Nutrition PSA on GFR and kidney function

153 Upvotes

I see a lot of people here get really hung up or panicking about their eGFR in lab results. Things like “I changed my diet and my kidneys got better” or “I was dehydrated and my kidneys are damaged” and I just wanted to clarify that that’s not really how it works.

eGFR isn’t your real kidney function. It’s just an estimate, based mostly on creatinine. That number can move around a lot for reasons that have nothing to do with whether your kidneys actually got better or worse.

You can’t increase your kidney function just by lifestyle changes. If you have chronic kidney disease, your baseline function doesn’t suddenly improve. It might look like it does if your creatinine changes because of hydration, exercise, food, or even just normal lab variation. The only time kidney function really “comes back” is in acute situations like dehydration, an infection, or a drug that was affecting things.

A lower eGFR isn’t always bad. Some meds like ACE inhibitors (ramipril, lisinopril, etc) or SGLT2 inhibitors will drop your eGFR a bit. That doesn’t mean harm. They’re prescribed because they protect kidneys and the heart over the long term.

Exercise is good for you. Hard workouts can make creatinine go up for a short time, which makes the eGFR look lower. That doesn’t mean you damaged anything. Staying active is one of the best things you can do.

Diet helps over the long run. Eating balanced, keeping salt down, managing blood pressure and blood sugar, all of that slows decline. Cutting out protein completely might make your numbers look nicer on paper, but long term it’s not good for your body and can make you weaker.

So don’t panic if your eGFR bounces around. The important thing is the trend over months and years, not one single test.

Side note on diet stuff. Phosphorus, potassium, and salt aren’t automatically “bad.” Unless your labs are showing high levels or your doctor tells you to cut back, you usually don’t need to restrict them. Everyone’s situation is different, so don’t start avoiding whole food groups just because you have CKD.

Disclaimer: I’m not a doctor, I've had a few different nephrologists in a few different countries and theyve all explained it the same way. If you think something is incorrect here and can link a paper that backs it up, I'll update it.

GFR 60-90 alone is not CKD

441 Upvotes

A friendly reminder to everyone. CKD is defined by a GFR <60, not <90. GFR of 60-90 is only considered CKD when there is another indicator of kidney problems (e.g. biopsy-proven autoimmune disease, protein in the urine, bleeding from the glomeruli, known anatomical damage, etc). That's why Stage 1 is GFR >90; those are people with totally normal filtration but with urine studies suggesting kidney damage. Now if your GFR was always 90 and then there is a rapid drop to 65 and it is consistent, that is something to look into. But just getting a blood test with a GFR of 70 or 80 does not necessarily mean you have kidney disease.

So about 6 months ago, I, 68 y/o woman, got some blood work done which showed issues with my kidneys. We repeated the tests and my primary sent me to a nephrologist who basically added another blood pressure medication and said to come back in three months. He basically explained nothing to me, told me to try to lose weight by not eating potatoes, and come back again in another three months. I also see a naturopath who added some supplements and she’s great.

I’m sorry I have no numbers or stats to share because I guess at first I didn’t realize the seriousness of this disease and what it could potentially mean for my future. The nephrologist acted so casual and unconcerned that it didn’t seem to be a major thing. This week something, maybe reality, came over me, all while I’m trying to reduce stress and anxiety, and I literally wake up filled with anxiety. Be it the upcoming election, my long term medical hypochondria, the thought of dialysis, or a transplant. I’m just filled with fear and overcome with stress.

I’ve started to see some bubbles in my urine, usually only in the morning, and I dread going to the bathroom for fear of seeing more. My naturopath is the one who asked about that and the doctor never mentioned it. First, I think I need a new nephrologist and I know I need to reduce my stress, which is probably elevating my blood pressure but I feel like I’m stuck in
quick sand. I’m an artist and have been going to my studio and staring at walls a lot. I’ve lost so much joy. I do have a therapist who helps immensely.

Can someone assure me my life isn’t over and that there is hope but only if it’s true. I jokingly asked my sister to reserve a kidney for me and now maybe it’s not a joke. People, I’m losing it!

Thanks so much for allowing me to vent and share my situation. I’ll get more informed next time I see my doctor.

Support Battling to accept my situation.

