is now acceptable for patients with an estimated glomerular filtration rate (eGFR) greater than 30 milliliters per minute per 1.73 meters squared. Metformin is a safe and effective medication for patients with diabetes and chronic kidney disease (CKD). The … Continue reading

Good morning, I am 59 1/2 years old and was told at my annual physical yesterday I am at stage 2 CKD. I have hypertension controlled, Metoprolol 25mg, no other risk factors. My GFR was 79, urine was clear. Family history father + for diabetes Type 1 and hypertension. Mother has CKD and hypertension. Grandmother lost a kidney, history unknown. Should I be concerned? See a nephrologist? Thank you.

I typically recommend that you consult with a nephrologist when your estimated glomerular filtration rate (eGFR) is less than 30 milliliters per minute per 1.73 meters squared. Most primary care physicians (PCP’s) are capable of managing early stage chronic kidney … Continue reading

I have chronic kidney disease due to upj obstruction. My right kidney is functioning 27% and the left is 73%. I also have Type 2 diabetes. I’m not over weight nor do I have high blood pressure. I had a stent put in for hydronephrosis. I have a urologist but should I see a nephrologist?

I suggest that you consult with your primary care physician (PCP) to see if referral to a nephrologist is necessary. In most cases, your PCP should be able to manage early kidney disease. If complications arise, then referral to a … Continue reading

Hi, I am on a fact finding mission and if you can give me some answers on my kidney. In 2008-2012, my kidneys function was at 75-80%. I took Ibuprofen 500 mg for pain for 4 years. I saw my chart 2013 my kidneys are working at around 38%. Is there a way to reverse this problem? Seeing other MDs in my town can or will not give me an answer?

If your kidney function, as estimated by your glomerular filtration rate (eGFR), has stayed at less than 40 milliliters per minute per 1.73 meters squared and has been so for at least 3 months, then you have chronic kidney disease … Continue reading
