In the last 3 weeks, I've been feeling really thirsty, resulting in drinking more water than normally and peeing a lot more. So, I went to the doctors earlier in the week and they did a blood and urine test.
Saw the doctor today and he said that no diabetes is present, however I have a "disappointing" GFR of 58, (90+ as normal) which is low for someone aged 45.
When I went in to get my blood tested, I hadn't eaten for 12 hours and I think I may have been a little bit dehydrated, if that makes any difference?
Anyway, he said I should cut out chinese and curry, stop drinking carbonated drinks and don't put salt on my food for the next month. Then they will do the test again.
With a reading of 58, is there any chance that I could have a much higher reading when I go back in a months time? Can diet make a change like that over the next month, or has he only said that to avoid more damage to my kidneys?
I am sorry about your GFR result. Your doctor is going to re-test your blood and urine. The lab results will confirm whether your kidney function has decreased.

Our kidneys compensate for any kidney problems that develop. The kidneys go into an overdrive mode and keep going. This is good, but it also means that many kidney diseases go undetected until there is a substantial loss of kidney function.
Initially, there are no symptoms. Increased frequency of bathroom breaks could point to kidney or several other health issues. I am glad that diabetes has been ruled out.
Moderate or severe dehydration affects the kidney function negatively and can result in a lower GFR test result. I am not sure about the severity of dehydration that occurs after a 12 hour fasting period.
How is your blood pressure? With reduced kidney function, there is a good chance it may be elevated. Are you on any anti- hypertensive medication? Some medications that affect creatinine levels (creatinine level is used in the calculation of GFR) can cause the GFR to appear higher or lower than it actually is. Decreased blood flow to the kidneys, being very overweight, or a vegetarian, a body-builder type with a lot of muscle mass or a person whose muscles are wasting are some of the other things that may affect the GFR test results.
Carbonated drinks can contribute to chronic dehydration and are bad for you. The BEST thing we can do for ourselves (regardless of the GFR level) is to cut back on our salt consumption.
Do not eat a lot of protein the night before your next test.

Only your doctor can tell you this. I have been told that kidney function fluctuates and have seen that happen with mine. It can go up and improve quite a bit!!! That is why it is so important to try to eat healthier, less salty foods. It is good for the kidneys, the heart and other organs. Reducing our sodium consumption to recommended daily amounts allows us to have better blood pressure control and to remain healthier.

I'm in Canada. Btw, the eGFR is the same in Canada, the US, and the UK. It is the creatinine that is different. Some labs measure differently, but in general, you are not that far off the mark. What is your creatinine? That is a better indicator as the GFR is an estimate and not that accurate.
The GFR (glomerular filtration rate) is always estimated. It is more accurate for men than for women, but it is still an estimation. It's not the best thing to base treatment on or even diagnosis although it is a part of the entire process.
Keep in mind, that even if you are at stage 3, you may remain stable for a long time. Especially if you maintain proper bp control and limit salt and animal protein intake.
I wouldn't cut out favorite foods or eating out once in a while, but I would cut back on the shaker.
By remaining stable, it is possible for the results to stay the same for an extended period of time. Especially with the introduction of things like ACE inhibitor drugs that have been shown in some cases to even reverse kidney disease. Has your doc placed you on this med? It is considered the gold standard.
BTW, are you seeing a family doc or a nephrologist? It is a good idea to see a neph if at all possible as they will know all the latest tricks to keep your kidney as healthy as long as possible.
My thirst is not to do with my diet change. I felt thirsty and so went to the docs with suspected diabetes. I hadn't even heard of the word "renal" before at that stage! Then they did blood tests and found a low GFR.
Got my test results back yesterday. They were 1 month on to see if a low salt diet had any effect. Before, my GFR was 58, putting me at stage 3 CKD. This time, it was 61. No protein found in urine with dipstick, so they are doing a more accurate test via a lab this time. Doc said if no protein in urine then I would not be classified as having CKD.
Got appointment in 6 weeks to have an ultrasound on my kidneys. Scared on what they might find.