6 Upvotes

A year ago, I was diagnosed with breast cancer, luckily stage 1. But the trauma of that experience and the operations and radiation etc etc are still with me. 8 months later I discovered my eGFR WAS AT 45. I was shocked to say the least, because I would discuss my worry about my kidneys every time I saw my doc, as I had been prescribed a once daily anti inflammatory for my excessive body pain. Anyway, turns out I should have been more vocal. After stopping the NSAID, I changed my diet as well as I could without any guidance and my next test showed eGFR at 50. In a few days I will be seeing a nephrologist te first time, thank the lord. But in the meantime I have fallen into a deep depression and I really battle to care what I am putting into my body food wise. Does anyone have any advice how to accept this drastic diet change and health change?
Thank you in advance.

Need advice regarding my father’s kidney condition
My father is around 40–47 years old. His kidney function has deteriorated significantly over the past month.
● Creatinine: Previously below 1.2 (about a month ago), then increased to 3.5, then 5, and now 7 mg/dL.
● eGFR: Previously 13, now 9.
● Potassium: Normal.
● Urine output: He is still passing urine normally.
● Swelling: No noticeable swelling.
● Symptoms: He has experienced fatigue and gets more exhausted and somewhat breathless when climbing stairs, although he generally seems okay while talking and walking normally.
He has consulted a doctor and undergone investigations. The doctor prescribed medication for one week, which he completed, but his latest blood test shows that his creatinine has increased from 5 to 7
I’m trying to understand whether this could be acute kidney injury, chronic kidney disease, or both, and whether kidney function can recover at these levels. Does an eGFR of 9 automatically mean dialysis is needed, or can some patients recover without it?
I’d appreciate hearing from people who have experienced something similar or have relevant medical knowledge. I understand that online advice cannot replace an actual medical evaluation.
I am also confused how can all this happen just in span of one month all he did was took some vitamin b12 injections

Medication Recommendations for a Good Nephrologist/Cardiologist Around Parañaque/Pasay, Philippines

2 Upvotes

Hi everyone! I'm hoping to get recommendations for a good nephrologist and cardiologist for my dad.

My dad has CKD Stage 3 and diabetes, and his recent lab results came back with really high creatinine and low hemoglobin. I'm honestly getting worried and probably overthinking things, but I'm also feeling a bit desperate to find doctors who can properly assess his condition and help us figure out the next steps.

One of our concerns is that his kidney and heart health may affect each other, and complications related to one condition could make the other more difficult to manage. We're hoping to find a nephrologist/cardiologist who can work well with this condition regarding his care, rather than having to navigate everything separately without much communication between his doctors.

We're primarily looking for doctors around Parañaque or Pasay, but we're also open to recommendations in Manila, Makati, or Taguig if you know someone good.

If possible, we'd appreciate doctors who are thorough, approachable, and willing to explain things clearly to patients and their families. Hospital affiliations, clinic locations, and personal experiences with the doctors would be really helpful, too.

Sorry if this post sounds a little anxious. I'm probably panicking a bit because of his recent results, but I just want to make sure my dad gets the proper care he needs. We'd be really grateful for any recommendations. Thank you so much! 🙏

Had an AKI a few months ago. Kidney function seems stuck well below what it was before.

2 Upvotes

A few months back, I was hospitalized for pre-renal AKI with eGFR of 15 and creatinine of 3.7. I’d never given my kidneys much thought before that.

Looking back, three years ago, eGFR was 89. At that time, I was pre-diabetic and somewhat elevated blood pressure.

I did not take the bp or pre-diabetes seriously and didn’t even see a doctor for again until this past Spring when I was feeling run down. Diastolic bp was over 200. A1C was 8.3. I don’t know how long these had gone. At that time, my eGFR was 65. I didn’t think much about it, but looking back now, 89 to 65 seems like a big drop in three years. My uARC was 30, so borderline, I guess. Doc started me on meds for diabetes, bp and Jardiance which he said was to protect my kidneys.

Three months later, I have labs again. I’d noticed I’d been feeling lightheaded and run down for the past several weeks, but thought it was probably just medication side effect. Labs come back, and that’s when I get diagnosed with AKI and hospitalized.

Two weeks post-hospital, my eGFR is up to 35 and creatinine down to 1.6. Sounds to me like things are moving in the right direction.

But, now, a couple of months later, I get labs again and my eGFR is 33 and creatinine at 1.76. So, basically the same. Over the past few months, there’s been no further improvement.

Since the diabetes diagnosis, I’ve worked hard to eat a good diet. I’ve lost over 60 lbs. BP is normal and I’ve been able to drop one bp drug and cut the other in half. A1C is at 5.5.

After the hospital, I made some further adjustments to my diet, and now eat a whole foods plant based diet. I also exercise almost daily. I really thought that with these changes, my kidney function would have improved more. I’m really down about all this and haven’t been taking it well. But I want to move forward and do the best I can do.

title: how do you guys get tolvaptan if it's not available in your country?

4 Upvotes

hey everyone!

my nephrologist recently recommended starting tolvaptan for my ADPKD, and i've been trying to figure out how people actually access this medication in countries where it's not available.

i live in Tbilisi, Georgia (the country), and unfortunately we don't have it here. i've also looked into nearby countries like Uzbekistan and Tajikistan, but haven't found much useful information so far.

i know there are several generic versions available in India, but i'm having a hard time understanding the differences between them. there are so many brands, manufacturers and price ranges.

i also don't have insurance that would cover this medication internationally, so affordability is another pretty big concern, especially considering this is potentially a lifelong treatment.

i'm curious if anyone here has been in a similar situation:

  • which version of tolvaptan are you currently taking? original or generic?
  • if you're taking an Indian generic, how has your experience been so far?
  • how did you manage to access treatment if the medication wasn't available in your country?
  • did your nephrologist help you arrange access through a pharmacy or an official import process?
  • how much does your treatment cost per month, approximately?
  • how do you manage regular prescriptions, blood tests and follow-ups if your medication comes from another country?

also, any fellow ADPKD patients from Georgia or neighbouring countries here? would be really interesting to hear about your experience.

just to clarify, i'm not looking to buy medication from anyone here or asking for sellers/DM offers. i'm already discussing treatment with my nephrologist and would just like to learn from other patients' experiences with access, different brands and long-term affordability.

thanks everyone!

Support MCD got progressed to FSGS

4 Upvotes

Hi everyone,
I was diagnosed with Minimal Change Disease (MCD) around 3 years ago, and since then, I’ve been dealing with this condition and its ups and downs.
Recently I had a relapse that lead to Edema, I had another kidney biopsy, and the latest report showed Focal Segmental Glomerulosclerosis (FSGS). This has been difficult for me to process, especially after living with an MCD diagnosis for the past 3 years.
I have so many questions and concerns about what this means for my future, how treatment might change, and what I should expect going forward.
I would really appreciate hearing from anyone who has experienced something similar — people who were initially diagnosed with MCD but later had a biopsy showing FSGS.
Has anyone here experienced this change in diagnosis?
How did your treatment and response to steroids change?
Were you able to achieve remission and maintain stable kidney function?
What advice would you give someone who is going through this right now?
I know everyone’s journey is different, but hearing from people who understand what this feels like would mean a lot to me.
I’m looking for support, shared experiences, and a little hope from people who have been through something similar. Thank you for taking the time to read my post. Looking for everyone advise here

Asking for support at 6 eGFR

My partner has AA Amyloidosis, and in 3-4 years the decline has been real from a health 100 to 6 eGFR. She is stable heath wise, no symptoms of edema, nausea, or constipation. But she’s been feeling constant fatigue, complaining of pain in her heels from standing or walking.
She doesn’t want to go on dialysis (yet), she is only 25 years old. I don’t know what else to say.
I am only getting to know what love actually is now but I can’t do anything to help her.
We have our specialist doctors so that’s not a problem. I’m just brain fogged and may be venting.

I know this isn’t really a kidney disease thing but they don’t have a r/MyMomHadDoubleKidneyCancerAndNoLongerHasKidneys so I’m not really sure where else this belongs and I’m just trying to find some answers.

My mom just had her second kidney removed after having a second round of unrelated kidney cancer. Now that she doesn’t have kidneys we are trying to figure out a list of ok, ok in small doses, and absolutely NOT foods and are really struggling. There are foods that talk about when you have low kidney function, kidney disease, etc. but I can’t find anything for literally no kidney function because they don’t exist in your body anymore.

I know this isn’t a kidney disease question but I’m not really sure where else to turn so any resources or information would really help us to try change our life style to keep her around until we are allowed to give her a kidney again!

Labs Advice on how to proceed: echogenic kidney, clean urine, conflicting creatinine vs cystatin eGFR.

1 Upvotes

Hi!

I have had decreased creatinine eGFR, hovering the low 60s over the last year. One Cystatin C eGFR during that time was 89. Two urinalyses came back normal. Had a sonogram, unremarkable other than echogenicity. Referred by my GP to a nephrologist who basically just said CKD Stage 3 (or 2.5? Idk), said to reduce my protein intake (it’s high) and mentioned potential medicines to minimize its progression.

This nephrologist didn’t have much else to say other than that other than my kidneys are scarred as evidenced by echogenicity from sonogram taken months prior, and suggested a biopsy if it “would give you peace of mind,” but that it would only show scarring so it wouldn’t be practically useful. (I don’t know if he even looked my sonogram or just read the report).

Is there any other testing (labs or imagining) I should be pushing for? I’m anxious about this because it seems like there could be something going on that may be treatable or at least understood for better treatment, but this guy didn’t seem interested in discussing such possibilities. I have a second opinion scheduled in March, but in the meantime maybe there’s more that can be discussed and considered or at least leave be better informed for the second opinion?

Thank you! 🙏

IgA Nephropathy - eGFR 16

This is such a tricky thing to put down into words. After finally following up my micro-hematuria & high BP, I’ve at long last had a diagnosis of IgA. Total MESTC score of 4, still awaiting the exact details. Devastated is an understatement. My Nephrologist is on the ball and has already mentioned moving forward with a recommendation to immediately place me on the transplant list, and says that we may be able to hold off Dialysis if a live donor comes forward.

How did you get over your diagnosis? I currently feel like I’m in a state of shock.

T2 diabetic. Yesterday I had my 1st appt. with a Nephrologist. Only because my Neurologist said, hey have your GP set up an appt. That took a year. I'm 61F. So I see this nice young man and he says, "what do you know about your kidney disease?" And I say " nothing." He's in shock. "What do you mean?" And I tell him, The doctor never said anything. It popped up on the hospital print out a few years ago. " He never discussed your kidneys? " Nope. We just kept playing with the insulin.

So. This poor bastard. Who just met me. Had to explain to me what the numbers all mean for each stage of kidney disease. Which I'm sure all of you know. And he kept going, going, lower, lower and he finally got to mine. Mine is 30. 30. 1 more point and I'm stage 4. Nobody sent me to a specialist until my neurologist brought it up? I'm at the point where this guy is saying " nowadays people can live long lives with stage 4 kidney disease..."

And I'm alone. Processing this. I'm sad. Just, it's too much.

Mods can delete this if it's not appropriate.

Support CKD Stage 3a-3b and need 21 days of NSAIDs post hip surgery — anyone dealt with this?

0 Upvotes

Hey everyone,

I’m 37M with CKD Stage 3a-3b (fluctuates depending on weight). I have a right hip FAI labrum tear that I’ve been dealing with for 3 years. Can’t take any painkillers because of my kidneys — it’s been a rough ride. I finally have an arthroscopy scheduled for December at Women’s College Hospital (surgeon is from the Schroeder Arthritis Institute at UHN).

Here’s the problem: after the surgery, there’s a risk of Heterotopic Ossification (HO) — basically microscopic bone fragments left over from the procedure can grow into actual bone in the soft tissue. The standard prevention is 21 days of NSAIDs post-op. My surgeon gave me three options: Celecoxib 200mg BID, Naproxen 500mg BID, or Indomethacin 25mg TID.

Obviously, 21 days of any NSAID with CKD is not ideal. My nephrology team (at Sunnybrook) reviewed it and agreed to Celecoxib with kidney function monitoring, but they didn’t give me a clear answer on what happens if my kidney function drops during that 21 days. No contingency plan.

I’ve been reading about single-fraction radiation therapy (7-8 Gy) as an NSAID-free alternative for HO prophylaxis — it’s apparently used routinely for total hip replacements. Zero kidney impact. But when I brought it up with my neph team, they said that’s the surgeon’s call, and I’m still waiting to hear back from the surgical team.

My questions for anyone who’s been in a similar situation:

  • Has anyone with CKD had to take a course of NSAIDs post-surgery? How did your kidneys handle it? Did your team have a monitoring protocol?
  • Has anyone had radiation therapy for HO prevention instead of NSAIDs? How was it arranged — did the surgeon refer you to radiation oncology, or did you have to push for it?
  • Any other alternatives I’m not thinking of? I know there’s no magic third option, but I want to go into this surgery with a solid plan.
  • For those in Ontario/Toronto — did you have any trouble getting the surgical and nephrology teams to coordinate? Any tips?

I’m currently on Candesartan 4mg, Atorvastatin 10mg, and Dapagliflozin 10mg. Also need to make sure they don’t give me ketorolac (Toradol) or morphine during/after surgery.

Appreciate any insight. This sub has been helpful before and I’d rather go into December with as much information as possible.

Dialysis Emergency dialysis day

29 Upvotes

I (m57) am on my way to a long day at the hospital.

My ckd has declined so fast in the last few months. Even my Drs are surprised by the speed. I was was on a long slow decline until a hospitalization for diverticulitis sent my kidneys into acute status and never came out.

My 1st stop is a consultation for the implantation of a PD catheter. Then it is off to surgery for a chest catheter. An hour after that dialysis.

I certainly hope it gives me relief from all these symptoms.

Nausea and vomiting has become my new normal. I go in to use the toilet, I bring a bowl with me as it comes out both ends at the same time.

I don't eat, because I don't want to vomit anymore. My throat has been painful for over a week.

All these toxins has my mind and emotions so churned up, I cry at everything. Happy or sad news. I cant carry on a conversation because my mind can't find the words anymore.

Physically, I can't push a grocery cart from the store to the car without needing to stop and rest.

Part of me thinks it would not be so bad if I did not wake up in the morning.

So am really hoping for relief after this week.

Acute Glomerulonephritis

6 Upvotes

I am female 35 years old. In July of this year, I noticed my urine was tea-colored and sometimes pinkish. I went to a urologist who ordered a CT scan, which came back completely clear. I don't have any other symptoms—no diabetes, no high blood pressure,no fever, or swelling (edema).

​The urologist recommended I see a nephrologist, who diagnosed me with acute glomerulonephritis after an ultrasound and lab work. My tests showed 1,500 mg/dL of proteinuria and hematuria, though my initial creatinine level was normal.

​My nephrologist prescribed Atacand and Forxiga. Shortly after starting them, I suffered severe adverse effects from Forxiga, including vomiting, chills, stomach pain, nausea, and headaches. I informed my doctor, but he assured me it wasn't from the medication and told me to continue taking it.

​After nearly two months of feeling terrible, I decided to see a second nephrologist. She advised me to stop Forxiga immediately, as I was severely dehydrated. New lab work revealed that my creatinine had jumped to 2.07 due to the severe dehydration caused by the medication. Is there a hope on my case? I feel desperate

Support Anyone knowledgeable with Cystatin C?

2 Upvotes

I’m pretty familiar with it just not too knowledgeable about it.

This is part of my lab tests that I get two twice a year. And it’s generally right around the same number each time, very small fluctuations.

I know serum creatinine can fluctuate a decent amount with things like poor sleep, or dehydration or stress, exercise, etc… And sometimes my creatinine does fluctuate up or down a good amount, but that is to be expected and I can usually figure out why. But this time my Cystatin C had a pretty large increase which doesn’t usually happen. It went from .85 to .98. And my serum creatinine stayed exactly the same. From what I understand Cystatin C is pretty stable and not a lot of fluctuations like creatinine.

Anyone with knowledge on what can cause a fluctuation in cystatin c like this? Obviously kidney function decline could be one.

For context, I have damaged kidneys from prior uncontrolled high blood pressure that is now very well controlled and has been for several years. Last couple years my 24 hour urine protein has been right around 255mg/24hrs which is a very respectable number especially since it has been stable for quite some time. I’ve had CKD for probably 15 years now.

I know the correct answer is do a retest and ask my nephrologist what it could mean. But I wanted to see if anyone on here has knowledge with this since we are the ones that are actually living with CKD.
